<p style="color: #0d0d14; font-family: "Helvetica Neue Light"; font-stretch: normal; line-height: normal; margin: 0px; text-align: left;">You can quantify the effectiveness of a waterstop by calculating its fluid flow path. The fluid flow path is measured from the waterstop hydraulic side to the dry side. Ribbed waterstop profiles are much more effective than the traditional dumbbell varieties. The series of fins (or ribs) substantially exaggerates the fluid flow path from the hydraulic side to the dry side compared to the older standard dumbbell profiles (see the illustration below).</p><p style="color: #0d0d14; font-family: "Helvetica Neue Light"; font-stretch: normal; line-height: normal; margin: 0px; text-align: left;"><br /></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi3X-PaQjMmRFHjiBVEL3mYbB9SNnw5_QghFhcQH5ldp4fTtkUEZNox_luh9_j0rMXd4nfkiLvIMMC8eXk3VgbN6Obv7igGNkitU3ipUfNYgModugS1u7RFPnpy98xbDPOXhr_MQC8BbUF4QLqGmtFBPuD5EFTdk8R_f5DveH3qtJDxVTPMTQ/s1928/2022%20Fluid%20Flow%20Path.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1082" data-original-width="1928" height="225" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi3X-PaQjMmRFHjiBVEL3mYbB9SNnw5_QghFhcQH5ldp4fTtkUEZNox_luh9_j0rMXd4nfkiLvIMMC8eXk3VgbN6Obv7igGNkitU3ipUfNYgModugS1u7RFPnpy98xbDPOXhr_MQC8BbUF4QLqGmtFBPuD5EFTdk8R_f5DveH3qtJDxVTPMTQ/w400-h225/2022%20Fluid%20Flow%20Path.png" width="400" /></a></div><br /><p style="color: #0d0d14; font-family: "Helvetica Neue Light"; font-stretch: normal; line-height: normal; margin: 0px; text-align: left;"><br /></p>David R.

TPER, TPO, and TPV?<h2 style="text-align: left;"><span style="font-family: helvetica;">Understanding the difference between TPER and TPV is the key to writing more robust specifications for chemical-resistant waterstop. The key is in the crosslinking of the rubber phase. Polymers are chemical compounds formed by multiple structural units called monomers.</span></h2><p><span style="font-family: helvetica;">In the laboratory, forming polymers from monomers is called polymerization and is often so complex that it has to be initiated or sustained by heat, pressure, or a catalyst. Synthetic polymers produce plastics, synthetic fibers, and synthetic rubber.</span></p><p><span style="font-family: helvetica;">Polymers come in different forms and have certain qualities (strength, elasticity, resistance to solvents, and temperature extremes), achieved through vulcanization, where individual polymer molecules form crosslinks.</span></p><p><span style="font-family: helvetica;">The vulcanization of polymers leads to springy rubber molecules that can become locked together to a greater or lesser extent. These molecules form rubber or elastomers. The end material is stronger, much more durable, and more resistant to chemicals.</span></p><p><span style="font-family: helvetica;"> </span></p><p><span style="font-family: helvetica;"><u>ELASTOMERS</u></span></p><p><span style="font-family: helvetica;">Elastomers are amorphous polymers, the result of crosslinking rubber molecules through vulcanization.</span></p><p><span style="font-family: helvetica;">
</span><span style="font-family: helvetica;">An elastomer can exist in two states:</span></p><p><span style="font-family: helvetica;">• Uncured elastomers are a gelatinous mass with the consistency of chewing gum in its natural state.</span></p><p><span style="font-family: helvetica;">• Cured elastomers (i.e., vulcanized elastomers) are rubber-like materials that can be stretched to twice their original length. Thanks to their crosslinks, they return to most of their original length when released.</span></p><p><span style="font-family: helvetica;"> </span></p><p><span style="font-family: helvetica;"><u>PLASTICS</u></span></p><p><span style="font-family: helvetica;">Plastic or thermoplastic polymers consist of long polymer molecules that are not linked to each other, i.e.; they have no crosslinks. They can generally go through many melt/freeze cycles without suffering chemical change.</span></p><p><span style="font-family: helvetica;">
</span><span style="font-family: helvetica;">Thermoplastics include polyethylene, polypropylene, polystyrene, polyester, polyvinyl chloride, acrylics, nylons, and polyurethanes.</span></p><p><span style="font-family: helvetica;">
</span><span style="font-family: helvetica;">Fundamental differences exist between thermoplastic polymers and thermoset rubber. Thermoset rubber generally demonstrates a better elastic behavior and a better memory than a thermoplastic material. They are also better suited to high-temperature applications. Thermoset rubber is not easily recyclable like thermoplastic, which can be melted and reshaped.</span></p><p><span style="font-family: helvetica;"> </span></p><p><span style="font-family: helvetica;"><u>THERMOSET RUBBER</u></span></p><p><span style="font-family: helvetica;">Thermoset rubber refers to a range of elastomers that vulcanize to a more robust form through the addition of energy (heat or irradiation). The added power and catalysts cause the molecular chains to link into a rigid, 3D structure. However, once vulcanized, they cannot be melted and reshaped.</span></p><p><span style="font-family: helvetica;">Important thermosets include phenolics, urea, melamine, epoxies, polyesters, silicones, rubbers, and polyurethanes.</span></p><p><span style="font-family: helvetica;"> </span></p><p><span style="font-family: helvetica;"><u>THERMOPLASTIC ELASTOMERS (TPER)</u></span></p><p><span style="font-family: helvetica;">Thermoplastic elastomers (TPERs) are a diverse family of rubber-like compound materials that combine the functional performance and properties of conventional thermoset rubbers with the processability of plastics. TPERs permit the fabrication of rubber-like products with the ability to be reshaped or reformed with the application of heat.</span></p><p><span style="font-family: helvetica;"> </span></p><p><span style="font-family: helvetica;"><u>THERMOPLASTIC VULCANIZATES (TPV)</u></span></p><p><span style="font-family: helvetica;"><a href="https://www.jpspecialties.com/waterstop-products/tpv-waterstop/" target="_blank">Thermoplastic vulcanizates (TPVs)</a> belong to the thermoplastic elastomer (TPER) family. TPVs are chemically crosslinked rubber within a thermoplastic polymer phase.</span></p><p><span style="font-family: helvetica;">The level of vulcanization (partial versus full) has an impact on the properties of the TPV. A fully vulcanized TPV demonstrates improved performance than a partially or non-vulcanized one (thermoplastic polyolefin or TPO).</span></p><p><span style="font-family: helvetica;">TPVs have outstanding properties, including excellent elastic recovery, high-temperature resistance, and chemical resistance.</span></p><p><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto;"><tbody><tr><td style="text-align: center;"><a href="https://1.bp.blogspot.com/-7MofhhFlW0g/YU5NWunxjeI/AAAAAAAACek/1b8mx30-lIsmCRj2nrdSsMS7KVeLkPgMwCLcBGAsYHQ/s1000/TPV%2BMolecule.jpeg" imageanchor="1" style="margin-left: auto; margin-right: auto;"><img border="0" data-original-height="750" data-original-width="1000" height="300" src="https://1.bp.blogspot.com/-7MofhhFlW0g/YU5NWunxjeI/AAAAAAAACek/1b8mx30-lIsmCRj2nrdSsMS7KVeLkPgMwCLcBGAsYHQ/w400-h300/TPV%2BMolecule.jpeg" width="400" /></a><br /><span style="background: var(--artdeco-reset-base-background-transparent); color: var(--color-text-low-emphasis); font-size: var(--artdeco-reset-typography_getFontSize);">A TPV molecule — Crosslinked rubber phase encased in a thermoplastic matrix.</span></td></tr></tbody></table></p><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto;"><tbody><tr><td class="tr-caption" style="text-align: center;"><div class="relative reader__grid" style="background: var(--artdeco-reset-base-background-transparent); border: var(--artdeco-reset-base-border-zero); box-sizing: inherit; float: none; font-size: var(--artdeco-reset-base-font-size-hundred-percent); margin: var(--artdeco-reset-base-margin-zero); overflow-wrap: break-word; padding: var(--artdeco-reset-base-padding-zero); position: relative !important; text-align: start; vertical-align: var(--artdeco-reset-base-vertical-align-baseline); width: 744px;"><header aria-label="Newsletter header" id="reader-article-header" style="background: var(--artdeco-reset-base-background-transparent); border: var(--artdeco-reset-base-border-zero); box-sizing: inherit; caret-color: rgba(255, 255, 255, 0.9); color: rgba(255, 255, 255, 0.9); display: var(--artdeco-reset-base-display-block); font-family: -apple-system, system-ui, BlinkMacSystemFont, "Segoe UI", Roboto, "Helvetica Neue", "Fira Sans", Ubuntu, Oxygen, "Oxygen Sans", Cantarell, "Droid Sans", "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Emoji", "Segoe UI Symbol", "Lucida Grande", Helvetica, Arial, sans-serif; font-size: 16px; margin: var(--artdeco-reset-base-margin-zero); padding: var(--artdeco-reset-base-padding-zero); vertical-align: var(--artdeco-reset-base-vertical-align-baseline);"></header><br class="Apple-interchange-newline" /></div></td></tr></tbody></table><p><br /><span style="font-family: helvetica;"><br /></span></p><p><span style="font-family: helvetica;"> </span></p><div><br /></div>David R.

At their most basic level, hydrophilic waterstops absorb moisture, grow in size, and seal the concrete construction joint.</span></span></p><p style="color: #0e101a; margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: helvetica;"><br /></span></p><p style="color: #0e101a; margin-bottom: 0pt; margin-top: 0pt;"><span data-preserver-spaces="true" style="margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: helvetica;">Hydrophilic waterstops sell in rolls or strips. The profile is usually a small rectangle or trapezoidal shape, with 3/4” x 1” being somewhat standard. These strips are adhered to existing concrete using an adhesive or primer, or alternately concrete nails at 12” on-center spacing. This adhesion is essential, as only three sides of the waterstop get exposed to fresh concrete. If the waterstop displaces during the concrete pour, it can quickly lose most of its effectiveness. </span></span></p><p style="color: #0e101a; margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: helvetica;"><br /></span></p><p style="color: #0e101a; margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: helvetica;"><span data-preserver-spaces="true" style="margin-bottom: 0pt; margin-top: 0pt;">Commercially available for several decades, hydrophilic waterstops have long track records, </span><em style="margin-bottom: 0pt; margin-top: 0pt;">albeit not always positive</em><span data-preserver-spaces="true" style="margin-bottom: 0pt; margin-top: 0pt;">. Take great care at the specification level to ensure your project meets this range of product’s relatively narrow application scope.</span></span></p><p style="color: #0e101a; margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: helvetica;"><br /></span></p><p style="color: #0e101a; margin-bottom: 0pt; margin-top: 0pt;"><strong style="margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: helvetica;">Hydrophilic Waterstops — The “Pros”</span></strong></p><p style="color: #0e101a; margin-bottom: 0pt; margin-top: 0pt;"><span data-preserver-spaces="true" style="margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: helvetica;">The most significant advantage of hydrophilic waterstops is their ease of installation — the products get glued in place at the cold joint, and concrete is then cast on top of them (the second pour). The installation efficiency of this class of products makes them a favorite amongst contractors in the field.</span></span></p><p style="color: #0e101a; margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: helvetica;"><br /></span></p><p style="color: #0e101a; margin-bottom: 0pt; margin-top: 0pt;"><span data-preserver-spaces="true" style="margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: helvetica;">Another “pro” is their relatively low cost. At the time of publication, a “typical” sodium bentonite-based waterstop is approximately $2.00 per linear foot, and a “typical” chemical-modified chloroprene rubber waterstop is $6.00 per linear foot. When combined with the low labor cost, strip-applied hydrophilic waterstops are time and money savers.</span></span></p><p style="color: #0e101a; margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: helvetica;"><br /></span></p><p style="color: #0e101a; margin-bottom: 0pt; margin-top: 0pt;"><strong style="margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: helvetica;">Hydrophilic Waterstops — The “Cons”</span></strong></p><p style="color: #0e101a; margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: helvetica;"><span data-preserver-spaces="true" style="margin-bottom: 0pt; margin-top: 0pt;">To read the manufacturer’s product literature, you would think they are indeed the perfect waterstop product. Cheap and easy to install, high head pressure-resistant, and low material cost. These products are not the panacea the manufacturers claim, and the essential information concerning their use is often not published. For instance, a leading manufacturer of hydrophilic waterstop states the following </span><em style="margin-bottom: 0pt; margin-top: 0pt;">minimum requirements</em><span data-preserver-spaces="true" style="margin-bottom: 0pt; margin-top: 0pt;"> on their datasheet:</span></span></p><ol style="color: #0e101a; margin-bottom: 0pt; margin-top: 0pt;"><ol style="margin-bottom: 0pt; margin-top: 0pt;"><li class="ql-indent-1" style="list-style-type: lower-alpha; margin-bottom: 0pt; margin-top: 0pt;"><span data-preserver-spaces="true" style="margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: helvetica;">8-inch thick concrete or greater</span></span></li><li class="ql-indent-1" style="list-style-type: lower-alpha; margin-bottom: 0pt; margin-top: 0pt;"><span data-preserver-spaces="true" style="margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: helvetica;">A double row of reinforcing steel</span></span></li><li class="ql-indent-1" style="list-style-type: lower-alpha; margin-bottom: 0pt; margin-top: 0pt;"><span data-preserver-spaces="true" style="margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: helvetica;">3,000 psi concrete or greater</span></span></li><li class="ql-indent-1" style="list-style-type: lower-alpha; margin-bottom: 0pt; margin-top: 0pt;"><span data-preserver-spaces="true" style="margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: helvetica;">3 inches of concrete coverage on all sides of the waterstop (minimum)</span></span></li><li class="ql-indent-1" style="list-style-type: lower-alpha; margin-bottom: 0pt; margin-top: 0pt;"><span data-preserver-spaces="true" style="margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: helvetica;">Non-moving construction joints only</span></span></li></ol></ol><p style="color: #0e101a; margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: helvetica;"><br /></span></p><p style="color: #0e101a; margin-bottom: 0pt; margin-top: 0pt;"><span data-preserver-spaces="true" style="margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: helvetica;">These requirements seriously limit the project designer. Few concrete projects consist of just construction joints, and eight-inch thick concrete is rare in residential and light commercial construction. The first four prevent the hydrophilic reaction (waterstop swelling in the presence of water) from cracking or blowing out the concrete. The leading manufacturer of bentonite-based waterstops includes 75% sodium bentonite into the manufacture of their product. This high bentonite concentration allows the product to rapidly swell when exposed to water and quickly seal the joint. However, this high concentration of bentonite can also create problems such as concrete cracking or even the potential of blown-out joints due to the internal pressure of the rapidly expanding waterstop and the low tensile strength of uncured concrete.</span></span></p><p style="color: #0e101a; margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: helvetica;"><br /></span></p><p style="color: #0e101a; margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: helvetica;"><span data-preserver-spaces="true" style="margin-bottom: 0pt; margin-top: 0pt;">Another limitation is the product’s inability to swell as intended in fluids other than water. All of the commercially available hydrophilic waterstop products have published data for swell ratios; however, this data is for potable water (often distilled) and saltwater. Since the products need to swell to seal the concrete joint, a designer for a non-water facility (such as secondary containment of petroleum products) can not specify hydrophilic waterstops with confidence as they will not swell as intended and may deteriorate. </span><strong style="margin-bottom: 0pt; margin-top: 0pt;">The American Concrete Institute recommends against using hydrophilic waterstops for fluids other than water (ACI 350.2R-04)</strong><span data-preserver-spaces="true" style="margin-bottom: 0pt; margin-top: 0pt;">.</span></span></p><p style="color: #0e101a; margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: helvetica;"><br /></span></p><p style="color: #0e101a; margin-bottom: 0pt; margin-top: 0pt;"><strong style="margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: helvetica;">Hydrophilic Waterstops — Butyl/Bentonite</span></strong></p><p style="color: #0e101a; margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: helvetica;"><span data-preserver-spaces="true" style="margin-bottom: 0pt; margin-top: 0pt;">The first hydrophilic waterstops sold commercially were a mixture of clay and rubber. </span><a class="editor-rtfLink" href="http://en.wikipedia.org/wiki/Sodium_bentonite" style="color: #4a6ee0; margin-bottom: 0pt; margin-top: 0pt;" target="_blank"><span data-preserver-spaces="true" style="margin-bottom: 0pt; margin-top: 0pt;">Sodium bentonite clay</span></a><span data-preserver-spaces="true" style="margin-bottom: 0pt; margin-top: 0pt;"> is the hydrophilic component of the product. Butyl rubber serves as the cohesive, tacky base. </span></span></p><p style="color: #0e101a; margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: helvetica;"><br /></span></p><p style="color: #0e101a; margin-bottom: 0pt; margin-top: 0pt;"><span data-preserver-spaces="true" style="margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: helvetica;">Bentonite-based hydrophilic waterstops are susceptible to product disintegration over the long term, especially when the moisture or saturation conditions are cyclical. The continual expansion/shrinkage/re-expansion causes the products to break down, and the bentonite migrates from the butyl rubber, leaving a smaller, cracked, non-expandable product.</span></span></p><p style="color: #0e101a; margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: helvetica;"><br /></span></p><p style="color: #0e101a; margin-bottom: 0pt; margin-top: 0pt;"><span data-preserver-spaces="true" style="margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: helvetica;">Waterstop products containing less bentonite are less likely to break, blow out the concrete joint, and are less likely to break down over time from bentonite migration. However, they also swell slower and less volumetrically. Reduced bentonite waterstops should not be used in saltwater as their hydrophilic reaction is limited.</span></span></p><p style="color: #0e101a; margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: helvetica;"><br /></span></p><p style="color: #0e101a; margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: helvetica;"><span data-preserver-spaces="true" style="margin-bottom: 0pt; margin-top: 0pt;">Sodium bentonite-based hydrophilic waterstops are still commercially available today.

The effects may be a permanent contraction from drying shrinkage, carbonation, or creep, abnormal changes from chemical reactions of sulfate or alkali attacks, or merely applying a concrete load.</span></p><p style="color: #0e101a; margin-bottom: 0pt; margin-top: 0pt;"><br /></p><p style="color: #0e101a; margin-bottom: 0pt; margin-top: 0pt;"><span data-preserver-spaces="true" style="margin-bottom: 0pt; margin-top: 0pt;">As the concrete moves, it relieves the internal stresses by forming a crack. Engineer designers minimize the unsightly appearance of self-formed cracks by introducing joints into the concrete to accommodate the movement without losing structural integrity. </span></p><p style="color: #0e101a; margin-bottom: 0pt; margin-top: 0pt;"><br /></p><p style="color: #0e101a; margin-bottom: 0pt; margin-top: 0pt;"><span data-preserver-spaces="true" style="margin-bottom: 0pt; margin-top: 0pt;">Contraction joints divide large pours of concrete into smaller structural units. Contraction joints create a man-made plane of weakness to regulate and control the location of a crack formed by moisture loss of concrete. Without this formed contraction joint, the concrete would freely crack in unexpected and unattractive places.</span></p><p style="color: #0e101a; margin-bottom: 0pt; margin-top: 0pt;"><br /></p><p style="color: #0e101a; margin-bottom: 0pt; margin-top: 0pt;"><span data-preserver-spaces="true" style="margin-bottom: 0pt; margin-top: 0pt;">A scheduled or unscheduled interruption of the concrete pour 30 minutes or greater creates a construction joint.</span></p><p style="color: #0e101a; margin-bottom: 0pt; margin-top: 0pt;"><br /></p><p style="color: #0e101a; margin-bottom: 0pt; margin-top: 0pt;"><span data-preserver-spaces="true" style="margin-bottom: 0pt; margin-top: 0pt;">Designed to negate the compressive forces from abutting concrete structures that may occur due to expansion, loads, or differential movements, expansion joints require an actual gap between the concrete pours, filled with a compressible joint filler material such as foam, rubber, cork, or cane fiberboard.</span></p><p style="color: #0e101a; margin-bottom: 0pt; margin-top: 0pt;"><br /></p><p style="color: #0e101a; margin-bottom: 0pt; margin-top: 0pt;"><span data-preserver-spaces="true" style="margin-bottom: 0pt; margin-top: 0pt;">Waterstop is a preformed joint material, metallic or nonmetallic, designed to stop the migration of fluids by creating an internal dam running across and along concrete joints.</span></p><p style="color: #0e101a; margin-bottom: 0pt; margin-top: 0pt;"><br /></p><p style="color: #0e101a; margin-bottom: 0pt; margin-top: 0pt;"><span data-preserver-spaces="true" style="margin-bottom: 0pt; margin-top: 0pt;">Commercially available </span><a class="_e75a791d-denali-editor-page-rtfLink" href="https://www.jpspecialties.com/" style="color: #4a6ee0; margin-bottom: 0pt; margin-top: 0pt;" target="_blank"><span data-preserver-spaces="true" style="margin-bottom: 0pt; margin-top: 0pt;">waterstops</span></a><span data-preserver-spaces="true" style="margin-bottom: 0pt; margin-top: 0pt;"> are either metallic or nonmetallic.
