Concrete Joints and Waterstop

Over its long lifespan, concrete is subject to physical changes in length, width, height, and volume of its mass when subjected to environmental changes and mechanical conditions surrounding it. 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.

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. 

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.

A scheduled or unscheduled interruption of the concrete pour 30 minutes or greater creates a construction joint.

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.

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.

Commercially available waterstops are either metallic or nonmetallic. Metallic waterstops possess high strength and extreme heat and cold resistance but offer little extensibility. Nonmetallic (plastic, rubber) waterstops provide flexibility rather than strength and have good extensibility, recovery, chemical resistance, and fatigue resistance.

MSI Process for Waterstops

Waterstop has a singular purpose: To prevent the passage of fluids across and along concrete joints. Waterstop does all of its work at the joint. Because concrete joints are frequently open and subject to hydrostatic loads, waterstop has the most critical role in fluid-proofing a concrete structure. A pinhole or imperfection in a vapor barrier will have little to no noticeable effect. Still, even the slightest defect in the waterstop product or its installation can be truly catastrophic to the fluid-tight integrity of the building envelope. For this reason, a great deal of care must go into what I call the MSI Process: Manufacturing, Selection, and Installation.

Waterstop MSI Process

  1. Waterstop MANUFACTURING, history, and types of products commercially available. The manufactured waterstop must be of the highest quality from a manufacturer offering specification, detailing, and installation assistance.
  2. Waterstop product SELECTION is the second most important consideration. Profiles are available for myriad applications and conditions. The designer must choose correctly, preferably with manufacturer consultation.
  3. Waterstop INSTALLATION. Most waterstop failures occur because the material incorrectly installed.

Concrete Contractors — Save Time and Money with the ST-10® Waterstop Splicing Table

The ST-10® Waterstop Splicing Table by J P Specialties, Inc.

The ST-10® was designed and patented by J P Specialties as the perfect solution for producing high-tensile strength, leakproof welds on thermoplastic waterstops such as PVC, HDPE, LDPE, TPER, and TPV. New quality assurance standards in today’s waterstop specifications mandate tensile testing across field welded joints, usually requiring tensile strength 80% or better of the parent material. Waterstops welded with the ST-10® assure the Contractor that their workmanship will yield results conducive to these rigorous requirements. The ST-10® is also an extreme labor saver, taking a two-man job — welding waterstop — and taking it down to just one man.

  • Easy to use
  • Aligns the waterstop
  • Portable, lightweight
  • Weather resistant
  • Minimizes fumes (maximizes safety)
  • High tensile welds
  • Welds under pressure, eliminating air bubbles
