Three New Waterstop Profiles for Environmental Engineered Concrete Structures

Earth Shield Waterstop is proud to announce three new waterstop profiles designed especially for environmental engineered concrete structures, such as waste and water treatment plants. All three profiles are ⅜" thick and have many interlocking ribs to grab into freshly poured concrete. Highlights of the new profiles include:
  • NSF 61 Certified for drinking water
  • Chemical resistant TPV polymer construction
  • Ozone resistant to 500 PPHM
  • UV resistant
  • Heat weldable thermoplastic
The new profiles can be downloaded in our CAD Library located here.

JP336L Retrofit Waterstop System — Installed in Concrete Joint Designs Where Space is Limited

Earth Shield JP336L Retrofit System — JP336L is designed primarily for non-moving construction joints, although it can handle limited joint movement due to the mechanical properties of the parent material. A primary advantage of JP336L is that the fastening leg on the waterstop can be field-trimmed to 1-1/2” — the size of the stainless steel batten bar. Therefore, JP336L takes up very little room within a joint making it perfect for retrofitting thin slabs or containment curbs.

JP336L Retrofit Waterstop
One (1) 10 lft length of “L” Shaped TPV Waterstop
One (1) 10 lft length of 3/16” x 1-1/2” Stainless Steel Batten Bar
Twenty (20) Stainless Steel Anchor Bolts (size: 2-1/4” x ¼”)

Labyrinth Waterstop

Labyrinth waterstops are double-headed nailed to the formwork; therefore, obviating the need to split the formwork to accommodate one half of the waterstop. Because of their keyway-like shape and multitudinous miniature ribs they do an adequate albeit not stellar job of preventing the passage of water through non-moving construction joints.

Because of their non-symmetrical geometry they are very limited in regards to changes of directions.

The Little Book of Waterstop, as Featured in Concrete International

We're pleased to be featured in the November 2013 issue of Concrete International — the official magazine of the American Concrete Institute.

Our waterstop reference manual, The Little Book of Waterstop, is featured on page 61 and the brief review is appreciated. However, the review incorrectly lists this blog as the download site for the free iPad book, when in fact the correct download location is here
