Waterstop has a singular purpose: To prevent the passage of fluids across and along concrete joints. This page is dedicated to all things waterstop, as used to seal joints in concrete construction. Feel free to post any comments or questions and I will answer promptly.
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.

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.
