Overview
A cold joint is where a fresh batch of concrete meets one that has already been cured. It’s hard for uncured concrete to form a seal with a block that’s been cured already. Therefore, a cold joint is the area where cracks are more likely to form, followed by water infiltration. For below-grade construction, waterstops represent a safe, commonsense approach to preventing water infiltration through seams in concrete.

ADCOR® 500S waterstop is a conformable, butyl rubber-based hydrophilic waterstop strip that expands in contact with water.
- Controlled volumetric expansion reduces risk of concrete spalling
- Retains cohesive strength at both original and expanded volume
- Malleable and conformable, enabling easy application to a variety of concrete profiles and a variety of irregular substrates
- Construction joints in in-situ concrete structures
- Casting new concrete against existing
- Floor slabs cast against diaphragm retaining walls, steel sheet piles and secant piled walls
- Joints between floor slabs and pile caps
- Pipe penetrations through floors and walls

ADCOR® ES is a specially engineered, swellable, conformable synthetic waterstop strip that expands when in contact with water. The engineered swell design of ADCOR® ES minimizes the potential for concrete spalling and cracking versus traditional hydrophilic waterstops.
- Controlled, reproducible, volumetric expansion
- Cohesive strength maintained after volumetric expansion and during wet-dry cycling
- Malleable and plastic
- Horizontal and vertical construction joints in concrete structures
- Casting new concrete against existing
- Pipe penetrations through floors and walls
