Waterstops

Flexible waterproofing for concrete joints.

Waterstops represent a critical component of any waterproofing system. Due to shrinkage and settling, the surfaces of a concrete cold joint will never perfectly conform to one another. Without a flexible barrier that can accommodate the imperfections  of concrete surfaces, water will have the opportunity to creep in through the seam.

Our waterstops are specifically designed to resist job-site conditions while outperforming other solutions. These waterstops offer innovative technology options  to meet a wide variety of project needs. This includes tricky or problematic installations where technical finesse is required. No matter the project, we have a waterstop that’s ideal for the job.

ADCOR® 500T
Description

ADCOR® 500T is a unique product that has been specifically developed to provide higher performance than conventional bentonite or swellable rubber waterstops.

Key Benefits
  • Controlled volumetric expansion
  • Conformable
  • Retains cohesive strength at both original and expanded volume.
  • No need for protective steel mesh.
Application Type
  • Horizontal and vertical construction joints
  • Casting new concrete against existing
  • Floor slabs cast against diaphragm retaining walls, steel sheet piles and secant pile walls
ADCOR® ES
Description
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.
Key Benefits
Controlled, reproducible, volumetric expansion Cohesive strength maintained after volumetric expansion and during wet-dry cycling Malleable and plastic
Application Type
Joints de construction horizontaux et verticaux dans des structures en béton Nouveau coulage sur béton existant Percée de conduite dans les planchers et les parois
Adcor® SAS 500S
Description
Le ADCOR® SAS 500S est un arrêt d'eau hydrophile dilatable qui fournit une liaison continue aux substrats, empêchant l'entrée d'eau par les joints dans les sous-constructions en béton. Il permet une installation rapide dans tout assemblage de construction, ce qui en fait une excellente alternative à la fixation avec clous et maillages.
Key Benefits
Continuous bond to substrates Quick installation in any construction assembly Provides a faster water stop application and higher performance than conventional bentonite or other swellable rubber waterstops
Application Type
Construction joints in in-situ concrete structures Nouveau coulage sur béton existant Floor slabs cast against diaphragm retaining walls, steel sheet piles and secant piled walls Joints entre les dalles de plancher et les structures de liaison Percée de conduite dans les planchers et les parois Remedial ‘breaking out’ of concrete Vertical, overhead, soffit, horizontal locations
DE NEEF® INJECTO® SIS Tube
Description

The Small Injection System (SIS) INJECTO® is an injectable waterstop system that provides a conduit for the placement of DE NEEF® chemical grouts. Like its big brother the Injecto hose, the SIS hose is a permeable tube designed to ensure even distribution of grout throughout the injection zone.

Key Benefits
  • Small hose diameter
  • Fast, simple installation
  • No special tools required
  • Low pressure injection
  • Permanent seal after injection
  • Injectable anytime after concrete cure
Application Type
  • Sealing cold and construction joints
  • Sealing pipe penetrations
  • Sealing joints between slurry walls and slabs
INJECTO®
Description

INJECTO® is an injectable waterstop system that provides a conduit for the placement of GCP Applied Technologies chemical grouts.

Key Benefits
  • Fast, simple installation
  • No special tools required
  • Low pressure injection
Application Type
  • Sealing cold and construction joints
  • Sealing pipe penetrations and details
  • Sealing joints between slurry walls and slabs
TRIOject
Description

TRIOject is a multiple injection grout hose. It consists of three injection channels capable of being grouted independently. Each channel can be injected as needed through a Vario Packer. Pressure activated apertures on the top and bottom of the channels allow the injected grout to permeate the joint. The foam pad on the bottom assures continuous access to the concrete surface.

Key Benefits
  • Three independent injection channels
  • Pressure activated apertures
  • Durable construction
  • Wire mesh for additional protection
  • Foam pad adapts to irregular surface
Application Type

Sealing of construction joints, cold joints and working joints in concrete, where reinjection may be necessary

Overview

Waterstop Solutions

Our solutions incorporate advanced materials that prevent water infiltration in ways that other waterstops can't.  Novel engineering technologies result in waterstops that conform more securely to concrete surfaces, last longer, and provide more flexibility to contractors. For more information about these and other waterstop solutions, contact GCP today.

ADCOR®

An advanced hydrophilic waterstop that's compatible with all of our  industry-leading waterproofing membranes. ADCOR® is engineered to expand when it comes in contact with water. The material seals against concrete faces when encapsulated, and resists water infiltration through a cold joint.

INJECTO® Tube Groutable Hose Waterstop System

An injectable waterstop system that provides a passageway for a variety of chemical grouts. The system is designed to be laid down before concrete is poured, but not injected until well after it has cured. This allows the cracks created by shrinkage during the curing process to fully open. The resulting interfaces and voids can then be permanently sealed.

TRIOject® Multiple Grout Injection Hose

Comprised of a three-channel PVC-hose, TRIOject® allows for multiple grout injections in a more durable enclosure. Each of the three grout channels contains micro holes that prevent water from getting in, but allow grout to escape. The system is protected by a steel mesh on top, as well as a foam pad on the bottom that conforms to the concrete surface.  Crucially, the three-channel TRIOject® design lets builders in ject the same cold joint multiple times—a best-in-class solution for a critical or problematic application.
