Waterstops

Flexible waterproofing for concrete joints.

Overview

The way to a better waterstop

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.

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®

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.

Description

The Small Injection System (SIS) DE NEEF® 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
