Joint Protection

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.

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 in concrete structures
  • Casting new concrete against existing
  • Joints between floor slabs and pile caps
  • Pipe penetrations through floors and walls
ADCOR® 550 T-MI
Description

ADCOR® 550 T-MI is a combined active and passive waterstop system with built in redundancy for the secure sealing of concrete construction joints subject to hydrostatic pressure. It comprises an outer hydrophilic sleeve activated in contact with water (active) for sealing the joint, and a reinforced injection tube for remedial treatment by resin injection (passive).

Key Benefits
  • A hydrophilic outer sleeve
  • A filtration membrane outside the reinforced inner tube
  • A steel wire reinforced inner tube
Application Type
  • Construction joints for in-situ concrete structures
  • Casting new concrete against existing concrete
  • Floor slabs cast against diaphragm retaining walls, steel sheet piles and secant piled walls
AT System: SERVITITE® AT 200/SERVISEAL® AT 240
Description

High security PVC waterstop system with coextruded hydrophilic bulbs to provide a unique combination of active and passive protection for joints in concrete

Key Benefits
  • Increased security
  • Continuously active sealing
  • Prevents water tracking
Application Type
BENTORUB® Salt
Description

BENTORUB® Salt is a red flexible hydrophilic strip of approx. 25 by 20 mm, made of natural sodium bentonite clay and synthetic rubber. 

Key Benefits
  • BENTORUB® Salt is a permanently active system, which swells up to approximately 2.5V in an 8% salt solution (*).
  • BENTORUB® Salt is an ecological and user friendly system: easy and quick installation by means of gun nailing or gluing with Bentoglue or MS Fixer.
  • The use of Bentosteel will help the installation and will protect the BENTORUB® Salt strip against damage during pouring or compaction of the concrete.
Application Type
  • BENTORUB® Salt is designed for sealing construction joints, cold joints and working joints in concrete, around pipe penetrations, in sewer joints, against slurry walls, sheet piling in contact with salt water and brackish water
  • BENTORUB® Salt may only be used in contact with salt and brackish water.
  • Can be used in combination with Infiltra Stop in situations, which are deemed to be high risk.
RE-INJECTO®
Description

Re-Injectable injection hose for consecutive injection with Omnitek Inject micro fine cement or Gelacryl resins

Key Benefits
  • Easy to re-inject using with OMNITEK Inject or Gelacryl resins
  • Simple installation using the special Twinbox end piece connector
  • The Re-injecto hose can withstand concrete pressures of up to 20 meters.
Application Type

Sealing cold and construction joints, pipe penetrations, joints between diaphragm walls and slabs through post-injection with Omnitek Inject micro fine cement or Gelacryl resin where consecutive re-injections are needed.

SERVISEAL®
Description

SERVISEAL® is a passive external PVC waterstop system manufactured in a range of sizes for protecting joints in concrete basements and sub-structures.

Key Benefits
  • Proven design - the original external waterstop used extensively in water excluding and water retaining structures
  • Flexible - will accommodate movement during construction and service life
  • External seal - protects reinforcement from water ingress
Application Type
  • SERVISEAL® can be used for non-suspended slabs in water retaining structures such as reservoirs, swimming pools and sewage treatment tanks.
SERVITITE®
Description

SERVITITE® is an internally cast specially formulated PVC waterstop system manufactured in a range of sizes for use in reinforced concrete structures.

Key Benefits
 
  • Promotes better anchorage and embedment into concrete and simplifies site jointing
  • Accommodates large movements during construction and service life
  • Remains flexible at low temperatures

PVC Edgetie™
Description

PVC EDGETIE™ is an internally cast passive waterstop system manufactured in a range of sizes for sealing joints in concrete structures subject to water pressure.

Key Benefits
  • Promotes concrete compaction and simplifies site jointing
  • Accommodates movement during construction and service life
  • Provides positive anchorage for tying wires fastened through reinforced wiring holes
Application Type
  • Used at all joints to prevent the ingress of moisture using only factory produced fabrications for changes of direction or profile with site jointing limited to simple butted welds
Overview

The GCP advantage

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.

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.
