Product Description

GELACRYL™ Acrylic Rubbers are 2-component poly-acrylate gels. The A-component is a poly-acrylate resin, the B-component is a polymer blend. The 2-components are injected with a 2-component 1:1 ratio piston pump. Once polymerised, GELACRYL™ Acrylic Rubbers form a resilient, highly elastomeric gel. Due to their exceptionally low viscosity and low surface tension, GELACRYL™ Acrylic Rubbers show better penetration into cracks than water

  • Resin = GELACRYL™/GELACRYL™ SR/GELACRYL™ Superflex
  • Polymer blend = GELACRYL™ AR2
  • Catalyst = TE 300
  • Initiator = SP 200
  • Decelerator = KF 500

Product Advantages

  • GELACRYL™ AR injection systems are injected with a twin piston, 1:1 ratio pump.
  • Exceptionally low viscosity. GELACRYL™ AR penetrates into cracks 0.1 mm wide.
  • Excellent post-expansion properties in contact with water.
  • GELACRYL™ AR does not need continuous contact with water.
  • Excellent adhesion to concrete when GELACRYL™ Superflex is used.
  • Very good chemical resistance to most acids, alkalis and biological attack (*).
  • Can be used in temperatures ranging from 5°C to 70°C.
  • Poly-acrylate resin, free of acryl-amides.

(*) For chemical resistances please contact your GCP representative.

Field of Application

GELACRYL™ Acrylic Rubbers are used in applications where fluctuating groundwater levels are encountered. The addition of the polymer blend in the B-component improves the wet-dry characteristics of the cured compound.

GELACRYL™/GELACRYL™ Superflex

  • Remedial repair of water leaks.
  • Preventative waterproofing of structures.
  • Water control during tunnelling operations.
  • Curtain grouting.
  • Waterproofing subterranean structures in concrete or masonry (cellars, underground car parks, etc.).
  • Waterproofing cracks in concrete or rock.
  • Waterproofing tunnel segments.
  • Waterproofing tunnel liners.
  • Dilatation joints with small dilatation (GELACRYL™ Superflex)

GELACRYL™ SR

  • Sewer joint repair (automated or manual).
  • Water control during tunnel operations.
  • Waterproofing of underground concrete or masonry structures

Application

Consult the Material Safety Data Sheet (MSDS) before mixing and/or handling.

  • GELACRYL™ Acrylic Rubbers are developed to be used below ground in applications with a fluctuating groundwater level.
  • Holes are drilled in the affected area.
  • Water can be forced into the hole to determine whether all cracks can be injected and if additional injection/pressure control holes need to be drilled.
  • Visible surface leaks and cracks should be sealed with a fast setting cement prior to injection. Allow the cement to harden completely before injecting GELACRYL™ Acrylic Rubbers.
  • Use standard packers or equipment according to local standards.
  • GELACRYL™ Acrylic Rubbers is then injected into the holes with a high pressure pump capable of reaching pressures up to 200 bars. This forces the GELACRYL™ Acrylic Rubber deep into the structures and allows penetration into the smallest cracks.
  • When surface leaks show up during pumping, stop immediately and seal the leak by approved method.

1. Composition

  • The injection grout needs to be prepared immediately before the injection.
  • Both components are pre-weighted, no further dilution of component 2 with water is required. Prior to injection only the additives need to be added to both components.
  • After preparation, the components are injected simultaneously in a ratio of 1:1.

2. Preparation

Component 1

  • Add the required quantity of TE 300 catalyst to the GELACRYL™ resin. GELACRYL™ resin and TE 300 need to be thoroughly mixed. In case of using GELACRYL™ SR, an additional amount of water needs to be added to Component 1.

Component 2

  • The tank is first filled with the same quantity of GELACRYL™ AR2. Then slowly and under continuous mixing to avoid lumps, add the required quantity of SP 200. Mix well at 600 rpm.
  • The components should only be prepared immediately before use of the grout. We do not recommend preparation in advance.
  • As soon as temperatures of the environment or material reach 20°C or higher, the resin and grout need to be regularly oxygenated by passing compressed air through the containers
