CSR-1100 Water Activated Polyurethane Foam

For sealing active leaks in above grade and below grade concrete structures such as: Water Treatment Tanks, Dams, Concrete Walls, Tunnels, Manholes, and Elevator Service Pits. Seals: Hairline Cracks, Wide Cracks, Pipe Joints, and Pipe Penetrations. Does not fix structural damage. Not intended for use in expansion joints.

Features & Packaging


•  Single Component
•  Extremely durable and flexible
•  Low viscosity allows for penetration into tight cracks
•  Up to 600% unconfined expansion
•  Application Temperature Range: 38°F to 130°F (3°C to 54°C)
•  Service Temperature Range: -30°F to +200°F (-34°C to +93°C)
•  Meets ANSI / NSF Standard 61 for Drinking Water

Packaging & Storage

Available in 10-ounce single component cartridges.  Custom packaging available upon request.
Storage: Store in dry environment between 40°F and 80°F. 
      Elevated temperatures will reduce shelf life.
Shelf Life: 18 months from date of manufacture for unopened, properly stored product.

Product Guidelines

Material Preparation:  Store material overnight to precondition to 70°F-80°F prior to use.

Reaction Procedures & Ratio:  Uses available water to initiate reaction. CSR-1100 reacts with 1 or 2 parts water.

Application Instructions:  See Installation Guidelines. Contact ConSeal for your application specific instructions.

Personal Protection:  Safety Glasses, gloves, avoid skin contact, do not ingest, for professional use only, see SDS. For use in well ventilated areas only to keep vapor concentrations low. Use mechanical ventilation if necessary. Use a self-contained breathing apparatus in confined space environments.

Cleanup:  Flush equipment with solvent based material. Clean off skin with soap and water. Mechanically remove cured material. Clean up unwanted, excess liquid product by reacting product with a small amount of water to cure and then dispose. Cured material is environmentally safe and can be disposed of in an approved landfill. 

Limitations:  Cold temperatures will slow down reaction time and increase viscosity of liquid product. No ice can be present in areas to be serviced. Wait for warmer weather or flush out ice with warm water prior to injecting CSR-1100. Acidic solutions below pH 3 and alkaline solutions above pH 10 may adversely affect foam properties.
