CHEM-CRETE® TERRA FOAM CCC528

Hydro Active Soil Stabilization Polyurethane Grout

Chem-Crete Terra Foam CCC528 is a two component, low viscosity 100% solids and hydro active polyurethane grout, used for soil stabilization and increasing the bearing capacity of sandy soils. Chem-Crete Terra Foam CCC528 is hydro active, reacts quickly in contact with water to expand into a tough closed cell polyurethane foam.

USES

Chem-Crete Terra Foam CCC528 is extensively used for Soil Stabilization and increasing the bearing of sandy soils. It can be used around tunnel headings to improve the bearing and tunneling characteristics of the soil structure. Chem-Crete Terra Foam CCC528 is used in application such as:

 

  • Airports and Airfields
  • Sands dune, pipe lines, etc.
  • Highways and roadways, to prevent soil erosion on the bounds.
  • Tunnels, bridge sides, etc.
  • Power plants, sub-stations, etc.

ADVANTAGES

  • Two components ready-to-use work packs.
  • Solvent-free.
  • Hydro active, only reacts upon contact with water.
  • Expands to a tough closed cell polyurethane foam.
  • Low viscosity, permits reliable penetration

APPLICATION

Limitations: Application at ambient temperature below 4.4°C is not recommended. Exposure to temperatures exceeding 65.5°C for prolonged periods is not recommended.

 

Job Preparation: Drilled holes should be vacuumed and flushed with water. Sediment may cause blockages. Wider cracks may have to be sealed on the surface using Chem-Versatile. For stabilization applications, consult our technical department.

 

Cleaning: remove uncured Chem-Crete Terra Foam CCC528 from tools and equipment with a suitable solvent such as Xylene. Toluene or Blended solvents immediately after use. Cured material may only be removed mechanically.

STORAGE

Chem-Crete Terra Foam CCC528 is sensitive to moisture and to high storage temperatures. We recommend storage at 5°C to 15°C under dry conditions. Storage temperature should not exceed 27°C.

SAFETY

After hardening thoroughly, Chem-Crete Terra Foam CCC528 is physiologically harmless.

 

Keep the resin and hardener away from the eyes mouth and skin.  Do not breathe in the vapors.  The uncured mixture can cause irritation of the skin.  For best protection, wear rubber or plastic gloves.  In case of contamination, wipe away resin or hardener immediately from the skin using paper towels and then wash with soap and water or hand cleaning detergent.
