US Foam and Grout

The two-component resin is delivered by a pump unit and injected in a ratio of 1:1 by volume through a mixing gun. The resulting medium sets to produce an elastic non-foaming mass with outstanding adhesive and compressive strength.

US Foam

When injected into the strata, the medium flows into the cracks and fissures and rigidifies, thereby creating an elastic bond that is capable of retaining its integrity even after rock movement has occurred. US Foam remains unaffected by water, therefore it will always expand to completely fill any
void without compromising strength and expansion ability.

In addition, US Foam is fire-resistant. The expansion ratio of US Foam is approximately 30:1. Its low exothermic reaction allows large cavities to be filled completely in one pumping session without overheating. 

US Foam is a two-component grout that comprises a silicate and a modified polyisocyanate intended for:

• Strata consolidation
• Coal face reinforcement
• Large or small cavity filling
• Water control

US Grout

When injected into the strata, the medium flows into the cracks and fissures and rigidifies, thereby creating an elastic bond that is capable of retaining its integrity even after rock movement has occurred. US Grout remains unaffected by water, is non-foaming and can even adhere to damp surfaces. In addition, US Grout is fire-resistant.

• Strata consolidation
