MAXURETHANE® FOAM
TWO-COMPONENT POLYURETHANE RESIN SYSTEM FOR SOIL INJECTION AND CONSOLIDATION

Description

MAXURETHANE FOAM is a two component, CFC free product.
A component is a polyisocianate MDI type and B component is a pre-formulated polyol.
When injected with the proper equipment at 1:1 mixing ratio, their reaction will provide a foam as a result which fills cavities and hollows in the ground.

Uses

- Filling of any spaces or hollows behind below grade structures (tunnels, metros, underground car parks)
- Injection of anchoring
- Injection of joints in channels, water main, etc

Application

The injection will be performed by means of a two component type pump with a volumetric ratio of 1:1 installing a static mixer in its end. The injection will be performed directly on the ground or the joint to be sealed.

Advantages

- Low viscosity ensures good and deep penetration
- High fluidity
- CFC free
