POLIMERO: GT - 402®

Home /Polymers / GT – 402®

GreenTechnologies®

GreenTechnologies® has developed a two-component polymer called GT-402® which, when fused into a patented chamber, creates a 4 lb/ft3 expansive foam without confinement conditions that is hydro-insensitive, high-density, and specifically designed for use in places where water or moisture is present.

This expansive polymer can be used for residential, commercial and/or industrial applications. It has a high content of recycled material which is a contribution to improving the environment.

Uses of GT-420 Polymer

Soil stabilization.

Deep injection.

Releveling of concrete floors and structures.

Void filling.

Support for breakwaters.

Increase in the load-bearing capacity of the soil.

Expands up to 18 times.
