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.
Maintains dimensional stability in wet locations.
Stopping water erosion in sewers.
Fields of application of GT-402® polymer
Airports.
Highways and roads.
Harbours.
Hydraulic works.
Railways.
Mines.
Historic buildings.
Residential buildings.
Commercial buildings.
