Expansion resin

For all URETEK expansion resins, the mechanical properties increase in line with the increase in the density of the expanded material. The density of our material is highly dependent on the resistance it encounters during expansion.

URETEK expansion resins are FCWK- and formaldehyde-free. They also contain no radon. No permit is therefore required to apply the URETEK method. The Dutch authorities have such confidence in our method and the materials used that we have even been permitted to carry out projects in sensitive nature reserves.

Laboratory tests show that our expansion resins can withstand prolonged exposure to most substances without significant damage. URETEK expansion resin contains no formaldehyde or radon.

URETEK has commissioned various studies by official research institutes in the fields of the environment, engineering, sustainability and the performance of the expanding resin. For further information about these studies, please contact our technical advisers.

The applicability of our injection techniques is closely linked to the nature and composition of the soil in question, particularly in relation to foundations. Based on our current understanding and the state of the art, there are a number of limitations.
