Physical Properties

Compressive Strength: More Than Satisfactory.

The most significant physical property of Uretek injected material is its compressive strength, which is more than satisfactory for its typical applications.

Within certain limits the URETEK polymer demonstrates elastic characteristics. Hooke’s Law states that compression is proportional to applied forces and will not exceed more than 10% in deviation.

Only when force exceeds the elastic limit is the internal cellular structure permanently modified. The elastic limit depends on the density of the material.

The URETEK polymer is primarily used to consolidate ground and to relevel settled structures.

So from a practical point of view, the most important property is compressive strength.

The diagrams indicate the effect of density on the resistance to compression of typical Uretek resins.

The usual surface density of the URETEK material, which is about 70kg/m³ when injected beneath flooring, can reach more than four times that figure in Deep Injection levels.

SUMMARY: The compressive strength of injected Uretek materials is more than satisfactory for the usage applications outlined in this website.
