Note: In a totally dry state, the Product shrinks to its original dimensions. The product then expands again upon further contact with water.

Swelling pressure

The pressure developed by the material depends on the stiffness of the surrounding concrete structure, which is influenced by the concrete quality, voids, gaps and other weaknesses.

In an ideal concrete structure the material can develop a swelling pressure up to > 10 bar.
