Expander mortar – Expander concrete

We are specialists in expander mortar/expander concrete and undercasting mortar adapted for, among other things, advanced undercastings that require easily pumped, shrink-free materials with high strength. As the name “expander mortar” suggests, the products expand before they harden.

Our expanded concrete is mainly used for advanced undercasting of columns, crane tracks and bridge bearings. Expanded concrete has high strength and expands, unlike ordinary mortar, which shrinks when the water evaporates.
