Support for steps made of cobblestones, slabs and blocks. 

Our TERRA range provides unrivalled protection against ground frost thanks to its exceptional dimensional stability, reducing ground movement in freeze-thaw cycles for lasting strength. The unique permeability of our substrates preserves the integrity of the concrete while preventing the formation of deep-seated ice.

As a soil-infill solution, they simplify construction by halving excavation depths and the amount of stone backfill required, speeding up paver installation. Our insulation remains the optimal choice for efficient, durable and economical projects.
