Proform is an authorized manufacturer of StoneTerra Retaining Wall Systems in the province of Alberta. The attractive natural quarried rock is easily placed using small equipment, for a sensible per square foot cost.

These structural retaining walls are easily constructed using gravity or engineered inter-locking precast concrete blocks.  Gravity walls rely on mass to resist the forces produced by pressures behind the wall. As wall height increases, there is a need for increased mass. StoneTerra offers blocks in various weights and depths that allow walls to be tailored to resist associated pressures and loads.
