Heave Stopper


Heave Stopper


Unlike other solutions Heave Stopper creates a complete void beneath the foundation to offer maximum protection from ground movement.

Heave Stopper is a board constructed from a cardboard honeycomb core set between water resistant facings. When dry, the boards have a compressive strength that can support concrete and steel up to 1 meter thick without deflection or creep compression.

Eventually, the board will naturally disappear to leave a permanent 100% void with no residual density to pass on heave stresses.

Size: 2400mm x 1200mm x the required thickness
