Ground heave solution Pecavoid^®

Ground heave is primarily caused by the rehydration of clay or expansive shale soils, overburden recovery resulting from deep excavations, mining or trees and vegetation.

MAX FRANK’s Pecavoid^® is a proven and effective solution to combat the effects of ground heave on foundations and slabs. Pecavoid^® acts as a protective layer, between the soffit of the suspended foundation and the expanding clay soil, and is designed to compress when ground heave takes place.

Pecavoid^®, and its associated ground heave products, can be supplied in a number of grades and depths – designed to provide full foundation protection, in any type of expanding soil situation, during the complete life span of the building.

Since its launch in 2011, Pecavoid^® has been successfully installed on major projects including; airports, schools and colleges, retail and large-scale residential developments. Manufactured from interlocking sections of expanded polystyrene, it is lightweight and easy to install.
