Ground heave solution Pecavoid®

Combat the Effects of Ground Heave on Foundations and Slabs

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.
