Benefits of Clayboard
The Advantages of Clayboard®
Apart from the immediate advantages of a slimmer product
requiring less soil removal and therefore reduced 'muck away' costs
and Landfill Tax, Clayboard® has other specific advantages over
other methods of clay heave protection.
Industrial and Commercial Buildings
Traditional clay heave systems can exert considerable pressure
on ground slabs during the compression process. Clayboard® is
unique, with its central core designed to collapse under just
3Kn/m2 once water has been introduced.
Residential Buildings
Some types of clay heave systems are unsuitable for housing as
the pressure exerted far exceeds the load on ground slabs.
Clayboard® falls comfortably within this limit and provides an
economical alternative to block and beam void creation systems.
Clayboard is recognised by the NHBC as an appropriate void
former for residential properties, so builders can be confident of
the product's suitability.
Clayboard® Certifications

ground slabs in all types of residential, commercial and industrial
