FIRMAFIL
As part of the general excavation and filling process, site excavated material is treated with lime as it is placed as fill, to give a FIRMAFIL specification of minimum 5% CBR.

FIRMABASE
FIRMAFIL can be retreated to a depth of 300 mm to a FIRMABASE specification of minimum 30% CBR to provide a sub base that only requires a nominal 100 mm stone topping to protect it from site traffic. The stone is left in place as part of the overall construction, and can be trimmed and topped with the final paving or slab material as required. On sites of a large area this can lead to a significant saving in imported stone.

FIRMAROC
Provides a superior construction layer capable of withstanding the most onerous of temporary conditions such as piling and steel erection. Firmaroc uses a layer of site won granular material such as demolition waste or imported stone, which is cement stabilised to provide a highly superior CBR of 100-150%. It is highly durable under severe weather conditions.
