Durisol Blocks

Durisol ICF blocks (R-12) are made of cement mixed with recycled wood fibres. The hollow blocks are used for building and have a cement mix poured into them. The cement can include slag or fly ash as a filter.

How does it work?

Durisol blocks are made from a proprietary cement-bonded wood fiber material that has only natural ingredients. It is composed of specially graded recycled waste wood (100% clean, natural softwood lumber). This wood is first chipped into wood fibre. It is then mineralised and bonded together with Portland cement. This Durisol material is then moulded into the cement-bonded wood fibre reinforced ICF concrete forms.
