Durisol ICF

The first ICF, Durisol, was developed in Belgium in 1937 by the Swiss nationals August Schnell and Alex Bosshard (following on from a Dutch patent registered in 1932.)

Initially manufactured in Austria, the Durisol product developed following the creation of a unique, natural treatment process that allowed raw wood fibre to be bonded with Portland cement. The original Durisol stay-in-place concrete wall formwork system serviced the building industry in post-war Europe, at a time when other natural resources were scarce and traditional building methods were not possible or cost effective.
