In 2010, Finnfoam introduced a footing mould solution that makes construction work easier. The cost-effective and easily implemented solution utilises Finnfoam's excellent strength characteristics.
Today, ground frost insulation is also often installed beneath the footing of the building. In passive and zero-energy houses, ground frost insulation should always be installed under the footing to break the cold bridge. In non-heated buildings and open-walled shelters, a sufficiently wide thermal insulation is always required under the footing. The recommended width is 2 to 5 metres.
Installing the insulation and preparing the mould for pouring the footing can now be completed in a single step. The Finnfoam footing mould makes pouring the footing quick and uncomplicated. Finnfoam is very strong and durable – an ideal material to be used under the footing.
Footing mould boards are pre-shaped with pre-marked break points for breaking off the vertical sides of the mould. The vertical sides are snapped off at the construction site. The vertical side elements are then depressed into the groove in the board, forming a solid footing mould. The vertical sides attach to the base board so that each of them also keeps two base boards together.
The mould is reinforced at the construction site. For horizontal reinforcement irons, installation grooves are sawn on the vertical sides using a chainsaw. The vertical reinforcement structure is supported by the horizontal reinforcement bars. The horizontal reinforcement also supports the vertical sides of the mould. The horizontal reinforcement irons must be bent to the shape of the letter U with a distance of 740 mm between the prongs. The concrete is poured normally. The U-shaped horizontal irons may also be made of stainless steel if required by dimensioning specifications.

The storage dimensions of the footing mould are 600 × 200 mm (inside), insulation thickness is 70 mm and strength grade is F-400. The mould is used to lay a well-insulated footing and a form casting mould where the reinforcement bars of the vertical side form the support structure for the horizontal reinforcement.
