The FastSlab Ground Floor system is designed to make it quick and easy to replace existing suspended ground floors with an insulated concrete or screeded floor. This gives the solid feel of a concrete ground floor with the benefit of maintaining the ventilated void beneath to prevent moisture issues in the existing walls.

The FastSlab system is a unique combination of the Dutch VBI PS ground floor renovation system and the Lewis Deck metal dovetailed sheet.

The PS renovation floor system is a patented innovation from VBI and is a lightweight altrenative to block and beam floors. The unique feature of the “FastSlab” system is the use of galvanised steel joists that weigh only a fraction of pre-cast concrete beams. Joists are supplied in standard lengths and can be very easily cut on site. The tight fitting EPS insulation blocks are available in 2 thermal performance values (0.23 W/m2K and 0.20 W/m2K) and sit between the galvanised beams creating a robust and thermally efficient sub floor ready to accept the finished slab.

Both the beams and the infill blocks are light and easy to handle making the installation in renovation and conversion projects, as well as new build, so much easier than if using concrete beam and block.

The use of Lewis Deck on top of the PS system removes the need for a reinforced concrete slab needing to be added to the system. This reduces the overall depth of the screed to 50mm as well as reducing the weight without compromising the load bearing capability. It also allows the addition of a very efficient underfloor heating system within the floor zone.
