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.

FastSlab enabled us to replace a large badly rotten ground floor with a very lightweight but durable system very quickly.

Ben Biker

The lightweight nature of the beams makes installation very simple and quick. No heavy lifting equipment is needed and it can be done in most cases by one person. The EPS insulation blocks are light but strong allowing foot traffic, therefore providing a working deck while the Lewis Deck is being laid on top.

FAQs

Ask CDI a Question

  • Q

    What are the Lewis Deck sheet sizes?

    A

    Q: What sheet sizes are held in stock for delivery within a few days after order? A: We stock 2500mm and 1300mm sheets.  These are all 630mm wide and 16mm deep.  Deliveries are made via the pallet network directly to site.  The smaller sheets are aimed at small bathroom renovation projects and can be supplied in small numbers via TNT. 2.5* and 1.3m sheets allow for the 100mm overlap to occur over a joist, with joist centres being either 300mm, 400mm, 600mm, 800mm*, 1200mm and 2400mm*. (*2.5m sheet only) For larger projects we are able to produce bespoke sheet sizes if required, please get in contact to discuss other options for sheet sizes.

    Q

    Lacomet – How come it has no scrap value?

    A

    Lacomet – How come it has no scrap value? Many of the projects that we get involved in starts with a phone call or email to us from someone researching replacing stolen leadwork. Many of these are old buildings, such as schools or churches, where this isn’t the first time that the lead has been stolen and they call us fed up with having to replace it again full in the knowledge that they will more than likely go through the same problem once more in the near future if they continue to use lead. One of the big benefits that Lacomet FL brings to a project is the fact that it has no scrap value and therefore the chances of it being stolen are massively reduced. Due to the 2 thin aluminium layers, and its five layer total construction, it is of no value to thieves. Lacomet can be recycled but the polyester based coating would need to be de-laminated first and the amount of recovered aluminum is then very low, in fact it would be easier and more profitable to collect empty drinks cans than to mess about stripping Lacomet down. We can also supply stickers that can be placed in strategic locations informing people that what is now on the roof is not lead and that it has no scrap value.

  • Q

    Why don't my Lewis sheets interlock like they do in the video?

    A

    Q: Why don't my sheets interlock like they do in the video? A: The sheets have two sides (one printed, one plain), the dovetails on either side are different widths, it is then necessary to alternate the sheets print up and then print down.

    Q

    Is this a question?

    If it is, this is an answer.
