Creating a wet-room in either a new-build or renovation situation on the 1st floor is often complicated by the presence of timber floors that move and flex and therefore end up with expensive leaks.

Our systems are primarily floor strengthening and reinforcing systems that also allow the incorporation of wet room drains directly into the floor.  This then gives the same concrete feel to the whole of the floor and because of the stiffness of the systems, they allow the use of large format tiles of any type including ceramic, marble, porcelain or stone.

As these are also underfloor heating solutions, they allow wet underfloor heating pipes to be installed and you therefore get a warm floor with the same or better performance as a concrete or screed ground floor.

The use of a concrete screed allows the falls to be built into the floor for drainage and retains the same feel across the whole of the floor.

This principal can also be used externally for balconies and terraces with integral drainage within the floor deck, this allows the use of concealed drainage options.

The Lewis system works very well with screeded underfloor heating and cooling systems, allowing them to work more efficiently than without the sheets in place. LEWIS provides a number of solutions …

  • 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?

    A

    If it is, this is an answer.
