Most roofs are built-to-falls for drainage purposes. Where the level between the door threshold and the drainage outlet is significant, where the roof falls in more than one direction, where large drops or channels are present, or where there are multiple and complicated changes in the fall and levels across the roof – then the ASP range of Adjustable Support Pedestals are the perfect tools.
This is a suspended system – the weight of the slab holds everything in place.
Wallbarn’s ASP adjustable support pads are designed with a telescopic stem which is wound up and down to achieve a completely flat upper paving surface. Changes to height can be made whilst the slab is in place. This saves a great deal of time and labour.
The rainwater runs between and under the slabs, so there is no standing water left on the surface. This improves health & safety as it makes the paved area less slippery.
