Polyfleece SX 1000
POLYFLEECE SX 1000 from StekoX is a swellable, waterproofing fleece that can be used on existing buildings as well as with fresh concrete in new buildings. All concrete surfaces that are in contact with the ground in any above or below ground civil engineering construction can be permanently and reliably waterproofed with the fleece. The fleece is installed either in strip form or as a fully covering external seal on to the reinforced concrete constructions. One side of the fleece features a swellable, modified polymer coating which with a swelling rate of 150 per cent ensures a particularly effective seal. In order to waterproof existing structures, Polyfleece SX 1000 is bonded directly to the structure with the coated side facing towards the concrete surface. For this procedure, a low viscosity sealing compound that has been especially developed for Polyfleece SX 1000 is also used. Before applying the sealant, the surface in question is to be cleaned to ensure that it is firm and free of any loose matter which will then guarantee the sealant providing the best possible adhesive joint. Between the concrete surface and the fleece, swelling pressure triggered by moisture is built up which effectively seals any cracks that may appear in the fleece's coating caused for instance when filling in with earth. The Polyfleece SX 1000 coating has a thickness of 1.4 g/cm
and can withstand temperatures of minus 40 to 100 degrees Celsius or even more than that.
