Heat Welding Pvc Membrane
After the felt lining is in place the pvc membrane which typically comes in 1 8 m 6 ft wide rolls is rolled out and positioned within the pool.
Heat welding pvc membrane. One of the key benefits of thermoplastic membranes is the ability to heat weld their seams and create a permanent seal. A handheld heat welder and roller are used to make the repair see fig. Tpo is thermoplastic so you can heat weld seams and it s ideal for repairs. Once the pieces have been measured cut and positioned a tack weld or pre weld is used to keep the material in place.
This ensures superior seam strength and makes the membrane resistant to leaks and wind blow off. Epdm cannot be welded and cannot be re taped when the weather is too cold to use primer and adhesives requiring a temporary fix until the weather warms up. This hot air welder lst wp1 is of advanced heating function it is powerful stable and easy to be operated which is suitable for pvc tpo cpe and other polymer waterproofing membrane roof constructions. Regardless of what installation procedure is chosen all pvc roofing systems are sealed with a hot air welder.
Position the automatic hot air welding machine with the pressure wheel approximately 3mm over the weld edge to ensure a sealed edge. Simply clean the membrane and heat weld directly to it. Immediately begin moving the machine along the lap to prevent scorching of the membrane. If patches are attempted the bottom unexposed side of the membrane will be more receptive to welding.
The material is basically tailored to the pool on site. A pvc roofing membrane can be installed in three different ways. For cuts or tie ins of new equipment a patch can be inserted under the existing membrane and a few inches wider than the hole. Lift the overlapping membrane sheet and insert the blower nozzle between the overlap.
