Detailed introduction to PVC Waterproof Membrane:
CPS Polymer Self-adhesive Waterproof Membrane
Introduction
CPS Polymer Self-adhesive Waterproof Membrane is a kind of synthetic polymer waterproof membrane which made from polymer self-adhesive polymer, uses Polymer sheet(PE, EVA, ECB, PVC) as the original source. It has high tensile strength, perfect elongation, excellent resistance to punture and tear, the greatest feature the material is: Concrete can be pasted directly on the membrane surface, after the concrete has been setted, bond strength of membrane and concrete is greater than 2.0Mpa so as to solve the problem of membrane channeling water and leakage.
Features
1.High Tensile strength, excellent resistance to tear and puncture.
2.Strong adhesion with the concrete, effectively prevent the emergence of a single polymer sheet phenomenon of channeling water.
3.Lap with pre- self-adhesive side lap to ensure the seamless of waterproof system.
4.Perfect resistance to acid&alkali,weather and aging.
5.Simple operation, High work efficiency, Low cost.
6.Non toxic, tasteless and be environmentfriendly.
Scope of Application
Large-scale underground structures.Surface of concrete slabs for planting.For Roads, Rails, Subway tunnels projects.For reservoirs, canals, dams and other water conservancy projects.For air defense, military facilities waterproof projects.Technical capacity
Ref to Chinese Standard: JC898-2002
Construction technology
Tunnels, bridges should use polmer sheet welding lap joints. Firstly, pre-paved polymer sheet side of polymer self-adhesive composite waterproof membrane toward the base, and fix it with dedicated pieces of machine, double lap weld seam welding machine should be used for lap joints. Tear off insulation paper, band reinforced concrete directly, self-adhesive waterproof membrane will adhere to the main body of concrete structure closely to achieve full adhesion.General building underground projects should use self-adhesive overlap method. Basement bottom: pre-laying the membrane on cushion firstly(polymer sheet face down), tear off reserved isolation paper of lap joints self-adhesive side and can be sealed when paste directly; tear off isolation paper of self-adhesive waterproof layer, structural concrete, the membrane will anti-stick to the concrete structure to form dense waterproof system.Basement side wall, Surface of concrete slabs for planting: attach the self-adhesive material side to the base surface directly, tear off reserved isolation paper of lap joints self-adhesive side. Side wall shall be fixed with dedicated pieces of machine.Half header treatment:Wether horizontal half header or vertical half header, which should be sealed with sealant, membrane in the elevation without groove half header, it shall be fixed with metal straps firstly, then seal the top hole of metal straps and fixed screw with sealant.
Cautions
Do not put the membrane on a pollution, water and ice ground.Construcion of waterproof layer operations can't be crossed, device shall be installed on the waterproof layer, parts should be done to strengthen the basis of device and to take protective measures.Do not touch the waterproof layer with thorn sharp objects after it's has been completed, don't put sundries or any additional buildings above the waterproof layer to avoid damaging it.
