Special TPO Self-adhesive Waterproof Membrane for Roof of Aegis Technology Pipe Gallery
Aegis thermoplastic polyolefin self-adhesive (TPO) waterproofing membrane adopts an integrated production process, which is produced by copolymerization of ethylene, propylene and butylene. Self-adhesive TPO waterproofing membrane is formed by coating self-adhesive layer and PET protective film behind the polymer sheet.
Pre-paved anti-adhesive TPO waterproofing membrane is for the convenience of construction. An anti-adhesive coating is added to the self-adhesive layer. After the PET protective film is removed during the on-site construction, the adhesive layer does not stick to the feet and will not affect the construction of workers at other civil engineering levels.
In the past underground engineering, reinforced concrete structure and flexible waterproof layer can not be closely bonded, leakage water in the waterproof layer and the structure between the horizontal flow, from the concrete gap leakage (commonly known as "water"). The pre-paving anti-sticking method can effectively limit the expansion of the damage point, prevent the diffusion and channeling of leakage water, and reduce the risk of leakage. And TPO waterproofing membrane lap edges are all hot air welding, high joint strength, welding is the most reliable way of all waterproofing membrane seams, can effectively ensure the waterproof effect.
In addition to planning and construction in advance in the process of urban development, the underground comprehensive pipe corridor is more often located under the main roads of cities with busy traffic, such as the urban core area and the central business district. In the case of high road traffic pressure, the construction period is often very tight. After the floor cushion layer in TPO pipe gallery waterproofing system reaches the strength that can be used, the anti-adhesive TPO waterproofing membrane can be directly paved over the cushion layer. The side wall and roof adopt 2mm thick PMC coating waterproof layer. Waterproof mortar can be constructed when the base layer is wet and free of open water. Self-adhesive TPO tears off the isolation membrane and uses its own adhesive layer to bond to the base layer. The construction is fast and is conducive to ensuring the construction period.
Waterproof mortar to repair the defects of concrete at the grass-roots level, at the same time, it can form a complete waterproof layer, improve the adhesion of self-adhesive TPO waterproofing membrane and the grass-roots level, avoid the phenomenon of "water channeling", and ensure the waterproof effect of double fortification.
Therefore, the TPO underground pipe gallery waterproofing system not only depends on the "Yan value" to win, but also has the inherent "hard power". With excellent physical properties of the membrane, construction speed, waterproof effect of reliable construction technology, TPO waterproof membrane for the hundred years of pipe corridor project escort.
