EVA polymer pre-shop-adhesive waterproof membrane Product Overview: pre-shop is the use of self-adhesive waterproofing membrane after pouring concrete or cement mortar version of the self-adhesive and non-adhesive waterproofing membrane. Product Features: 1. Pre-shop directly with self-adhesive membrane structure after pouring concrete mixture bonded directly. (2) Excellent adhesion sheet, filled with the structure to achieve full bonding, to effectively prevent damage occurs channeling water phenomenon. 3 simple construction, cold construction, safety and environmental protection. Category: Construction methods topic subject material bonding surface membrane material thickness pre-shop full thickness (Y) waterproofing sided adhesive double-sided adhesive 0.7mm 1.2mm 0.2mm 1.7mm 1.5mm 2.0mm Standard: GB/23457-2009 pre-shop the physical and mechanical properties of a waterproofing membrane Item Index 2 Rally (N/50mm) ≥ 500 3 film elongation at break,% ≥ 400 4 shank tear strength / N ≥ 400 5 Heat resistance 70 ℃ for 2h, no sliding, flowing, dripping 6 Cold bending temperature ≤ -25 ℃, no crack 7 Impact diameter (10 ± 0.1) mm, no leakage eight static load 20kg, no leakage nine and after pouring concrete Peel strength (N / mm) ≥ 1.5 10 Thermal Stability appearance without wrinkling, sliding, flowing dimensional changes /% ≤ 2.0 polymer adhesive film (pre-shop) a waterproof membrane construction technology, clean base surface: Clear Concrete the base surface of dust, debris. 2, Omo construction waterproofing membrane developed by the shape of the base surface membrane paving the order will roll tile or fixed on the base plane. Long side lap sheet is not less than 70mm, the short side lap is not less than 80mm. Spread to parts of the pile head node, the coil just laid up to the trailer coupling root negative angle can be, without turning to the pile head on the side. 3, the pile around the root real shop or fixed coil: coil in a large area of ??empty shops, the pile around the root requirement mechanically fixed MAC membrane. The real shop web site just outside the arc roots paving to the pile of parts, negative angle, then part of the column root pile brushing two capillary crystalline waterproofing coating. 4, waterproof layer inspection can be carried out after completion of construction work can be carried out after acceptance after the process of construction. 5, Attention: 1) waterproofing membrane with cold-construction, welded steel produced if Mars, the membrane surface to be welded at the temporary protective measures. 2) Coil laying is completed, should pay attention to the follow-up protection, reinforcement cage must be based on the principle of light put, you can not drag on the waterproof layer, waterproof layer to avoid damage. Yer isolation membrane, in order to avoid the adhesive surface is contaminated, you can sprinkle a layer of cement powder in isolation. 3) between two adjacent rows of the short side of coil joints should be staggered 300mm or more, in order to avoid duplication and makes multi-joint web paste uneven service. 4) Stones roll procedure: first node after the Omo; first distance, after the vicinity. After that all nodes paving, paving Omo membrane only; Omo Shop sticky membrane must first do far, after doing nearer, the operator has completed but more stampede membrane. Construction area should take necessary measures to striking envelope (around providing the necessary channels), prohibit walking trampled.
