Product introduction:
HTC bearing Waterproof roll It is caused by small density Vinyl resin And fabric through automation production line Composite polymer waterproof coiled material formed by hot melt extrusion, composite calendering and traction rolling. It can withstand the normal tension, tangential shear force, lateral peel force and other physical and mechanical performance standards first issued by the state, It can not only be waterproof, but also bear all kinds of engineering answer The waterproof coiled material of Li has opened a new page for improving the quality of waterproof engineering and adapting to the needs of various projects.
Performance advantages of load-bearing waterproof membrane:
1. The concrete on both sides is firmly bonded together to form an integral waterproof structure;
2. The engineering stress can be transmitted between the concrete on both sides;
3. Direct bonding and installation on the base surface with high water content;
4. Direct polymer cement Firmly bonded to concrete;
5. Ensure that the waterproof works have the same durability and stability as the concrete;
6. Complete Eliminate the transverse permeable space between the concrete main body and the waterproof membrane, and realize the durable and stable waterproof function
Scope of use:
HTC Bearing waterproof coiled material can be widely used in basement, tunnel, lining, roof Tunnel, road and bridge And other waterproof works
Construction process:
1. The base course surface (leveling layer) for laying waterproof coiled materials must be cleaned, and the loose defect parts should be repaired smoothly;
2. The dry base course surface shall be watered to ensure that the base course is wet (the moisture content of the surface layer is preferably 30-50%);
3. Matching an adhesive Polymer adhesive materials shall be prepared and the thickness shall not be less than 1.3mm when paving;
4. When paving coiled materials, the facade shall be pasted first and then the plane shall be paved. The lap width of the long and short sides of coiled materials shall not be less than 100mm, and the short side joints shall be connected
It shall be staggered for more than 1m;
5. Additional layers shall be laid at corners, internal and external corners, pipe edges and floor drains;
6. The waterproof coiled material shall be paved in full, and the adhesive material shall be evenly brushed on the base surface without exposing the bottom, piling up, and brushing
Then the coiled material shall be paved immediately to prevent the bonding quality from being affected by too long time.
7. During paving, the air under the coiled material and excess adhesive material shall be removed from the edge of the coiled material to ensure that the coiled material, the base surface and each layer
The coiled materials are tightly bonded.
