immediate consultationDetailed description
Product Introduction
The Zhuozhongzhizhong brand ZZW-302 polymer self-adhesive waterproof membrane is made of polymer sheets HDPE/EVA/TPO, strong self-adhesive materials, and isolation membranes (or fine sand) through a special composite process. It is a waterproof membrane (pre-laid reverse adhesion) that can form a strong bond with post-poured concrete structures.
Specification
Applicable Scope
Suitable for waterproofing of underground projects such as civil and industrial building basements, subways, tunnels, and pipe corridors.
Product Performance
1. The membrane has excellent waterproof performance, with good impermeability, high and low temperature resistance, and corrosion resistance. It can meet the requirements for level one waterproofing in underground waterproofing projects with single-layer use.
2. The polymer sheet used on the surface of the membrane has excellent puncture resistance and impact resistance. After the membrane construction is completed, there is no need to pour a protective layer, and subsequent construction processes such as rebar tying and concrete pouring can be carried out directly on the membrane.
3. The tensile and bending performance of the membrane far exceeds that of ordinary modified asphalt membranes, adapting to complex substrate deformations while maintaining the integrity of the waterproof layer.
4. The high-quality pressure-sensitive adhesive used in the membrane can create a very strong chemical and physical bond with post-poured concrete, forming an interface sealing layer that eliminates water channels between the membrane and the concrete main structure.
5. The pre-laid reverse adhesion construction method has relatively low requirements for the substrate, and there is no need to apply a substrate treatment agent. The adhesive side of the membrane is laid face up on the substrate, making construction convenient and quick.
Main Technical Index: GB/T 23457-2017
Construction Method
Precautions
1. The membrane should be stored in a dry, ventilated environment, and direct sunlight is prohibited.
2. Different categories and specifications of membranes should be stacked separately.
3. When the membrane is laid flat, the stacking height should not exceed three layers.
4. The storage temperature should not exceed 45℃.
