Product Overview Froouct Introduction:
The product is a waterproof membrane made of strong cross membrane as the surface layer or tire-based reinforcement layer, double-sided coated with reactive modified asphalt self-adhesive, and covered with an insulating material. The product adds unique activators, water immersion agents, etc. to the self-adhesive adhesive, on the basis of maintaining the advantages of traditional self-adhesive rubber, increases the creep of the glue, so that it penetrates into the pores and capillaries of the concrete, forming physical adsorption and mortise action, and at the same time, the concrete and cement gel have a chemical reaction to form a chemical cross-linking structure, so that the membrane and the base layer are firmly bonded, forming a closed and sealed waterproof layer.

Product Features:
●The self-adhesive layer reacts synchronously with cement gel or cast-in-place concrete and forms a layer of viscous coating that is firmly bonded to the base surface, effectively eliminating the phenomenon of water channeling, and at the same time, the viscous coating and self-adhesive membrane form a high-performance composite waterproof fortification;
●Cross film is a special 45° diagonally cut polyethylene film, its vertical and horizontal tensile force and elongation reach the balance golden point; The cross film has high strength, is not easy to tear, and has high puncture resistance;
●It has creep and strong adaptability to the deformation of the base layer, which can meet the construction of a variety of environmental conditions and can play a good "self-healing" function. Only the lack of rigid waterproofing can make up for the lack of rigid waterproofing of concrete, and achieve the dual waterproof effect of rigidity and softness. Good thermal stability: under ultraviolet rays, the size change rate is small, and it is not easy to wrinkle; The construction is simple and convenient, which is conducive to ensuring the construction period and quality.
Scope of Application:
It is suitable for waterproof projects such as basements, non-exposed roofs, and municipalities
Construction method:
Pasting method: On the dry, flat, dust-free base layer, first apply the base layer treatment agent, after drying, remove the self-adhesive surface separator film, and directly bond it with the base layer.
Wet laying method: the cement slurry is evenly applied to the base layer, which is used for the bonding transition between the base layer and the self-adhesive surface of the coil, and after removing the separation film of the self-adhesive surface, it is used to transition
The adhesive layer is directly bonded. During façade construction, a certain amount of special glue can be added to the cement slurry to increase the viscosity of the cement slurry.
Process flow: base layer cleaning→ moistening base layer→ positioning, elastic line→ applying cement slurry→ paving self-adhesive waterproof membrane→ patting the upper surface of the membrane, slurry→ drying
Put it in 24h to 48h→ the coil is closed, sealed→ trimmed, and accepted.
Operation points: ●Base layer treatment: The surface should be treated first to make the base layer solid, clean, and fully moist, without water accumulation.
Weight ratio of prepared plain cement slurry: 42.5 Cement: water = 2:1, the amount of water added can be adjusted appropriately according to the base surface and climatic conditions, the cement is soaked to remove the thin floating slurry on the surface, and then stirred evenly with an electric motor.
Plain cement slurry: According to the flatness of the base layer on site, determine the thickness of the cement slurry, usually about 3mm, and pay attention to compaction and smoothing when spreading. The scope should not be too large when applying cement slurry, and it should be laid while plastering.
The paving coil should discharge the air from the lower surface of the membrane, so that the membrane and cement mortar are tightly bonded. The lap width of the coil should not be less than 80mm.
Executive Standard:
The physical and mechanical properties comply with the requirements of Class E in GB/T35467-2017 "Wet Paving Waterproof Membrane";
