Polyethylene-polypropylene composite waterproof membrane is mainly made of polypropylene non-woven fabric and polyethylene as the main raw materials, and a four-layer sheet with an enhanced protective layer, an anti-aging layer, a waterproof layer and a tackified reinforced layer is manufactured by adding additives to improve performance The shape material is an integrated composite waterproof material.

1. The product is composed of different materials, the performance of the product has been significantly improved, especially the product is provided with an anti-aging layer, which greatly improves the service life of the product and can reach more than 50 years.
2. The upper and lower surfaces of the product are rough, and the non-woven fabric fibers have an irregular cross structure to form a three-dimensional mesh, which makes it have high tensile strength, strong impermeability, good low temperature flexibility, small expansion coefficient, low temperature opening effect, and deformation Strong adaptability, large friction coefficient, can be used with a variety of adhesives, and the bonding effect is good.
3. When the product is bonded to the cement base surface, cement paste can be used as the adhesive. The cement paste can directly enter the mesh on the surface of the coiled material. As the cement solidifies, the cement paste does not age and needs to be changed. , Hydrolysis and other problems, so the bond is permanently strong and should not be peeled off.
4. The surface of the waterproof layer after construction with this product can be directly decorated and decorated (such as pasting ceramic tiles, floor tiles, mosaics, mortar, etc.). *The construction of this product has no special requirements for the moisture content of the leveling layer (base layer), as long as there is no water, the construction can be performed, and the construction quality is reliable.
5. This product is a resin polyethylene series polymer waterproof membrane, which is a non-toxic and non-polluting green environmental protection product.

Suitable for waterproofing of various roofs, basements, tunnels, and other buildings; roofing and underground engineering of civil and industrial buildings, reservoirs, municipalities, bridges, subways, tunnels, dams, and other projects, especially for durability and corrosion resistance Key projects that require high performance and are easily deformed.

1. Construction procedure: acceptance of leveling layer-cleaning of base layer-preparation of cement binder-additional layer-base layer construction-protection layer-maintenance
2. Before bonding, pre-lay out the roll material, straighten it, and then roll up the two ends of the roll material, pour the prepared cement adhesive onto the base layer, and scrape it evenly with a scraper. The roll material is pushed forward, and the air left in the roll material is removed with a scraper in time, and excess adhesive is scraped out. The bonding rate of coiled material and leveling layer 2 85%
3. Seam practice:
1. Construction of roof waterproof joints: The vapor barrier, waterproof layer and additional layer are all lap joints, cemented with cement adhesive, and the width is 10cm. The joint of the additional layer and the waterproof layer are staggered by more than 5cm.
2. Construction of waterproof joints in basement: 10-15cm overlapping joints of cover strips are adopted, and the cover strips are bonded with polymer joint adhesive.
3. The overlapping width of the waterproof membrane is 8-10cm on the long side and 10-15cm on the short side. The adjacent short side joints should be staggered by more than 100cm. The angle between the wall and the ground is more than 30cm.
4. Protective layer: After the roll material is glued, a 1:2.5 cement mortar protective layer with a thickness of 2cm needs to be formed on the waterproof layer, which is smeared twice. The second layer must be staggered by more than 20cm. The protective layer needs to be smooth and watered Conservation.
When the high molecular polyethylene polypropylene (polyester) waterproof membrane is bonded to the main body of the structure, a special cement material is used as an adhesive.
Construction application one
Roof waterproofing: Special attention should be paid to the bonding area and bonding strength of the coiled material and the leveling layer. This is the key technology to ensure the waterproof effect and waterproof life. Underground waterproofing: The coiled material should be designed to be used under water-backed conditions to prevent peeling. In the absence of backing, the peel strength of the coil should be calculated.
Indoor anti-seepage: When applied to the anti-seepage of internal walls including floors, after the coiled material is pasted, the bonding layer should be hardened before surface decoration construction. Before decorating the surface of the interior wall, a layer of 1.5% should be applied to the coil
Polypropylene (polyester) composite waterproof membrane supporting cement paste with special rubber powder.
Ground moisture-proof: applied to the ground moisture-proof, pay attention to the thickness of the ground surface layer to ensure the stability of the ground. The vertical height of the coiled material at the foot of the wall is not less than 200mm.
Insulation and gas insulation: single-layer composite coiled material can be used for steam insulation of the insulation layer. Its pasting and laying are the same as roof waterproofing. The joint adopts double-sided composite coiled material and no protective layer.
Construction Application 2
Seepage prevention of channels and reservoirs; seepage prevention of earth-rock dams
Other applications
It can be used in metallurgy, chemical anti-pollution, anti-seepage, pipeline waterproofing, mine waterproofing, road and bridge waterproofing, tunnel waterproofing and other uses.
