Good Quality Membrane Waterproof Eptfe Breathable Waterproof Sheet Film Film

EPDM waterproof coil is mainly composed of ethylene—propylene—butadiene terpolymer synthetic single layer cure type rubber macromolecule homogeneous sheet. It owes complete saturation molecular chain and the molecular structure is stable, its excellent physical performance remain unchanged for long, convenient installation and maintenance turn it into one of the most mature and most widely used waterproof material. 

1. Excellent weather resistance, aging resistance, oxidation resistance and long service life
2. With high elasticity, high strength, high and low temperature resistance and excellent physical properties.
3. Perfect anti-crack performance, strong adaptability to contraction and cracking of basic level. 
4. A complete series of matching products , fast and convenient installation and maintenance.
5. Offers a variety of width and thickness of the material according to engineering demand.

Technical Data

Scope of Application :
Widely used in all kinds of building roof, pond, underground waterproof and special requirements of the waterproof engineering.
Construction technique:
1. Basic Level requirements: the surface of the waterproof level should be tightness, level, clean and dry( water ratio≤7%) , any flaw must be repaired to meet the need of designing and spreading the material.
2. Construction methods: According to engineering requirement, it can be taken full spread method, bar spread method, point spread method or empty spread method.
3. Coating Polyurethane base layer on the base level before spread sheet material laying, After dryness, the first step is to strengthen the detail node additional layer with polyurethane coating or sheet, then to complete the construction in large areas.
4. After coated glue on the sheet material and the basic level, cold them to not adhere to hand, EPDM Can be spreaded and adhibited, and timely roller pressure, exhaust
5. Clean and clear the interface part, then Use interface glue or butyl adhesive tape for bonding.
6. The Interfacial gap and the position of the head with polyurethane sealant or butyl adhesive tape sealing, width not less than 10 mm
7. Attention:
a. In any circumstances like rain, snow, fog, more than 4 grade gale days and the basic surface is damp, the construction work is not allowed.
b. Supporting materials: Adhesive glue, diluents, polyurethane coating should be occasional with take, use up timely closed, avoid wasting and pay attention to fire.

Administer Standard:
GB18173.1-2000Polymer Waterproof Material Part 1 Sheet.
Storage:
Sheet in the transport and storage, should pay attention to keep packing full, placed in ventilated and dry place, storage pile high should not be more than keep flat five coils height. Pile up, should liner flat board, from the ground 20 cm, and should avoid direct sunlight and banned and acid, alkali, oil, organic solvent contact, and isolating heat source.
According to the recommended storage way under the condition of original packaging from the date of production guarantee period of 12 months.
Package:
Hard paper core crimp packaging 24 square meters / roll.

LangWei is a fast growing international manufacturer of construction chemicals with plants in Beijing, China. The company is specialized in preventative and remedial waterproofing products.

Preventative waterproofing products are wildly used during new construction and are usually installed by the general contractor.Examples are bentonite strips, hydrophilic mastics and rubbers, which swell in contact with water and hence block water ingress,injection hoses, which can be injected at a later stage to block water and finally cementitious coatings for basement waterproofing and elastomeric membranes for tanks and roofs.

Remedial waterproofing products are mostly used when major (or minor) water leaks happen at a later stage and are usually applied by specialist applicators. Remedial waterproofing products are also often used during construction of tunnels and other underground constructions to prevent infiltrating water from hindering the normal progress of the works. Examples are injection resins based on Polyurethanes (both 1C and 2C) and Poly-acrylates. These products are also used for Soil and Rock Stabilization,together with Organo-minerals.

LangWei also manufactures a series of products for the Protection and Repair of reinforced

Concrete. Examples are cementitious grouts and mortars, epoxy injection resins, carbon fibre laminates and epoxy glues.
