The WIG-900 series polymer composite waterproof membrane is carefully designed and developed by Jianguo Weiye. It is composed of two layers of membrane compounded on an automated production line in the factory. The overlapping parts adopt a special structure of polymer composite waterproof membrane, which is equivalent to two layers of protection with one installation.
Main raw material "Jianguo Anzhu" special basic blended asphalt: is a basic blended asphalt developed by Jianguo Weiye based on the engineering mechanism of waterproof protection of building engineering and using the ultimate state design method. Its characteristic is that the design service life under "natural environment & specific usage" is set. Within this service life, the composition of the asphalt during the aging process can always meet the basic functional requirements of waterproof protection.

1.0m*7.5m Q/FSWJG0055-2024 Product Advantages
◆ Pre-laid types have the advantages of ordinary pre-laid products, and self-adhesive types have the advantages of ordinary self-adhesive products;
◆ Two membranes are compounded automatically in the factory, with full adhesion between the two layers, realizing factory-based on-site construction;
◆ Compared with traditional two-layer membrane separate construction, one-time construction is possible, making construction more convenient and saving time;
◆ Both long and short sides adopt double-lap method, making the lap more reliable and the waterproof effect better;
◆ One installation provides two layers of protection, with higher cost performance;
◆ Pre-laid products have the advantages of WJG-921 fixed pre-laid materials, which are not afraid of external damage, not afraid of steel bar piercing and scratching, not afraid of welding slag, and can effectively protect the waterproof membrane from damage during steel bar binding.
Application Range
Pre-laid products: Widely used in underground waterproof projects, such as basement slabs, subways, corridors, tunnels, etc.;
Self-adhesive products: Widely used in roofs, basements, etc.
Construction Method
Pre-laid bonding method or self-adhesive method
Storage and Transportation
◆ When storing on site, different types and specifications of products should be stored separately and should not be mixed.
◆ Avoid sun and rain, pay attention to ventilation, and keep away from fire sources.
◆ The storage temperature should not exceed 45℃. When the rolls are placed flat, the stacking height should not exceed five layers, and when placed upright, they should be stacked in a single layer.
◆ When the on-site storage time is long, cover with tarpaulin or other shielding measures, and store directly in the warehouse if conditions permit.
◆ Determine the material storage location in advance to reduce secondary handling. During handling, handle with care to avoid material damage.
◆ The storage period is at least 1 year from the date of production.
