WG-985 high-strength, flame-retardant, polymer composite pre-laid waterproof membrane is a 1.2mm high-strength, flame-retardant, polymer self-adhesive membrane pre-laid waterproof membrane and a 1.5mm HCS-1000 reaction-type polymer cross-membrane wet-laid waterproof membrane, which are factory-composite produced. The pre-laid, anti-adhesive construction of the WG-985 high-strength, flame-retardant, polymer composite pre-laid waterproof membrane provides double protection with a single installation.
Serial Number Name Thickness (mm) Width*Length Implementation Standard 1 WJG-985 High-Strength, Flame-Retardant, Polymer Composite Pre-laid Waterproof Membrane 2.7 1.0m*10m Q/FSWJG0052-2024 Product Advantages
◆ Two types of membranes are factory-automated composite, with full adhesion between the two layers, achieving factory-level on-site construction;
◆ Compared with the traditional two-layer separate construction, it can be completed in one step, making construction more convenient and saving time;
◆ Double lap joints on both the long and short sides, making the lap joint more reliable and the waterproof effect more excellent;
◆ Double protection with a single installation, higher cost performance.
◆ Possesses all the advantages of ordinary pre-laid membranes.
◆ Possesses the advantages of WG-980 high-strength flame-retardant pre-laid materials, such as being resistant to external damage, not afraid of steel bar punctures and scratches, not afraid of welding slag, and effectively protecting the waterproof membrane from damage during steel bar binding.
Application Range
Widely used in underground waterproofing projects, such as basement slabs, subways, pipelines, tunnels, etc.
Construction Method
Pre-laid anti-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 laid flat, the stacking height should not exceed five layers, and when they are 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.
