It is a kind of self-adhesive waterproof coiled material based on macromolecular rubber and superior bitumen with polyethylene film and aluminium foil surface material or no film(one self-adhesive side). And adopt the package with preventing adhesion isolation layer. The coiled material have perfect property,simple operation,no pollution ect characteristic,which includes no fiber and Polyester fiber.
Good flexibility,creep properties and malleability.
Strict adhesion between waterproof layer and basic layer,no leaking.Having self healing ability after impaling.
Good flexibility:can withstand small settlement and shrinkage deformation.
Anti-corrosion：resistance to soil erosion, groundwater infiltration, and effective external protection.
Operation without heating.Pasting by itself with superstrong connection of sheet material and adhesion of same base.
Convenient and safe operation,no pollution.

Widely applied to waterproof projects of roofing,basement,tunnel,subway and subway.And also used for other proofing of waterproof projects with wood and metal construction.
The base must be strong,smooth,dry,no dirt and greasy dirt.If containing too many water,the base must be coated.
Treatment agent:Reference quantity: 0.2kg/m2.Stir and brush evenly via roller brush.The base muse be clean.If there is dirt on coated base after drying,it should be coated again to guareantee the quality of bonding.
The treatment of small part:The additional layer need to be done at root of pipe,side of pipe outlet and ying & yang corners.The size should meet the criterion of design.
Posting of material:If the drainage is required,the datum line must be drawn at low section.
Unfold the sheet material along with the datum line from low section to high section and uncover the release paper。The width of lap joint is 60-80mm between two pieces sheet material.After finishing posting material,the sheet material and lap joint are compacted.
The treatment of end:The flat surface,vertical face and groove are sealed by sealant.The vertical face need to be fixed by press bar then sealed with sealant.
The protect of finishing operation:The finished material should be protected immediately or do next step.If there is bubble or damaged part.That must be repaired in time.The damaged part need to be repaired by unwounded 150mm sheet material then compacted and sealed by sealant.
The operation temperature is above 15℃.The low temperature product can be used in winter.
The protection layer is coved as far as possible.The sheet material with plastic film and sand surface can’t be shined directly.
Storing:Keeing in drying and ventilated place.Avoiding shining and raining. Height of stack not more than 5 layers.Shelf life:12 months.
