Joint sealing treatment: the detailed joints of coil splicing (mainly the three-dimensional angle and the position with large stress after coil splicing) are sealed with adhesive tape.
⑤ It forms a permanent organic combination with the concrete, is not affected by the displacement of the base layer, and can maintain high peel strength in the long-term immersion environment.
This method is applicable to dry base.
The grass roots are cleaned up in the details of Yin-Yang corner, post pouring belt, high and low span, water collecting pit, and foundation pit.
product introduction polymer self-adhesive film waterproof coiled material is composed of polymer compound main material, self-adhesive film layer It is a new type of waterproof coiled material composed of anti sticking and anti sticking material layer (except the overlapping edge area) and isolation material layer (when necessary) to bond with post cast concrete and prevent water channeling on the bonding surface.
After removing the surface isolation film, paste the upper butt joint coil and roll it to make it firmly bonded.

Three.
③ The excellent puncture resistance enables it to bind the reinforcement directly after paving.
④ It has strong heat insulation, water resistance, compression resistance and moisture resistance.
The surface of the waterproofing membrane can not be crisp, burr, sand and so on.
② Coil butt joint: the bonding material of butt joint coil is coil (without particle anti sticking layer).
Cut the coil into a strip and place the adhesive surface upward.
Part II: additional layer setting part III: waterproof coiled material lapping (key) long side coiled material lapping: directly lap and roll after removing the isolation film on the lap side of coiled material.
The sundries, dust and ash of the base course shall be cleaned, and the base course shall be accepted.
Roll it to make it bond firmly.
Part V: treatment of special parts ① treatment of pile head ② treatment of internal and external corners ③ treatment of through wall pipe fittings ④ treatment of post cast strip [source: Huarui waterproof] Disclaimer: release, excerpt.
Hondar, the waterproof star, Hongda Hongda waterproof emulsion, copper wave waterproofing Sheng Sheng three and waterproof two performance characteristics: Single Layer Paving can achieve first class waterproof effect.
The fourth parts are waterproof, waterproof, waterproof, and waterproofing.
The first part of the construction process of waterproofing membrane is to deal with the waterproofing membrane at the grass-roots level.
This method is applicable to the situation that the waterproof layer may be soaked in rain, so as to avoid separation.
If necessary, heat the tape properly, and the bonding effect is more ideal.
Use broom, shovel and other tools to clean the surface protrusions, and then the construction can be carried out.
When the basement floor coiled material waterproof layer is laid by the empty laying method, it can be constructed on the wet base course, but the base course shall be solid and free of open water.
② Convenient construction, no protective layer, environmental protection and no pollution.
When the polymer self-adhesive film waterproof coiled material has large penetrating damage, the sand particles on the upper surface of the damaged part shall be removed with a hot-air shovel (the range shall not be less than 70mm in all directions beyond the damaged range), then the adhesive tape shall be pasted, and then a piece of coiled material shall be used as a “patch”; Other situations can be repaired directly with adhesive tape as appropriate; If only small pieces of glue and sand are missing in the coil, it is not necessary to repair.
Remove the isolation film on the upper surface of the tape after rolling, and paste the lap upper coiled material on the tape.
Lap in the short side direction: ① lap of coiled material: remove the isolation film on the lower surface of polymer double-sided self-adhesive tape (hereinafter referred to as “tape”) and paste it on the lap lower coiled material.
