Method for checking construction effect of polymer self-adhesive waterproof coiled material

Polymer self-adhesive waterproof coiled material is made of rubber, petroleum asphalt, etc. as the base material, filled with filling materials, covered with aluminum foil on the top and polyethylene film on the bottom, and refined by special process. It has the advantages of good elongation and bonding performance.

After the completion of the construction with polymer self-adhesive waterproof coiled material, what methods need to be adopted to test the construction effect, and where the construction effect needs to be carefully checked? Let's introduce it to you.

1. The exhaust duct of the exhaust roof shall be vertically and horizontally connected without blockage. The exhaust pipe must be firmly installed, correctly positioned and tightly sealed. Test method: observation and inspection.

2. The paving direction of coiled material shall be correct, and the allowable large deviation of lap width of coiled material is - 10mm. Inspection method: observation and ruler inspection.

3. The lap joint of polymer self-adhesive waterproof coiled material layer shall be firmly bonded (welded) and tightly sealed without defects such as wrinkle, edge warping and bubbling; The end of the waterproof layer shall be bonded and fixed with the base course, and the seam shall be sealed tightly without edge warping. Test method: observation and inspection.

4. The spreading material and light color coating protective layer on the polymer self-adhesive waterproof coiled material layer must be spread or brushed evenly and bonded firmly; Cement mortar, block or fine aggregate concrete protective layer and polymer self-adhesive waterproof coiled material layer need to be provided with isolation layer; The retention of rigid protective layer and dividing joint shall meet the design requirements.
