DN450 waterproof casing 02s404 flexible waterproof casing rigid waterproof casing

Basic knowledge of waterproofing casing leakage repair and waterproofing. Synthetic polymer waterproofing membrane is based on synthetic rubber, synthetic resin or a blend of the two, adding appropriate amounts of chemical additives and fillers, etc., and is processed through different processes. Rollable sheet-like waterproof materials, or composite the above materials with synthetic fibers to form two or more layers of curlable sheet-like waterproof materials.
, Lengmawangdi grease is a cold asphalt cementing material prepared from petroleum asphalt, fillers, solvents, etc.
In order to enhance the bonding force between the waterproof material and the base layer, the base treatment agent is a paint that is pre-painted on the base layer before the construction of the waterproof layer.
In order to reduce cracks, dividing joints are pre-set joints on the roof leveling layer, rigid waterproof layer, and rigid protective layer. The rigid protective layer only forms grooves on the surface, which are called surface grid joints.
When paving waterproof materials with the full-adhesive method (full-adhesive method), the membrane and the base layer are fully bonded.
When laying waterproofing membranes using the waterproofing and leak-proofing method, the membranes and the base layer are only bonded within a certain width around them, and the remaining parts are not bonded.
When paving waterproof membranes using the strip-pasting method, the membrane and the base layer adopt a strip-shaped bonding construction method. There should be at least two bonding surfaces between each roll and the base layer, and the width of each strip should be no less than 1.
When paving waterproof membranes using the point-bonding method, the membrane or perforated membrane and the base layer adopt a point-like bonding construction method. There should be no less than 1 bonding point per square meter, and the area of each point is .
