Manufacturer of self-adhesive polymer waterproofing membrane: precautions and construction methods for waterproofing membrane

When using waterproof rolls, we need to evenly apply adhesive on its surface. Polypropylene waterproof rolls should not be exposed and should be used immediately after painting, otherwise the waterproof effect will be affected over time.
When using waterproof materials, we also need to level the laid ground, clean the ground, and sprinkle water to keep the ground moist.
3. In order to make it work, we can apply glue to some areas that are prone to water leakage in advance, so that they will not leak in the future, otherwise it will easily leak over time.
4. The cement used in the production of adhesives must be mixed evenly without any sedimentation or cement blocks.
5. When laying polypropylene waterproofing membrane, it is not allowed to fold the polypropylene waterproofing membrane, which may affect the waterproofing effect.

Manufacturer of self-adhesive polymer waterproofing membrane: Construction technology of waterproofing membrane

1. Firstly, waterproof materials and various construction tools need to be prepared, followed by the specific construction process. Firstly, the treatment of the base layer must be carried out. Before construction, the base layer must be cleaned to ensure that there are no other lumps or debris, and the base layer must be dry, with a moisture content within 9%.

2. During the paving process of coiled materials, it is necessary to understand the size of the paving range, from low to high. When paving the ground, attention should be paid to the treatment of complex parts, such as drainage holes in wall corners. An additional layer should be made in these complex parts to prevent water leakage from affecting daily life.

Manufacturer of self-adhesive polymer waterproof rolls: How can we judge the quality of waterproof rolls?

1. For the quality of manufacturers and products, it is recommended to conduct on-site inspections and evaluate the production scale of the manufacturers to see if the storage capacity of SBS modified asphalt, modifiers, and asphalt materials can meet the requirements for the required amount of construction projects; Is the asphalt waterproof roll production workshop equipped with automatic batching, automatic rolling, and equipment operation.

2. Using peel identification

Firstly, the material of elastic asphalt waterproofing membrane has excellent elasticity, so the material layer can be peeled off by hand, the asphalt layer can be stretched, and then released. If it can be stretched for a long time, it can still recover after being released, indicating that the product is made of modified asphalt. If the asphalt cannot be stretched, the asphalt layer has no elasticity, the coil cannot rebound after being broken by hand, and the surface cracks, then the surface asphalt layer is easily removed by hand, It is possible that a large amount of recycled rubber is added to the material, or too many modifiers are added to waste rubber and recycled rubber, which may not guarantee the quality of the product.

3. Fire identification

The high-quality elastomer asphalt waterproof roll material additive is SBS modifier, which is ignited on the cardboard and gently stretched upwards; The additive for inferior waterproof rolls is waste rubber powder, burned on cardboard, and then gently stretched upwards without stretching.
