Description
Technical Field
[0001] The utility model relates to the technical field of waterproof coiled materials, in particular to a pre-laid waterproof coiled material with a sand surface. Background Art
[0002] Pre-laid waterproofing membrane with sand surface is a building material specially designed for underground waterproofing projects. This membrane is usually self-adhesive and can be directly adhered to the surface of the structure without additional adhesive. The surface of the membrane is covered with a layer of sand particles. These sand particles can increase the friction between the membrane and the concrete structure, thereby improving the overall stability and anti-seepage performance of the waterproof layer. The design with sand surface also helps to achieve rapid laying and reduce the formation of bubbles during the construction process.
[0003] At present, when the existing waterproof membrane is laid, there will be overlaps between the membranes. According to existing experience, the overlap width is generally 10 cm, which is better. There are slight differences according to different designs. When laying, the existing membrane roller is generally controlled to roll and lay. The overlap width between the membranes is generally controlled by workers using a tape measure. When laying, the overlap width is prone to deviation, resulting in poor laying effect. In order to solve this technical problem, the utility model proposes a pre-laid waterproof membrane with a sand surface. Utility Model Content
