PVC waterproof membrane is a kind of waterproof material, there are many waterproof materials, its construction process will be different, then what are the PVC waterproof membrane construction process and waterproof membrane construction precautions? Let's take a look at the construction process of PVC waterproof membrane and see what are the precautions for waterproof membrane construction ! Construction process of PVC waterproof membrane There are three kinds of construction methods for PVC waterproof coiled materials, which are full sticking method, empty paving method and mechanical fixing method. The following editors will introduce you one by one. 1. Full stick method (1) Before the construction of the waterproof coiled material, first lay the coiled material on the surface of the base layer without bonding first. Note that the coiled material should be straight and smooth when laying, the material cannot be twisted, and the width of the longitudinal overlap of the PVC waterproof coiled material is 50mm It needs to be properly cut, and the transverse direction is usually butt processing. A 200-250mm wide non-composite layer is used above it, and the PVC waterproof coiled material is covered and welded. (2) Fold the long sides of multiple waterproof membranes in half, apply adhesive to the folds of the base layer and the surface of the membrane, and when the adhesive dries to the point where it does not stick to your hands, the pre-laid waterproof membrane The surface is closed and pasted, and compacted with a pressure roller. (3) Fold up the parts that are not folded, continue to use the above method to paste and compact, and then just weld the butt joint. 2. Empty paving method (1) First lay in accordance with the laying method of the full-bonding method, and then fully bond the surrounding of the overall waterproofing project with coiled material, and weld the lap joint. (2) Butt processing is adopted in the horizontal direction, and a 200-250mm wide coil is used to cover the lap and weld. 3. Mechanical fixing method (1) The first step of the mechanical fixing method is the same as the full-bonding method. You can refer to the first method of the full-bonding method, and then the longitudinal overlap width is 100mm, of which 50mm is used as a fixing piece, and the fixing piece should pass through the insulation Layer, then fixed overlying the structural layer. (2) First punch holes with impact drills according to the designed spacing, the hole diameter should not be too large, and it should be smaller than the size of the fixed outer diameter. After the fixing parts are in place, tighten them with a screwdriver. After the fixing parts are fixed, lap each one For welding, the same horizontal butt joint treatment is used, and the lap joint is covered with a 200-250mm wide roll material and welded. Matters needing attention in the construction of PVC waterproof membrane 1. The temperature of the construction environment should be paid attention to when laying the coiled material. The temperature of the waterproof coiled material is above -5 degrees. If the full stick method is used, the temperature of the coiled material can only be above 5 degrees. 2. An additional layer should be used for the construction of waterproof membranes in special locations. 3. Before the completion of the construction, the waterproof membrane should be temporarily fixed to avoid being blown away due to strong winds. 4. The construction of the waterproof layer must be carried out after the construction of the previous process is completed, and cannot be cross-constructed. If the equipment is to be installed on the laid waterproof coiled material, an additional layer must be treated at its location. Editor's summary: The above is the relevant content of the construction process of PVC waterproof membrane and the precautions for waterproof membrane construction . Everyone can follow the above construction process and pay attention to the above precautions during construction. I hope to help everyone. What, the decoration still uses his own money? !
