1. Treatment of the base layer: The base layer should be cleaned thoroughly, and there should be no dust or debris on the surface. If the surface is dry, it should be moistened with water first, but there should be no residual water.

2. Collocation of bonding glue: when the weight ratio of polyvinyl alcohol to cement is 1:5, 0.4 to 0.43 kg of water is required to be added to each kg of cement. If the weight ratio of polyvinyl alcohol glue to cement is 1:10, 0.47 to 0.5 kg of water is required to be added to each kg of cement. When preparing, we need to put 107 glue into the glue making container, add water while mixing SBS waterproof coiled materials, until the polyvinyl alcohol glue is completely dissolved after mixing with water, and then mix while adding cement until there is no clot, no sediment, and no foam.

3. Treatment of complex parts: When constructing the waterproof layer, the first step is to prepare an additional layer for the complex part according to the requirements of the drawing. The additional layer for the complex part needs to be bonded with rolls, cement glue, or polyurethane glue.

4. When laying a large area of internally reinforced waterproofing membrane: If it is a composite membrane, the composite membrane can be pre laid 3 to 12 meters at the laying location. If it is an underground project, it can be placed 2 to 3 meters. After aligning the direction, the PVC waterproofing membrane will be fixed in the middle, one end of the membrane will be fixed and pasted, and after pasting it, the other end of the pre laid membrane will be placed back in the bonded position for continuous laying until completion.

5. Construction of protective layer: When the reinforced waterproofing membrane is exposed on the outside, in order to prevent accidental damage or exposure to ultraviolet rays, the protective layer should be extended to prolong the service life of the composite membrane. The main protection method is cement material.

There are three common construction processes for waterproofing with roll materials: 1. Hot construction process, 2. Cold construction process, and mechanical fixing process. There are four methods for laying, including full adhesion method, empty laying method, strip adhesion method, and point adhesion method. TPO waterproofing roll materials.

During construction, appropriate construction methods should be selected based on different design requirements, materials, and specific conditions of the project.

In the hot construction process, there are three different situations: (1) Hot Mastic Adhesive Method.

The traditional construction method involves pouring hot mastic while rolling and laying oil felt, layer by layer. The suitable range is: petroleum asphalt oil felt, three felt, four oil (two felt, three oil) layered laying.

(2) Hot melt method.

The method is to use a flame heater to melt the hot melt adhesive at the bottom of the hot-melt waterproofing membrane for bonding, applicable to the overlapping seam welding of thermoplastic synthetic polymer waterproofing membranes.

(3) Hot air welding:.

The common method is to use hot air welding polymer self-adhesive film waterproofing membrane to heat the waterproofing membrane lap joint for bonding. Scope of application: Welding of thermoplastic synthetic polymer waterproofing membrane lap joint.

2. The cold construction method also includes three different methods.

(1) Cold horse hoof paste method.

The method is to use cold asphalt bonding materials prepared by the factory, which do not require heating during construction. They can be directly applied and scraped before pasting the asphalt felt. The scope of application is: petroleum asphalt felt, three felt, four oil (two felt, three oil) laminated paving.

(2) Cold adhesion method.

The method is to use adhesive to bond the roll to the base layer and roll to roll without heating. Applicable scope: synthetic polymer roll, polymer modified asphalt waterproofing roll.

(3 liquid rolls) self-adhesive method.

The method is to use a waterproof membrane with self-adhesive, which does not require hot construction or coating of adhesive materials, and can be directly bonded. The scope of application is synthetic polymer waterproof membranes with self-adhesive and polymer modified asphalt waterproof membranes.

There are also two different situations in the mechanical fixation method.

(1) Mechanical nail pressing method.

The method is to use galvanized steel or copper nails to fix the waterproof layer of the roll material, which is mainly used for laying high polymer modified asphalt rolls on wooden substrates.

(2) Burial method.

The method is that the roll material is not bonded to most of the base layer, and is buried with pebbles on top. However, the lap joints and surrounding areas are fully bonded, and it is suitable for use in empty paving methods and inverted houses.
