Asphalt waterproofing membrane: a rollable sheet waterproofing material made of asphalt on the tire base and then sprinkled on the surface with an isolation material.

1. Modified asphalt waterproofing membrane: soft, can be made into 4-5mm thickness, can be used in a single layer, divided into:

Modified asphalt waterproofing membrane: It can be used in the temperature range of -25-100, with high elasticity and strong puncture resistance.

Modified asphalt waterproofing membrane: Plastic modified asphalt waterproofing membrane refined by advanced technology with APP or APAO and APO modified asphalt as dipping materials, high-quality polyester felt, glass fiber felt, and composite tire cloth as the tire base, and fine sand and mineral PE film as negative materials.

2. Self-adhesive waterproofing membrane: no adhesive, no need to heat and bake until melting, just tear off the isolation layer, and it can be firmly bonded to the base layer.

3. Polymer waterproofing membrane, such as:

Waterproofing membrane: It is a thermoplastic polymer waterproofing membrane that is used more and is manufactured by a special extrusion coating process.

Waterproofing membrane: a new type of waterproofing membrane made of thermoplastic polyolefin (TPO) synthetic resin that combines ethylene propylene rubber and polypropylene with advanced polymerization technology as the base material, adding antioxidants, antioxidants and softeners, is a synthetic polymer waterproofing membrane.

Waterproof materials are first divided into major categories, that is, flexible waterproof materials and rigid waterproof materials. Flexible waterproof materials are further divided into waterproofing membranes, waterproof coatings, and sealing materials. Rigid waterproofing materials are roughly divided into silicone waterproofing materials, fatty acid waterproofing materials, and other types of waterproofing agents.

In home decoration, marble or vitrified tiles are generally used in the entrance hallway and living room. Its advantages are that it is easy to clean, has a luxurious appearance, has a long service life, and is not afraid of being scratched. The disadvantage is that natural stone is expensive and heavier, and its weight will have a certain impact on the building.

Wood flooring is generally used in living rooms, bedrooms and other areas, and there are two types of flooring, namely solid wood flooring and laminate flooring. The advantages of solid wood flooring are natural warm colors, soft feet, relatively comfortable, natural texture, and excellent texture. The disadvantage is that the wood shrinks and swells, is easy to deform, easy to be moth-eaten, complicated to maintain, and easy to lose luster over time.

Laminate flooring is very wear-resistant, scratch-resistant, deformation-resistant, and easy to clean, easy to install.

5.Home color: the main waterproof coating building materials.

6.Gushuibao: The company is mainly engaged in waterproof coating products. After past expansion, its products include waterproof coatings, tile adhesives and other products.

At present, building waterproofing materials can be roughly divided into five categories: asphalt waterproofing membranes, polymer waterproof sheets, building waterproof coatings, building sealing materials and waterproof materials for special purposes such as anti-seepage and leakage plugging. Each material has its own characteristics, so it is necessary to select appropriate materials according to the location, conditions, environment, grade and functional needs of the project, and give full play to the characteristics of various materials to obtain the best waterproof effect.

According to the selection of materials according to different engineering parts, the selection of signs is also inconsistent.

1) Roofing. Due to long-term exposure of the roof, direct erosion by sunlight, snow and rain, and large changes in the temperature of severe winter, the roof panel will also expand and contract between day and night, so materials with good aging resistance, certain extensibility and high heat resistance should be selected. Such as polyester tire modified asphalt membrane, EPDM sheet or asphalt linoleum, etc.

2) Underground. According to the characteristics of underground engineering in a wet state for a long time and difficult to maintain, but the temperature difference is small, it is necessary to use a rigid-flexible combination of multi-channel fortification, in addition to the rigid waterproof filler, should also choose mildew resistance, good corrosion resistance, long service life of flexible materials. When waterproofing the cushion, materials with good puncture resistance should be selected, such as glass fiber tires with a thickness of 3mm or 4mm, modified asphalt membranes for polyester tires, glass cloth linoleum, etc.; When using polymer waterproof substrate, a binder with good water resistance must be selected, and the thickness of the substrate should not be less than; When choosing waterproof coatings, it is necessary to choose materials that form quickly and do not produce reemulsification.

Such as polyurethane vinegar, silicone rubber waterproof coating, etc., its thickness should not be less than.

3) Toilet and bath. The general area of the toilet and bathroom is not large, there are many yin and yang angles, and there are many pipes through the floor, and the construction of membranes and sheets is difficult, so it is advisable to choose waterproof coatings, and the coating can form an overall seamless coating film, which is not affected by the concave and convex shape of the base surface, such as JS composite waterproof coatings, butadiene latex asphalt coatings, polyurethane waterproof coatings, etc. For the pipes that pass through the floor slab, they can be treated with sealing green or water-swelling rubber strips.

Waterproofing materials can be broadly divided into three categories: waterproofing membranes, polyurethane waterproofing materials, and polymer cement-based waterproofing materials. The forms can be divided into:

Waterproof coating and waterproofing membrane, waterproofing membrane: waterproofing membrane is the core part of waterproofing, playing the role of filtration, absorption and reinforcement, waterproofing membrane is made of thick paper or fiber fabric as the base material, with asphalt or other synthetic polymer waterproof materials dipped.

coils. Waterproofing membranes are not only used for indoor waterproofing, but also for waterproofing and reinforcing materials for highways and other buildings. The waterproofing membrane not only has waterproof performance, but also has high temperature resistance and toughness.

Polyurethane waterproofing material: This is a form waterproof coating, a semi-liquid two-component reaction-curing synthetic polymer waterproof coating. 911 polyurethane waterproofing material is mainly used for the top and bottom of the waterproofing membrane, the water under the insulation wall below penetrates into the outside of the wall, and the water outside penetrates into the upper part.

All the way to the bottom. The combination of waterproofing coating and waterproofing membrane can produce a better waterproofing effect and is regarded as a complete waterproofing project.

Polymer cement-based waterproofing material: This new waterproofing material has a better waterproofing effect than traditional waterproofing membranes. It is a two-component waterproof coating composed of a liquid material composed of synthetic polymer emulsion and various additives and supporting powders.

It is an elastic material made of synthetic polymer materials.

The waterproof material is the envelope of the building to prevent the penetration of rainwater, snow water and groundwater; It is necessary to prevent the erosion of moisture, vapor and other harmful gases and liquids in the air; The separating structure should prevent the seepage of water supply and drainage. These materials are collectively referred to as those that are resistant to impermeation, leakage, and erosion.

Prevent rainwater, groundwater, industrial and civil water supply and drainage, corrosive liquids, moisture and vapor in the air from invading the building materials. The main parts of the building that need to be waterproofed are the roof, wall, ground and basement.
