Construction waterproof engineering classification. The classification can be based on the location of the fortification, the method of fortification, the material properties and species used for the fortification.
1, according to the fortification of the site classification According to building (structure) building project leakage of water, the main parts can be divided into: roof waterproof, underground waterproof, indoor toilet bathroom waterproof, exterior wall waterproof and special construction (building) Things and parts waterproof.
1) Roof waterproofing
2) Waterproofing of underground waterproof basements, underground trenches, ground railroads, tunnels, and underground structures)
3) Indoor toilets and baths shall be waterproof with J waterproof toilets, bathrooms, bathrooms, empty spaces, and open water, as well as floors, floors, and pipelines;
4) Waterproofing of external wall facades, quilt cover, panel seams, window edges, window sills, beam bottoms, and column edges;
5) Waterproof of special buildings (structures) and parts such as water pools, water towers, indoor swimming pools, fountains, four-season halls, indoor gardens, oil storage tanks, and oil storage tanks.
2, according to no defense method classification According to the fortification method classification, can be divided into composite waterproof and constructed from waterproof.
1)Composite waterproofing uses a variety of waterproof materials for waterproofing (composite waterproofing) is a new type of waterproofing method. In the fortification, a variety of different performances of the waterproof material are used. Various waterproof material advantages. In order to improve the overall performance of the waterproofing process, it is possible to achieve a combination of “just-in-buy combination, multi-channel protection, and comprehensive managementâ€. For example, at the joints, waterproof materials with different sealing materials or properties can be used in combination with large-area general waterproof materials to form composite waterproof.
2) Self-waterproof construction—The fixed form or method is used to construct the self-waterproof or combination drain for waterproofing. Such as the subway station to prevent side wall seepage water used in the double side wall fill wall (compensated shrinkage waterproof reinforced concrete), in order to prevent cracks in the roof structure to set the induced joints and post-casting belt, force to solve the subway structure of the original Y7 in the floor Under the filter layer (seepage and drainage layer) and so on.
3, classified according to the performance of the fortification material according to the performance of the fortification material, can be divided into rigid waterproof and flexible waterproof.
1) Rigid Waterproof Rigid Waterproof refers to a waterproof layer composed of plain pulp, cement slurry and waterproof mortar (water does not leak). It is the use of uniform pressure, density, solidified mortar and mortar layer alternate construction to form a whole waterproof layer. Because of the interphase pressure, the remaining capillary channels of each layer make up for each other, thus blocking the channel for seepage of water, and therefore have a high impermeability.
2) Flexible waterproof Flexible waterproof material based on the role of waterproof can also be divided into coil waterproof, waterproof coating and many other.
a. The waterproofing of coiled waterproofing membranes is to glue several layers of the coiling material to the structural base layer with a cementitious material to form a waterproof layer. This type of waterproof technology is currently used more commonly and is commonly used in waterproofing projects for roofs, basements and underground structures. In the roofing project, it is mostly used for flat roofs and roof projects with small slopes. The usual practice is to use three felts and four oils to lay mung bean sand protective layers on top; in underground waterproofing works, three felts and four oils are used for preventing the coil layer. Damaged, the surface needs to add a protective layer. Roll waterproof material can be divided into three categories: asphalt waterproof membrane, polymer modified asphalt waterproof membrane, synthetic polymer waterproof membrane.
b. Coating Waterproof and waterproof coating mainly uses emulsified asphalt, modified asphalt, rubber, and synthetic resin as the main waterproof material. It is an amorphous, viscous, liquid material before curing. It sprays, coats and coats glass on the construction surface. Fiber cloth or polyester fiber reinforced non-woven fabric, cross-linked curing or solvent, water evaporation curing to form the overall waterproof coating, after curing to form a dense material with water-impermeability and - a set of weather resistance, elongation, as the coating is The amorphous material is highly adaptable to any complex substrate surface during coating application and forms an integral waterproof layer with a seam after curing. Film coating waterproof has obvious advantages for the construction of complex parts. Because most of the materials are cold work, the construction is very simple. Therefore, it has been widely used in the construction of waterproof construction projects.
4, according to the variety of fortification material classification Waterproof upper range by fortification material varieties can be divided into: coil waterproof, waterproof coating, sealing material waterproof, concrete waterproof, waterproof powder material hydrophobic, penetrant waterproof and so on.
