Floor waterproofing project is a hidden project, although the project is very small, but the impact on the future is significant. Many homeowners just contact home improvement is not very familiar with the ground waterproofing materials, here to introduce you to the ground waterproofing materials which.
What are the waterproofing materials on the ground]
1, asphalt-type waterproofing materials. Natural asphalt, petroleum asphalt and coal asphalt as the main raw material, made of asphalt linoleum, paper-tread asphalt linoleum, solvent-based and water-emulsion asphalt or asphalt-rubber-based coatings, ointment, with good adhesion, plasticity, water resistance, corrosion resistance and durability.
2, rubber and plastic-type waterproofing materials. Neoprene, butyl rubber, EPDM rubber, polyvinyl chloride, polyisobutylene and polyurethane and other raw materials, can be made of elastic tire waterproofing membrane, waterproof film, waterproof coatings, coating materials and plasters, mastics, water stops and other sealing materials, with high tensile strength, elasticity and elongation, bonding, water resistance and good weather resistance, etc., can be used cold, with a long service life.
3, cement-based waterproofing materials. The cement has the role of promoting the solidification of admixtures, such as water repellents, aerators and expansion agents, etc., can enhance the cement mortar and concrete hydrophobicity and impermeability; cement and sodium silicate as the base material configuration of the promotion of condensation mortar, can be used for underground engineering plugging waterproofing.
4, metal-type waterproofing materials. Thin steel plate, galvanized steel plate, pressed steel plate, coated steel plate, etc. can be used directly as a roof panel for waterproofing. Thin steel plate used in basements or underground structures of metal waterproofing layer. Thin copper plate, thin aluminum plate, stainless steel plate can be made into the building deformation joints of the water stop. Metal waterproofing layer of the connection to be welded, and painted with rust-proof protective paint.

Material prices: due to the kitchen, bathroom and other locations such as pipes, small areas, so home furnishings are particularly suitable for the use of cement-based waterproofing coatings, these products are water-based coatings, non-toxic, non-polluting, simple and fast construction, and cement substrate bonding tight, long service life, waterproofing effect, moderate price and other significant features. The price of such waterproofing materials is usually: general-purpose (i.e. rigid) 20kg / set 280 ~ 350 yuan; flexible 20kg / set 350 ~ 480 yuan.
Price of labor: the family is generally the kitchen bathroom floor and walls to do waterproofing, the standard price in 65 yuan / square meter. If you ask skilled workers construction, waterproofing market prices in the 60-100 yuan / square meter or so, accounting for about 1% of the cost of renovation.
Waterproof area calculation: bathroom waterproof area (square meters) = [(bathroom floor perimeter – width of the door) × 1.8 m (high) + (ground area)]; kitchen waterproof area (square meters) = [(kitchen floor perimeter – width of the door) × 0.3 m (high) + (ground area)].
[Ground waterproofing material construction method]
The first step, we should observe and combine the bathroom plumbing and electrical circuit to transform the actual situation, and have a detailed understanding of the hidden project. Determine a good plan, and then the plumbing and heating pipes to lay chisel flat. Second, in the grassroots treatment, in the bathroom before the waterproofing project should be cleaned up its original decorative materials, and then use cement slurry to pave several surfaces, followed by waterproofing treatment.
The second step, when doing waterproofing layer, should pay attention to whether the waterproofing coating is evenly painted, the thickness of the waterproofing layer should be more than 1.5mm, pay attention to the dead ends, joints do waterproofing treatment. Construction should also be completed after 24 hours of sheltered water test: all the bathroom sewer blocked, in the doorway to build a 25cm height of the can, in the injection of 20cm height of water, after 24 hours, observe whether there is a leak, if there should be timely repair.
The third step, after 5-7 days in the sheltered water test waterproof coating has formed a waterproof film, should also be made on the waterproof coating layer of cement mortar protection layer. This can be done to effectively protect the waterproof coating, two convenient tile, while the pipeline can play a good leak-proof waterproof pressure. The last process is the laying of wall and floor tiles.
