The pool is an important device for storing water, but it is prone to seepage problems when the pool is used for a long time. It is necessary to know that repairing this leakage project is still relatively large, and it is also necessary to choose waterproof materials. The following Xiao Bian will introduce to you the methods of pool plugging and what materials are generally used for pool waterproofing.
What are the methods of plugging the pool?
1, point leakage does not leak
First, when doing the water avoidance test, there is enough water pressure after the water injection. At this time, identify the leak point from the outside of the pool and mark it. After the test, you can find out the corresponding position of the inner wall of the pool. Before making the waterproof cement mortar, leak water at the inside and outside of the tank body and make up for the weak parts. Cut and cut the surface of the leaking point and the weak part firstly. The depth reaches about 3-5cm, clean up, and then use it again. The plugging king handled it. For crack leaks, then you can chisel a 3-5cm deep v-groove along the crack. For leaking holes, first drill the hole in a 3-10cm deep funnel shape and clean the surroundings.
2, waterproof cement mortar surface
If there is a honeycomb and loose concrete in the concrete wall, kick it out, rinse it with water, and smooth it with 1:3 cement mortar. Mix the cement and water again. At this time, add the waterproof oil and mix it evenly. Then use a soft-bristle brush to evenly brush the surface of the base layer, then wipe the bottom waterproof mortar. After the bottom ash was wiped off, it was separated by 1d at room temperature, and then it was brushed with cement slurry. The mixing ratio and practice were the same. After brushing the pulp, it is necessary to pay attention to the next layer, with the same ratio as the bottom mortar, plaster thickness of 5-10mm or so, before the solidification with a wooden trowel leveling, this time can be flattened with an iron trowel .
3, the bottom of the tank wipe cement mortar waterproof layer
Clean loose concrete, mortar, etc. on the cushion, then add appropriate amount of cement slurry, spread on the ground, and sweep it evenly with a broom. Put the mortar on the ground floor, pour the mixed mortar on the ground, scrape with a ruler, flatten the wood trowel, and press the iron trowel again. After brushing the cement slurry, the next step is to wipe the surface layer mortar, then the initial layer of mortar and then brush the final pulp.
What is the general material for pool waterproofing?
1. Bituminous waterproof material: This material is based on natural asphalt, petroleum asphalt and coal asphalt. It is made of asphalt tar mats, paper tire asphalt tar mats, solvent-based asphalt emulsions, or asphalt rubbers. Coatings, ointments, so use it has good adhesion, plasticity, water resistance, corrosion resistance and durability.
2, rubber plastic waterproof material: neoprene rubber, butyl rubber, ethylene propylene diene monomer, polyvinyl chloride, polyisobutylene and polyurethane and other raw materials, so it can be made of elastic tireless waterproof membrane, waterproof film, Waterproof coating, coating material and ointment, cement, sealing tape and other sealing materials, use it has high tensile strength, elasticity and elongation, bonding, water resistance and weather resistance and so on.
3, cement waterproof material: Admixtures for the coagulation and solidification of cement, such as water repellent, air entraining agent and expansion agent, etc., this can enhance the hydrophobicity and impermeability of cement mortar and concrete; The coagulation mortar with sodium silicate as the base material is also a plugging and waterproofing of the underground works.
4, metal waterproof material: thin steel plate, galvanized steel, profiled steel, coated steel plate can be used directly as a roof, but also can play a role in waterproofing. Thin steel sheets are more suitable for metal waterproofing in basement or underground structures. Thin copper plates, thin aluminum plates, and stainless steel plates can be used as waterproofing strips for building deformation joints.
Summary: What are the methods for plugging pools and what materials are generally used for pool waterproofing? Here are some of the relevant materials. When you find that the pool is leaking, you must find the right method and choose the right material. The role played by different waterproof materials is also different. I hope that the above introduction will help everyone.
