Pool waterproofing practice, how to do waterproofing of cisterns

Your practice is already very good, it should be said that use medium mortar to make a layer of internal plastering.

No more than 3cm, before wiping, throw a layer of cement slurry on the concrete surface, and then cover the surface with waterproof fine mortar. Waterproof fine mortar is a small amount of "plugging king" in the mortar made of fine sand as aggregate.

The thickness of the cover is about 1-2cm. and no other measures need to be taken. Because you are using waterproof concrete, you can build it by yourself.

Specifically, it can be carried out like this: the outer surface is insulated. First, the base surface is plastered about 10mm, which is equivalent to leveling.

The thickness of the outer board varies from 50 to 100. According to local requirements. Wipe the protective sand paddle on the outside of the board, or you can paste bricks.

The bricks are applied to protect the slabs from damage when backfilling.

Do waterproof and anti-corrosion on the inner side: first plastering and leveling, as for the waterproof materials, there are more waterproof materials, waterproof sand paddles can also be used to use waterproof membranes, do a protective layer, brush hot asphalt and paste anti-corrosion materials after drying, and finally don't forget to do a good job of protective layer. Go give it a try.

No, just press JEM7727: First of all, can the sewage treatment tank be made of brick and concrete? The norm shouldn't allow it. At least it should be a reinforced concrete structure, and if you can, you can take a look at the approach of the basement in the "Zhongnan Standard Architectural Composition Atlas", because it is very similar. If you want to be more professional, go for a water supply and drainage professional. I dismantled it again.

Anyway, it's almost finished, so why not try and change it again, so as not to waste money.

It is better to do a few more glossy treatments in combination with waterproof mortar.

I asked you a friend who is a supervisor: you can use waterproof mortar without considering the cost, and if you are on the safe side, you can add a layer of waterproof agent such as BBS and other waterproof coatings.

1. If you want to do waterproof construction for the reservoir, then you should first use cement mortar with a thickness of 20mm on the inner wall of the reservoir for smoothing, or use polymer mortar for smoothing, and the surface flatness after smoothing should be within the range of 2 meters, and the allowable error is generally within 5mm. 2. The screeding layer on the inner wall of the reservoir must be kept firm and compact, and there should be no sanding, cracking and other phenomena. The surface of the treated base and balance layer should be kept flat and there should be no potholes.

Next, we should wait for the base layer to dry thoroughly, and we should ensure that there will be no oil stains, ash slag, etc. on the surface of the base layer, and the moisture content of the wax base position with an internal depth of 20mm should not exceed 6%. 3. If there will be leakage in the reservoir, then it is necessary to take a suitable method to make the paper basket first, and then do waterproofing. When the base layer is completely dry, it is also necessary to use environmentally friendly waterproof paint to apply to the inner wall of the reservoir to play a waterproof role.

1.Base surface treatment is the foundation and key to waterproof construction, in order to ensure its firmness, smooth and clean, etc., the base surface needs to be cleaned before construction, if there are gaps, cracks and other defects to be repaired and smoothed with cement mortar, the yin and yang corners should be wiped into an arc, and keep the base surface moist without clear water.

2.Apply waterproof paint. Brush the waterproofing treatment on the base layer and repeat it after drying (about 2-4 hours) to complete the waterproofing treatment.

The waterproof coating should be evenly painted, and there should be no missing brushing, bulging and burning and falling off, otherwise it will affect the waterproof random search effect.

3.After 24 hours of waterproofing construction of the pool, it is recommended to cover the coating with a damp cloth or spray water to maintain the coating, and it is forbidden to step on, rain, expose to the sun and damage from sharp objects before it is completely dry.

4.Carefully inspect when painting, especially at the joints, yin and yang angles, etc., after the construction is completed, the closed water test should be done for 24 hours, and the closed water height should be increased as much as possible, not less than 20cm, and then carefully check whether the water level has dropped and whether there is leakage.

Materials: JS waterproof coatings, cement-based permeable crystalline waterproof materials, etc., are suitable for anti-seepage, leakage-proof, waterproof and anti-corrosion of various water towers, pools, tanks, puddles and sluices. Both tap water and drinking water pools can be used.

1. If you have used the pool before, please drain all the water in the pool and give it a certain drying time.

2. Clean the surface of your pool. Use a wire brush to remove dirt, oil, or debris. If you have paint and cement paint on the surface of your pool, the surface must be removed with a paint remover or a 20-concentration hydrochloric acid solution.

Everyone should wear gloves and protective glasses when operating. After 1-4 hours thoroughly cleanse the posture and the entire area with water.

3. Repair any cracks or damaged areas if necessary. Allow any cement or other products to dry thoroughly before proceeding with waterproofing construction.

4. Please read the product description of the waterproof material you choose carefully before use. There are two different waterproofing products you can use, but be sure to check if they are compatible with each other.

5. Before applying waterproof materials, you can apply primer on the surface of the wall once, which can increase the waterproof effect of the entire pool.

6. If you choose a waterproof coating, please mix your waterproof products according to the instructions. Keep in mind that every product will be different.

7. When carrying out the first layer of waterproof construction, it is necessary to pay special attention to the edge gaps and cracks of some walls, apply as many times as possible, and ensure that all areas are covered.

8. After the first waterproofing is completely dry, you can carry out the second layer of waterproof construction of the pool, and the steps are the same as the first layer of waterproofing. Once the cure is complete, the water storage test can be performed.

Waterproofing can be achieved by applying waterproof paint to the surface of the reservoir. The compressive resistance of the waterproof coating is higher than that of traditional materials, the long-term wet immersion corrosion resistance of water, and the strong adhesion to the substrate, the active ingredients in the slurry can penetrate into the capillary pores, microcracks and chemical reactions in the cement substrate, and the substrate is integrated to form a crystalline dense waterproof layer.

Advantages of cistern waterproofing coatings:

1. Non-toxic, harmless and environmentally friendly products; It does not contain harmful substances and volatile solvents;

2. It can be constructed on a wet base surface (but there can be no stagnant water);

3. Good wear resistance, good adhesion, good adhesion between the waterproof layer and the base surface of concrete, and can be permanently combined with the underlying material to prevent water penetration;

4. After the coating is dry, other covering layers can be constructed without making a cement mortar protective layer.

Note: The reservoir should be built at an elevation of 350 700m; natural villages with relatively concentrated settlements and water difficulties; There is an area of natural water (natural rainfall) and can be constructed as a diversion ditch; The terrain is flat or there is no slip in front and back; The valley can be irrigated by artesian water; The formation is required to be dense and solid, and no water leakage; Avoid sources of pollution; Do not build ponds on the rocky cellars where scattered particles, slope deposits, landslides, and fissures develop.

<> the inside of the reservoir is waterproofed, the inner wall should be leveled first, and the 20mm thick cement mortar should be smoothed, and the error should not exceed 5mm. The screed must be compact, without cracks or sand, and without potholes. When the base layer is dry, that is, the moisture content within the thickness of 20mm cannot exceed 6%.

If there is dust or oil on the base layer, clean it up and apply waterproof material. In addition, if there is a leak in the reservoir, be sure to stop the leakage before waterproofing. Finally, it is enough to apply waterproof material to the inner wall.
