How to solve the leakage of the caisson in the bathroom

Water leaks in the house affect the quality of life of every household, whether it is a leak in the kitchen, bathroom, living room or basement. Kitchen, bathroom is the current home decoration process need to do waterproofing place, is also more likely to have problems in the place, if the waterproof treatment is improper, after the completion of the decoration found that the leakage is found to find a way to deal with, then the decoration layer needs to be chiseled off and redone waterproof, not only troublesome, but also the cost is also very high, time-consuming and laborious.

1. Bathroom waterproof material selection:

Waterproof coating is the first choice for waterproof construction in kitchens and bathrooms, and waterproof membranes can be used on roofs, but not in bathrooms. At present, there are two categories of waterproof materials on the market: one is polyurethane waterproof coating; The other type is polymer cement-based waterproof coatings.

The effect of both coatings is very good, the polyurethane waterproof coating used for bathroom waterproofing is best to use environmentally friendly one-component water-curing pure polyurethane waterproof coating, two-component polyurethane waterproof coating is cheap, but not environmentally friendly, it is not recommended to use. Polymer cement-based waterproof coating is also good, but because it is a two-component material, the requirements for construction are higher, and the polymerized cement-based waterproof coating on the market is also uneven, although the price of materials from some manufacturers is very low, but the quality can not be guaranteed after completion, it is recommended to buy some materials from big brand manufacturers. For example, CQ104 one-component moisture-curing pure polyurethane waterproof coating of "Qinglong brand", CQ108 high-elasticity polymer cement-based waterproof coating (K11), etc.

2. Toilet waterproof practice process:

, water storage test:

Before the construction of the waterproof layer of the bathroom, all the sewers of the bathroom are blocked, and the bathroom without caissons is built with a 25cm high barrier at the door, and then 20cm high water is poured into the bathroom, and the bathroom with caissons is directly filled with water. After 24 hours, check whether there is leakage on the surrounding walls and ground, and it is best to contact the property company and the owner downstairs, go to the downstairs owner's house to see if there is leakage, if there is leakage, it needs to be repaired in time (please be treated by professional grouting), and then do a 24-hour water test without leakage before entering the next stage of construction.

You have to see what causes the water leakage, to find the leakage point, if there are cracks in the structural plate, you need to use the high-pressure grouting method to repair the cracks first, generally 70 100 yuan 1 meter such a price.

Redo the waterproof --- closed water test - backfill after making sure it doesn't leak - it's already good, still leaking? Lay good quality non-leakage tiles, do a good job of floor drains, and have water to let it drain from the floor.

If there are cracks, the cracks should be treated first and then waterproofed, and the filler should be filled with lightweight materials such as ceramsite. If it leaks again, you and I will vomit blood.

It may be that there are cracks in the settlement joints, collect a little water, but not too much, although the landlord has done waterproofing, but not in place, if you want to do a thorough job, only to knock off the floor tiles, redo a house waterproof, only do waterproof is not more than a thousand, but after doing a good job, but also to decorate, may be more than a thousand
