Does the first floor need waterproofing?

Does the first floor need waterproofing?

1, if the 1 floor is a family living space, it must be waterproof, because the lower the floor, the higher the air humidity, and the furniture, electrical appliances and daily utensils are easily deformed or damaged by moisture, especially in places with high contact humidity such as balconies, kitchens and bathrooms.

2. If the 1 building is located in the courtyard, there is no need to waterproof it, just do the aproll position and determine the rainwater return ratio.

What should we pay attention to when doing indoor waterproofing:

1, do a good job in hydropower foundation engineering.

Before waterproofing indoor rooms, bathrooms and kitchens with good hydropower foundation and large water consumption, water pipes and wires should be laid on the roof, otherwise it will bring security risks, and once leakage occurs, it will be very troublesome to maintain and easy to destroy developers.

2, clean up the grassroots and metope

When the new house is waterproof, hit the ground and wall with a small hammer to see if there is any empty drum. If there is an empty drum, it should be knocked off. When waterproof, we should choose high-quality waterproof materials to ensure that the grass-roots level is clean, tidy and not peeling.

3. Make the first layer of rigid waterproof.

Try not to change the original layout when the bathroom is waterproof, and you must use the plug king to modify and repair it. Some corner roots and water pipe roots also need to be reinforced with plug kings. In addition, we should pay attention to the threshold stone of the bathroom, make a slope to prevent water from flowing back to the outside, and stick some wet stickers on the wall with fine cement mortar.

4, elastic waterproof coating as the second layer.

After dry curing of rigid waterproofing, flexible waterproofing can be done for the second time, especially for the floor of new houses. After a long time, rigid waterproof materials are prone to cracks. After using flexible waterproof twice, it has good elongation and leakage prevention.

5, closed water test is indispensable.

After indoor waterproofing is completed, a 24-hour closed water test should be conducted, and then go downstairs to see if there is any leakage. If the waterproof is unqualified, you can use it with confidence.
