Waterproof project is an indispensable part of family decoration, and of course villa decoration is also indispensable, so how should the villa be waterproof? Below we bring the relevant precautions for villa waterproofing on this issue.

Waterproofing of terraces and roofs:

1. The through-wall holes leading to the outdoor through pipes and flat cables shall be filled with flexible fillers and treated with flexible waterproofing;

2. The facade of the rebound beam adjacent to the floor, the wall adjacent to the floor, the floor, especially the joint between the rebound beam and the ground, the ground and the wall, should be filled with polymer cement, and painted with 2-degree waterproof coating, with a coating height of ≥300mm (but not limited to the height of the rebound beam);

3. The specifications of the floor drain used for drainage should match the required water discharge in the floor area. Floor drain installation should be slightly lower than the finished floor tile surface, and firmly sealed with the drain pipe.

4, outdoor socket should have waterproof cover, waterproof cover around the application of sealant embedded, to prevent rain from the socket through the catheter into the room;

5, floor tile shop is stuck according to 3‰ to find slope in the direction of floor drain;

6. The drain pipe of the mop pool and bucket installed on the terrace should be installed firmly to ensure that the seal is watertight;

7, using concrete frame structure, cast-in-place concrete floor slab, masonry combination will turn the balcony into an indoor room, the cement, steel, sand and stone selected should meet the quality standards, and ordinary sintered bricks should be used for masonry; Concrete pouring and vibrating should be dense and maintained according to seasonal requirements to avoid water seepage due to cracks caused by shrinkage and settlement.

8, new masonry shall not stand on the inside of the parapet or ground beam;

9. After plastering, the external wall of masonry shall be waterproof for 2 degrees with polymer cement coating.

10, the top surface of cast-in-place floor slab should have effective drainage measures, adopt the scheme of combining polymer waterproofing with coiled material waterproofing, and handle the waterproof details of interface parts and drainage pipes well.

1 1. For the settlement joint between the top surface of cast-in-place floor slab and the original floor slab, the concrete label should be stronger than the floor slab, and flexible waterproof treatment must be done.

12. If the balcony is changed into an indoor room by using a sun room with a metal structure, it shall not stand in the parapet or ground beam. The gap with the original structure should be filled with flexible materials and treated with joint waterproof sealant.

13, the connection between the column and the beam, the expansion screw of the column installed against the wall, and the glass installation should adopt waterproof sealant tape and inject weatherproof sealant for sealing treatment; For outdoor parts, silicone structural sealant is recommended for sealing and caulking waterproof treatment.

Waterproofing of toilets and kitchens;

1, floor drain, marble threshold, shower room water retaining parts should be made into radians after being embedded with polymer cement, made into buns through the nozzle of the floor, and reinforced with waterproof paint, except for necessary sealing and waterproof embedding;

2. Where there are holes, effective sealing should be done;

3, before the shop is stuck floor tile, the ground should be coated with 2 degrees waterproof coating;

4. The bathroom wall, especially the shower room area, is waterproof and turned upwards along the ground 1500mm or more, and the kitchen wall is waterproof and turned upwards along the ground by 200mm or more;

5, bathroom floor, kitchen floor finish should be lower than the marble threshold 8 ~10 mm;

6 It is forbidden to lay the washing machine drain pipe or mop pool drain pipe in parallel with the floor drain pipe. If parallel pipes must be used, a loop drain pipe with an effective distance should be made according to the displacement to ensure that the water storage height in the loop pipe is ≤ 1/2 the diameter of the drain pipe.

Basement waterproofing:

1, the basement is located below+/-0.00, which is the most permeable area, so be sure to check the waterproof quality of the original structure when entering the site;

2, metope if there is no waterproof measures or waterproof quality is unqualified, you must redo the coiled material waterproof and a cloth four coating waterproof;

3, the ground in addition to do coiled material waterproof, should also add a 4 coating waterproof on the leveling layer. If necessary, a special waterproof scheme must be prepared, which can be implemented only after approval;

4. Waterproofing of the newly-built concrete basement should be constructed in the waterfront;

5, the new basement should be set up effective drainage facilities, without acceptance shall not be covered, drainage ditch waterproof technology with basement floor waterproof.

Important note:

1 Before laying floor tiles or marble on the ground in all wet areas, a 24-hour water storage test must be carried out, and the water storage height is generally 20mm, and no leakage should be ensured.

All drainage pipes must be tested to ensure no leakage.

3 All waterproof works shall not be concealed or covered by the next working procedure without acceptance.
