How to build your own tile house to make it waterproof?

1, the basic waterproof principle of Chinese tile house, the first is the angle. If there is water on the roof, it will inevitably lead to water leakage. Therefore, the roof slope at the ridge is relatively large, about 60 degrees, so as to facilitate the rapid flow of water and slow down the angle at the eaves. At about 30 degrees, the leakage probability can be reduced by 80% by using the inertia of launching to rush out from the tiles and speeding up drainage.

2. Secondly, the waterproof layer. The rafters arranged on the roof are usually covered with a layer of wooden boards called monitoring boards to support thatched backs and tiles. Besides the wooden watch board, there are other materials, such as Jingba, Ba Wa, cushion foil, reed foil, watch brick, etc. , and make waterproof layer with marl on this layer. This operation is called thatching back. The waterproof layer shall be sealed with white ash first, then paved with blue ash similar to the concrete now, and then covered with ash 10 cm, compacted with lime and fine clay, and made rigid waterproof. There will always be leakage when tiles are superimposed, which is the second line of defense. Of course, there is also a lead-tin back similar to the current metal coil, which has better waterproof performance.

3. Finally, tile. The invention of tile is a great achievement of roof waterproofing in China, and the technological requirements for tile laying are also quite strict. Set the ditch spacing on the grey back, from bottom to top, lay dripping bricks first, and then lay them layer by layer. The dripping part should protrude 2 cm from the cornice. When laying tiles, pay attention to the fact that the upper and lower tiles are above 5 cm, usually a pair of two or a pair of three, and the gray bars should be uniform when laying tiles; When covering the pipe tile, the ash below should be enriched, so as not to overflow too much ash; Trenches should be set vertically and ridges should be straight. All ceramic tile installation should pay attention to the treatment of joints, and feel the joints are natural, smooth and beautiful. After the roof tile cover is completed, the gaps between each ridge and the pipe tile trench are evenly jointed, and the tile trench is gradually cleaned to achieve the purpose of using ash instead of ash.
