2. Self-built houses in rural areas are generally covered with a layer of asphalt. Although the cost of this water leakage repair method is very low, the waterproof effect is very poor, and the water leakage problem will appear soon, and the aging resistance is also very poor. Once the water leakage problem occurs again, it is necessary to completely eradicate the asphalt, which is very difficult to construct.
3. Although the cost of waterproofing membrane is low, it also has many shortcomings, such as poor durability, weak joint splicing and poor adhesion. If these problems are not handled properly during the construction, the roof will be hollowed out. Moreover, once the roof leaks after the waterproofing membrane is laid, it is very difficult to repair it and needs to be laid again.
4. Repair the roof with waterproof paint. This method mainly uses waterproof coating made of pure acrylic acid as raw material, which not only has good aging resistance, but also has good adhesion and permeability. It is also very convenient to repair, as long as you find the leaking place to fill the leak, you can use it for ten years.
Problems needing attention in rural housing construction
1. Don't build houses on cultivated land. The ownership of cultivated land belongs to the state collective, and individuals only have the right to use and operate, and cannot change the nature of land at will. Building houses on cultivated land without authorization will face the consequences of forced demolition.
2. No building shall be built in the water source area. In order to protect more clean water sources from pollution, the relevant departments stipulate that villagers are not allowed to build their own houses near the water sources.
3. It is forbidden to build houses in ecological protection areas. Ecological conservation areas, including cultivated land, woodland, pasture and grassland, especially farmland buildings, are not allowed.
4. No building is allowed without approval. The construction or reconstruction of homestead shall be approved by the township government before it can be started. Farmers can bring proof of homestead use, proof of household registration and construction drawings of self-built houses to the township government to submit applications.
5, are not allowed to be arbitrarily multilayer construction. In rural areas, it is necessary to invite some professional construction teams to build or renovate rural houses with more than three floors, and at the same time, it is necessary to apply to the town government for approval before construction can start, so as to strengthen the construction of new countryside and unify housing planning.
