Nowadays, the society is relatively developed. Many people choose various materials when they are waterproofing. However, many roofs will leak after many years. Do you know what to do? Know the roof waterproof construction. What is the technical regulation? Next, the decoration house Xiaobian introduces the technical problems of roofing waterproof construction and the problems of roof waterproof construction. I hope everyone can refer to it when doing waterproofing.

I. Technical regulations for roof waterproof construction


1. Base treatment: The base layer should be cleaned before looking for slope construction, and there must be no construction waste and other sundries.


2. Marking production: The marking gray cake production is made according to the design slope of the drawing, and the construction is strictly carried out by using tools such as level gauge, and the allowable deviation is less than 3mm.


3. Foam ç ¼ find slope: foam ç ¼ adopts integral pouring process, layer thickness construction of more than 100mm.


4. Leveling: The screed is made of 20 thick 1:3 cement mortar. After screeding, it will be compacted and lightened in time. One machine, the second artificial iron plate receives light.


5. Detail construction treatment: the boundary between the base layer of the coil waterproof layer and the protruding roof structure, and the corner of the base layer treatment are made into a circular arc with a radius of not less than 50 mm.


6. Strengthening treatment of the flue area: the joints of the flue and the roof and the roof are made of polyethylene polypropylene high-mole waterproofing membrane and waterproof coating for the waterproofing of the base layer.


7. Structural water test: After the completion of the base treatment, the water test shall be carried out in time, with a water depth of 50 mm or more and water for 48 hours.


8. Water seepage treatment: After the water test, it was found that there was water seepage. After timely pouring and grouting, the board was made of polyethylene polypropylene polymer waterproof membrane and waterproof coating.

9. Cold base oil brushing: Evenly apply cold base oil on the base layer before laying the waterproof layer. The jade wrench is sprayed. Cold base oil application: Evenly apply cold base oil on the base layer before applying the waterproof layer. Jade wrench using sprayed square

law.


2. Problems in roof waterproof construction


1. The design unit does not pay attention to the waterproof design. The selection of the waterproof layer should be carried out by the designer in strict accordance with the "standard" requirements. This is the responsibility and obligation of the design unit. However, because many designers are not familiar with the quality of waterproof materials, they are free to set.

Use the construction atlas. The construction unit intervenes in the waterproof design, the designer abandons his responsibilities, and the selection of the waterproof material is determined by the construction unit, which leads to the loss of quality control of the building waterproofing project during the design phase.

2. The quality of building waterproof materials does not meet the quality requirements. The current basic situation of the waterproof material market is still in a situation where the fish are mixed, the good and the bad, the true and false are difficult to distinguish, the counterfeit and shoddy products are repeatedly prohibited, and there is a tendency to spread further. In particular, the leading product SBS modified bitumen waterproofing membrane is the most affected. Counterfeit products are dumped at a price lower than 60% of the regular products, and the market share is large, making it difficult for formal large and medium-sized enterprises to continue.


3. The quality control awareness of the construction unit is not strong. The proliferation of fake and shoddy waterproof materials is followed by the low cost of the waterproof engineering, making it difficult for the formal waterproof professional construction company to win the bid. On the contrary, these projects fell into the hands of low-quality contractors with unqualified and affiliated relationships, and undertake waterproof projects in the form of subcontracting and illegal subcontracting. These team members have obtained a complete "qualified" certificate. Through vigorous efforts, they can win the bids repeatedly, and then slash and reduce the materials, and employ migrant workers to work extensively. Once a leak occurs, it can be dealt with for two years with a few barrels of paint, and the profit can still be greater than the "loss" situation. The only requirement for improving the quality of construction is empty talk.


A lot of people will leak water when they build a house. The above article is about the technical problems of roofing waterproofing construction and the problems of roofing waterproof construction. Xiaobian said that it is not clear, if you want to know more For renovation information, please continue to pay attention to the decoration home network.
