Roof anti-leakage treatment method

Abstract

The invention discloses a roof anti-leakage treatment method. The method comprises the following steps of step A, forming a gas barrier layer on a roof surface; step B, installing an exhaust pipe on the gas barrier layer, and forming a vent hole communicated with the exhaust pipe in the gas barrier layer; step C, applying a waterproof coating on polyester fiberglass cloth and curing to form a bottom waterproof layer; step D, forming a surface waterproof layer in the outer side of the bottom waterproof layer; E, forming a ventilation groove in a parapet, wherein the ventilation groove is communicated to the gap formed between the gas barrier layer and the roof; step F, closing an opening of the ventilation groove. The roof anti-leakage treatment method can effectively prevent leakage, do not need to cut off original functional layers of the roof, and directly conduct construction on the current roof, thereby ensuring noise-free construction and avoiding building waste generated by roofcutting, the waterproof effect is more reliable, the construction process is environmentally friendly, and the overall cost is lower.

Description

Technical field [0001] The invention relates to a roof leakage prevention treatment method. Background technique [0002] At present, roofs (such as building roofs of substations, hotels, office buildings, etc.) are often prone to cracks after long-term use, so that rainwater often penetrates into the interior through the cracks in the roof, and cannot be discharged in time, and is hoarded in the roof. The rainwater hoarded in the roof is exposed to high temperature and the water vapor expands to cause a large number of spider web-like cracks in the fine stone concrete protective layer. The more cracks, the more rainwater hoarded in the roof. There are many water seepages in the floor. After repeated roof repairs, there are still light rain and heavy rain, and the leaking parts are gradually increasing; moreover, in the process of part of the roof leakage prevention treatment, it is necessary to remove the original functional layers of the roof , Produce more construction waste....

AI Technical Summary

Problems solved by technology

[0002] At present, roofs (such as substations, hotels, office buildings and other building roofs) are often prone to cracks after long-term use, so that rainwater often easily penetrates into the interior through the cracks in the roof, but cannot be discharged in time, and is stored in the roof

The rainwater accumulated in the roof is exposed to high temperature, and the water vapor expands, causing a large number of spider web cracks in the fine stone concrete protective layer. The more cracks, the more rainwater accumulated in the roof. There is water seepage in many places on the floor. After many roof repairs, there are still light rain and small leaks, heavy rain and big leaks, and the number of leaks gradually increases; moreover, in the process of anti-seepage treatment of some roofs, the original functional layers of the roof need to be chiseled , resulting in more construction waste
