Composite waterproof layer and construction method thereof

Abstract

The invention relates to a composite waterproof layer and a construction method thereof, belonging to the technical field of construction process waterproofing work. The construction method comprises the following steps of: firstly coating a rigid waterproof coating on the surface of a basement layer; under the condition that the rigid waterproof coating is wet and uncured, covering a reinforcingrib layer on the surface of the rigid waterproof coating; and finally coating an elastic waterproof coating on the surface of the reinforcing rib layer under the condition that the rigid waterproof coating is wet and uncured, thus complete sealing is realized. The invention has the beneficial effects that the composite waterproof layer formed by adopting the construction method provided by the invention has high evenness, no lap joint, low requirement to the surface of the basement layer and good integral waterproofness, and no water channelling is caused.

Description

technical field [0001] The invention belongs to the technical field of construction process waterproof treatment, and in particular relates to a composite waterproof layer and a construction method of the composite waterproof layer. Background technique [0002] In the field of construction, waterproof measures are taken from building materials and structures to prevent water from penetrating certain parts of the building. At present, people generally take the measure of coating waterproof paint or waterproof coiled material on the base surface. For the base layer with complex shape, multi-piece splicing is required. It is difficult to bond the overlapping joints, and it is difficult to completely and absolutely seal, and there is a great risk of water leakage. The bonding between the waterproof membrane and the base layer, whether it is full paving, point paving, strip paving, or empty paving, is very easy to become a water channeling layer between the membrane and the bas...

AI Technical Summary

Problems solved by technology

At present, people generally take the measure of coating waterproof paint or waterproof coiled material on the base surface. For the base layer with complex shape, multi-piece splicing is required, and the bonding of overlapping joints is difficult, and it is difficult to completely and absolutely seal, and the hidden danger of water leakage is great.

The bonding between the waterproof membrane and the base layer, whether it is full paving, point paving, strip paving, or empty paving, is very easy to become a water channeling layer between the membrane and the base layer. Once there is penetrating damage, degumming, glue leakage, the entire waterproof layer All waterproof functions will be lost, and maintenance is very difficult

[0003] The advantage of waterproof coating is that the construction is convenient and simple, there is no overlap in the waterproof layer, and the area where the coil cannot be applied, especially the complicated parts, can be perfectly solved by the coating, and the waterproof integrity is good, but the disadvantage is the flatness of the base surface. Higher, affected by the unevenness of the base surface, it is easy to be uneven in thickness, and the thickness is determined according to the number of coating times during construction
