The invention relates to a building waterproof construction method, in particular to a roof, basement outer wall and basement roof waterproof construction method.
Background
At present, various large design houses adopt related methods in a 16CJ40-14 building waterproof system and a 10J301 underground building waterproof structure mainly for roof building waterproof methods, basement outer wall waterproof methods and basement roof waterproof methods.

And (3) carrying out: the 130-thick C30 fine stone concrete is internally matched with three-level steel phi 8@150 steel bars, and the separation joint is not more than 6mX6 m; laying asphalt felt empty; modified asphalt waterproof coiled material with thickness of 4mm for roads and bridges; 1.2mm thick high polymer modified asphalt waterproof coating; 15, 1:2.5 of cement mortar leveling layer; a reinforced concrete floor.
And 4, carrying out: a C20 fine-stone concrete protective layer with the thickness of 40mm, and phi 4@200 steel bars are matched in the protective layer; 10 thick low grade cement mortar isolation layer; one step of SBS modified asphalt waterproof coiled material with the thickness of 4 mm; 1:2.5 cement mortar leveling layer with the thickness of 20 mm; a rock wool heat-insulating layer with the thickness of 100 mm; a polyurethane coating vapour barrier layer with the thickness of 1.2 mm; 1:3 cement mortar leveling layer with the thickness of 20 mm; a reinforced concrete floor.
Secondly, basement exterior wall waterproofing (16 CJ40-7 pages or 10J 301-exterior wall 1 a-F2-3), and all the working procedures are from outside to inside
The method of the 1 st method is characterized in that the external patch is externally prevented: 2:8, ramming the lime soil layer by layer; the material and thickness of the protective layer or the heat-insulating layer are designed; a waterproof layer of coiled material; 1:2.5 cement mortar leveling layer with the thickness of 20 mm; waterproof reinforced concrete outer wall.
The 2 nd method comprises the following steps: placing outside and sticking inside: a retaining wall; leveling layer; a waterproof layer of coiled material; or 20-thick 1:2.5 cement mortar leveling layer; waterproof concrete outer wall.
Thirdly, waterproof method for basement roof (16 CJ40-23 pages or 10J 301), comprising the steps of from top to bottom
The method comprises the following steps: a protective layer; an isolation layer; waterproof layer of coiled material or waterproof paint; 20, 1:2.5 of cement mortar leveling layer; waterproof concrete roof.

And (3) carrying out: a protective layer; an isolation layer; waterproof layer of coiled material or waterproof paint; a cement-based capillary crystalline waterproof coating; waterproof concrete roof.
However, when the construction is finished according to the method, leakage of individual parts of the roof and the basement frequently occurs in different degrees, and great adverse effects are caused on later repair and rework and the use problems of the building. We carefully study and find that, the problem of building waterproof practice in an atlas and each design institute does not exist, but depends on whether the operation of each process worker is proper, the quality of responsibility center of the worker, the material characteristics, the construction quality, the maintenance condition of each process, the natural condition and other factors on one hand, and the problem of building water seepage and water leakage can be caused when a problem occurs in one link in the practice, so that the key to solve the problem is to eliminate uncertain factors brought by each intermediate process link to the maximum extent.
It can be summarized from the atlas 16CJ40-14 construction waterproofing system, 10J 301-underground construction waterproofing construction and design institute practices:
the method comprises the following steps that 1, whether the method for the water proofing of the positive roof or the method for the water proofing of the inverted roof is adopted, the method can be unified into the steps that a leveling layer or a slope layer is made on a waterproof concrete top plate, and then waterproof layer construction is carried out, wherein the waterproof layer construction is divided into a strip spreading method, a full spreading method and a point bonding method;
2, the basement exterior wall waterproofing method can be unified into that waterproof construction is carried out after waterproof coiled materials are directly paved or leveling layers are made on the outer sides of waterproof concrete exterior walls;
and 3, the waterproof methods of the basement top plate can be unified into two methods, and 1, a leveling layer is made on the waterproof concrete top plate and a waterproof coiled material or waterproof coating is made on the waterproof concrete top plate. (2) The waterproof concrete top plate is used as a cement-based capillary crystalline waterproof coating and then is used as a waterproof coating or a waterproof coiled material.
The reason for the leakage of the conventional waterproofing practice is:
1, from the structural analysis, the roof concrete roof plate is allowed to work with cracks, the waterproof layer construction method comprises a strip laying method, a full laying method and a point bonding method, no matter which construction method, the whole waterproof layer is difficult to ensure to have no wire gap by 100% according to the randomness of the existing manual construction, and the wire gap is also the root cause of the existing roof waterproof leakage, so the waterproof control key is to control the engineering quality of the concrete and reduce the possibility of the cracks, and control the construction quality of each process of a mortar leveling layer, a slope finding layer and the waterproof layer between the concrete and the waterproof layer, the mortar leveling layer and other layers have no waterproof capability, and even if the waterproof mortar is adopted, the waterproof capability of the waterproof mortar is greatly reduced under the influence of manual factors, weather reasons and the drying shrinkage of the mortar material in the whole large-area construction process, once the waterproof layer leaks, water can find the weakness of the leveling layer or the leveling layer, and the weakness reaches the waterproof concrete top plate and leaks from the crack of the concrete top plate, so that the leakage point of the waterproof layer is difficult to accurately find once the existing roof waterproof method leaks.
2, aiming at the basement outer wall waterproof method, the waterproof layer and the leveling layer are subjected to the randomness of manual operation, the characteristics of materials, the environment and other factors, the integrity of the whole waterproof layer is difficult to guarantee, the outer wall waterproof concrete is allowed to work with cracks, the outer wall is influenced by the through-wall screws and other factors, the cracks are more, the main factors are outer wall leakage, and the reason for accurately finding the leakage point of the waterproof layer is difficult to find.
3, directly making a leveling layer on the waterproof concrete of the roof plate of the basement and then making a waterproof coiled material or waterproof coating, so that the roof plate of the roof and the outer wall of the basement have the same waterproof leakage condition; when the waterproof concrete roof is used for cement-based capillary crystalline waterproofing and then is used for waterproof coating, a base film is formed on the surface of concrete, the waterproof capability of the concrete is improved, but the cement-based capillary crystalline waterproof coating belongs to rigid waterproof coating and has small deformation, the waterproof effect can be influenced if a large crack exists in the concrete, and particularly the influence of environmental factors is large in the construction process, so that the waterproof coating is easy to lose water and generate cracks. Simultaneously basement roof upper portion pipe network is numerous, and when meetting the steel pipe and wearing the roof, the waterproof requirement of two kinds of different material matrixs can't be satisfied to cement base infiltration crystallization waterproof coating, so need find the better waterproof material of another material and solve.
Therefore, the known waterproof construction methods for roofs, outer walls of basements and roofs of basements have various inconveniences and problems.
