I.Preface
The wet laid self-adhesive rubber asphalt coiled material waterproof system uses the base material with the best water tightness - rubber self-adhesive asphalt and the lowest cheap and environmentally friendly adhesive - cement slurry to build the most reliable and economical " skin type" waterproof system.
II. characteristics of construction methods
1. new materials and innovative ideas
Self-adhesive rubber asphalt waterproofing membrane is a composite double-sided self-adhesive waterproofing membrane.Its unique bonding mechanism makes the waterproof layer like the " skin" ( skin type waterproof theory ) growing on the concrete of the building structure. the " wound" of the skin is consistent with the stabbing pain of the " body" and can be " wrapped up" calmly and simply.
2. simple process and reliable operation
The construction technology is simple and clear, the real bonding process is not artificial, it is easy to control the construction quality, and the new workers can do it with a little training.While the cement slurry ( or cement mortar ) used as the bonding layer during wet paving can be fully maintained without losing water, thus improving its compactness and crack resistance. it can play a role of rigid waterproof and can be called " one layer of waterproof, two lines of defense".
3. reduce working procedures and save time limit for a project
The traditional hot melt construction of modified asphalt coiled material requires high dryness of the base surface ( the moisture content of the base layer is less than or equal to 9 %, otherwise large-area bubbling will occur in a short period of time ). the construction period is greatly influenced by the weather.Floor, roof and other plane construction usually need special leveling layer.
The self-adhesive rubber asphalt waterproofing membrane can be directly constructed on a wet base surface, is not restricted by the moisture content of the base layer, is hardly affected by the weather, and has obvious effect of saving the construction period.No special leveling layer is needed for the construction of exterior wall and roof, and the construction of the bottom plate can be started after the concrete cushion layer is poured and people can walk.After the floor coil is constructed, it is not necessary to make a fine stone concrete protective layer, just like saving a leveling layer, thus reducing the working procedure and saving the construction period.
4. good waterproof effect and long service life
At present, high-quality waterproof coiled materials with various characteristics, such as PVC, SBS, app and the like, which are widely used in underground waterproof engineering of buildings achieve the purpose of waterproof through wrapping the structure, like putting on a " raincoat" to the structure. once the waterproof layer is damaged, water will enter between the waterproof layer and the structure from the damaged point and spread to the periphery, forming a phenomenon of " water breakthrough". it is very difficult to find and leak stoppage of the leakage point, which will result in the overall failure of the waterproof layer in the basement of buildings when it is serious.
The self-adhesive rubber asphalt coiled material waterproof layer is fully adhered to the main structure, thus improving the reliability of the waterproof layer.Even if the coiled material is partially destroyed, the water will be limited to a very small range and will not leak under the condition that the concrete of the main structure is dense.At the same time, because the overlapping and bonding of the coiled materials are the same type of self-adhesive materials, they are resistant to groundwater immersion for a long time and have a long effective life.
III. scope of application
The wet laying construction method of self-adhesive rubber asphalt waterproofing membrane basement is suitable for waterproofing projects such as basements, underground garages, civil air defence works and the like of industrial and civil buildings.
