With the development of China's construction technology in recent years, large span, light and high-rise buildings are increasing, so that the deformation of the roof structure has a large change, and the emergence of parking lots, sports fields, gardens and other roofs, and make the roof function greatly increased, but since the eighties, the housing leakage problem has become a very prominent problem in China's engineering construction. House leakage directly affects the function of the house and user safety. In order to solve the problem of roof leakage, WeiYiJia has carried out research work on the causes of roof leakage and treatment and maintenance methods, and is now launching the roof waterproofing gold system, which covers four products of WeiYiJia LV-305 infiltration solid sand material/LV-306 (fluorocarbon membrane) molding non-curing/LV-311 exposed repair rubber particle waterproofing material/LV-322 slate molding non-curing. It can effectively prevent the roof from leakage and re-leakage.
LV-305: with super penetration response capability.
LV-306: Fluorine resin as the main film-forming substance.
LV-311: The coating film releases moisture after sunlight exposure.
LV-305: effectively reduce tile adhesive or mortar drum delamination.
LV-306：Machining, one time forming.
LV-311: strong adhesion, do not need to remove the original waterproof layer, easy construction of complex parts.
All products meet the requirements of safety and environmental protection.
- flat roofs / pitched roofs / color steel roofs / city roof renovation
Construction environment temperature is 0 ° C ~ 50 ° C. Rain, snow, wind level 5 to. Waterproof construction should not be carried out on.
The substrate should be solid, no flimsy, sandy and uneven, no open water, oil, debris.
Through the waterproof layer of the pipeline, pre-buried parts, equipment foundations, etc. should be buried and installed before the construction of waterproof layer is completed.
The water-cement ratio must not be too large, which will easily lead to water secretion on the concrete surface and reduce the concrete surface strength.
The unreasonable grading of sand and gravel, high mud content, easily lead to the ground, mortar wall sand, affecting the early hydration of cement and the concrete set.
Do not over-vibrate during the construction process, easy to intensify the concrete surface water secretion, resulting in lower concrete surface strength.
Failure to timely maintenance or inadequate maintenance, exposure to the sun or high winds lead to a large amount of water loss on the concrete surface, the surface is not fully hydrated, resulting in lower strength.
Poor control of calendering time, concrete surface does not reach a certain strength on the human work, low-temperature construction of concrete surface frost, etc..
