How to maintain and increase flexibility for waterproofing construction when it? Laiwu Jinda waterproofing membrane manufacturers for everyone to do in detail: Coil softness that is a flexible membrane hypothermia is an important physical indicators modified bitumen membrane. Flexibility refers to the flexible membrane sheet subjected to bending performance at low temperatures when. Done at low temperatures, coil case of poor compliance waterproof construction can not be reckless, or in the construction of the web is very easy to crack, it's like a crack appear on the glass, as the weather warms up the crack will not heal, and form crack, this crack will inevitably cause leakage after the waterproof layer. To avoid this situation, the construction side should actively create conditions to maintain and increase the low temperature flexibility of the web as the web at the construction site on the leeward sunny place, too cold or windy days when the first do construction, etc. The weather the sun came out to open the web dispersion, so that the warmth of the sun for a while and then construction. Construction unwinding roll to the last time the core stiff, easy to crack, available blowtorch baking it, in order to improve the flexibility of the web. Where conditions permit may be placed in a warm indoor coil used with the check. Every winter the temperature drops, the cold weather every day, water projects should concentrate once you start giving surprise, grab a good weather, surprise one day is equal to dry for three days. Construction organizers must find out at what temperature the coil construction will not crack, you should choose the degree of compliance is the number of coil, it will not appear on the web crack in the construction process, in order to avoid because of the volume of exchange Dirou material cost increases. Throughout the construction, the construction side must always seasonal and climate change live coil construction temperature control flexibility and coil to avoid cracks and fissures in the web handling and transportation and construction process to ensure the quality of water works .
