grassroots Concrete Slab

Rigid polyurethane foam can be used in a variety of roofing projects . Its primary use is mainly concrete cast panels or precast concrete panels and cement mortar layer . Precast concrete plant polyurethane foam , both as a waterproof layer , but also as insulation layer ; some as one of a waterproof layer, but it is also insulation, waterproofing coating with waterproofing membrane or composite ; also waterproof coatings, waterproofing membrane, hair polyurethane foam composite of three materials together to form waterproof insulation layer . Sloping roof practice primarily in the grass on concrete foam, then in its hang watts. Both forms of roofing insulation effect is very good, but because of rigid polyurethane foam resistant to ultraviolet radiation performance is poor , the construction must be set when using stationary concrete batching plant . Flat roofing project can be combined with other waterproof material used , the rigid foam polyurethane waterproof layer disposed on the lower part of casein . From the fundamental solution to the flat roof insulation problem is in the use of rigid polyurethane foam roof structure designed using structure to find the slope , especially in-situ concrete roofing .
