Method Of Double Layer Membrane Waterproofing For Foundation Feb 22, 2018

Method of Double Layer Membrane Waterproofing for Foundation

Due to 100㎜ thickness of C15 concrete cushion is a non-structural system, and the waterproof layer is flexible material between the bottom plate and the reinforced concrete structures which is the weak interlayer, so 100 ㎜ thickness of concrete cushion under the loads of the unit structure lead to cracks, waterproof layer if closely bonded on the cushion layer is easy to "crack reflection" damage;Therefore, the 2008 edition of the technical specification for the waterproof of underground works (GB50108-2008,List of 4.3.16) stipulates that the flexible waterproof rolling material should be used in the bottom plate with "empty paving method or point sticking method".
