COMPLEX WATERPROOFING METHOD

摘要

The present invention relates to a two sides attached joint reinforcement type complex waterproofing method in which a detached state between a joint and a foundation surface is maintained and the joint between the waterproof sheets has a two sides attachment form for maintaining a stably attached state to waterproof sheets on both sides. The movement influence caused by a concrete structure or the influence on mutually different thermal expansion or contraction of concrete and polyurethane membrane waterproof materials are fundamentally prevented in a structure of a waterproof layer constructed with this construction method. The present invention also efficiently prevents the joint from being fractured. Therefore, the present invention efficiently suppresses that the edge of the waterproof sheet is torn or detached from the foundation surface due to the fracture of the joint. The two sides attached joint reinforcement type complex waterproofing method can obtain fundamental insulation performance without additional insulation construction as the insulation performance is improved on the whole waterproof layer with constructive properties of the waterproof sheet and a nonwoven fabric blocking the attachment between the joint and the foundation surface.
