Compound waterproof system and construction technology thereof

The invention relates to a compound waterproof system and a construction technology thereof. The compound waterproof system comprises an inner base layer, a compound waterproof layer and an outside protective layer, wherein the inner base layer is formed by a non-solidifying waterproof gluing which has double features that the non-solidifying waterproof gluing is in a solid state after contacting with air at normal temperature and a flexible glue bonding state can be kept under sealed anaerobic conditions, the compound waterproof layer is formed by an outer strengthening layer formed by a high-performance synthetic rubber asphalt waterproof roll material composed of an upper covering layer, a lower covering layer and a middle modified asphalt gluing layer, and the outside protective layer is composed of polyethylene film or non-woven fabrics and fine stone concrete and steel bar mesh. The non-solidifying waterproof gluing is directly coated on a base surface, the waterproof roll material is covered and glued on the outer surface of the inner base layer, and the edge contacting parts and the surrounding edge parts of the waterproof roll material are all coated and sealed by the non-solidifying waterproof gluing so that the whole inner of the compound waterproof layer is in a sealed state. Adopting the setup of clod construction, the compound waterproof system has the advantages of reasonable components, scientific structure and reliable construction technology, reaches active technique effects of long-time no leakage for buildings, and has very strong practical applicability and commendable market application prospect.
