Abstract：
The basement waterproof work in Quzhou Times Plaza Engineering has high technical requirements, so WG-HEA impervious waterproof agent and powdered coal ash double-mixing technique is mainly adopted. Self-waterproof performance of reinforced concrete structure is used as the main waterproof technique which is supported by some auxiliary techniques, such as setting a 1.0mm-thick cement-based penetrating crystalline waterproof coating on concrete water side and adopting waterproof measures at such special positions as post-pouring belt and construction joint. Favorable waterproof effects are realized.
