Abstract：This paper introduces the application of FQY waterproofing system solution in the underground waterproofing project of a residential building. The self-waterproof part of the structure adopts the technology of preparing shrinkage-compensating concrete with magnesium high performance concrete crack resistant agent，and polymer cement waterproof coating is used for external waterproof of main structure，and the detailed nodes adopt additional layer strengthening treatment. Engineering practice shows that using the perfect FQY waterproof system solution can greatly reduce the risk of cracking and leakage of underground engineering，realize the structural self-waterproof of underground engineering，shorten the construction period and save the cost.
