摘　　要：基于SikaProof A+12卷材的预铺反粘防水系统是一种适用于地下工程的新型防水系统,由SikaProof A+12卷材、止水系统、预埋注浆系统等组成。系统防水主材SikaProof A+12卷材由两层组成,即底层的FPO防水层(TPO膜)与表层的聚合物改性水泥粘结层。本文介绍了SikaProof A+12卷材预铺反粘防水系统的特点和在卡塔尔格湾岛项目7万多m;地下筏板基础防水中的应用。The pre-laid reverse adhering waterproofing system based on Sikaproof A +12 membrane is a new waterproofing system suitable for underground engineering,which is composed of Sikaproof A +12 membrane,water stop system,embedded grouting system etc.Sikaproof A +12 membrane,the main waterproofing material of the system,is composed of two layers,namely,FPO waterproofing layer(TPO film) at the bottom and polymer modified cement bonding layer at the surface.This paper introduces the characteristics of pre-laid reverse adhering waterproofing system of Sikaproof A +12 membrane and its application in the waterproofing of more than 70 000 m;underground raft foundation of Gewan Island Project in Qatar.
