The anchor sheet combines the advantages of thermoplastics (good flexibility, ductility and corrosion resistance) with the characteristics of concrete( high strength and rigidity), it can not only meet the high requirement of acid-resistance structure, but also prevent the deterioration of concrete, which can prolong the building service life, meanwhile it can prevent leakage and penetration to protect the environment ditectly. The special anchoring system is suitable for buildings under pressure, and it is widely used for pipe liners with reparable defects, such as penetration, abrasion, partial collapse, corrosion, disconnection, etc.
