DEVELOPMENT OF BEFOREHAND ATTACHED WATERPROOFING SHEET HAVING CHEMICAL ADHESIVE STRENGTH

Abstract

New water proofing sheet for underground construction such as subways was developed. Special ethylene-vinyl acetate co-polymer was applied to this new sheet which shows excellent chemical adhesion to cement matrixes.
This sheet should be stuck to the base wall before constructing buildings. Even if underground water comes into the base wall, water leakage into the building scarcely occur because of the strong adhesion between the sheet and concrete wall of the building.
