WATER REACTION TYPE NON EXPOSURE MULTIWATER PROOF LAYER FOR TOP-DOWN CONSTRUCTION AND THE METHOD THEREOF

摘要

PURPOSE: A composite waterproof material using a water-reactive elastic coating material for top-down construction is provided to improve waterproof properties and construction performance by forming a waterproof layer using the material. CONSTITUTION: A composite waterproof material using a water-reactive elastic coating material for top-down construction comprises an HDPE sheet, a rubberized asphalt coating material, a nonwoven fabric, and a water-reactive elastic coating material. The HDPE sheet is installed on the top of a concrete surface and protects a waterproof layer from external shock. The rubberized asphalt coating material is integrally arranged on the top of the HDPE sheet and prevents deterioration caused by the acid and alkali of concrete and soil. The nonwoven fabric is integrally arranged on the top of the rubberized asphalt coating material. The water-reactive elastic coating material is loaded on the top of the nonwoven fabric and secures adhesive force.
