Long-Term Waterproofing Properties and Recovery Effect by the Maintenance Using Cover Method of Acrylic Rubber-Type Waterproofing Membrane for Exterior Wall

Abstract

As a technique to realize the extension of life of the building, there are the waterproofing of the exterior wall and the protection of the structural skeleton by the acrylic rubber-type waterproofing membrane for exterior wall. The high-durable and high-elasticity acrylic-rubber type waterproofing membrane of the approximately 1mm thickness to fit for exterior wall of JIS A 6021(Liquid-applied compounds for waterproofing membrane coating of buildings) cuts off the water, carbon dioxide, chloride ion and oxygen which is a deterioration factor while following an expansion and contraction repetition movement on the crack of concrete. In this report, I grasped the long-term waterproofing performance until 35 years after application of the acrylic rubber-type waterproofing membrane and clarified the superior durability.
