MULTILAYER COMPOSITE WATERPROOFING METHOD

摘要

PURPOSE: A multilayer composite waterproofing method is provided to extend the waterproofing period of a concrete structure by improving durability by heightening compressive strength and tensile strength and to improve the waterproofing effect of a concrete structure by restraining a crack in the construction plane. CONSTITUTION: The multilayer composite waterproofing method comprises the steps of: applying waterproofing materials having a permeable waterproofing function such as primer using epoxy as the main component to the appointed thickness(S); applying primary ultra-lightweight mortar which has a waterproofing function and is formed by mixing cement and lightweight aggregate in the appointed ratio on the primer to a thickness of 1.0¯2.0 millimeters(M1); piling up carbon fiber on the primary ultra-lightweight mortar to restrain a crack in the construction plane(I); applying secondary ultra-lightweight mortar on the carbon fiber to a thickness of 1.0¯2.0 millimeters(M2); and applying surface coating agent such as silestone top coat on the secondary ultra-lightweight mortar to a thickness of 0.08¯0.1 millimeters to make the exposed surface smooth(E).
