WATERPROOFING METHOD OF CONCRETE STRUCTURE, CONCRETE STRUCTURE, AND WATERPROOFING AGENT FOR CONCRETE STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a waterproofing method by which waterproofing work for a concrete floor slab covered with a ballast layer is performed easily and efficiently.;SOLUTION: In the waterproofing method for the concrete structure 1 in which the concrete floor slab 2 is covered with the ballast layer 7 having the ballast 8 bedded therein, a permeation type liquid waterproofing agent 12 which is hardened under existence of calcium, or a waterproofing agent 22 which is prepared by turning the liquid waterproofing agent into a gel or by granulating the liquid waterproofing agent into the size that can enter into the gap of the ballast 8, is scattered over the ballast layer 7. The scattered waterproofing agent 12 or 22 is allowed to stay in the gap of the ballast 8, and to penetrate into a leakage place like a crack 2a or the like of the concrete floor slab 2 by using the water added to the ballast layer 7.;COPYRIGHT: (C)2006,JPO&NCIPI
