PROBLEM TO BE SOLVED: To provide a concrete joint structure that exerts more excellent waterproof performance (cut-off performance).SOLUTION: A seepage control sheet 4 with water expansibility is sandwiched between joint end surfaces 1a and 2a of adjacent concrete members 1 and 2. Or, a cut-off material with water expansibility is injected between the joint end surfaces 1a and 2a of the adjacent concrete members 1 and 2.SELECTED DRAWING: Figure 1 |
