PROBLEM TO BE SOLVED: To provide a concrete joint portion joint drain and sealant, which has a simple cross-sectional shape and a large deformation amount, which is easy-to-manufacture and easy-to-apply to loading work to a concrete joint portion joint, and which is capable of handling irregularities on a concrete joint portion joint wall surface and capable of forming a drain channel in the joint, and an installation method of drain and sealant in a concrete joint portion joint.SOLUTION: The concrete joint portion joint drain and sealant is a linear body formed of an elastic member. The concrete joint portion joint drain and sealant has: a cross-sectional shape formed by an outer portion including an upper face being concaved toward the central part, both sides inclined downward and a bottom; and a hollow part formed by an upper peripheral face extending generally parallel to the upper face, side peripheral surfaces inclined downward and a bottom peripheral surface. The concrete joint portion joint drain and sealant has a tongue piece of a thin wall extending outward at the respective points where the upper face and both sides cross each other the thickness of which gets thinner toward the front end. |
