Abstract
Recently, the decrease in the hydraulics function by deterioration becomes a problem in hydraulics facilities for agriculture. Authors are developing the repairing method that uses the geomembrane for the joint in the reservoir made of concrete. Unlike a past method of facing, this repairing method constructs the geomembrane only in the joint part, and it excels by decreasing the use material in the economy. However, there is a problem in performance that prevents water leak because the boundary of the geomembrane and the structure is continuously resulted in the both ends of the joint part. To solve this problem, the seal material is arranged between surface of structure and geomembranes. This paper reports on outline and result of various performance evaluations that assume demanded performance, and result of verifying influence on geomembrane by difference of seal material.
