Born as Japan's first plastic molding expansion joint material! Molding expansion joint material "Krakutite".
The material used to prevent cracking due to the shrinkage of protective concrete is molded expansion joint material. The "Cracktight" series from Archiyamade was born in 1967 as the first plastic molded expansion joint material in Japan. The main body of the joint uses polyethylene foam, which has excellent recovery power and can sufficiently absorb the movements caused by the expansion and contraction of the protective concrete layer. We take pride in our lineup that accurately meets diverse user needs. For more details, please request our materials.
