| For crack of concrete in underwater |
DH-800 is a quality product, which has been developed as a solution to the unfavorable situation in which adhesive property and mechanical strength, the characteristics of the hardened substance, are drastically reduced when the moisture that has remained from the hardening process of epoxy resin causes a serious trouble to the reaction between the main material and the hardening agent. It has an excellent bonding strength with those parts of concrete structure which are soaked with water or leaking water. Being processed as a medium viscosity material, it is easy to inject if you use injection device. grouting chemical for concrete In addition, it does not shrink after hardening and maintains strong bonding strength and high mechanical strength.

It is used for the repairing of cracks of over 1mm when the measured width of a crack is larger than the allowable width in case the target member is structural member, or when the structural stability, durability, waterproof should be considered regardless of the identity of the target member. Applications are as follows.
