Leakmaster LV-Z is a single component water-swelling sealant with excellent and unique properties. Its development was based on C.I. Takiron technology and long experience in waterswelling sealants. Leakmaster may be applied in locations where conventional solid sealants cannot be easily applied. This includes irregular shaped joints, rough surfaces, odd penetrations, etc. After curing, Leakmaster has excellent physical properties. The rubber-like elasticity of the material and expansion characteristics create an effective watertight seal.
