High Build Uses

High Build is an excellent choice for sealing around vents and drains, where pipes pass through concrete.
The foundation walls require a sealant that both adheres to the different materials equally well but has sufficient flexibility and elasticity to resist cracking and tearing due structural movement.

High Build is UV-resistant, meaning it can be used inside and outside and will not be damaged by the sun.
