Sovereign has been dedicated to the field of water proofing since 1972. The first patents to the unique grout system were lodge in 1974. Ongoing research resulted in several grout materials and processes been developed over the years – Scem 66, Waterstop, P100, P200 and ultimately our radiation tolerant grouts - NOH2O and NOH3O.
Sovereign grouts were developed for the use in the mining industry in South Africa, but have since been utilized worldwide.
