Holes have been drilled from 80-100mm centre to the centre of the holes. After drilling the holes, we clean the holes by spraying them in the centre with clean water to soak them. Also, for this reason, our injection product could spread better and have a better effect during deeper penetration into the centre and on the sides of the holes.

During our work on other premises, the client asked us to check the Vault because there are visible traces of wet stains and dampness in the walls built of wooden frames and plasterboard by earlier Contractors.
The method by earlier Contractors was poorly selected and refined because wood is not used in places exposed to water such as Vault, Basement, and Cellar.
