This method could be carried out the place the hundreds in the foundation must transferred to strata Positioned in a length greater than 5m. This method is adaptable for seawall repair soil which has variable character, accessibility is restrictive and triggers environmental air pollution challenges.
As these particularly slim, hydrophobic resins that we use for our Specific Grout Injection react with moisture when pushed in to the soil to variety a rock-really hard, watertight mass, this remarkable repair technique removes the need for just about any digging or excavation.
