How long does chemical grout injection last?
How long does chemical grout injection last?
Once injected, cements are considered long-term solutions for either water control or structural improvement having lifespans ranging between 100 to 200 years.
What is grout injection?
Injection grouting is a process of filling the cracks, open joints, voids, or honeycombs, in concrete or masonry structural members, under pressure with a material that cures in place to produce the desired results like strengthening a structure and prevent water movement.
How is chemical grouting done?
Chemical grouting transforms granular soils into sandstone-like masses by filling the voids with low viscosity, non-particulate grout. The chemical grout is injected under pressure through the ports. The grout permeates the soil and hardens, creating a sandstone-like mass.
What is microfine cement?
MICROFINE CEMENT is a blast furnace slag-based ultrafine cement intended for specialty grouting applications.
What is underpinning a retaining wall?
Underpinning is the reinforcing of an existing building foundation. It is required when the original foundation is no longer strong enough to support the house. This is usually a result of a change to the soil structure, whether due to the type of soil or some external influence on the soil.

Why grouting is done?
What is grout and why do you need it? Grout is used as a filler for the joints between tiles once the tile you are installing has been set. it helps keep dirt and debris from getting in between and under your tile. It adds rigidity and strength to the tile installation.

- Remove grout from corners before caulking.
- Seal porous tile before grouting.
What is compaction grouting?
