Crack Injection
Injection of cracks in concrete structures has been performed using chemical grouts for over many years. These materials react with water so draining the tanks is not required. The chemical grouts used for crack injection are a flexible material which allows the cracks to maintain movement.
Advantages over Other Methods
1. Tank can remain in service and full.
2. Material reacts with water so unlike epoxy drying the crack is not required.
3. Material remains flexible.
Selecting A Chemical Grout
Selecting a resin may be confusing because of the selections available, not one product can solve all repairs.
