Crack Injection

What is Crack Injection?

Specialist Polyurethane (PU) injection resins can seal water leaks with high hydrostatic pressure or flow. These resins can also be used against high or low water-bearing joints and cracks in concrete structures and below-ground construction. Our experienced teams have successfully sealed leaks with low pressure resin injection in various RC structures including basement RC walls and floors, Construction joints, RC decks, Car Parks, Culverts, Tunnels and Bridge Decks.

When is Crack Injection required?

Crack injection is required when there are cracks in concrete or masonry structures that need to be sealed and repaired. These cracks can result from various factors such as structural movement, settlement, moisture infiltration, or wear and tear. The need for crack injection typically arises when these cracks compromise the structural integrity, create water infiltration points, or present safety hazards. It is an effective method to prevent further damage, reinforce the structure, and ensure the longevity and reliability of the building or infrastructure. Crack injection is particularly important in construction, renovation, and maintenance projects to maintain the structural soundness of concrete and masonry components.


How do I know if I need Crack Injection?

Determining the need for crack injection involves assessing the condition of concrete or masonry structures. Signs that may indicate a requirement for crack injection include the presence of visible cracks in these materials, especially if the cracks are extensive, deep, or widening. Additionally, if there is evidence of moisture infiltration through the cracks, or if the cracks compromise the structural integrity and stability of the building, then crack injection is often necessary.

It’s advisable to consult with professionals like Shield Preservation who can assess the extent of the damage and recommend crack injection as a means to seal and reinforce the affected areas, preventing further structural deterioration and ensuring the long-term integrity of the structure.
