Water seeps through a wall crack under groundwater pressure.
Use the site evidence to agree a project-specific method with the responsible engineer, concrete producer, manufacturer or specialist applicator.
Water seeps through a wall crack under groundwater pressure.
Map crack width and movement; assess structural significance, water flow and external access.
A crack may carry water but also signal settlement, restraint or structural distress.
Have structural cracks assessed; use an engineered injection or external repair after identifying the mechanism.
Control active water and follow resin or grout mixing, port spacing and injection limits from the approved method.
Monitor under wet conditions and document treated length and any residual leakage.
Do not inject a moving structural crack with a rigid resin without engineering review.
