Grout erodes in wet joints or cracks along edges.
Use the site evidence to agree a project-specific method with the responsible engineer, concrete producer, manufacturer or specialist applicator.
Grout erodes in wet joints or cracks along edges.
Check movement, joint width, chemical cleaning, cure and water entry behind tile.
Rigid grout at movement joints or incompatible grout can fail repeatedly.
Restore movement joints with suitable sealant and use grout matched to exposure elsewhere.
Clean joints fully, mix to prescribed ratio and protect curing grout.
Inspect after service cycles and confirm no concealed leak persists.
Grout replacement is not a waterproofing repair if the substrate membrane failed.
