Wet the cleaned area before applying the repair material
Fill small voids and cracks using a mechanical injection pressure pump with a suitable material such as non-shrinkage epoxy grout.
If the honeycomb covers a large area, you may need to create a patch hole to ensure proper bonding.
Place formworks if necessary, and pour the grout.
If formwork is not used, apply suitable repair material such as non-shrinkage, high-strength grout.
The filling process should be in a 15 mm thickness layer if the depth of honeycombing is greater than 5 cm. It is recommended to wait for a while (30min) before applying the next layer.
Repair material strength should match the virgin concrete of the structural element.
Provide texture and color required to match the surrounding concrete and maintain aesthetics.
If present, remove formworks after 12 hours of repair based on the type of material used and ambient conditions. Cure repair material to gain adequate strength.
