Concrete Repair and Restoration

The engineer defines initial limits from survey, sounding, cracks, corrosion indicators, and structural analysis. Harrowgate exposes the area, then sounds and inspects the open substrate and reinforcement. Removal expands where unsound concrete, active corrosion, inadequate clearance, or fractured edges continue beyond the mark, with revised quantities documented before repair placement.

Structural repair restores load transfer, section, reinforcement, anchorage, or durability essential to member performance. Cosmetic repair addresses appearance without carrying a structural role. Harrowgate treats uncertain cracks, spalls, exposed steel, and deflection as engineering questions first, then executes the approved preparation, material, reinforcement, and acceptance requirements.

The engineer sets allowable section loss and treatment. Harrowgate removes concrete as detailed, cleans the bar for inspection, measures significant loss, and installs supplemental or replacement steel when directed. Simply coating heavily corroded reinforcement without restoring required area, development, and sound concrete around it does not restore the member.

Hydrodemolition is useful where selective removal, preservation of reinforcing, reduced vibration, and a rough bond surface are priorities, such as decks and large overlays. It requires water supply, containment, wastewater management, shielding, access, and a removal plan. Harrowgate selects it with the engineer where those conditions and quantities justify the method.

Perimeter cracking can result from continued corrosion, restrained shrinkage, incompatible stiffness, shallow feather edges, poor bond, thermal movement, or inadequate curing. Harrowgate removes to defined geometry, resolves reinforcement and contamination, selects compatible material, prepares the substrate, consolidates fully, and maintains cure to reduce those stresses.

Return depends on repair-material strength gain, bond, cure temperature, member loading, shoring, coating or membrane cure, joint sealant cure, and engineer criteria. Harrowgate tracks batch and test data, protects the zone, and opens it in stages for pedestrian, light, or heavy traffic only when the applicable requirements are met.

Yes. Harrowgate phases isolation, shoring, scanning, removal, dust or water containment, material handling, cure, and reopening around production. The plan protects utilities and products, maintains required access, controls vibration and contaminants, and sets clear hold points so operating pressure does not conceal an unresolved structural or durability condition.
