Concrete repair cost depends on the established damage, intended outcome and site conditions. Without inspection, measured quantities, access information and agreed performance, a generic price is unreliable. Ask for a traceable breakdown and make uncertainty visible.

Main cost factors

Investigation and design may be needed before work, especially where cause or extent is uncertain. Repair quantity, access, height, traffic or facility controls, user protection and waste handling affect resources. Substrate preparation, materials, layer build-up, curing, quality checks and monitoring may also contribute. A small repair can still be costly if access is complex.

Compare on the same basis

Give bidders the same inspection data, drawings, photographs, boundaries and quantities. Request fixed costs, units, provisional sums, options, exclusions and rates for defined changes. State who measures quantities and how concealed damage is assessed. A price per square metre without depth, substrate and access says little about the total commission.

A lower total may reflect a smaller scope or fewer checks. Compare assumptions, risk allocation, maintenance and handover information as well. There is no universally best balance between initial price and service life; it depends on the asset, use and exposure. Ask which later inspections may be needed and how extra work is approved.

Ask each bidder what inspection supports quantities, what is excluded, which acceptance criteria are included and what records will be handed over. See also compare quotes and specify the scope.
