Preventative Maintenance & Care for Facility & Operations Managers in Bristol

Start with a condition survey of the concrete elements that matter: warehouse and workshop floors, external yards and car parks, ramps, steps, loading docks, retaining walls and any multi-storey car park structure. The survey should map defects such as cracking, spalling, joint damage, surface wear and rust staining, with photographs, and rank them by risk to people and to the structure. Anything that looks structural, such as cracking in beams, columns or a car park deck, or exposed and corroding reinforcement, needs an engineer's assessment.

Repairs should be specified for the cause, not just the symptom. Shrinkage cracks may only need sealing, while cracks from settlement or overloading need the cause understood first. Joint repairs in trafficked floors usually involve cutting out damaged arrises and rebuilding them with a suitable repair mortar or resin, then refilling the joint with a sealant suited to the traffic. Patch repairs to reinforced concrete need the corroded steel exposed, cleaned and protected before reinstatement, following the principles in BS EN 1504.

Car parks deserve particular attention. Water and de-icing salts penetrating a deck corrode the reinforcement over time, so waterproofing, drainage and joint seals are maintenance items rather than one-off works. Industry guidance for car park structures recommends regular inspection by an engineer, alongside routine checks by the site team for leaks, spalling and vehicle impact damage. Record the findings each time so trends can be seen, and check line markings and height restriction signs at the same time.

Working on an occupied site takes planning. Resin and mortar repairs need areas closed while they cure, and some products give off odours or need ventilation, so agree timings with occupiers and consider weekend or night work for busy floors. Ask for COSHH information for the repair products, how dust from cutting and grinding will be controlled, and how the work area will be separated from forklift and pedestrian routes. Fire escape routes need alternative arrangements while closed.

A planned programme makes budgets more predictable. Group minor repairs into regular visits, put larger works such as joint replacement or deck waterproofing into the capital plan, and link each repair to its survey reference so its performance can be tracked. Keep original construction drawings where they exist, because they show reinforcement and joint layouts, and file any product warranty paperwork with the asset records, noting its maintenance conditions.

When comparing proposals from the concrete repair contractors you are introduced to, check whether a survey comes before repairs are priced, the repair method and products for each type of defect, how areas will be closed and for how long, and how completed repairs will be recorded. Contractors who ask what caused the damage are more likely to propose repairs that last.
