servicesCar Park Refurbishment

Extending the life of your parking structure

Complete Solutions for Multi-Storey and Surface-Level Car Parks

Multi‑storey and surface‑level car parks are the unsung workhorses of our built environment.  They carry weight all day. They take rain, salt, exhaust fumes and constant vibration. Over time, those forces work their way into the structure. Concrete breaks down. Steel corrodes. Coatings fail. This is how car parks age.

Refurbishment isn’t about covering that up. It’s about rebuilding what matters, so the structure can keep working for decades to come.

At H3 Construct, we specialise in full car park refurbishment, from targeted repairs to complete structural and visual upgrades, delivered in live, operational environments across the UK. These are spaces that can’t close. Water ingress, surface wear and structural deterioration create real risks, but shutting the doors isn’t an option.

Our role is to slow failure down, restore performance and extend service life, while keeping the car park open and working the whole time.

  • Our Refurbishment Services Include:

  • Concrete repairs to decks, soffits, beams and columns

  • Crack injection and structural protection

  • Deck coating systems (including waterproofing and wear coats)

  • Expansion joint replacement

  • Anti-carbonation and protective coatings

  • Line marking and bay reconfiguration

  • Drainage improvement and ramp regrading

  • Lighting coordination and safety upgrades

The science behind our repair techniques

Concrete repairs
Decks, soffits, beams and columns carry the load. They are the structure. When concrete breaks away or steel starts to corrode, that load has nowhere safe to go. We cut back to sound material. We clean and treat the reinforcement. We rebuild with high-strength repair mortars. The aim is simple: restore continuity so the structure works as one again.

Crack injection and structural protection
Cracks are how water gets inside. Once water reaches the steel, corrosion follows. We inject low-viscosity resins to fill and bond cracks, sealing the concrete and returning it to monolithic behaviour. Where risk remains, we add corrosion inhibitors and galvanic anodes to slow the process down long after the repair is finished.

Deck coating systems
Car park floors take constant abuse. Tyres. Weather. De-icing salts. Our systems are built in layers. A primer to bond. A waterproof membrane to block water and chlorides. A wear coat designed for grip and durability. Together they act like a second skin, protecting the concrete beneath from what hits it every day.

Expansion joint replacement
Structures move. Temperature changes. Loads shift. Joints are there to absorb that movement. When they fail, water finds a direct route into the structure. We remove degraded joint systems and replace them with new mechanical and elastomeric joints, selected to suit the movement and loading of the structure. These systems are designed to stretch, compress and remain watertight while the building moves around them.

Anti-carbonation and protective coatings
Carbon dioxide changes concrete chemistry. It lowers alkalinity and leaves steel exposed. Our coatings form a barrier to carbon dioxide and water while still allowing moisture vapour to escape. The concrete stays protected without being sealed shut. Deterioration slows. Service life extends.

Line marking and bay reconfiguration
Lines fade. Layouts stop making sense. Confusion leads to damage and accidents. We resurface and re-mark bays and lanes using durable, high-visibility materials. When use changes, we redesign layouts to improve flow, safety and capacity.

Drainage improvement and ramp regrading
Standing water does damage quietly. It seeps in, freezes, thaws and accelerates failure. We improve drainage by installing new outlets, correcting falls and regrading ramps so water is pushed off the deck instead of soaking into it. Slip risks drop. Durability improves.

Lighting and safety upgrades
Visibility matters. Better lighting makes spaces safer and easier to use. We coordinate electrical upgrades, replacing outdated fittings with efficient LED systems. Where needed, we integrate CCTV, handrails and safety features to improve both security and user experience.

Refurbishing a car park while it’s open is like repairing a road without stopping traffic. The structure still has to work. Vehicles still move through it. People still rely on it. And safety can’t be compromised at any point.

Every project starts with planning. Works are broken down into phases so as many levels remain operational as possible. Areas are closed only when they need to be, and reopened as soon as it’s safe to do so. Clear work zones are established, with physical segregation that separates construction activity from live traffic and pedestrians.

Communication is constant. We coordinate closely with operators, property managers and asset owners to align programmes, manage access and respond to changing site conditions. Traffic movement, pedestrian routes and emergency access are maintained throughout, with signage and temporary measures adjusted as the works progress.

Disruption is controlled, not ignored. Dust, noise and vibration are managed through careful sequencing, method selection and specialist equipment. High-impact activities are planned around peak usage, and materials and plant are chosen to reduce disturbance wherever possible.

Whether we’re carrying out isolated patch repairs or a full-deck refurbishment, the approach stays the same. Protect the people using the space. Keep the structure functioning. Deliver the work safely, clearly and to a standard that holds up long after the site is handed back.

Testimonials

"The team at H3 are an experienced professional team able to advise, supply and install numerous products to businesses. The team spent time understanding the needs of the business and provided cost effective options for consideration. The planning of the works was good and works started and ran to the agreed timeframe. Whilst working on the site all health and safety issues were covered and the team spent time to keep the management team updated of progress. A flexible approach to working times was seen and the business was not impacted by the works. In addition no complaints were received from guests, nearby residents or other service providers during the works. The working relationship after the works were completed remained and requests for other smaller works were responded to quickly and effectivity. Overall a good value, professional company who deliver the projects on time. "
