Concrete Repair Bromley
Concrete Damage and Its Causes
Concrete may be known for its durability, but it’s not invincible. Over time, concrete can crack, erode, or become structurally compromised due to weather exposure, corrosion, water ingress, poor workmanship, or simply age. In Bromley, we often see damaged concrete in older housing stock, commercial properties, basements, and high-traffic areas such as driveways and external staircases.
One of the most common problems is spalling — where surface concrete breaks away, often exposing the rusting steel reinforcement beneath. This can lead to further cracking, water damage, and weakened structural integrity. At City Structural Ltd, we diagnose the cause of the damage before proposing a tailored repair method. Whether the problem stems from reinforcement corrosion, ground movement or freeze-thaw cycles, we provide durable, industry-approved solutions that not only repair the damage but help prevent it from returning. Our work is fully compliant with relevant UK structural and safety regulations.
Our Approach to Concrete Repairs in Bromley
Every property is different, and so is every repair. At City Structural Ltd, our first step is always a detailed inspection to determine what’s causing the concrete damage. We assess the depth of the cracks, the condition of the reinforcement (if exposed), and any contributing factors such as drainage or ground movement. This allows us to provide the most effective and cost-efficient solution.
We work on concrete walls, floors, balconies, steps, lintels, beams, retaining walls and more. For minor cracks, we often use specialist resins or fillers to restore the surface. For more serious damage, we carry out structural repairs using high-performance repair mortars and corrosion inhibitors. If reinforcement has been compromised, we clean, treat or replace the steel as needed. Once the area is restored, we may also apply protective coatings or waterproof sealants to help prevent further degradation. Every repair is handled with care, precision and backed by our workmanship guarantee.
Structural Crack Repairs and Injection Systems
Cracks in concrete can appear for many reasons — shrinkage, movement, poor compaction, or structural overload. While surface cracks may be purely cosmetic, deeper or spreading cracks can pose real risks to the integrity of your structure. In Bromley, we regularly repair cracked concrete in both domestic and commercial settings, using industry-approved resin and epoxy injection techniques.
These systems work by injecting specialised materials deep into the cracks, bonding the structure back together and restoring its load-bearing capacity. In some cases, we may also use steel reinforcement bars or install additional supports to strengthen the area. This method is commonly used for foundations, slabs, and walls. It’s fast, clean and highly effective. Once repaired, we smooth and restore the surface, blending it seamlessly with the surrounding concrete.
Concrete Floor Repairs and Levelling
Concrete floors can become damaged over time due to settlement, wear and tear, or moisture ingress. In Bromley homes and commercial properties, we often repair cracked or uneven floors in garages, basements, warehouses and public spaces. Damaged floors not only look poor but can present a trip hazard or compromise structural integrity if ignored.
At City Structural Ltd, we carry out detailed inspections to determine the cause of the problem, then apply the appropriate repair solution. This could involve epoxy crack repair, re-levelling with self-smoothing compounds, or rebuilding sections of the slab with high-strength concrete. For industrial settings, we use hard-wearing products designed to withstand heavy loads and foot traffic. We always aim to minimise disruption, and most floor repairs can be completed within a day or two depending on the scope. Once complete, your floor will be safe, level, and ready for use again — with lasting results you can trust.
Spalling and Reinforcement Repair
Spalling occurs when sections of concrete begin to break away, often due to corrosion of the internal steel reinforcement. As the steel rusts, it expands, causing the surrounding concrete to crack and eventually fall off. This is not only unsightly but can weaken the structure and pose a safety risk, particularly on high walls, balconies, or overhead concrete elements.
In Bromley, we see spalling most frequently in older flats, public buildings, and homes with poorly protected external concrete. Our repair process starts by removing the damaged concrete and cleaning or replacing the affected steel. We then rebuild the area using specialist repair mortars that are designed to bond tightly and last for years. Where needed, we also apply corrosion inhibitors or waterproof coatings to protect the repaired area from future exposure. The result is a durable, clean finish that restores both the strength and appearance of your concrete surfaces.

Frequently Asked Questions
Concrete damage can take many forms, and it’s important to spot the signs early to avoid more costly repairs. The most common issue is cracking — this might be surface-level or run deeper through the structure. You may also notice spalling, where flakes or chunks of concrete fall away, exposing the steel reinforcement underneath. Other signs include discolouration, uneven surfaces, damp patches, and corrosion stains, often seen as rusty streaks on concrete walls or floors. If reinforcement corrosion is present, it’s likely that the structural integrity is already being affected. In Bromley, we see many properties with external concrete staircases or balconies that suffer from weather-related damage. At City Structural Ltd, we offer full inspections to diagnose the type and severity of damage. Once we’ve assessed the issue, we’ll recommend the best course of action and provide a quote for reliable, long-lasting repair work using specialist techniques and materials.
In many cases, damaged concrete can be repaired rather than fully replaced — saving both time and money. At City Structural Ltd, we always aim to preserve the existing structure where possible. We use specialist repair mortars, crack injection resins, and reinforcement treatments to restore the strength and durability of damaged concrete. Whether it’s a cracked floor slab, a spalled column, or exposed rebar in a lintel, our approach is to fix the root cause and reinforce the affected area. Full replacement is typically only necessary if the damage is extensive or if the original structure has failed completely. In Bromley, we regularly carry out cost-effective repairs on residential and commercial buildings without the need for demolition. After a full inspection, we’ll let you know whether your concrete can be safely repaired and provide all the information you need to make an informed decision. We always aim for long-term, durable results.
Yes, concrete spalling can be dangerous if left unaddressed — especially when it involves load-bearing structures or elements like balconies, beams, or staircases. Spalling typically starts with the surface breaking away in flakes or chunks, often caused by corrosion of the steel reinforcement inside. As the steel rusts and expands, it forces the surrounding concrete to crack and break apart. Over time, this weakens the structure and can pose serious safety risks. In some cases, falling pieces of concrete also create hazards for people below. In Bromley, where we often work on multi-storey flats and older commercial buildings, spalling is a common issue. At City Structural Ltd, we treat spalling by removing loose material, cleaning and protecting the steel, and rebuilding the area with high-performance repair mortars. We recommend addressing spalling as soon as it’s noticed, before it spreads or leads to further structural damage that could become more costly to repair.
When completed correctly by professionals using high-quality materials, concrete repairs can last for decades. The key to durability is addressing both the visible damage and the root cause — whether that’s corrosion, poor drainage, water ingress, or ground movement. At City Structural Ltd, we use advanced concrete repair products designed for structural integrity, resistance to moisture, and compatibility with existing materials. We also apply protective coatings or corrosion inhibitors where needed to extend the life of the repair. In Bromley, where many buildings face weather exposure and fluctuating ground conditions, we choose repair systems that are suited to local challenges. The longevity of the repair also depends on future maintenance and environmental factors. We provide aftercare advice to help you protect the repaired area over time. All our repairs are carried out to British Standards and are backed by our workmanship guarantee, giving you complete peace of mind.
