Concrete Reinstatement London
Specialist Contractors for Industrial Concrete Floor Repairs in London
Why Choose Professional Concrete Reinstatement?
Industrial concrete floors deteriorate over time due to heavy traffic, impact damage, and substrate movement. Cracks, spalling, and settlement create safety hazards and operational inefficiencies that worsen when left untreated. Our concrete reinstatement services restore structural integrity through complete removal and re-pouring of damaged sections, providing a solid foundation for epoxy flooring systems or other protective coatings.
Patch repairs often fail within 12-18 months because they cannot address underlying substrate issues. Full reinstatement removes compromised concrete to a minimum depth of 100mm, ensuring the new pour bonds correctly with sound material beneath. We use steel-fibre reinforced concrete at 40N/mm² strength specification for industrial applications, achieving load-bearing capacity exceeding 50 tonnes per square metre. This approach eliminates recurring maintenance costs and provides a 25-year structural warranty.
Our concrete preparation process includes core sampling to assess existing substrate condition, identification of reinforcement positions, and structural engineering assessment where required. The new concrete specification matches your operational requirements, whether supporting racking systems, forklift traffic, or manufacturing equipment. Power-floated finishes achieve flatness tolerances of SR1 or SR2 to BS 8204-2, ready for immediate coating application.

What Does the Concrete Reinstatement Process Involve?
Reinstatement begins with careful removal of damaged concrete using diamond cutting and hydraulic breaking equipment. Our teams create clean, straight edges at minimum 100mm depth to ensure proper bonding with new material. Reinforcement inspection identifies any corroded steel requiring replacement or additional mesh installation. Exposed rebar receives anti-corrosion treatment before new concrete placement.
Formwork installation creates the template for new concrete sections. Steel edge forms maintain precise level alignment with existing floor surfaces, eliminating trip hazards at joints. We use high-quality marine ply formwork for curved sections and proprietary steel systems for standard rectangular repairs. Joint positions align with existing control joints to maintain slab movement patterns and prevent random cracking.
Concrete pouring follows strict quality protocols from batching through placement. Ready-mix delivery maintains slump consistency between 100-150mm for power-floating applications. We add steel fibres at 25-40kg per cubic metre depending on load requirements, eliminating traditional mesh installation delays. Compaction using poker vibrators removes air voids, while power-floating achieves the specified surface regularity within 24 hours of placement.
How Long Does Concrete Reinstatement Take to Cure?
Standard concrete achieves 70% design strength within 7 days and full strength at 28 days under normal curing conditions. Light pedestrian traffic is possible after 48-72 hours, with forklift access typically from day 7 onwards. Temperature significantly affects cure times, with accelerators available for projects requiring faster turnaround at additional cost.
Rapid-cure concrete formulations reduce waiting periods to 24-hour light traffic return and 72-hour full loading capacity. These specialist mixes incorporate accelerating admixtures and achieve 30N/mm² strength within 24 hours at 20°C ambient temperature. Weekend installations starting Friday evening can be traffic-ready by Monday morning, minimising operational disruption.
Curing membrane application immediately after power-floating prevents moisture loss during the critical early hydration period. This eliminates the need for wet curing and protects the surface from dust and debris. Once cured, the concrete is ready for joint sealing, primer application, and final coating installation. Our project managers provide daily progress updates and confirm traffic-ready dates based on actual site conditions.
What Preparation Is Required Before Re-Pouring?
Site preparation ensures successful concrete reinstatement through systematic assessment and substrate treatment. Core sampling at 100mm diameter reveals existing slab thickness, reinforcement configuration, and sub-base condition. This information determines removal depth, new concrete specification, and any sub-base remediation requirements. Moisture testing identifies drainage issues requiring attention before re-pouring.
Contaminated concrete requires complete removal to prevent bond failure with new material. Oil-saturated sections need excavation to full depth plus sub-base replacement with Type 1 aggregate compacted to 95% modified Proctor density. Chemical contamination from acids or solvents may require neutralisation treatment. Our assessment includes contamination testing where industrial processes have operated on the floor.
Sub-base preparation creates the foundation for long-term performance. Compaction testing confirms adequate bearing capacity, with remedial works where settlement has occurred. Damp-proof membrane installation provides moisture protection where rising damp is identified. Edge preparation at existing concrete interfaces includes primer application and bonding slurry to ensure monolithic behaviour between old and new sections.

Frequently Asked Questions
Concrete reinstatement typically costs between £80-150 per square metre depending on depth, specification, and access requirements. This includes removal of existing concrete, sub-base preparation, steel-fibre reinforced concrete at 40N/mm², and power-floated finish. Additional costs apply for contaminated concrete disposal, structural reinforcement, or rapid-cure specifications. Free site surveys provide fixed-price quotations valid for 60 days.
Yes, we specialise in phased installations that maintain operational continuity. Night shifts run 6pm-6am, weekend coverage spans Friday evening through Monday morning. Sections of 50-100m² can be completed sequentially, with barriers and signage maintaining safe working zones. Fast-cure concrete options reduce waiting periods to 24-72 hours depending on load requirements.
We specify steel-fibre reinforced concrete at 40N/mm² compressive strength as standard for industrial applications. This achieves load-bearing capacity exceeding 50 tonnes per square metre. Higher specifications available for specialist requirements including 50N/mm² for heavy manufacturing or FM1/FM2 superflat tolerances for VNA warehouses. All concrete meets BS 8500-2 exposure class requirements.
Standard concrete requires 28 days curing before epoxy application to allow adequate moisture reduction below 75% relative humidity. Rapid-cure formulations with damp-tolerant primers can reduce this to 7-14 days in optimal conditions. We conduct moisture testing to confirm coating readiness and can specify accelerated systems for time-critical projects. All new concrete is power-floated to achieve the surface profile required for coating adhesion.
All waste removal and disposal is included in our quotations. Broken concrete is transported to licensed recycling facilities for aggregate recovery. We provide waste transfer documentation for your environmental compliance records. Contaminated concrete requiring specialist disposal is identified during site survey and priced separately with appropriate hazardous waste documentation.
