Concrete Slab Repair East Riding Leisure

East Riding Leisure, Bridlington is a £25 million development replacing the original building whose fabric and infrastructure was deteriorating to such a level that the ongoing maintenance requirements dictated the site was no longer sustainable as a going concern.

During construction an issue was discovered with the recently installed Sports Hall slab, with several sections of the slab requiring additional strengthening to relieve hogging stresses in excess of reinforcing bar installed in the slab.

Two options were proposed:
1) Hydro-demolish areas of the slab to a depth of 80mm, installation of new steel with a minimum of 30mm cover, and concrete reinstatement to match the existing grade strength.
2) Carbon fibre strengthening in lieu of traditional reinforcement to the top surface of the recently constructed concrete slab.

Specialist UK Restorations employed the services of Curtins Consulting to produce a series of scheme designs to suit availability/cost effectiveness of Sika products, and a detailed design of one product for use in lieu of proposed traditional H8 reinforcing bar.

We were awarded the contract due to both the cost effective nature of the proposed solution, and also the non-intrusive nature which allowed other trades to continue working throughout. The specified product was SikaWrap-301C which is a unidirectional woven carbon fibre fabric. All works were successfully complete within a 2 week window to ensure there was no impact on the critical path.
