APB has many years of experience in concrete repairs, using a range of technique and materials. These works include the removal and breaking out of a defective concrete area and the use of a proprietary cementitious mortar or concrete is applied to reinstate a structural member.
Our skilled labour force has experience performing repairs to both railway and highway bridge structures. Concrete repairs are independently inspected and verified and we are able to work to Network Rail standards.

APB undertake brickwork repairs in tunnels during possessions over weekends and mid-week nights. Brickwork replacement to the arch intrados are undertaken and temporary works put in place to secure the brickwork in place until the next available opportunity to continue with the repairs.
When undertaking brickwork repairs to structures such as Peover Viaduct, badly deteriorating brickwork is recased to pier faces, arch soffits and spandrel walls using bricks selected to match existing and approved by English Heritage. All larger repairs were carried out by sequentially breaking out and repairing on a hit and miss basis to ensure the viaducts structural integrity is maintained.
