As part of a £600 million redevelopment of Birmingham New Street Railway Station known as Gateway Plus, a Flexcrete system has been chosen to waterproof 3,000 square metres of floor areas in the Pallasades Shopping Centre which is situated above the station.
As part of Gateway Plus, the Pallasades is undergoing a major transformation to create 400,000 square feet of quality retail space in the heart of Birmingham, including a new John Lewis which will represent one of the largest department stores in the city. During the construction phase, it has been necessary to waterproof the floor areas in the retail outlets in the Pallasades Shopping Centre, to ensure there is no water damage to the underlying railway station and no inherent health and safety risks. Birmingham New Street is the primary railway station serving Birmingham and the second busiest railway station in the UK outside London.
A system based on Cemprotec E-Floor HB was specified. Cemprotec E-Floor HB is a two component epoxy and cementitious modified polymer topping which represents a major advancement in flooring technology. Designed for the waterproofing and protection of concrete floors in demanding environments, it affords excellent resistance to abrasion, water, chloride ions and aggressive chemicals. It is specially formulated to rapidly harden to form a hard-wearing and durable surface. To ensure abrasion and skid resistance, Cemprotec EF Grit was incorporated into the Cemprotec E-Floor HB and the system was completed with an application of Cemprotec Sandseal 75 – a clear, polyurethane coating to seal in the aggregate and provide a decorative surface with excellent abrasion and wearing characteristics. Cemprotec E-Floor HB is compliant with EN1504, the pan European standard for concrete repair.
