Mapei renovation and tiling systems have been used as part of an extensive redevelopment at Gatwick Airport Station. The project, which was carried out by DMC Contracts for Costain, included construction of a new second concourse and airport entrance, doubling available space for passengers accessing the airport terminal.
Providing a “bigger, better and brighter” space, the renovated concourse is the size of eight tennis courts and has created 500sqm of extra space in the existing station concourse. The upgraded station is accessible to all passengers and includes eight additional escalators, five lifts, new stairways and widened platforms, as well as updated information areas, wide ticket gates and a dedicated passenger assistance point.
During DMC Contracts’ surface preparation, cracks in the existing concrete screed were first repaired with Mapei Eporip solvent-free epoxy adhesive. Mapeproof One Coat surface damp proof membrane was then applied, to suppress residual and construction moisture, followed by the company’s ECO Prim T Plus – described as a very low VOC universal acrylic primer. The surface was levelled with fibre-reinforced levelling and smooth compound, Mapei Ultraplan Renovation Screed 3240.
Prior to tiling, Mapetex system anti-fracture membrane was bonded to the substrate with the company’s Ultralite Rapid Flex S1 adhesive – which it calls a rapid-setting, low dust flexible, lightweight one-component adhesive.
During the final fix, Mapei adhesives were used to install the 600 x 600mm porcelain tiles: Keraquick S1 quick-setting and Keraflex Maxi S1 deformable cementitious adhesive. The tiles were then grouted with Ultracolor Plus – the company’s anti-efflorescence and mould-resistant quick-setting and drying polymer-modified grout and all perimeters, intermediate and construction joints were filled with Mapesil AC mould-resistant pure silicone sealant. g
