With the 723 Design swimmingpool gratings emco Bau present a unique way of covering overflow channels for a smart look and flexibility. This innovation consists of a rigid plastic cassette serving to hold tiles for moisture-exposed barefoot areas with a thickness of at least 7 mm. The choice of tiles can be made to suit the manufacturer. This product, which is suited for straight pool configurations and mitred corners, enables the covering of overflow channels with the tile material used on the pool surround, producing a harmonious and visually appealing overall look. The PVC cassette is prefabricated at the factory so that together with the tiles its dimensions are precoordinated at the factory to suit site-specific frame conditions. At the same time the grid design ensures water drainage while complying with standard bar spacing. The tiles are delivered and bonded on site by a specialist tile-layer.
