Impey's innovative Aqua-Grade wetroom floor former is the perfect product to use when fitting a wetroom into a new build or extension. The design allows for it to be laid at the same time as the concrete floor and produces a perfect 1.40 gradient. You simply fit the colour coded sections of the Aqua-Grade matrix together and screed over the top. The modular construction of the matrix system means that the wetroom area can be as big or as small as necessary. It is suitable for use with insulated floors and compatible with underfloor heating systems.
