When designing the falls across paving, it is necessary to look at the path that the surface water will follow. Roadstone’s Channel block is the solution. With the coordinating face size of 200 x 200mm and a depth of 70mm, it is ideal to meet your needs.
The 10mm deep dish in the face of the channel block is sufficient to carry the water to the drainage point without creating a trip hazard. As the Channel block is available in standard colours, there is a colour to blend or contrast with your design requirements.
