This product is designed as an easy DIY decking area for customers who want the look of traditional decking but without the hassle. If you have good DIY skills, you can use a jigsaw to cut the deck tiles to fit around an obstruction such as a downpipe, but we wouldn’t recommend cutting the tiles to create a circular area as this would impact the stability and performance of the product, reduce the point of interlocking and would not enable you to use the edge or corner ramps to complete your design.
