Love this product the end result looks so very profesional. We decided to avoid wood decking on our patio seating area and go for more durable gravel and corten core edging as materials. We were a bit hesitant at the beginning as we didn’t know this product but it’s so so sturdy. We covered 3 different types of ground: ballast, slabs and lawn areas that’s why the membrane addition was so important for us. All questions were answered over the live chat and later over the phone. Delivery happened 2 days before originally estimated which helped us to work on a bank holiday weekend. They are super light and easy to place and replace as we needed. Over the moon with nidagravel and finished result it’s keeping gravel in place on the seating area despite table and chairs moving constantly and the traffic for a busy family patio. we love our patio.
