Had an area of 70 square meters where we wanted to put gravel down. After some research we settled on the Nidagravel (130) product. It was easy to lay and has given us a brilliant solid and stable finish to our drive. Would definitely recommend this product 100% and in particular the large sheet size available from Nidagravel. The only small negative was that the product arrived 24 hrs later than suggested on the website (although courier was excellent when it did arrive) and Nidagravel could be better at responding to emails and phone messages! Otherwise it would have been a 5 star review.
