My existing grass lawn always had standing water on the surface after rain. The water would stay in place in excess of a week even if it didn't rain again. As a result it was not possible to cut the grass and was totally unusable. Peter Mangnall gave me a quote to cure the drainage problem and lay Lazylawn Wonderyarn 26. Peter and two other members of his staff made a deeper dig and installed a drainage pipe to a cored hole in the brickwork, this was surrounded with Pea Gravel before topping it with MOT and grit sand followed with a membrane and the grass. His work has transformed my garden which is now a treat to go out in. On completion they cleaned up behind and left the rest of the garden and the access path as clean as it was when they started. The whole job was completed in one day. I will have no problem recommending the product and the installation team to anyone. Thank you Peter.
