This project was for a client in Reading. We had to remove and replace wrongly laid Indian Sandstone Fossil Mint slabs in the patio (they had been laid the wrong way up). We also had to raise the patio level as it was too low against the level of the house.
Also, there was a problem with drainage on the lawn as it became waterlogged because the garden was at a lower level than the one next door so we had to put in some land drains. We removed the existing lawn and a level of soil. We then dug channels and put in perforated plastic pipe. We filled around pipe with shingle and put Terram on top to let water through but not let mud through. We the filled whole area with sieved topsoil and laid the turf for the new lawn.
