Following the development of a new house to the rear of our clients it has resulted in the gardens to 2 properties being flooded every winter meaning the gardens were inaccessible. It was for this reason a drainage engineer had designed a french drainage system with herringbone runs to collect the ground water in the gardens and discharge into the combined sewer. Our client had instructed us to install 160m of french drainage to 2 properties then coming through the garage and constructing a manhole within the driveway over the existing sewer to make connection of the new drain. Due to access restrictions into the garden we were only able to use a micro excavator and lots of trips with the wheel barrows with soil and shingle!
