This proved to be a challenging project due to the steepness of the slope, but our team of expert landscapers found a way! The area was constructed using a concrete haunch around the perimeter with a 100mm type 1 base and finished with sharp sand.
The second stage was the area at the bottom of the grass. One particular area was very soft and was thought to have a spring running beneath it, which would explain the water logging in the area. After digging a trial hole it was decided that the best way to solve the problem was to construct a solid edge all the way around, then fill the area with 200mm type 1 hardcore that was compacted to form a solid base. A geotextile membrane was then placed under a layer of plumb slate chipping.
