The first step is surveying the route, measuring width, checking the fall direction, and identifying any drainage issues along the line. Cambridgeshire clay can shift and cause paths to sink unevenly, so sub-base depth is set to suit the ground conditions on that specific route rather than a fixed standard.
Excavation removes the existing surface or topsoil to the required depth. A compacted sub-base goes down first, followed by the bedding layer and then the surface material. Edging is set before the field is laid to hold the perimeter and prevent the surface from spreading at the sides over time.
Surface options include paving slabs for a formal route, block paving for side access, and natural stone for back garden walkways. Pointing or jointing compound is applied once the bedding has cured. The quote covers excavation, sub-base, surface material, edging, and pointing as separate lines so the full cost is clear before work starts.
