Cambridge residential frontages range from Victorian terraces with narrow approaches to modern new build plots with open frontages, and the base conditions vary just as widely. A site survey covers ground condition, drainage falls, and existing base suitability before any design choices are finalised. That sequence matters: selecting an aggregate and layout before knowing whether the base needs work leads to a quote that changes later.
Aggregate blends are available in a range of stone types, sizes, and colour tones. The specialist brings samples to the site survey so choices are made in the actual light conditions of the property rather than from a catalogue. Edging options, aluminium, steel, or stone kerb, are selected at the same stage. Drainage gradient is set during sub-base preparation, typically at a minimum fall of 1:80 across the surface.
Cambridge’s clay-heavy ground makes a drainage check a standard part of every site assessment, not an optional extra. Where the existing base is sound, an overlay may be possible. Where it has moved or failed, excavation and a new MOT Type 1 sub-base are specified before the resin bound layer goes down. The design is confirmed once the base route is clear, so the final quote covers the full scope without revision.
