Cambridge Installers
A stable, permeable finish that starts with the base, assessed, prepared, and installed correctly.
What Goes Wrong
The finish is visible; the groundwork is not. That is where the difference between a lasting surface and an early failure is made.
Applying resin bound aggregate over a failing tarmac or concrete base causes the surface to crack and lift within months.
A site survey confirms whether the existing base will hold an overlay or needs excavating and replacing with MOT Type 1.
Falls set incorrectly at the sub-base stage leave standing water that undermines the surface and cannot be corrected afterwards.
Drainage direction is established during compaction, before the resin layer goes down, so water clears the surface properly.
Cambridge’s clay-heavy ground holds water beneath the surface, accelerating base movement if sub-base depth is underspecified.
The site assessment accounts for local ground conditions and sets the correct sub-base depth before excavation begins.
Resin bound aggregate laid without border edging spreads at the margins, leaving a ragged finish that deteriorates quickly.
Border edging is fixed in place before the resin layer is applied, containing the mix and giving a clean, defined finish line.
Scope of Work
Each stage is assessed and quoted separately, from ground conditions through to the finished trowelled surface.
Site survey of existing base, drainage falls, and ground conditions, followed by dig-out to the correct depth.
Compacted MOT Type 1 laid to the specified depth, with drainage falls set before the resin layer is applied.
Resin bound aggregate applied over a sound existing tarmac or concrete base where the survey confirms it will hold.
Edge restraints and drainage channels installed before the resin mix goes down to contain the surface and manage water.
UV-stable polyurethane resin and aggregate mixed on site, trowelled to an even layer, and left to cure for 24 hours.
Single or blended stone sizes chosen to suit the area.
SuDS-compliant finish for front drives and paths.
Guidance on planning requirements for listed or conservation properties.
Why Choose Us
The installation is only as dependable as the process behind it, here is how we make sure the right work gets done.
A local resin specialist visits to assess the base and drainage before figures are discussed.
Excavation, sub-base, drainage, and resin finish each appear as a separate line, not one combined number.
We connect you with independent local installers checked for the work, not a national call centre.
The survey determines whether an overlay will hold or a full dig-out is needed, you get the honest answer.
Installers familiar with local clay conditions specify the correct sub-base depth from the start.
How It Works
01
Tell us the area size, what is currently down, and how it drains so we can arrange the right specialist.
02
A local resin specialist visits to assess the base, drainage falls, and edging before quoting each stage separately.
03
Excavation, sub-base, and resin bound finish are completed in sequence, with the surface ready after a 24-hour cure.
