Stone Patios
A stone patio that stays level, drains cleanly, and holds its joints for years, not one that rocks and pools after the first winter.
What Goes Wrong
The stone itself rarely fails first, the base, the drainage, and the jointing do.
A mortar bed laid too thin or too dry over Cambridgeshire clay will crack when the ground shifts through winter.
A plate-compacted Type 1 sub-base at the correct depth stops the bedding layer moving with the clay beneath.
Slabs laid flat collect water in low spots, accelerating joint washout and leaving standing water after rain.
Falls are set away from the house before the first slab goes down, so water clears the surface by design.
Standard sand joints wash out quickly under limestone or granite, leaving gaps that let slabs rock and weeds establish.
Jointing sand or mortar is chosen to suit the slab density and porosity, then worked in after the bedding has cured.
Without edge restraints, the sub-base spreads outward over time and the perimeter slabs drop or tilt.
Edge restraints are fixed before the field slabs are laid, holding the base in place across the full patio area.
Stone Types & Scope
Each stone has different density and porosity, so bedding depth and jointing are specified per material, not applied as a single standard.
Limestone slabs on a screeded bedding layer with jointing mortar suited to the stone’s porosity and surface finish.
Sandstone on a compacted sub-base with falls set to drain away from the house and slip-resistant finish available.
Dense granite slabs bedded on a full mortar layer with edge restraints and stone-matched jointing compound.
Existing stone lifted, base assessed, and slabs relaid where the sub-base is sound or rebuilt where it has failed.
Plate-compacted Type 1 at the depth the ground needs.
Level bed checked before each slab is placed.
Falls graded away from the house at the outset.
Perimeter fixed first to hold the base in place.
Available on limestone and sandstone for wet use.
Stone & Stability
Base failure and standing water are the two most common reasons a natural stone patio needs lifting within a few years.
Limestone, sandstone, and granite each have different densities and absorption rates, which affects the bedding layer and jointing material used. A site check confirms ground conditions, existing drainage routes, and the fall direction needed before any material is ordered or laid.
Cambridgeshire clay can shift enough over a winter to crack a mortar bed that was too thin or too dry. Sub-base compaction is carried out with a plate compactor, and the screeded bedding layer is checked for level before each slab is placed. Edge restraints are set first to hold the perimeter and prevent the base from spreading.
Jointing sand or mortar is worked into the joints once the bedding has cured, and a slip-resistant finish is available on limestone and sandstone where the surface will be used in wet conditions. The quote lists sub-base, bedding, slabs, edging, and jointing separately so there are no hidden groundwork costs.
Why Choose Us
We schedule a survey that checks Cambridgeshire ground conditions. Every element of the job is quoted as a separate line.
Installers familiar with Cambridgeshire clay assess sub-base depth before quoting.
A site visit confirms drainage direction and ground conditions before any material is chosen.
Dig, sub-base, bedding, slabs, and jointing appear as separate lines, no bundled groundwork costs.
The installer advises on limestone, sandstone, or granite to suit the garden’s use and exposure.
We schedule surveys across Huntingdon, Godmanchester, St Ives, and Brampton.
How It Works
01
Tell us the size, what is down there now, and how the ground drains after rain.
02
An on-site visit checks ground conditions. Each element is quoted as a separate line.
03
Sub-base, bedding, slabs, and jointing are completed in sequence, then the finished patio is handed over.
