Porcelain Paving
A non-porous, frost-resistant surface that stays clean without sealing or annual maintenance.
Getting It Right
The material is unforgiving of shortcuts, these are the failure modes that matter.
Porcelain laid onto a sand bed will not bond; slabs lift within a single winter as moisture gets beneath them.
Each slab is back-primed with a slurry primer and set onto a full mortar bed, creating a permanent mechanical bond.
Cambridgeshire clay shrinks and swells seasonally; an under-depth sub-base lets the whole surface move and crack.
The installer sets sub-base depth to account for local clay conditions and compacts it before any bedding begins.
Cutting porcelain with an angle grinder leaves micro-fractures at the edge that widen over time and ruin tight joints.
A wet saw with a diamond blade produces clean, square cuts that hold a consistent joint width across the whole patio.
Pointing with standard mortar leaves no room for thermal movement; joints crack and open up after the first cold spell.
A flexible jointing compound accommodates minor thermal movement and keeps the joints sealed without cracking at the seams.
Scope of Work
From ground preparation through to finished jointing, each stage is quoted as a separate line.
Excavation, Type 1 compaction and depth set to Cambridgeshire clay conditions before bedding starts.
Back-priming each slab and laying onto a full mortar bed for a permanent, lift-resistant bond.
Wet saw cutting for clean edges, accurate falls away from the house and tight, consistent joints.
Jointing compound applied across the finished surface to seal gaps and allow thermal movement.
R-rating confirmed before slabs are ordered.
Falls set away from the house and DPC.
Textured, brushed or smooth face options.
Neat perimeter cuts and border courses.
Why Choose Us
Porcelain is an unforgiving material, the installer’s process and accountability matter as much as the slab itself.
A site visit assesses ground conditions and drainage before quoting.
Excavation, sub-base and bedding are quoted as separate lines, not buried in a day rate.
Porcelain, sandstone and limestone are compared during the survey so you choose with full information.
The R-rating of every slab is checked before ordering, not assumed from a brochure description.
Sub-base depth is set to local Cambridgeshire clay conditions, not a generic specification.

Common Questions
Porcelain slabs cost more because the material itself is denser and harder to manufacture than concrete or sandstone, and the installation requires a more rigid, precisely prepared base. Cutting the slabs also demands diamond-tipped tools. Those material and labour costs combine to push the overall price higher than most alternatives.
Most porcelain patio installations come in at £1,800-£3,200, varying with the area size, slab format and thickness chosen, how much existing material needs removing, and how much groundwork the sub-base requires. Intricate cuts around curves or steps add time and therefore cost.
Porcelain is worth the extra cost if you want a surface that resists staining, frost and fading with minimal upkeep over many years. If budget is the primary concern, Indian sandstone or block paving deliver a good result at lower cost. The right answer depends on how you weigh upfront spend against long-term maintenance. Compare your options
Yes. Porcelain has a near-zero absorption rate, so moss, algae and stains struggle to take hold. An occasional rinse with a hose or pressure washer is usually enough to keep it clean. Unlike natural stone, it does not need sealing.
It depends on the surface finish. Polished porcelain can be slippery when wet and is better suited indoors. For an outdoor patio, choose slabs with a textured or matt finish rated R11 or above for slip resistance. Always check the slip-rating specification before ordering.
Porcelain suits most garden uses, dining areas, entertaining spaces and pathways, provided the sub-base is built correctly and the slab thickness matches the load. Thicker 20 mm slabs handle foot traffic and light furniture well. If you plan to drive or park on the surface, a different material is more appropriate.
The main drawbacks are higher material cost, the need for precise groundwork, and the difficulty of cutting slabs on site without specialist tools. If a slab chips or cracks, matching the original batch later can be tricky. It is also unforgiving of a poorly prepared sub-base, which can cause cracking or movement.
Yes, more so than concrete flags or sandstone. Porcelain requires a fully bound mortar bed rather than a dry-lay method, and cutting demands diamond-blade wet saws. The sub-base tolerances are tighter too. An installer without experience of the material is more likely to produce a finish that fails early.
