Installation starts with a full dig-out to the correct depth for the ground conditions. On Peterborough’s clay-heavy soil, a compacted aggregate base layer is essential before any screed bed is laid. The depth of that base is not a fixed number, it is determined by what the survey finds beneath the turf.
Porcelain slabs are laid on a screed bed with joint spacers to maintain consistent gaps. Grout is applied only after the bed has cured. Wet East Midlands winters make anti-slip finish ratings a practical consideration, so the installer confirms the surface grade before ordering slabs.
Drainage fall is set during the screed stage, not corrected afterwards. The finished surface must slope away from the house at a gradient that clears standing water without creating a noticeable tilt. New build gardens across Peterborough typically need the full sequence, dig-out, base, screed, slab, joint, from bare ground up.
Why Choose Us
Why request a porcelain patio survey in Peterborough?
Porcelain demands precise groundwork. Here is what every survey covers before installation.
Itemised Quotes, No Surprises
Dig, sub-base, screed and paving are quoted as separate line items so you see exactly what each stage costs.
Ground Survey Before Any Work
A site visit assesses soil conditions and existing base before a single slab is ordered or a price is fixed.
Local Knowledge of Clay Ground
Installers familiar with Peterborough’s clay soil specify the correct base depth rather than applying a standard figure.
Anti-Slip Grade Confirmed Upfront
Surface finish rating is agreed before slabs are ordered, matched to the patio’s aspect and wet-weather exposure.
Drainage Checked at Every Stage
Falls are verified at screed stage and again once slabs are down, before grouting seals the surface.
Yes, porcelain is one of the most practical outdoor paving materials available. It is frost-resistant, virtually non-porous, and does not stain or fade the way softer stones can. It handles heavy foot traffic and outdoor furniture without marking, and the surface stays consistent in colour year after year.
Will a porcelain patio be slippery when wet?
Outdoor porcelain slabs are manufactured with a textured surface specifically to reduce slip risk when wet. The key is choosing a slab with an R11 slip rating or higher, which is the standard recommended for external use. A smooth or polished finish is not suitable outdoors and should be avoided.
Can porcelain slabs go over my old patio?
Laying over an existing surface is only viable if the old base is structurally sound, level, and has no drainage problems. In most cases, the existing patio is lifted so the sub-base can be inspected and corrected. Laying over a failing base transfers those problems to the new surface and shortens its lifespan.
What is involved in laying porcelain patio slabs?
The process covers excavation, compacting a hardcore sub-base, laying a sharp sand or mortar bed, cutting slabs to fit the layout, and pointing the joints. Porcelain requires a full-bed mortar fix rather than spot bedding, because its low porosity means it will not bond reliably on a partial bed.
What is included in the job, such as digging out, the base and edging?
A full installation typically includes excavation to the required depth, disposal of spoil, a compacted hardcore sub-base, a mortar bed, the porcelain slabs themselves, and jointing. Edging restraints, steps, or drainage channels are usually quoted as separate line items so you can see exactly what each element costs.
What does a porcelain patio cost?
Guide prices run from £1,500-£2,000 (Small porcelain patio installation) to £3,200-£5,000 (Larger porcelain patio installation). The slab itself is a significant part of the material cost, so the range you choose has a direct effect on the overall figure.
Will there be any hidden costs once the work starts?
A detailed written quote should cover all foreseeable work. The one area where additional costs can arise is ground conditions: if the excavation reveals unstable or waterlogged sub-soil that needs extra hardcore or drainage, that is flagged before proceeding rather than added to the final invoice without notice.
How do I know the finished patio will sit level and drain properly?
Porcelain patios are laid with a fall of around 1 in 80 away from the house, which is enough to shed water without being noticeable underfoot. The sub-base is compacted and checked for level before any slabs go down. Where drainage is a known issue, a channel drain can be incorporated into the design. See Patio Drainage & Levelling for more detail.
