Porcelain vs sandstone vs concrete: patio materials compared
Porcelain is the low-maintenance favourite (non-porous, frost-proof, £££), natural sandstone the warm traditional choice (££, needs sealing), concrete flags the honest value (£, lasts decades on a proper base). All three outlast the house if the sub-base is right, and all three fail fast if it is not.

Porcelain: the current favourite
Vitrified porcelain paving is non-porous, which cascades into every advantage: nothing soaks in (no staining, no algae grip), frost cannot exploit absorbed water (genuinely frost-proof), and it needs no sealing, ever. It is dead flat, dimensionally consistent, and available in convincing stone and concrete effects. The honest downsides: it costs the most, cutting it needs specialist blades (and it chips in the wrong hands), it is slippery when icy, and the look is contemporary, on a Victorian terrace it can sit oddly. On Teesside's coast it is the default recommendation.
Natural sandstone: the traditional heart
Raj Green and Kandla Grey sandstone suit Teesside's brick stock beautifully, and no manufactured product matches real stone's warmth. It is porous, which means sealing every two to three years (skip it on the coast and algae and salt staining arrive), natural colour variation between batches (character to most, annoyance to some), and slightly uneven surfaces by nature. Mid-priced, mid-maintenance, and on period properties usually the right answer.
Concrete flags: honest value
Modern pressed concrete flags are not the council-grey slabs of memory: textured, coloured and profiled ranges mimic stone at half the price of porcelain. They are consistent, easy to lay well, easy to replace individually, and last decades on a proper base. The truthful limits: colours fade slowly over years, the premium end of concrete approaches sandstone pricing, and nobody's heart beats faster for them. For rental properties, utility areas and budget-led projects, they are the professional's quiet default.
The line that matters more than any of these
Every material above fails on a bad base and lasts on a good one. On Teesside clay: full excavation, compacted MOT Type 1, full mortar beds, engineered falls. Compare that line across quotes before comparing flag prices, it decides what your patio looks like in 2036 far more than the surface does.
