Choose paving by matching performance to the location before comparing colour and price. A shaded path, dining terrace and vehicle-bearing surface have different demands. The base, drainage and joints matter as much as the slab visible on top.

Define use and upkeep
Decide whether the surface is for dining, foot traffic, wheeled access or vehicles. Consider trees, shade and spills. A textured finish behaves differently beneath furniture and bare feet from a smooth showroom sample. Ask the supplier to confirm suitability for your use, rather than merely whether the product can be installed outdoors.
Compare porcelain, stone and concrete
Outdoor porcelain offers consistent dimensions but needs a suitable laying system. Natural stone varies, so inspect several samples to understand colour and texture. Concrete paving spans many finishes and budgets. Compare installation requirements, care and replacement options: no material is automatically best for every garden.
Understand product slip ratings
Marshalls currently lists R11 for Symphony Classic porcelain. The rating describes that product under a particular test. It does not guarantee all porcelain will be safe in every wet garden. Request information for your exact shortlist and intended location. Leaves, algae and poor drainage can still create slippery surfaces.
Examine samples outside
Compare materials with walls, boundaries and furniture in sun and shade. Wet samples to see colour changes. Consider marks and comfortable use. Check a laying plan: nominal dimensions may exclude joints, and narrow cuts around doors can undermine an otherwise attractive pattern. Larger slabs do not automatically produce the best result.
Give runoff an appropriate destination
Discuss falls, channels and drainage routes. Keep inspection covers accessible and coordinate levels with the house. Low-absorption slabs do not make a patio permeable. That depends on the whole installation, including joints, bedding, sub-base and ground. Water must not simply be directed towards a neighbouring property.
Price the complete installation
Compare preparation, cutting, laying materials, jointing, drainage and disposal. Ask whether sealing is required for the exact product and what it changes. Use compatible cleaners and keep spare units where practical. Cheap slabs can produce an expensive project when essential preparation is excluded from the advertised figure.
Check front-garden requirements
Government surfacing guidance identifies a threshold above 5 m² for certain impermeable domestic front-garden work without drainage provision to a permeable area. This is long-standing guidance checked in October 2026, not a general restriction on every back-garden patio. Confirm the requirements for your property before construction.
Agree edging and transitions before laying
Paving needs a considered finish where it meets soil, lawn, steps and adjoining surfaces. Ask how the edge will be supported and whether the detail allows easy mowing or planting maintenance. Check transitions at doors and paths, where awkward small height differences can be inconvenient. Cover frames should be included in the laying plan, not cut in casually afterwards. Discuss the jointing product too: its suitability depends on the slab, bedding system and expected use, and it has its own curing requirements.
Assess repairability and future matching
Ask how a damaged unit could be lifted and replaced, and whether the chosen range is readily available. Keep the exact product name, colour and batch information where supplied. Natural variation or later batch differences may make replacement units stand out, so retaining appropriate spares can be useful. Store them safely, following supplier guidance, rather than leaving unstable stacks in the garden. A paving choice should suit both the finished installation and the practical task of looking after it over time.
Summary
The right paving combines suitable performance with a sound base, drainage and achievable care. Discuss complete hard landscaping specifications with ALG Gardening And Landscaping Ltd before deciding which material belongs in your garden.
