Ever wondered what really goes into preparing a professional patio or garden path? In this post, we take you behind the scenes at Plex to show the full process — from excavation to sub-base compaction — that ensures every surface stays level, strong, and long-lasting. Learn the science, precision, and materials that make the difference between a short-lived patio and one that lasts decades.

Every Plex Group project starts by stripping turf, topsoil, and organic matter to a depth of 150–200mm. We check for underground services, remove roots and debris, then set precise drainage falls using laser levels — a minimum 1:60 gradient directing water away from buildings. In clay-heavy areas like Evesham, Cheltenham, and Moreton-in-Marsh, getting this right is non-negotiable.
MOT Type 1 crushed aggregate is laid in 50mm layers and compacted with a vibrating plate until firm. A geotextile membrane may be placed beneath to prevent weed growth and sub-base migration into clay soil. In areas prone to heavy rainfall across Gloucestershire and Warwickshire, linear drainage channels or soakaways are installed at this stage.
A sharp sand bedding layer of 30–50mm is screeded to millimetre accuracy before slabs are laid. Porcelain and natural stone are set on a semi-dry mortar bed; block paving uses flexible jointing. Polymeric grout seals the joints for weed resistance and long-term durability — the final step before handover.

Ivy roots into the core of a drystone wall and forces the stones apart, and pulling it off makes the damage worse. Plex Group explains what is happening and the right way to fix it across the Cotswolds.

A bulging drystone wall means the core has failed and the faces are separating. Plex Group explains why it happens and how a proper rebuild works across the Cotswolds and Gloucestershire.

Potholes in a gravel driveway mean the gravel is sitting on soil with no proper sub-base or membrane beneath it. Plex Group explains the causes and the permanent fix across Worcestershire and the Cotswolds.
