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.
