Retaining walls need more than materials — they need engineering. Plex Group explains what makes a retaining wall last in Worcestershire and across Gloucestershire, Oxfordshire, and Warwickshire.

The most common cause of retaining wall failure is water. Rainwater collects behind the wall, creating hydrostatic pressure that pushes the structure outward. In clay-heavy ground across Evesham, Cheltenham, and Moreton-in-Marsh, this problem is acute. Without proper drainage — perforated land drains, gravel backfill, and weep holes — even a solidly built wall will eventually move or crack.
Every Plex Group retaining wall begins with a detailed ground assessment. Footing depth ranges from 150mm for small garden terraces to 600mm+ for structural walls. Reinforced concrete footings distribute the wall's weight evenly, while the chosen system — concrete block, sleeper, stone, or gabion — is built in alignment with drainage and load requirements. Backfilling is done in compacted layers with angular stone closest to the wall.
Once built, retaining walls are integrated into the wider garden design. Steps, terraced planting, paved levels, and lighting can all be incorporated at the construction stage. Plex Group works across Gloucestershire, Oxfordshire, and Warwickshire to create structured, level garden spaces that are as functional as they are impressive.
