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.

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.

From the initial meeting to the final clear up Patrick and Luke were unfailingly polite and professional. Patrick’s quotation for the work was sensible with a detailed breakdown. The work was started on time and was kept to time. The resulting terracing exceeded expectations and the work area was left cleaner than when the team arrived. I cannot thank Patrick, Luke and Jake enough for all their work and would have no hesitation in recommending PLEX Group.
It has been a pleasure having Plex work with me on my garden project. Totally engaged, very communicative and prompt. Access to my property is difficult but they just worked around any problems with a refreshing 'can do' attitude. I would happily recommend Plex to anyone working on a garden project.
Fantastic work and would highly recommend. The team were professional, friendly, considerate, hard working and flexible to ensure the works met our needs and expectations. Really nice team to have on site and were respectful and kept it as tidy as they could. Very impressed with the work and looking to get them to come back to do a couple of other jobs for us in the future.
I am really happy with the work that Plex did. They came up with solutions to problems that arose quickly, efficiently and without any stress. They were friendly, professional, organised, efficient and had excellent communication.
We have recently had a new garage installed from the Plex team and we are thrilled with the finished product. Can't thank Patrick Luke and their team enough. Would highly recommend.
I would highly recommend Luke and Patrick and their team. They are all extremely polite and hard-working. They put up a new pergola in our back garden and tidied up the edges of the garden. An excellent job.
Patrick, Luke and their team have transformed our sloped garden giving us a lovley functional space. They removed a hedge sadly over run with brambles with a fence gaining us a couple more meters of garden too! Despite having a week of rain they did their best to clear up at the end of the job. We would highly recommend this professional team.
Luke and Patrick have completed two projects for us now. They are the most polite and professional people with a hardworking team of individuals. Nothing is too much trouble for them.
Luke and his team are really lovely and professional. Cannot recommend him enough.
Luke and the team are absolutely brilliant. A passion for what they do and personal but professional, so pleased to have found them!
Really pleased with the concrete base for my carport that was completed by the team , worked really hard in poor weather conditions . Great job would definitely recommend the team .
Our garden has never looked better - hard-working, thorough, and also great at getting in touch if there's a change to the schedule, etc. They have nursed our box hedging back to health. Before and and after photos are a bonus!
Competitive price wise even though the work carried out was to a very high standard. I was very pleased with the end result and impressed with the tidiness they left the garden after all the work was carried out. A very happy customer!
Very obliging and efficient we have worked out a schedule that suits us both.
