Most retaining wall failures are preventable. Plex Group explains the engineering principles that keep walls standing across Worcestershire, Cheltenham, and the Cotswolds.
See how we can help you!
The vast majority of retaining wall failures across Worcestershire come down to three engineering deficiencies: inadequate foundation depth, insufficient drainage, and poor backfill material. In clay-heavy ground around Evesham and Cheltenham, water builds up behind walls and creates hydrostatic pressure that pushes structures outward. Without drainage relief, even well-built walls eventually fail.
Every retaining wall needs a perforated land drain at its base, covered with free-draining angular aggregate rather than clay or soil. This drain carries water away before pressure builds. Weep holes through masonry walls provide additional relief. Plex Group installs drainage as standard on all retaining wall projects across Gloucestershire, Oxfordshire, and Warwickshire — it's not optional.
Foundation depth must match the retained height and soil type. Clay soils require deeper footings than granular ground. Backfilling with free-draining aggregate (not the excavated clay) maintains drainage performance. Plex Group follows BS 8002 earth-retaining structure standards across all retaining wall projects to ensure compliance and long-term safety.

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.
I can highly recommend Luke and his team. My garden had got a little overrun due to all the rain and needed some serious attention. They were on time and left my garden looking fantastic. I am so pleased that i will now be using them to maintain my garden permanently.
I had an overgrown garden and after placing an advertisement for someone to clear my garden they were the quickest to reply and offer their services. The work carried out was very good they were very efficient and I’m very pleased with the outcome.
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 were incredibly professional, polite and hard working. They did an amazing job cutting back my huge holly hedge and reducing four other large trees and bushes in the space of one day - it would have taken me weeks. Fast, efficient and very reasonably price.
Luke and his team are really lovely and professional. Cannot recommend him enough.
All the team are very personable, efficient, hard working, flexible and reliable they keep the customer in touch with any change of plans and timings. i can thoroughly recommend them.
Luke and the team are absolutely brilliant. A passion for what they do and personal but professional, so pleased to have found them!
We had some overgrown garden shrubs cut down to size. The service was professional and thorough from the initial visit, where Luke discussed various options regarding shaping and pruning, to the actual trimming.
Luke and his team offer a well run and professional service and are always willing to ensure the job is completed to customer satisfaction.
A relative's garden had become very overgrown. Luke and team come once a fortnight and have been slowly restoring it. It's already looking loads better. What's more, they take away all the garden waste and check in regularly to make sure they are meeting your requirements.
I can highly recommend Luke and his team, very professional from the quote to the finished job they went above and beyond replacing and installing a new fence for me. They did a fantastic job, will not hesitate to use them again. Great job guys. Thank you.
Our garden fence was damaged in a storm in December and a poor attempt to repair it by another company had left it sagging. The guys from Plex Procurement Group quickly worked out what needed to be done to fix and stabilise it and we are very pleased with the result.
Really pleased with the gardening the team are doing. They've helped get on top of the garden and are now maintaining it with regular visits. Very dependable and good quality work. Thanks Luke!
Patrick and his team came out to level our lawn out in harsh weather. Moving all the soil/mud by wheelbarrow to the front driveway. It was completed efficiently and at low cost. I would recommend Plex to my friends and family. We have them coming along to do some more work soon.
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 .
We're really pleased with the changes you've made to our front garden and would have no hesitation recommending you and your team. I really appreciate you coming to water the garden once the job was finished and the after sales service was superb.
Completely satisfied with work carried out and very impressed with work ethic of the whole team. Their level of commitment is exemplary. Our garden will now be much easier to manage with the raised borders. Have already booked for further work in the spring.
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!
The guys worked tirelessly for 10 days on my 100m hedge. This was a mammoth task, and they turned up on time every day with smiles on their faces. Polite, helpful, courteous and hard working. Price was also very reasonable. Would certainly recommend
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!
Luke & the team are extremely efficient and professional. Our lawns look very neat and tidy. Thank you.
I can easily rate Garden Guys as 5 star. The are good listeners, respectful and will always go that extra mile to make sure you’re left smiling. ? After a couple of really bad years have left me incapacitated to do the smallest of jobs, I have really needed their support.
Very obliging and efficient we have worked out a schedule that suits us both.
Hard working young team. Plenty of effective machinery and responded to special requests. Will be using them this summer and confident the relationship should develop.
Excellent service and great communication. Would highly recommend.
The boys were charming, came on a Sunday worked very hard all day, and did a fantastic job of literally halving the height of my very out-of-control hedge. Highly recommend.
They are really hard working efficient and tidy so the garden always looks better for the visit. They add more each time an have the sense to check stuff if they are less sure about odd plants or problems. Highly recommended.
Excellent job. Very nice lads. Our timings were out due to weather and for me going into hospital. They took the job on and completed it perfectly without me. Very trustworthy and no hesitation in recommending this business. Thank you, Jan
Extremely polite and did their best in the pouring rain!
Fantastic friendly team, hard working, have done many varieties of jobs for myself, and really great rates to boot!
