Loose stones on a resin driveway are ravelling, an installation failure rather than wear. Plex Group explains the causes and the repair across Worcestershire and Warwickshire.

Resin bound works because every stone is fully coated and bonded to its neighbours. That depends on a precise ratio of resin to aggregate, measured by weight and mixed in a forced action mixer for the full specified time. Stretch the resin to cover more area and the coating goes thin, the contact points between stones are starved, and the matrix has no real strength. The drive looks correct when it is finished because the stone is still sitting where it was trowelled, but it has nothing holding it, and it starts releasing within the first winter. Ravelling that appears across the whole surface rather than in one spot almost always points at ratio.
Resin cures through a chemical reaction, and that reaction is sensitive to both temperature and moisture. Laid below around five degrees the cure is slow and incomplete, and the surface can be driven on before it has reached strength. Moisture is worse. Damp aggregate, a damp base or rain within the curing window interferes with the reaction and leaves a brittle matrix that crumbles rather than flexes. Drives laid late in the season on a cold damp morning, or rushed ahead of forecast rain, are the ones we are called back to. Across Worcestershire and Warwickshire the sensible laying window is tighter than most homeowners are told.
These are two different systems and they are regularly confused, sometimes deliberately. Resin bound is stone and resin mixed together and laid as a permeable layer, typically 15mm to 18mm thick, with the stone held on all sides. Resin bonded is a resin layer spread onto a sealed base with dry stone broadcast over the top, which gives a rougher, non permeable finish where each stone is held at one point only. Bonded surfaces always shed some stone, because that is how the system works. If your drive is losing stone evenly from day one and water runs off rather than through it, you may have bonded rather than bound.
Ravelling also appears where the surface is being flexed. A resin layer is thin and relies on a rigid, stable base, so any movement below works the matrix and breaks it down from underneath. On clay ground around Evesham and Stratford-upon-Avon, a sub-base that was never deep enough deflects under vehicle weight in wet months, and the loss shows first in the wheel tracks and at the turning point where the loading is highest. Loose stone concentrated in those areas is pointing at the base rather than the mix.

We start with a full site assessment to establish whether the loss is localised or across the whole drive, because the two have different answers. We check the depth of the resin layer, look at how cleanly the stone has released, and test the surrounding areas for soundness, since ravelling almost always spreads beyond the bare patch. Localised failure is cut out in a clean square back to sound material and relaid with a matched aggregate and a correctly measured resin batch, keyed into the existing edge. Where the ratio was wrong across the whole drive, patching is a waste of money and we relay the surface, which on a sound base means a fresh wearing course rather than a full rebuild. We mix in controlled batches with a forced action mixer, work to the manufacturer's resin to aggregate ratio by weight, and lay only when the base is dry and the temperature is within the specified range.

Stone coming out of a resin surface is an installation fault rather than ordinary wear, and it can be put right once the extent is properly established. Plex Group repairs and relays resin driveways across Worcestershire, Gloucestershire, and the Cotswolds. Get in touch to arrange an assessment.

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.
