An overlay is only viable when the existing surface meets specific conditions. It must be structurally sound, no hollow sections, no active cracking, and no soft spots beneath. It must be level within acceptable tolerances, as resin applied over an uneven base will show every undulation in the finished surface. And it must be dry: moisture trapped beneath the resin binder causes adhesion failure, which is why a moisture reading is taken before any primer is applied.
Where the surface passes inspection, it is cleaned, any minor cracks are filled and primed, and an overlay bonding primer is applied to ensure the resin binder keys correctly. The resin and aggregate are then mixed and hand-trowelled across the prepared surface. Chigwell properties with older concrete or tarmac paths and patios are often good candidates for this approach, avoiding the cost and disruption of full groundworks.
Essex Building Regulations drainage requirements for permeable external surfaces apply to overlay work just as they do to new installations. Where a front garden surface is being changed, the specialist confirms whether the permeable resin bound finish satisfies those requirements or whether a highways or planning check is needed first. That assessment happens at survey stage, before any work is agreed.
Why Choose Us
Why choose us for resin overlay work in Chigwell
Base assessment and compliance checks are built into every survey, not added on as an afterthought.
Itemised Quotes, Not a Single Price
Preparation, priming, and overlay application are quoted as separate line items so you see exactly what each stage costs.
Survey Before Any Commitment
No work is agreed until the base has been assessed for moisture, levelness, and structural soundness in person.
Drainage Compliance Checked at Survey
Essex drainage requirements and any highways or planning considerations are confirmed before the overlay is specified.
Direct Scheduling, Not a Call Centre
We schedule overlay site visits on Chigwell residential properties regularly.
Honest Scope, Not an Oversell
If the base is not suitable for an overlay, the survey will say so clearly rather than proceed with work that will fail.
Questions about resin overlay on existing surfaces
Can resin be laid over old concrete or tarmac?
Yes, if the surface is structurally sound, reasonably level, and free from active cracks or trapped moisture. If hollow sections, soft spots, or damp are found during the survey, those areas need repair before an overlay can be specified.
What happens if the base is not suitable for an overlay?
If the base fails the soundness, moisture, or level check, the overlay cannot go ahead as planned. Proceeding on a failing base means the new finish will crack, delaminate, or show movement within months, the survey exists to catch this before any money is spent.
What does the inspection actually check?
The specialist checks for hollow or soft sections, active surface cracks, moisture levels beneath the surface, and whether the base is level within overlay tolerances. All three must pass before primer or resin binder is specified.
Do I need planning permission for a resin overlay on my front garden?
It depends on whether the work changes drainage or the layout of the frontage. A resin bound finish is permeable, which often satisfies Essex Building Regulations drainage requirements, but a highways or planning check may still be needed. The survey confirms this before work is agreed.
How long does a resin overlay take to cure?
Cure time varies with temperature and humidity, but most resin bound overlays are walkable within 24 hours and fully cured within 72 hours. The expected cure window gets confirmed based on conditions on the day.
Is an overlay suitable for a surface with lots of cracks?
Minor surface cracks can be filled and primed before the overlay is applied. Widespread or active cracking, where the base is moving, usually means the surface is not stable enough to carry an overlay without the cracks reflecting through the new finish.
Describe the area and what is currently down. We’ll schedule a site visit to assess the base, confirm drainage compliance, and return an itemised quote covering every stage separately.
