Can You Lay a Resin Driveway Over an Existing One in Lincoln?

One of the first questions we get asked in Lincoln is whether a resin driveway can go straight over the old one, or whether the whole lot has to come up first. It is a fair thing to ask, because the answer changes the price by a good few hundred pounds and the job by a day or two. The short version is: sometimes yes, sometimes no. A sound, level tarmac or concrete drive can often take a resin surface laid directly on top, which skips the digging, the muck-away and a chunk of the cost. A cracked, sunken or crumbling one cannot, and pretending otherwise just buys you a driveway that fails early. This guide walks through when an overlay works, when it does not, and the drainage catch that trips people up on Lincoln’s older, low-lying plots.

What Laying Over an Existing Drive Actually Means

An overlay means the resin bound surface is laid directly onto your current tarmac or concrete, using it as the base rather than digging down and building a new one. The existing surface has to be cleaned, dried and sometimes primed first, then the resin and stone go on top at a set depth, usually around 15 to 18mm for a driveway.

Done on the right base, it is a genuinely good option. You keep the solid, compacted foundation that is already there, and you avoid the messiest, most expensive part of the job. The catch is that the resin is only ever as good as what it sits on. If the base moves, cracks or holds water, the surface on top will follow it - so the whole decision hinges on the state of what you already have.

When a Resin Overlay Works in Lincoln

An overlay is usually on the cards when the existing drive ticks a few boxes. It needs to be structurally sound, reasonably level, and free of significant cracks or sinking. It also needs to drain - either through the base itself or with drainage added at the edges. A tarmac or concrete drive that was laid properly ten or fifteen years ago and has simply gone tired and grey is often a perfect candidate.

Plenty of Lincoln homes fit that description. A lot of the postwar semis out towards Ermine and Birchwood have solid concrete drives that are structurally fine but dated, and those take a resin overlay well. If yours is stable underfoot and water does not pool on it after rain, there is a good chance it can stay. A proper resin bound driveway laid over a sound base performs just as well as one built from scratch.

When the Old Drive Has to Come Up

Some surfaces cannot be saved, and laying resin over them is a false economy. If the concrete is cracked and lifting, if the tarmac is crumbling or full of potholes, or if the drive has visibly sunk in places, the problems underneath will telegraph straight through a new surface within a year or two. Block paving is another one to watch - individual blocks flex and shift, so resin laid over the top rarely stays flat for long.

In those cases the honest advice is to dig it out and build a fresh, permeable sub-base. It costs more up front, but it is the difference between a driveway that lasts two decades and one you are unhappy with by the following winter. We would always rather turn down an overlay than lay one we know will fail.

The Drainage Catch on Low-Lying Plots

Here is the part homeowners rarely think about. Resin bound is permeable - water passes straight through it. But if you lay it over solid concrete or tarmac, the water goes through the resin and then hits an impermeable layer it cannot soak into. On a free-draining plot that is fine, but on the flatter, clay-influenced ground down in the Witham valley, that trapped water has to go somewhere.

The fix is to plan the drainage before laying, usually a channel drain along the threshold or a permeable edge so the water has an exit. It also matters for planning: a resin surface counts as permitted development because it is permeable, but overlaying an impermeable base can change that picture if the run-off ends up on the road. The government’s guidance on permeable surfacing of front gardens and the Planning Portal’s page on paving a front garden are both worth a read if you are overlaying rather than starting fresh.

What You Save by Overlaying

When an overlay is possible, the savings are real. You skip the excavation, the removal and disposal of the old surface, and the materials and labour for a new sub-base. That can take a meaningful slice off the total and shave a day or more off the job, which matters if the drive is your only parking.

It is worth keeping the saving in perspective, though. The point of an overlay is to reuse a base that is genuinely up to the task, not to cut a corner on one that is not. A slightly cheaper job that fails early is the most expensive driveway of all. If you want to see how the numbers break down either way, our 2026 guide to resin driveway costs in Lincoln goes through what drives the price up and down.

How We Check Before Committing

None of this can be judged over the phone. On a free site visit we look at the existing surface, check it for movement and cracking, see how it drains after rain, and work out whether it can stay or needs lifting. Only then can anyone give you a straight answer and an honest price.

If an overlay is the right call, we will tell you. If it is not, we will tell you that too, and explain why. When you are comparing quotes, be wary of anyone who promises an overlay without properly looking at the base first - and it is always worth checking your installer against a vetted scheme like TrustMark.

Frequently Asked Questions

Can you lay a resin driveway over existing tarmac in Lincoln?

Often, yes. If the tarmac is solid, level and well-drained, resin bound can be laid straight over it, which saves on excavation and cost. If the tarmac is cracked, crumbling or potholed, it needs lifting first, as the damage would show through the new surface.

Can you put resin over a concrete driveway?

Usually, provided the concrete is sound and does not crack, lift or sink. Sound concrete makes a very good base for a resin overlay. Because concrete is not permeable, drainage needs planning at the edges so water passing through the resin has somewhere to go.

Can resin be laid over block paving?

It is rarely a good idea. Individual blocks can shift and flex, and that movement tends to work through a resin surface laid on top, leaving it uneven. In most cases block paving is better lifted and replaced with a proper permeable sub-base.

Does overlaying a driveway need planning permission in Lincoln?

A permeable resin surface itself is permitted development. But laying it over an impermeable base such as concrete can affect drainage, and if run-off ends up on the road for a surface over five square metres, permission may be needed. Check with City of Lincoln Council if you are unsure.
