Tarmac vs resin vs block paving: which driveway is right for your Dublin home?

Tarmac, resin bound and block paving are the three driveway surfaces Delaney Tarmac is asked about most often in Dublin. Each one does a different job. None of them is universally best. The right choice depends on the house, the budget, the ground conditions, the council requirements and the maintenance the homeowner is willing to take on.

This article runs through the three honestly, side by side, with the trade-offs spelled out. It is not a sales pitch for any one of them. Delaney installs all three, and recommends whichever one actually fits the property.

Tarmacadam: the workhorse

Tarmacadam, also known as tarmac or asphalt, is the most common driveway surface in Ireland and accounts for roughly 60 percent of new driveways across Dublin. It is the cheapest of the three on a per-m² basis, the fastest to install and the most versatile across property types.

• Cost: €50 to €95 per m², all-in.
• Lifespan: 15 to 25 years properly laid on a correct sub-base.
• Maintenance: very low. Occasional pressure wash. No sealing.
• Permeability: none. Drainage falls required.
• Best for: large driveways, longer rural approaches, period properties wanting a clean plain finish, budget-conscious homeowners.
• Watch-out: needs a proper edge restraint (concrete haunching or granite setts) and a 150 to 200mm hardcore sub-base. Without those, it cracks and sinks in 3 to 5 years.

In Dublin specifically, tarmac suits commuter-belt estates in Tallaght, Lucan, Swords and Clondalkin where the existing driveways are 1990s and 2000s developer-finish concrete that needs replacing. It also suits long country approaches in Saggart, Castleknock and the rural-edge corridor where the cost-per-m² matters more than the visual finish.

Resin bound: the contemporary upgrade

Resin bound is the fastest-growing driveway surface in Dublin and has overtaken block paving as the premium choice for contemporary frontages. It mixes UV-stable polyurethane resin with a chosen Daltex aggregate, hand-trowelled onto a prepared base to give a smooth, fully permeable finish.

• Cost: €150 to €250 per m², all-in. Premium of the three.
• Lifespan: 20 to 25 years with minimal maintenance.
• Maintenance: very low. Occasional pressure wash. No sealing, no weeds.
• Permeability: fully permeable, SuDS-compliant out of the box.
• Best for: contemporary homes, period properties wanting a modern lift, planning-compliance situations, tight Dublin sites where SuDS rules apply.
• Watch-out: needs a sound base. Existing tarmac can often be overlaid, saving on excavation. A failed concrete base needs full removal first.

In Dublin, resin suits south Dublin postcodes like Foxrock, Blackrock, Dalkey and Sandycove where homeowners want a clean modern frontage, and newer developments in Adamstown, Cherrywood and Clongriffin where the modern house architecture demands a matching surface. It also wins on tight sites in Ranelagh, Ballsbridge and Rathmines where the existing driveway is too small to justify a tarmac job and the homeowner wants a more characterful finish.

Block paving: the traditional kerb appeal

Block paving has been the kerb appeal default for Irish driveways since the 1990s. The patterns, colour options and individual blocks give it a decorative quality neither tarmac nor resin offers. It is the most repairable of the three: if a section settles or a block cracks, it can be lifted and relaid without redoing the entire driveway.

• Cost: typically quoted per project after a site visit, depending on block range, pattern complexity and feature borders.
• Lifespan: 25+ years properly laid on a proper sub-base.
• Maintenance: moderate. Occasional re-sanding of joints. Weed control if jointing sand washes out.
• Permeability: standard block paving is not permeable. Permeable block paving (with wider joints and a special sub-base) is available at additional cost and meets SuDS requirements.
• Best for: period homes wanting a traditional decorative finish, properties where individual sections may need lifting in future, homeowners who want pattern and colour choice.
• Watch-out: coastal Dublin (within 1km of the sea, so Sandymount, Clontarf, Howth, Malahide, Portmarnock) can see efflorescence (white salt deposits) on standard block paving from salt-air exposure. Resin or salt-air-tolerant tarmac are better in these locations.

In Dublin, block paving suits period Victorian and Edwardian terraces in Blackrock, Ranelagh, Drumcondra and Phibsborough where the traditional decorative finish ties to the house style. It also works on detached family homes in Castleknock, Malahide and Foxrock where the homeowner wants colour and pattern variation rather than a single uniform surface.

Side by side

Across the four factors that matter most to Dublin homeowners, the three surfaces shake out roughly as follows.

• Lifespan: block paving longest (25+ years), resin and tarmac close behind (20-25 and 15-25 years).
• Maintenance: resin and tarmac both very low. Block paving moderate (re-sanding joints every few years).
• Permeability: resin fully permeable out of the box. Block paving permeable as an upgrade. Tarmac not permeable.
• Cost per m²: tarmac lowest, block paving middle, resin highest.
• Repairability: block paving lifts and relays section by section. Tarmac patches but rarely matches colour. Resin lifts and relays only with specialist work.
• Visual finish: tarmac plain, resin contemporary, block paving decorative and traditional.

How to decide

A few practical questions to ask yourself before requesting a quote.

1. What style is your house? Period properties tend to look right with block paving or plain tarmac with a granite sett border. Contemporary or modernised homes tend to look right with resin.
2. How big is your driveway? Larger areas (60m²+) push tarmac into the most cost-effective bracket. Smaller areas (under 40m²) make resin and block paving the better value because the per-m² difference matters less on a small absolute footprint.
3. Does your front garden require SuDS compliance? If you are paving over more than 5 square metres of unpaved ground in Dublin, the answer is probably yes. Resin handles this out of the box. Permeable block paving handles it at additional cost. Standard tarmac does not.
4. Are you near the coast? Within 1km of the sea, salt-air efflorescence on standard block paving is a real risk. Resin or salt-air-tolerant tarmac is the safer call.
5. What maintenance are you willing to do? Resin and tarmac are essentially fit-and-forget. Block paving needs occasional joint re-sanding to look its best.

A good driveway contractor will ask you the same questions on the site visit before recommending a surface. If a quote comes back recommending one surface for every property regardless of context, the contractor is selling what they have, not what suits you.
