Block Paving or Resin: Which Driveway Is Right for You?

Block paving is a flexible system. Blocks sit on a screeded sand laying course over a compacted sub-base, confined by concrete-haunched edge restraints, with kiln-dried sand brushed into the joints. Load spreads sideways through the interlocking blocks.

Resin bound is a rigid system. It requires a solid base — porous asphalt or permeable concrete over the sub-base — with the resin and aggregate mixed on site and trowelled out at 15 to 18mm.

Both share the same excavation and sub-base, so a large part of the cost is identical. Block paving takes longer to lay because each unit is placed by hand; resin goes down quickly once the base is ready but the base itself takes an extra day.

Resin's rigidity means it can be laid over an existing sound tarmac or concrete drive, which frequently makes it the cheaper option on a resurfacing job. Block paving always needs the full build-up.

This is the biggest practical difference. Block paving needs its jointing sand topped up periodically, weeds pulled from the joints, and an occasional clean. It is not onerous, but it is an ongoing task, and drives that are neglected show it quickly.

Resin needs sweeping and an occasional wash. There are no joints, so there is nowhere for sand to escape from or weeds to germinate. Nothing needs re-sanding, sealing or repointing.

Weeds are the most common complaint about block paving. They do not usually grow up from below — they germinate in organic debris collecting in the joints — but the joints are what makes them possible. Resin's continuous surface eliminates the issue almost entirely.

Moss favours block paving for the same reason. On a shaded north-facing frontage, which many Essex terraced and semi-detached homes have, resin stays visibly cleaner with less effort.

Block paving's outstanding advantage is repairability. If a section sinks, if a service trench crosses the drive, or if a corner is damaged, the blocks are lifted, the base corrected and the same blocks relaid. The repair is invisible and costs mostly labour.

It also means the drive can be altered. Widening it, adding a path, or cutting in a new drainage channel are all straightforward.

Resin repairs are harder to hide. A damaged area is cut out and fresh material trowelled in, but matching aggregate batch and weathering exactly is difficult. On the other hand, resin needs repair far less often because there are no individual units to settle or shift.

If you know a water main renewal, a new supply or an EV charger installation is coming, block paving handles the disruption more gracefully.

Block paving offers pattern, colour, borders and detail — herringbone, stretcher bond, circles, contrasting soldier courses. It suits traditional Essex properties and allows a drive to be designed rather than simply surfaced.

It is also very common, which cuts both ways: it looks appropriate everywhere and distinctive nowhere.

Resin reads as a seamless gravel surface in a wide range of natural aggregate colours. It looks contemporary and calm, and it suits both modern properties and period ones where a plain, unfussy surface lets the house do the work.

Resin's flat, continuous surface is genuinely better for wheelchairs, pushchairs and bicycles, and it does not carry loose stone into the house. Block paving has a slightly textured surface with joint lines that catch small wheels.

Both can satisfy the front-garden planning rules, but the detail differs. Resin bound over a permeable base infiltrates across its whole area and is inherently compliant.

Standard block paving on a sand laying course is not permeable — the joints are filled with sand and the sub-base contains fines. Permeable block paving is a specific system with wider joints filled with clean grit, an open-graded sub-base and no fines. It is compliant, but it must be specified as such.

A standard block drive can also be made compliant by draining to a soakaway or a permeable border. That works, but it needs designing and, on Essex clay, an adequately sized soakaway.

If avoiding a planning application without additional drainage works is a priority, resin is the simpler route.

Choose block paving if you value repairability, want a patterned or detailed frontage on a traditional property, expect services work across the drive, or are happy with light annual maintenance.

Choose resin if you want the lowest possible maintenance, dislike weeds intensely, have a shaded frontage where moss thrives, want a smooth surface for wheels, or have an existing sound surface that can be used as a base.

A frequent compromise is resin as the main surface with a block paved border and apron. The border provides a solid edge restraint, adds a traditional detail at the road edge, and gives an easily lifted strip if services ever need to cross.

Both are good surfaces. Both fail if the groundwork is wrong. Whichever you choose, the excavation depth, sub-base thickness, compaction and edge restraint matter more than the decision between them.
