Local guide
A driveway that looks fine in dry weather can reveal its real problem after a spell of rain. The useful first question in Sligo is not “resin or tarmac?” It is “where does the water go, and what is happening underneath the surface?” A new finish cannot correct a fall that points at the house, a base that moves, or an outfall that is already overloaded.
Walk the drive during or soon after rain, without stepping into unsafe areas. Mark puddles, water flowing toward a threshold, soft edges, and places where the surface sheds water onto a footpath or road. Take photographs from the same positions in wet and dry conditions. Note whether the problem is a single low spot, a line along a trench, a failing edge, or water across the whole entrance. That record gives a contractor something more useful than a request for a generic square-metre price.
Sligo County Council's current development-management guidance says planning applications should include proposals for surface-water disposal. It promotes nature-based solutions and sustainable drainage where appropriate, asks applicants to show how rainwater will be managed, and says efforts should be made to reduce impermeable surfacing within a building's curtilage. The same guidance says storm water will not generally be allowed into the foul sewerage network: Sligo County Development Plan 2024–2030, Volume 3, Chapter 33 — Development management standards. The exact planning position depends on the property and proposal, so check with Sligo County Council before work that may need permission.
That guidance does not mean every household needs the same drainage system. A small entrance may need a properly formed fall and a channel at the threshold. A larger or rural drive may need an engineered outfall, a soakaway or another solution that can safely take the water. A permeable surface is not a magic word: if the layers below it are sealed, saturated or poorly compacted, water can still pond. If discharge would cross a public footpath or road, the arrangement needs particular care rather than an improvised pipe.
Only after the water route is understood should the surface be compared. Resin-bound surfacing is often discussed where permeability is part of the brief, but the installer should identify the full build-up and the condition of the base. Tarmac can be a practical choice for a larger area, but it still needs a sound, compacted foundation, an appropriate fall and controlled edges. Block paving can be a full surface or a drainage edge; those are different jobs. Resurfacing may be suitable where the existing base is sound, but it is not a substitute for correcting movement or persistent ponding.
Ask for the quote to state what happens below the visible finish. It should identify the proposed excavation or overlay, sub-base, compaction, falls, edge restraint and outfall. Ask whether the contractor has allowed for soft ground, made ground, restricted access or a utility trench. If the driveway is beside a house, note where downpipes discharge and whether water reaches the wall or threshold. If it is beside a road, ask how the design avoids sending runoff into the public carriageway.
Do not judge a drainage job by its colour sample or a dry-day photograph. A good assessment explains the source of the water and the route it will take after the work. It also distinguishes a maintenance problem from a rebuild: cleaning a channel, repairing an edge and replacing a failed sub-base are not interchangeable tasks. Where the cause is uncertain, pay for a site assessment rather than choosing a surface on price alone.
This guide is practical information, not a planning decision or an installation specification. It does not name a contractor or quote a Sligo price. The independent enquiry route on this site can collect photographs and the location of the problem, then make clear who receives the enquiry and what they are being asked to assess.
