Why This Season Matters

Winter is the harshest season for driveways. Freeze-thaw cycles force water into hairline cracks, expanding them as it freezes and leaving behind larger voids when it thaws. By the time spring arrives, surfaces that looked fine in October can show significant cracking, crumbling edges, and heaved slabs.

Acting in March or April — once overnight temperatures consistently stay above 5°C — gives repair materials the right conditions to cure properly. Leave it until summer and cracks widen further, weeds take hold, and what was a simple patch job can become a full resurfacing project.

Step-by-Step for Each Task

Filling tarmac cracks: Sweep the crack clean and remove any loose material with a cold chisel. Blow out dust with a foot pump or compressed air. For cracks under 10 mm, apply a brush-in tarmac crack filler and work it fully into the void. For wider gaps, use a cold-lay tarmac repair compound, tamp firmly with a block of timber, and feather the edges level with the surrounding surface. Allow 24 hours before driving over it.

Patching concrete: Cut back any crumbling edges to a clean, sound face using a cold chisel and club hammer — do not leave feathered edges or the patch will de-bond. Dampen the area, apply a concrete bonding agent, then fill with a rapid-setting concrete repair mortar. Trowel flush and cover with polythene sheeting for 24 hours to slow the cure and prevent cracking.

Redistributing gravel: Rake the entire surface to level high and low spots caused by traffic and winter rain wash. Where gravel has spread onto lawns or paths, collect it and return it to the drive. If the surface is visibly thin in areas, top up with matching aggregate. Check that any edge restraints are still upright and firmly fixed — this is the most effective way to prevent future migration.

Pressure washing: Work from the highest point of the driveway downward so dirty water drains away from cleaned sections. Use a wide fan nozzle and keep the lance moving to avoid etching concrete or dislodging block paving sand. After washing, allow the surface to dry fully before applying any sealant or filler, as trapped moisture will prevent adhesion.

Tools and Materials You’ll Need

• Cold chisel and club hammer
• Wire brush and stiff-bristled hand brush
• Tarmac crack filler (brush-in type)
• Cold-lay tarmac repair compound
• Concrete repair mortar (rapid-setting)
• Concrete bonding agent / PVA
• Pointing sand or kiln-dried jointing compound (for block paving)
• Weed killer or path-and-drive weedkiller gel
• Pressure washer with fan nozzle
• Rake and garden broom
• Tamping block (short offcut of timber)
• Polythene sheeting (for curing concrete patches)
• Safety glasses and work gloves
• Kneeling pad

Common Mistakes to Avoid

• Repairing too early in the season: Applying tarmac fillers or concrete mortars when overnight temperatures are still dropping below 5°C causes the material to cure too slowly or crack as it freezes. Check a five-day forecast before starting.
• Skipping surface preparation: Brushing filler into a dusty or wet crack without cleaning it out first is the single most common reason patches fail within weeks. Clean, dry, and sound edges are not optional.
• Pressure washing before filling cracks: Forcing water deep into open cracks and then immediately applying filler traps moisture, which leads to de-bonding and frost damage in the following winter. Always fill first, then wash around the repair once it has cured.
• Feathering concrete patch edges: Thin edges on concrete repairs crack and lift quickly under tyre weight. Always cut repairs back to at least 10–15 mm depth around the perimeter before patching.
• Ignoring drainage: Blocked gullies and channels cause standing water that accelerates surface deterioration. Clearing them in spring is as important as the visible surface repairs.
