Block Paving & Driveway Aftercare
Practical advice for cleaning block paving, controlling weeds, maintaining jointing sand and caring for your driveway throughout the year.
Caring for Your Block Paving & Driveway
Regular sweeping, careful cleaning and maintaining the jointing sand will help keep your block-paved driveway looking its best and performing properly.
Block paving is designed to withstand regular vehicle and pedestrian use, but oil, weeds, algae, displaced sand and accumulated debris should be dealt with before they become established.
The Essentials
Sweep Regularly
Remove leaves, soil and loose debris before they collect within the joints or encourage weeds and organic growth.
Maintain the Jointing Sand
Jointing sand helps lock the blocks together. Replace sand that has been removed through cleaning, weather or regular use.
Clean Spills Promptly
Blot oil, fuel, grease and coloured liquids quickly before they penetrate or spread across the paving.
Control Weeds Early
Remove young weeds before their roots become established and replenish any missing jointing sand afterward.
How to Clean Block Paving
Gentle, regular maintenance is safer than allowing dirt, algae and weeds to become deeply established before using aggressive treatment.
Clear the Driveway
Move vehicles, bins, plant pots and other items so the complete area can be inspected and cleaned safely.
Sweep Thoroughly
Remove loose stones, leaves, soil and debris using a suitable outdoor brush, including material collected around the edges.
Remove Young Weeds
Carefully remove visible weeds and as much of the root as possible without scraping or damaging the blocks.
Apply a Suitable Cleaner
Use warm water with a mild detergent or a product specifically approved for the type of block paving installed.
Brush the Surface
Agitate the cleaner using a stiff non-metallic brush, working over a manageable area at a time.
Rinse and Inspect
Rinse thoroughly, allow the paving to dry and inspect the joints for any sand displaced during cleaning.
The Sand Is an Important Part of the Driveway
The kiln-dried sand between block paving is not simply decorative. It helps lock the blocks together, supports their edges and contributes to the stability of the complete paved surface.
Cleaning, heavy rainfall and general use can gradually reduce the level of sand. Low or empty joints should be replenished using jointing sand suitable for the paving and installed during completely dry conditions.
Protecting Your Driveway
- Clean oil, fuel and vehicle-fluid leaks as quickly as possible.
- Avoid turning vehicle wheels repeatedly while completely stationary.
- Do not drag skips, machinery or heavy metal objects over the blocks.
- Use protective boards beneath skips or heavy temporary equipment.
- Remove wet leaves before they begin staining the paving.
- Keep channel drains, gullies and drainage outlets clear.
- Remove weeds before they become deeply rooted.
- Replace jointing sand displaced through cleaning or regular use.
Protect the Blocks and Jointing Sand
Aggressive pressure washing can mark the surface, damage block edges and remove a significant amount of jointing sand. Routine brushing and rinsing should be attempted first.
If pressure washing is appropriate, use a wide fan setting, maintain a sensible distance and keep the lance moving. Do not direct concentrated pressure into the joints or drainage channels.
Allow the driveway to dry completely after cleaning. Any displaced jointing sand must then be replaced before the area returns to normal vehicle use.
Choosing the Correct Treatment
Always use a cleaner confirmed as suitable for the exact paving installed. Follow its instructions and test it on a small, discreet area before treating the complete driveway.
Mud & General Dirt
Allow heavy mud to dry, sweep away the loose material and clean the remaining marks using warm water and a suitable mild detergent.
Oil & Vehicle Fluids
Absorb fresh spills without spreading them. Established marks may require a specialist oil remover approved for concrete block paving.
Tyre Marks
Begin with a suitable mild detergent and non-metallic brush. Persistent marks may require a manufacturer-approved specialist cleaner.
Leaves & Organic Marks
Remove the source and gently clean the area. Established tannin marks may require a concrete-safe organic stain treatment.
Algae, Moss & Lichen
Use a treatment confirmed as suitable for block paving. Protect nearby planting and rinse the area thoroughly afterward.
Rust or Metal Marks
Remove the source and seek product-specific advice. General acids can permanently alter the colour and finish of concrete blocks.
Replacing Displaced Jointing Sand
The paving and joints must be completely dry before new kiln-dried jointing sand is applied. Damp conditions can prevent the sand from reaching the full depth of the joints.
Spread suitable jointing sand over the dry paving and sweep it diagonally across the blocks until the joints are properly filled. Remove excess material from the surface afterward.
If large areas repeatedly lose sand, blocks have become loose or the joints cannot be filled properly, contact Team Bespoke before continuing.
Why Weeds Can Appear Between the Blocks
Weeds commonly develop when airborne seeds settle within soil, dust and organic debris that has accumulated at the surface of the joints. Their appearance does not normally mean that weeds have grown through the full driveway construction.
Regular sweeping, early weed removal and keeping the joints properly filled will reduce the conditions in which weeds become established. Shaded or damp areas may also require periodic algae and moss treatment.
When Should Jointing Sand Be Replaced?
Inspect the driveway after cleaning and periodically throughout the year. Early maintenance helps prevent loose blocks and damage around their edges.
After Pressure Washing
Pressure washing frequently removes jointing sand. Allow the driveway to dry completely before checking and refilling the joints.
When Joints Look Low
Replenish sand when it has dropped noticeably below the block edges or gaps are beginning to appear.
After Weed Removal
Removing established weeds may also remove jointing material. Refill the affected joints once they are clean and dry.
What to Avoid
Brick acid, acidic cleaners or harsh unapproved chemicals.
Mixing cleaning products or applying one treatment over another.
Wire brushes, metal scrapers or highly abrasive cleaning tools.
Concentrated pressure washing directly into the paving joints.
Leaving joints empty after cleaning or established weed removal.
Dragging skips, machinery or heavy objects across the surface.
Allowing oil, fuel or vehicle fluids to remain untreated.
Attempting to repair loose or sunken blocks without an inspection.
Seasonal Driveway Checklist

Maintenance Issue or Installation Concern?
Routine dirt, weeds, algae, moss, staining and gradual jointing-sand loss are normally maintenance matters. If you notice widespread movement, significant sinking, persistent drainage problems or blocks becoming repeatedly loose, submit a report for review.
Important: This guide provides general aftercare advice. Always follow the instructions supplied by the paving, jointing-sand and cleaning-product manufacturers. Test products on a small, discreet area and never mix chemical treatments. If you are unsure, contact Team Bespoke before proceeding.
