Block paving is one of the most popular driveway and patio surfaces in the UK. It looks fantastic when new, but without proper maintenance, it can quickly deteriorate. Here's our comprehensive guide to keeping your block paving in top condition.
Why Does Block Paving Get So Dirty?
Block paving is particularly susceptible to dirt and organic growth due to its construction:
- Porous surface: Most block paving materials absorb moisture, creating ideal conditions for algae and moss.
- Joint gaps: The sand-filled joints between blocks are perfect breeding grounds for weeds and moss.
- Texture: The textured surface traps dirt, leaves, and debris more easily than smooth surfaces.
- UK climate: Our damp, mild winters provide ideal conditions for organic growth year-round.
The Professional Block Paving Cleaning Process
At Leicester Jet Washers, our block paving cleaning follows a thorough multi-step process:
1. Pre-Treatment
We apply a specialist biocidal treatment to kill algae, moss, and lichen at the root. This is left to dwell for the optimum time before washing begins.
2. Weed Removal
All weeds growing between joints are removed before pressure washing. This ensures the joints can be properly cleaned and re-sanded.
3. High-Pressure Washing
Using commercial-grade rotary surface cleaners, we systematically clean every block at the correct pressure for your specific paving type. Rotary cleaners provide an even, streak-free finish that hand-held lances simply cannot match.
4. Joint Re-Sanding
After cleaning, we sweep kiln-dried sand into the joints. This stabilises the blocks, inhibits weed growth, and gives a finished, professional look.
5. Optional Sealing
For maximum protection, we offer block paving sealant application. This enhances the colour of your blocks, provides a protective barrier against stains and organic growth, and makes future cleaning easier.
How to Maintain Your Block Paving Between Professional Cleans
- Regular sweeping: Sweep leaves and debris weekly to prevent them decomposing and encouraging algae.
- Weed treatment: Treat emerging weeds with a patio weed killer before they establish.
- Stain removal: Clean oil spills promptly with a degreaser to prevent permanent staining.
- Drainage check: Ensure water drains away properly — standing water accelerates algae growth.
Common Block Paving Cleaning Mistakes
If you're considering a DIY approach, avoid these common mistakes:
- Too much pressure: Excessive pressure can blast out joint sand and damage the block surface.
- Using bleach: While tempting, household bleach can discolour blocks and harm nearby plants.
- Neglecting re-sanding: Washing without re-sanding leaves joints vulnerable to weeds and can cause blocks to shift.
- Ignoring drainage: Washing debris into drains can cause blockages.
