Block Paving
How to Care for Your Concrete & Clay Block Paving
Block paving adds strength and style to driveways, patios, and paths. Concrete and clay blocks both create a solid, attractive surface.
To keep them looking great, clean and maintain them with care. The wrong products can stain, wear, or damage the surface.
Understanding Block Paving – Concrete vs. Clay
Block paving comes in two main types: concrete and clay.
- Concrete blocks use cement, sand, and gravel. They’re affordable and colourful but can fade or wear if not protected.
- Clay blocks come from natural clay. They hold their colour well but soak up moisture more easily, causing stains or algae.
- Both need regular cleaning and sealing to stay clean, strong, and weather-resistant.
Why the Wrong Cleaners Can Harm Block Paving
Many cleaning products contain strong chemicals that can damage paving.
Using them may:
❌ Weaken the surface, especially on concrete blocks over time
❌ Strip colour from both clay and concrete, leaving faded or patchy areas
❌ Trigger efflorescence (white salt stains) by reacting with minerals in the blocks
Avoid vinegar, ammonia, bleach, and basic patio cleaners. They might seem effective, but they often do more harm than good.
How to Clean and Protect Block Paving Properly
Use a cleaner made for block paving. The right cleaner will:
✔ Remove dirt and stains without harming the surface
✔ Work safely on both concrete and clay
✔ Avoid erosion, fading, and other long-term problems
Why Sealing Is Just as Important
Cleaning helps short term—but sealing protects long term. Sealers block moisture, reduce wear, and make cleaning much easier.
A proper block paving sealer will:
✔ Repel water, oil, and dirt to prevent stains
✔ Stop moss and weeds from growing in the joints
✔ Make the blocks more durable under traffic
✔ Lock in the colour, especially for concrete paving
Reapply your sealer every 1 to 2 years, depending on weather and how much traffic the area gets.
Why the Right Products Make All the Difference
Only use cleaners and sealers made for block paving. They:
✅ Clean well without damaging the blocks
✅ Extend the life of your paving by resisting erosion
✅ Keep your paths and driveways looking clean and well cared for
Many store-bought patio cleaners contain harmful acids or chemicals. Stick with products made for block paving to avoid costly damage.
Look After Your Paving the Right Way
Block paving is an investment worth protecting. Clean it often, seal it well, and always use safe products for concrete or clay. Doing this helps your paving stay strong, clean, and looking great for many years.
