Block Paving

How to Care for Your Concrete & Clay Block Paving

Block paving is a stylish and durable choice for driveways, patios, and pathways. Whether made from concrete or clay, it provides a strong and visually appealing surface for outdoor spaces. However, like any external material, block paving needs the right care and maintenance to keep it looking its best. Using the wrong cleaning products can lead to damage, discolouration, and surface wear, so understanding the proper cleaning and protection methods is essential.

Understanding Block Paving – Concrete vs. Clay

Block paving is available in two main materials:

Concrete Blocks – Made from cement, sand, and aggregates, these blocks are popular due to their affordability and variety of colours. However, they can be prone to surface wear and fading if not maintained properly.
Clay Blocks – Manufactured from natural clay, these blocks are highly colour-retentive and durable. While they resist fading, they tend to be more porous, meaning they can absorb moisture and stain more easily than concrete.

Both materials require regular cleaning and sealing to prevent deterioration from stains, algae growth, and weathering.

Why Using the Wrong Cleaners Can Damage Block Paving

Not all cleaning products are safe for block paving. Some household and patio cleaners contain harsh acids or solvents, which can negatively affect the surface by causing:

❌ Surface Erosion – Some chemicals can weaken concrete blocks over time, making them more susceptible to crumbling.
❌ Fading & Discolouration – Aggressive cleaners may strip colour from both concrete and clay pavers, leading to a patchy appearance.
❌ Efflorescence Issues – Some chemicals can worsen salt deposits (efflorescence), causing white stains on the surface.

To avoid these issues, we do not recommend using vinegar, acids, ammonia-based cleaners, or general-purpose patio cleaners. While they may seem effective, they can cause long-term damage to the paving.

Recommended Cleaning & Protection for Block Paving

To keep concrete and clay block paving looking its best, use a cleaner that is specifically designed for block paving. The right cleaner will:

✔ Effectively lift dirt and stains without degrading the surface.
✔ Be safe for regular use without causing erosion or fading.
✔ Work with the natural composition of the paving rather than against it.

Sealing for Long-Term Protection

In addition to cleaning, sealing block paving is essential for protecting against moisture absorption, stains, and surface wear. A high-quality sealer will:

✔ Repel water, oil, and dirt, preventing deep stains.
✔ Resist moss and weed growth, keeping the joints cleaner for longer.
✔ Enhance durability, protecting against foot and vehicle traffic.
✔ Preserve colour and prevent fading, particularly in concrete blocks.

Sealing should be carried out every 12–24 months, depending on exposure to weather and foot traffic. A well-sealed surface is easier to maintain and prevents dirt and stains from penetrating the paving, making future cleaning much simpler.

Why Choosing the Right Products Matters

We only recommend cleaning and sealing products that are specifically designed for block paving because they:

✅ Provide effective results without causing surface damage.
✅ Extend the lifespan of the paving by reducing wear and erosion.
✅ Keep surfaces looking fresh, clean, and protected from stains.

Many off-the-shelf patio cleaners or household chemicals can do more harm than good. That’s why using purpose-made products is the best way to clean and protect block paving without the risk of accidental damage.

Block paving is a significant investment, and with proper maintenance, it will stay looking attractive and durable for years. By choosing the right cleaning and sealing products, you can keep your paving safe from stains, weathering, and discolouration.

Taking the time to use the correct products ensures your concrete or clay paving remains in the best condition possible—without the risk of damage from unsuitable cleaners.
