FAQs

What is the best way to clean granite paving slabs?

Regular cleaning involves sweeping away debris and washing with water and a stiff brush. For tougher stains or algae, use a pH-neutral cleaner designed for natural stone, followed by a thorough rinse. Avoid acidic or abrasive cleaners.

Can I use these slabs in a small garden?

Yes, the large format can make smaller gardens appear more expansive and contemporary. However, consider the scale of other garden elements to maintain balance.

What is efflorescence and how do I prevent it?

Efflorescence is a natural salt deposit that can appear on the surface of concrete and stone. It's usually harmless and can be cleaned with a specific remover. Sealing the stone after installation and periodically can help minimize its appearance.

Do I need to seal granite paving slabs?

Sealing is recommended, especially shortly after installation and periodically thereafter. It helps protect against staining and can reduce the likelihood of efflorescence, enhancing the longevity and appearance of the stone.

What type of base is recommended for laying these slabs?

A robust and stable base is crucial. This typically involves a compacted layer of hardcore (e.g., MOT Type 1) followed by a sharp sand bedding layer of approximately 40-50mm.

Are these slabs slippery when wet?

The textured top surface provides a degree of grip, making them less slippery than smooth finishes. However, like all paved surfaces, caution should be exercised when wet.

Troubleshooting

Paving appears uneven after installation

Check the sub-base for stability and ensure each slab is properly bedded. Minor adjustments can be made by carefully lifting and re-bedding, or by adding or removing bedding material.

White powdery substance on the surface (efflorescence)

Efflorescence is a natural process in concrete and stone products. Clean the affected area with a specialized efflorescence remover and apply a suitable sealant to prevent recurrence.

Slabs are difficult to handle or cut

Due to their size and weight, use appropriate lifting aids or get assistance. For cutting, use a diamond-tipped wet saw suitable for stone.

Moss or algae growth

Regular sweeping and washing with water should suffice. For persistent growth, use a patio cleaner specifically designed for natural stone, ensuring it's suitable for granite.

Pros and Cons

Pros

  • Achieves a highly modern and minimalist aesthetic.
  • Durable natural granite construction for longevity.
  • Large slab size minimizes grout lines, enhancing visual flow.
  • Textured surface provides practical slip resistance.
  • Consistent grey colour integrates well with contemporary garden designs.

Cons

  • Large size requires careful handling and potentially specialized installation equipment.
  • Requires meticulous sub-base preparation due to slab dimensions.
  • Granite can be prone to efflorescence (white powdery deposits) if not properly sealed or maintained.
  • The minimalist design might not suit traditional garden styles.

Setup, Compatibility & Care Instructions

Setup: Proper installation is crucial for the longevity and appearance of your granite paving. A well-prepared, stable sub-base is essential, typically a compacted layer of MOT Type 1 hardcore followed by a sharp sand bedding layer. Lay the slabs on this bed, tapping them gently into place to ensure a level surface. Use a string line to maintain straightness, especially with the large format slabs. Ensure adequate drainage by incorporating a slight fall away from buildings.

Compatibility: This paving is compatible with most modern garden designs. It pairs well with contemporary fencing, minimalist planters, and sleek outdoor furniture. Ensure any sub-base materials are inert and won't react with the granite.

Care: Clean the paving regularly with water and a stiff brush to remove dirt and moss. For stubborn stains or algae, use a specific stone cleaner recommended for granite, following the manufacturer's instructions. Avoid using harsh acidic or alkaline cleaners. It is advisable to seal the granite after installation and periodically thereafter to help prevent staining and efflorescence. Check for any efflorescence (white powdery deposits) and address it with a suitable efflorescence remover and sealant.
