Natural Stones vs. Porcelain Paving Slabs: Which to Prefer
While choosing tiles for outdoor spaces like a garden, homeowners mostly get confused between traditional natural stone pavings such as sandstone, granite, and limestone, and porcelain paving slabs. Natural stone paving is valued for its authentic texture, natural coolness underfoot, and eco-friendly composition. In contrast, porcelain paving is non-porous, stain-resistant, and far easier to maintain.
While natural stone needs regular sealing to protect against algae and frost damage, porcelain paving retains its finish and colour for years with minimal upkeep, making it a more practical choice for modern UK gardens..
If you love the earthy charm of natural stone but want something low-maintenance, Travertino Grey Porcelain Paving captures that same natural beauty while resisting moss, stains, and fading. You get the functionality and durability porcelain is known for, without constant upkeep.
7 Steps to Prepare Your Garden for Porcelain Paving Slabs
Preparing your garden for paving slabs involves several key steps to ensure a stable, level, and durable base for your paving. Here's a simple guide:
Clear the Area:
Remove any grass, plants, rocks, or debris from the area where you plan to lay the slabs.
Excavate the Ground:
Dig down to a depth of about 50-100mm (depending on the thickness of your slabs), ensuring you account for both the base layer and the slabs' thickness.
Compact the Subsoil:
Use a compactor to level and compact the soil to create a solid foundation. This helps prevent shifting or settling later.
Add a Base Layer:
Lay a layer of crushed stone or gravel (around 40-50mm), then compact it. This helps with drainage and stability.
Install a Sand or Mortar Bed:
Spread a layer of sharp sand or a mortar mix over the compacted base to create a smooth, level surface for the slabs.
Level the Surface:
Ensure the surface is even using a spirit level. This step is crucial to prevent uneven paving and water pooling.
Mark the Layout:
Before laying the slabs, plan and mark the layout of your paving. This ensures a neat and organized installation.

Frequently Asked Questions!
1. Why do my porcelain tiles keep cracking when I cut them?
Porcelain is a dense and hard material, so improper cutting can lead to cracks. Use a wet tile saw or bridge cutter for clean, precise cuts. Always follow manufacturer recommendations and take safety precautions when cutting 20mm slabs.
2. Can you put porcelain tile directly on concrete?
While it’s technically possible, a stable and level base is essential for long-lasting results. For outdoor spaces, we recommend preparing the ground with a compacted base layer and sand or mortar bed to prevent shifting and water pooling.
3. Does porcelain break easily if dropped?
Porcelain is highly durable but can chip or crack if heavy objects fall on its edges. 20mm outdoor slabs are thicker and more resistant than standard indoor tiles, making them suitable for patios, walkways, and driveways.
4. What thickness do porcelain tiles come in?
Outdoor porcelain paving slabs are available in multiple thicknesses, typically 20mm, 16mm, or 12mm. 20mm slabs are ideal for gardens, patios, and driveways due to their strength and durability.
5. Are 16mm porcelain tiles good for outdoor use?
16mm tiles can work for lighter traffic areas such as garden pathways or patio seating zones. However, for high-traffic areas or driveways, 20mm porcelain slabs are recommended to ensure longevity and structural integrity.
6. What is the 3-4-5 rule for tiling?
The 3-4-5 rule is a simple method to ensure your paving layout is square and aligned. Measure 3 units along one edge, 4 units along the perpendicular edge, and 5 units along the diagonal. This helps avoid uneven or skewed tile placement.
7. Can porcelain tiles be used on sloped surfaces?
Yes, but proper slope design is important for drainage and safety. Ensure the slope is consistent and that anti-slip 20mm porcelain slabs with an R11 rating are used to prevent slipping in wet conditions.
8. What are the environmental impacts of porcelain paving?
Porcelain production requires high temperatures and energy, which increases its carbon footprint compared to natural stone. On the positive side, porcelain is highly durable and low-maintenance, which reduces replacement frequency and long-term environmental impact.
