Best Hard-Wearing Patio Slabs

If you're looking for patio slabs that can withstand heavy foot traffic, furniture, and weather, here are some of the best options:

  • Porcelain Paving: Porcelain paving is known for its strength, durability, and resistance to stains, scratches, and fading. It is also easy to clean and maintain, making it an excellent choice for high-traffic areas.
  • Granite Paving: Granite is one of the hardest natural stones available, making it an excellent choice for patios that see a lot of foot traffic. It is also resistant to scratches and stains and can withstand extreme weather conditions.
  • Concrete Paving: Concrete is a highly durable material that can withstand heavy use and exposure to the elements. It is also easy to maintain and comes in a variety of colors and textures.

Best Thickness for Paving Slabs

The thickness of paving slabs will depend on the intended use and the weight they will need to bear. For most patios, a thickness of 20-30mm is sufficient. However, if the patio will be used for heavy furniture, vehicles, or equipment, thicker slabs may be necessary.

Do You Put Cement Between Paving Slabs?

It is recommended to use a cement-based mortar between paving slabs to ensure a strong and stable patio. The mortar will fill the gaps between the slabs, preventing them from shifting or moving over time.

Should Patio Slabs Have a Gap?

Yes, it is recommended to leave a gap of at least 10-15mm between paving slabs to allow for expansion. However, certain situations do not require this, such as slabs underneath a shed.

Do I Need a Membrane Under Slabs?

A common question homeowners have when installing patio slabs is whether they need a membrane under the slabs. A membrane is a thin layer of material that's placed between the soil and the slabs to prevent weeds from growing through and to help stabilize the slabs. While not strictly necessary, a membrane can help ensure that your patio remains level and weed-free over time.

Why Do Patio Slabs Come Loose?

Another common issue with patio slabs is that they can come loose over time. This can be caused by a variety of factors, including:

  • Poor installation - If the slabs were not properly installed in the first place, they may come loose over time.
  • Water damage - If water seeps into the soil underneath the slabs and freezes, it can cause the soil to shift and the slabs to become loose.
  • Wear and tear - Over time, the slabs can become worn down from foot traffic and other forms of use, leading to looseness.

To prevent patio slabs from coming loose, it's important to ensure they are properly installed and to maintain them regularly. This includes checking for signs of wear and tear, keeping the area clean and free of debris, and addressing any water damage immediately.

Do You Lay Slabs on Sharp Sand or Building Sand?

When installing patio slabs, it's important to use the right type of sand. There are two main types of sand used in patio installation: sharp sand and building sand. Sharp sand is a coarse, gritty sand that's best used as a base layer. Building sand is a finer sand that's better for filling gaps between the slabs. Typically, it's recommended to use a combination of both sharp sand and building sand when installing patio slabs. This helps ensure a stable base and provides a secure foundation for the slabs.
