For a terrace on a sand bed, we recommend the use of concrete or natural stone slabs. These types of slabs are durable and weather-resistant. They also offer excellent stability and attractive aesthetics.
It's important to choose slabs suited to the type of use planned for the terrace. If the terrace is to be used intensively, it's best to opt for thicker, more resistant slabs. This will ensure long-term durability and avoid problems associated with premature wear.
When it comes to tile format, there are many options available on the market. Square or rectangular slabs are the most common, but you can also opt for hexagonal or irregular slabs to add a touch of originality to your terrace.
Before laying the tiles, it is essential to prepare the sand bed correctly. This must be levelled and compacted to ensure a stable surface. It is recommended to use a geotextile film underneath the sand bed to prevent weed growth and stabilize the soil.
Once the sand bed has been prepared, the tiles can be carefully laid. It's important to follow the manufacturer's installation instructions, taking care to space the tiles properly and align them correctly. After laying, we recommend filling the joints between tiles with fine sand or gravel to stabilize the whole and prevent unwanted movement.
In conclusion, for a terrace on a sand bed, we recommend using concrete or natural stone slabs suited to the intended use. Proper preparation of the sand bed and careful installation will guarantee a solid, long-lasting terrace so you can enjoy your outdoor space to the full.
How thick is the Pour slab laid on sand?
The question of slab thickness for laying on sand depends mainly on the intended use of the slab and the nature of the soil. In general, a slab thickness of 8 to 10 cm is recommended for slabs laid on sand.
However, there are additional factors to consider. For example, if the slab is to be used for frequent passage of vehicles or heavy machinery, a greater thickness may be required. It is also important to take into account the composition of the soil beneath the sand, as some types of soil may require a greater slab thickness to ensure good stability.
It is therefore advisable to call on a building professional or paving specialist to correctly assess the slab thickness required for your specific situation.
Why put sand under the slabs?
Sand is often used as a base material when laying slabs. Its main function is to ensure good stability and drainage for the slabs.
Stability : Sand creates a solid base beneath the slabs, levelling them properly. It acts as a backfill, preventing the slabs from shifting or settling over time. This guarantees an even, durable surface.
Drainage : Sand also has the ability to allow good water drainage. When it rains, water can seep through the spaces between the grains of sand, preventing puddles from forming on the surface of the slabs. This helps to keep the slabs clean and safe, avoiding the risk of slipping and the accumulation of stagnant water.
In short, the use of sand under slabs ensures their stability and promotes drainage, which is essential for preserving their appearance and long-term durability.
