The crucial importance of the base structure
The durability of your terrace depends less on the surface material than on its base structure. Whether using a concrete slab, adjustable pedestals, or a well-compacted gravel bed, a stable foundation prevents subsidence and cracking. In the canton of St.
Gallen, winter frost can damage poorly drained ground. Therefore, investing in efficient drainage and a solid base is essential.
Rigorous preparation ensures that your investment remains aesthetically pleasing and functional for many years, helping you avoid premature repair costs down the line.
Material selection for the local climate
The local climate imposes significant thermal constraints. For a terrace in Flawil, it is recommended to choose pavers or tiles that are specifically frost-resistant.
Ceramic materials with low water absorption or selected natural stones are particularly well-suited to withstand freeze-thaw cycles. Also, consider the maintenance required for each material, such as composite wood, solid wood, or stone.
Each option offers different benefits regarding aesthetics and weather resistance. Use our RenoIndex tool to compare the costs associated with each type of surface material.
Regulations and permits to consider
While no specific grants are mentioned for these construction works, regularly check for potential aid related to energy efficiency if you are installing outdoor heating or smart lighting systems.
Consulting with the building department beforehand is always good practice to avoid any site interruptions.

The best way is to ensure excellent drainage during construction and choose frost-resistant materials. Make sure the base is properly compacted to prevent water stagnation under the surface covering.
