1. The administrative procedures
For a terrace with an area of less than 20 m2 and no more than 60cm high, no authorization is required.
If the height of the terrace exceeds 60cm, a prior declaration of work with the town hall is required. The building permit is essential for a terrace with an area greater than 20m2 and exceeding 60cm in height.
In all cases, it is better to inquire with the services of its town hall, some districts obey special rules.
2. Define the location of the wooden deck
Favor a good exposure to the sun. A location protected from bad weather and wind is preferable. A wooden deck laid under trees will be damaged more quickly.
Avoid building under softwood trees. The terrace can become the 5th room of the house. A terrace placed in extension of a stay or a kitchen will be ideal.
3. Choosing the right wood deck laying technique
Choose a technique for laying wooden decking adapted to the nature of the ground.
- on an existing concrete slab: at regular intervals (every 50 cm), PVC adjustable blocks or shims are placed. They will support the joists on which will be fixed the blades.
- on non-concrete floor: rake the surface to equalize it. Seal blocks at regular intervals (every 50cm). Fix the joists on the blocks, then the boards of the wooden deck. Plan the installation of a geotextile felt to prevent the development of weeds. This technique also makes it possible to install a terrace on a loose and unstable ground.
4. Choose the wood species that will be used to make the terrace
Prioritize certified wood species for resistance to water stagnation, runoff, humidity and U.V. There are different types of wood, classified according to their properties, and the prices are variable. Class 4 wood is recommended for wooden decking, however, Class 3B wood can be used for partially protected decks.
5. Protect the wooden deck to make it last
In order for the wood to retain its original color, it is recommended to protect it with a suitable product (oil, degreaser, saturator ...). Clean the terrace regularly with suitable products. They are designed to eliminate the foam that damages the wood and makes the deck slippery.
