Installation of the veranda
Preparation of your site
The preparation of the site is a determining phase for the good progress of your project. It influences the quality of execution and its durability. Your satisfaction will certainly depend on it!
Rainwater will run off the roof of the shelter to the ground of your terrace or to the horizontal support on which the shelter is placed. It will then naturally follow the slopes of your terrace. The patio cover is not designed to prevent this. Therefore, we invite you to prepare your deck according to the following recommendations (non-exhaustive list):
- Provide a deck slope of 1 to 2% to promote drainage to the outside of the shelter
- Provide a draining soil to allow rainwater to infiltrate into the ground
- Provide a slight curb or tile “stub” along the runway inside the shelter
- Provide a small gutter inside and along the raceway inside the shelter
- Upon your request, we can install a small lacquered aluminum strip on the floor inside your shelter to reduce the risk of runoff towards the interior. This operation proposed by VERANDAIR® does not offer any guarantee of results.
Finally, in case of heavy rain, you should let the water follow its natural path. You should avoid placing cloths along the bottom rails of the shelter. By capillary action, these cloths will soak up water and amplify the phenomenon of water infiltration inside your shelter.
When preparing your deck, make sure you use materials that are exclusively intended for outdoor use. Do not use untreated wood or parquet flooring.
Fixing of your shelter – pergola
The framework of our patio shelters and pergolas is made of “light” aluminum structures. They are designed to support a snow weight of 45kg/m2 and to withstand a maximum wind speed of 100km/h.
The maximum snow load is equivalent to the surface of the shelter multiplied by the weight of the snow. For example, a 20m2 shelter can support a maximum load of 900kg (20m2 x 45kg). For information, the weight of snow can vary from 150 to 300 kg/m3 depending on its density. Packed snow can reach 500km per m3. It is therefore essential to remove snow from your shelter – pergola when the layer of snow is 9-10cm thick. It is also possible, to avoid snow accumulation, to maintain a constant temperature of 12°C inside the shelter.
In order to withstand such loads, the shelter or pergola must be anchored to its ground attachment points and/or must be firmly attached to its wall support. Your shelter is equipped with solid anchors all around its periphery. These anchors will be connected to long metal pegs inserted in the ground of your terrace.
In order to allow the anchors to be fixed, you must ensure a solid reinforced concrete base (free of electrical cables) either by means of a sill at least 15 cm thick around the entire perimeter of the shelter or by means of concrete blocks of 30 cm per cube.
WARNING : VERANDAIR® is not competent to probe or assess the nature of the ground where the shelter will be installed and/or to probe or assess the nature of the wall support (invisible) where the shelter or the pergola will be installed.
You will have to inform us as precisely as possible and in writing (on the plans of the technician during the technical visit), the location of any invisible obstacles located in the ground or walls (electrical cables, water pipes, oil, gas, etc.). Underfloor heating is strongly discouraged.
Electrical equipment in the patio cover
In order to guarantee your safety inside your patio cover, only electrical appliances and other equipment with a minimum IP64 protection rating (international standard) are allowed inside the patio / pool cover and your pergola.
Furniture and other fittings in the terrace shelter
Only outdoor furniture and materials intended for outdoor use are suitable for your patio/pool house and pergola.
Never place furniture or other accessories against the windows.
Purchase an insurance policy
We recommend that you purchase an insurance policy for your enclosure to protect you against storm, snow, hail, natural disasters and vandalism. Generally, this is an extension of your home insurance. In case of doubt, we invite you to contact your insurer before the installation.
What are the administrative procedures for installing a VERANDAIR® patio cover, pergola or pool cover in the Walloon Region ?
The terrace shelter is not designed to be equipped with permanent heating. The aluminum profiles that make up the shelter are not equipped with thermal bridge breakers. It is therefore considered as an Adjacent Non-Heated Space (ANHS) that is not habitable and is not subject to the PEB type of energy regulation.
Whether attached or detached, the placement of awnings, solar tents or aluminum shelters for a terrace located at ground level is exempt from planning permission and does not require the mandatory intervention of an architect under these conditions* :
Location: on a yard or in a garden. Maximum height: 3.50 m
Maximum total surface area of all these facilities: 40.00 m2
Implantation : at least 2.00 m from the common limits
No conditions related to materials
Telescopic pool enclosures are exempt from planning permission and do not require the intervention of an architect if they do not exceed the maximum height of 3.50 m, a surface area of 75 m2 and if they are located at least 3.00 m from the common boundaries**.
To be on the safe side, we recommend that you ALWAYS ask your administration for more information.
