How do you waterproof a wooden deck: expert advice
If you have opted for the timeless elegance of a wooden deck, you are in the right place. Be warned, though: protecting the wood from moisture is crucial to guaranteeing its durability. A poorly waterproofed deck can quickly succumb to the assaults of time and weather. In this article, we will give you expert advice for waterproofing your precious wooden deck.
Why is waterproofing paramount for a wooden deck?
Whether you are considering a ground-level deck or a roof deck, waterproofing is the key to the longevity of your investment. Unlike traditional slopes, the flat surfaces of decks leave less room for water to run off naturally. That is why water infiltration can cause major problems. On a ground-level deck, water that is not drained away can compromise the stability of the structure and accelerate its ageing. For a roof deck, the stakes are even higher. As well as protecting the deck itself, adequate waterproofing prevents potential damage to the walls and the ceiling below.
The key to waterproofing: choosing the right material
The choice of material for waterproofing is essential. Bituminous strips prove to be a reliable solution. They are laid on the joists, providing a barrier between the wood and moisture. These strips consist of a roll of bitumen with a polyester reinforcement. Elastomeric bitumen protects effectively against air, rainfall and infiltration.
Steps for waterproofing your wooden deck
1. Apply the waterproofing membrane
Start by applying a waterproofing membrane. A bituminous roll or calandrite are excellent choices. These materials will form a first line of defence against moisture.
2. Lay the wooden structure
Once the membrane is in place, install the wooden structure. Adjustable pedestals on a waterproofing membrane are recommended. This double structure prevents the wood from touching the ground directly, thereby avoiding moisture-related damage.
3. Apply the bitumen strips
The bituminous strips come into play at this stage. Stick them onto the joists, forming a barrier against water infiltration. This crucial step guarantees the protection of the wood.

4. Put the final covering in place
Lay the final covering. Install the wooden boards carefully chosen for their resistance to the weather. These boards form the visible surface of your deck and contribute to its appearance.

Choosing the right finishing material
The finishing covering plays an important role in the waterproofing of your deck. Opt for materials such as wood, composite decking, tiles, natural stone or concrete. These hard-wearing materials will not only offer additional protection, they will also enhance the appearance of your deck.
Calling on a professional for perfect waterproofing
Carrying out adequate waterproofing requires technical know-how. To make sure your wooden deck lasts, entrust this work to a qualified professional. Their expertise will guarantee a precise and rigorous installation, thereby protecting your investment in the long term.

Coverings for a roof terrace: which products should you choose?
Roof terraces are not simply coverings for your house, they can also become attractive living spaces. Guaranteeing the waterproofing of these flat areas does, however, call for a specialist approach. Let us discover together the coverings suited to waterproofing your roof terrace.
The different types of roof terrace
A roof terrace is characterised by its horizontal surface, which sets it apart from traditional pitched roofs. There are two main types of roof terrace:
- Non-accessible roof terrace: Mainly used for apartment blocks, this type of roof is designed to be easily maintained and can support ventilation installations.
- Accessible roof terrace: This type of roof is an extension of your living space. It can be used as a terrace to enjoy the outdoors or even as a garden. It must be built with particular attention to waterproofing in order to avoid leaks.
Coverings for reliable waterproofing
To guarantee effective waterproofing for your roof terrace, it is essential to layer specific roofing materials. Here are a few options to consider:
1. Vapour barrier membrane
A vapour barrier membrane is the first line of defence against moisture. It is installed directly on the roof surface before adding the other layers of insulation and waterproofing.
2. Thermal insulation material
Thermal insulation is crucial for regulating the temperature inside your home and preventing heat loss. Choose a suitable insulating material to ensure optimal thermal insulation.
3. Waterproofing membrane
The waterproofing membrane is the heart of the protection against moisture. The options include EPDM, bitumen, PVC and LWS.
- EPDM (Ethylene Propylene Diene Monomer): A hard-wearing rubber membrane, perfect for flat roofs. It can be laid directly onto an existing surface in the case of a renovation.
- Bitumen: Also known as roofing felt, bitumen is a proven solution. It calls for meticulous installation, with layers heated using a blowtorch.
- PVC (Polyvinyl Chloride): Available in rolls, PVC is a lightweight material that requires careful bonding to guarantee effective waterproofing.
- LWS (Liquid Waterproofing System): A modern solution that involves applying a liquid resin to form a watertight film. LWS can replace bitumen.
4. Finishing covering materials
The choice of finishing covering depends on your aesthetic preferences and on the intended use of your roof terrace. Popular options include:
- Wood: Wooden boards or tiles offer a natural, warm appearance. Be sure to use a weather-resistant wood.
- Composite decking: A blend of wood flour and PVC, this material is durable and easy to maintain.
- Tiles: Tiling is elegant and hard-wearing. There is a variety of patterns and colours to personalise your space.
- Natural stone: Natural stone slabs add a touch of elegance to your roof terrace. They are hard-wearing and durable.
- Concrete: Concrete paving is robust and can be customised to create unique patterns.
- Gravel: Gravel coverings look good and allow effective drainage of water.
Waterproofing and elegance: bring your wooden roof terrace project to a splendid close!
Now that you are familiar with the coverings for reliable waterproofing of your roof terrace, you can take informed decisions for your project. Whether it is a non-accessible terrace or an outdoor living space, the choice of materials and correct installation are essential to avoiding moisture problems. Remember, if you are not sure of your building skills, it is better to call on a qualified professional to obtain durable and attractive results.
