Fundo Ligno and Fundo RioLigno, two Wedi shower trays for integration into wooden floors

Like all wedi products, Fundo Ligno and Fundo RioLigno are 100% waterproof, reliable, tested and certified. As a waterproofing expert, wedi makes no technical difference between the installation of a shower tray on concrete or on a wooden floor and offers two dedicated zero projection products!

Wood construction is currently favored by a regulatory framework, the RE2020, which aims to reduce the carbon impact of buildings while continuing to improve their energy performance. However, it is complex to get the CSTB (Centre Scientifique et Technique du Bâtiment) and insurers to approve shower systems on wooden supports, while at the same time, the construction majors are increasingly integrating wood. in their projects.

To meet these regulatory changes and this need, manufacturers must of course both develop appropriate solutions and also try to provide guarantees. This is the case with wedi, all of whose products are compatible with concrete or wood substrates.

By developing two special wood solutions, the manufacturer aims to counter preconceived ideas about this material, to promote the installation of showers in and on wooden structures and to support professionals in the sector by providing its own expertise and guarantees. .

The regulatory context

Wood is highly acclaimed on the construction market. Beyond its aesthetic virtues reminiscent of nature, wood is a biosourced material recognized for its extremely efficient carbon footprint.

The use of wood is growing rapidly in the construction of public buildings and individual housing since it provides an excellent carbon footprint. Moreover, building majors take into account the relevance of this material, such as Bouygues in particular with its subsidiary WeWood which announces the construction of 30% of housing in wood by 2024 in their operations.

Today, the problem with wooden structures lies in their insurability. The CSTB, the technical inspectors and the insurers are quite wary of the watertightness of bathrooms on wooden supports. They fear that in the event of water damage, the leak will affect the wooden structure of the structure and that the damage will then become more serious than on a concrete support.

Added to this is another brake: the question of zero jump. Since July 1, 2021, new homes must be equipped with a zero jump shower, a measure that reinforces the fear of a damaged bathroom.

For wedi, the zero jump has never posed a problem given the mastery acquired over many years on these processes, throughout Europe and North America. In addition, wedi's expertise resides in the control of watertightness and the reliability of its systems, guaranteed for at least 10 years.

The bathroom specialist wishes to reassure professionals and shower installers by offering complete systems that are perfectly compatible with each other and which make it possible to completely create zero projection, 100% waterproof bathrooms.

The majors trust wedi in the context of wooden constructions. They rely on the company's know-how, the support of the wedi technical manager and on their control offices, which discuss with the technical department before carrying out each project. This is particularly the case of the Leco group, a specialist in design and modular construction in wood.

Xavier Jaffray, President of the Leco group, talks about his partnership with wedi:
“Having wedi as a partner is essential for research and development. With the agreement of the control offices, we were able to carry out several operations with wedi on wooden floors. This was only possible because we were able to jointly define a regulatory validation framework for the processes. The wedi solution is more qualitative than normal showers. As a general rule, it is implemented when you want to go upmarket while meeting regulatory constraints. »

Christophe Gay, Kasteliades, also testifies to his choice of wedi solutions in his activity, the renovation of castles to make them high-end holiday residences. “The wedi solutions are perfectly adapted to our needs, whether for easy implementation or for the guarantee of tightness! » « …in castles we often find parquet in all the rooms. We cannot therefore afford to use a joint that would not be reliable over time and end up facing flooding of the floors and lower floors where there are frescoes over 200 years old. »

wedi products suitable for timber constructions

The Fundo Ligno and RioLigno trays have been developed to facilitate the integration of trays in wooden floors, flush, thus eliminating readjustment work.

The installer thus saves considerable time and simply has to cut out the floor area needed to install the tray. In addition, the two products are 100% waterproof which allows them to adapt to wooden floors, supports sensitive to humidity. All wedi trays are tested for leaks at the factory, which gives them high reliability. They are also fully compatible with products from the wedi range which gives them a real advantage.

Fundo Ligno

The Fundo Ligno range of floor-level shower trays, with classic single-point drain, is dedicated to installation on wooden floors, whether on new construction or renovation.

• With 20 mm thickness, it integrates perfectly into the wooden floor, thus avoiding patching work.
• Guaranteed 100% waterproof, it ensures reliability worthy of wedi's expertise.
• Available in square and rectangular versions, it adapts to all designs.

Fundo RioLigno

Like the Fundo Ligno, the rectangular Fundo RioLigno with linear drain was designed to be installed on a wooden floor.

• Available in several sizes, the shower tray measures 25 mm in height, which allows it to be easily integrated into the existing floor.
• In addition, the Fundo RioLigno is compatible with the end strips as well as with the slope profiles of the wedi range.
