Description

Drainage is an essential step in preventing the stagnation of water in the ground, which can lead to capillary action, as well as cracks caused by water pressure. The quality of the installation is also vital. Poor drainage often has costly and time-consuming consequences. ATE has developed an innovative, tried-and-tested drainage solution: the BATIFIBRE SN4 drain, designed for gravel-free drainage that is quick and easy to install.

Drainage: a crucial and decisive stage

The conventional peripheral drainage method that complies with DTU 20.1 consists of laying a specific bare drain that meets NF P 16-379 standard in the trenches. A geotextile adapted to the type of soil and determined by a professional is installed at the bottom of the trench and covered with gravel as filtering material.

This process requires technical know-how to determine the best materials to use, depending on the nature of the soil (clay, sand, silt) and the lay of the land (slope), so as not to clog the drain, thereby jeopardising the durability and quality of the structure.

As drainage is installed for the life of the building, it is essential to use the right products and install them in accordance with the rules of the trade, which is not always the case.

The advantages of BATIFIBRE SN4: gravel-free drainage

To facilitate drainage and ensure its quality, ATE has designed BATIFIBRE SN4, a gravel-free drainage system. Tried and tested over the last 10 years and recognised by professionals, BATIFIBRE involves no risk of error and is considered to be the most economical, effective and quickest solution to implement.

Recommended for clay soils, BATIFIBRE is a rigid, flat-bottomed Ø 90 drain with a strength of over 4 kN/m², coated with a voluminous fibre.

3-in-1 system: gravel-free and more economical
Increased resistance: SN4 certified
Simple connection with sleeves
Gravel-free installation with technical approval (n°17.2/16-317_V4) and QB certification
Quick slope adjustment thanks to its flat base
BATIFIBRE is a simple, effective and economical solution for installers and consumers alike.

The BATIFIBRE, thanks to its sleeve, can be connected to standard PVC accessories with a female diameter of 100. The BATIFIBRE PVC adaptor sleeve can be used for changes of direction, inspection shafts or cleaning.

FAQ

Protecting buildings from shrink-swell is now possible with solutions that maintain a constant water content in the soil, by waterproofing and draining seepage water, avoiding the consequences for construction. AFITEX and ATE offer a complete waterproofing and drainage solution with Protecterre and Batifibre products.

Please refer to the installation manual for details.

In this type of case, DTU 20.1 recommends positioning the perimeter drain at a distance of around 2 ml from the wall and at a depth of around 80 cm. In this position, the drain limits excess moisture without altering the hydrometry of the soil.

When a building is positioned on a property boundary and drainage on the outside footing is impossible because it would be on the neighbour’s property, drainage can be installed from the inside directly along the foundation under the slab.

Yes, Batifibre works perfectly, and its technology is effective in fine soils (clay, loam).

The fibre is made of polypropylene, a rot-proof material. Used for many years, it does not degrade in the soil.

Absolutely not! BATIFIBRE is not a spreading tube, and does not comply with DTU 64.1.

Yes, Batifibre can be used in a crawl space.

Above a depth of 1.5 m, the drainage system must be combined with either vertical drainage or stepped drains to collect infiltrated water as effectively as possible and limit hydrostatic pressure on the construction.

In fact, it’s important to wait until your soil has dried out to avoid creating a pothole (waterproofing). This applies to all drainage systems (DTU 20.1 and products covered by Technical Approval).

A drain is a perforated pipe used to remove excess water from the ground. It is quite normal for water to come out of the connections without backfilling the drains. It is necessary to backfill to a minimum of 20 cm to check that it is working properly.

The BATIFIBRE drain replaces the traditional drainage complex consisting of (1) a drainage tube, (2) a gravel coating and (3) a filtration and separation geosynthetic. It is therefore not necessary to add gravel to Batifibre drains, as its coating has a drainage function and ensures water circulation. However, the addition of gravel does not harm the proper functioning of the BATIFIBRE, it is just not necessary.

Drainage (evacuation of water already present in your soil) and rainwater evacuation must be in separate networks!

The only possible connection is at the outlet.

The drain pipe is perforated to allow the water to drain into it, whereas the rainwater must be transported for evacuation in smooth PVC pipes.

The risk of creating a single network is that the rainwater will seep directly into your foundations, with all the consequences that implies (infiltration, damp, etc.).
