Studded membranes for protection and drainage of below-grade walls.
High resistance to compression due to the octagonal shape of studs.
25 % contact area on basement walls and other foundations structures.
Quick and simple to apply under all weather conditions; easy to cut with a cutter.
Range of accessories suitable for different substrates.
Protection and vertical drainage of exterior basement walls.
Vertical drainage of structural below-grade walls.
Geo-spacer with or without filter geotextile to be applied in all civil works, e.g.:
cut and cover trenches;
drainage system for bottom of reservoir ;
drainage of water infiltration and insulation against moisture inside buildings (curative treatment).
Polypropylene embossed membrane + thermo-welded filtering non woven polypropylene geotextile.
Fonda GTX is horizontally unrolled with the geotextile against the wall and mechanically-fixed along the upper edge:
when applied to concrete, use Fonda gun plugs and nails (\"Hilti\" type, 20 to 27 mm gun nails);
when applied to masonry, use Fonda nails and plugs for concrete blocks and bricks.
When the height of the relevant wall is over 2 m, the Fonda GTX upper roll will overlap the lower roll (horizontal overlaps of about 12 cm).
Vertical overlaps must be about 50 cm wide.
The Fonda finishing profile is fixed on the top edge.
Fonda GTX must be linked at its bottom edge with a drainage peripheral pipe.
The backfilling is completed according to the prevailing local technical standards.
Masonry wall or concrete wall complying with prevailing local technical standards.
