- Better anchorage of waterproofing systems
- Body made of polypropylene with non-woven fabric, die-cast in a single piece
- Base provided with projections to prevent accumulation of moisture below the vent
- Frost-proof
The laying density should be determined according to the level of moisture present in the stratigraphy of the surface. The maximum working surface area for each vent is 20 m²
If there is an insulation layer below the sheath, skip points 2 and 3 from the application procedure
Indispensable for waterproofing surfaces with residual moisture
Helps the moisture that has accumulated below a liquid waterproofing membrane to escape
Installation instructions
Make sure the surface is free of dust, loose or detached parts, oil, grease and any dirt in general that could affect adhesion
Cement surfaces:
- 1) Before positioning the vent, make a hole on the surface (equal to the diameter of the evaporation flue, approx. 65 mm) that is approx. 3/4 cm deep. When positioning the vent, make sure that the hole made corresponds to the hole in the rod. Take care not to damage any underlying waterproofing
- 2) Attach the vent to the underlying surface by spreading a bed of mortar or cement-based adhesive only in the area of the non-woven fabric, leaving the base of the plastic rod free to avoid obstructing the passage of steam; put the vent in position
- 3) Secure the vent to the underlying surface with three steel nails planted on the polypropylene base of the rod
- 4) Smooth and coat the surface of the vent with mortar or cement-based adhesive, making sure to create the appropriate inclines to avoid stagnation zones at the base of the vent. Wait for the mortar or cement-based adhesive to dry completely, then lay the liquid waterproofing membrane
Tiled surfaces:
- 1) Remove a tiled area so as to allow optimal positioning of the base of the vent
- 2) After performing the operations in point 1, make a hole on the surface (equal to the diameter of the evaporation flue, approx. 65 mm) that is approx. 3/4 cm deep. When positioning the vent, make sure that the hole made corresponds to the hole in the rod. Take care not to damage any underlying waterproofing. Attach the vent to the underlying surface by spreading a bed of mortar or cement-based adhesive only in the area of the non-woven fabric, leaving the base of the plastic rod free to avoid obstructing the passage of steam
- 3) Secure the vent to the underlying surface with three steel nails planted on the polypropylene base of the rod
- 4) Fill the missing thickness with mortar or cement-based adhesive up to the level of the old floor, making sure to create the appropriate inclines to avoid stagnation zones at the base of the vent
- 5) Wait for the mortar or cement-based adhesive to dry completely, then lay the liquid waterproofing membrane
Surface: bituminous sheath (resting on a concrete surface)
- 1) Etch the sheath with a cutter over an area corresponding to the plastic base of the vent so as to allow optimal positioning. If using a double sheath, also etch the second layer underneath
- 2) After performing the operations in point 1, make a hole on the surface (equal to the diameter of the evaporation flue, approx. 65 mm) that is approx. 3/4 cm deep
- 3) When positioning the vent, make sure that the hole made corresponds to the hole in the rod. Secure the vent to the underlying surface with three steel nails planted on the polypropylene base of the rod
- 4) Weld a portion of a new bituminous sheath that is larger than the collar in non-woven fabric
- 5) Allow the sheath to cool, then lay the liquid waterproofing membrane
