Positioned below a floor slab (with membranes/barriers), the sump provides a passive gas exit route via a ventilation stack. The stack is terminated above the roof finish with a tile/Slate external roof ventilator. The reception sump may service up to 250m2 floor area, positioned in the most central location to promote even/optimum evacuation. Inhalation apertures and inlet/outlet portholes permit spur connection to adjoining sumps or horizontal extraction should the size or layout of the property dictate.
Please note that these product properties are not a replacement for the manufacturer's literature and it is always recommended that Cavity Trays is consulted before specifying.
