AquaDrain® BF-FLEX drain grates have a special swivel base system with which the drain grate can be adjusted at an angle – i.e. ramp-like. In combination with the AquaDrain® surface drains, which ensure excellent water drainage, threshold and barrier-free door thresholds on balconies and terraces are no longer a problem.

Advantages:
Ramp-like, infinitely variable adjustability enables barrier-free thresholds without the risk of water backlog. Special ball-head swivel base system allows up to 6% slanted, ramp-like adjustment. This allows the door element to be installed higher so that the upper edge of the seal is above the upper edge of the covering.
Protection against soot through integrated dirt grid. Prevents dirt from falling through the drain grate, thus ensuring the long-lasting drainage performance of the drain grate and drainage. Simple, precise alignment at base level thanks to infinitely adjustable swivel feet from above.
Maximum drainage performance due to drain grate open at the bottom in the system with AquaDrain® drainages. Guaranteed maximum drainage capacity without backwater, drainage of façade and surface water takes place unbraked and safely under the pavement.
Time- and cost-saving cutting to length easily and variably directly on the construction site. Thanks to movable double-foot slider elements and special frame geometry. Time-consuming and expensive custom-made products are no longer necessary; Foot elements also serve as connectors between the grates.
Are trough-forming – and thus comply with DIN standards or flat roof guidelines
