AquaDrain® BF-FLEX
Drain grate that can be positioned like a ramp – continuously variable height adjustment and can be shortenedInformation
AquaDrain® BF-FLEX drain grates have a special screw foot system with which the drain grate can be positioned at an angle, like a ramp. In combination with the AquaDrain® surface drainage mats, which provide outstanding drainage, threshold-free and easy-access door thresholds on balconies and terraces are no longer a problem.
Advantages
-
Ramp-like, continuous adjustment system makes easy-access thresholds possible - without the risk of accumulated water.
The special ball head screw foot system makes inclined, ramp-like setting of up to 6 % possible. This means that the door element can be installed at a higher level, with the upper edge of the waterproofing lying above the upper edge of the covering. -
The integral dirt trap protects against fouling.
The trap prevents dirt from falling through the drain grate, therefore guaranteeing the long-term drainage performance of the drain grate and the surface drainage . - Simple, precise alignment at covering level using screw feet that can be continuously adjusted from above.
-
Maximum drainage performance due to drain grate open at the bottom combined in a system with AquaDrain® drainage mats.
Guarantees maximum drainage capacity without water accumulation. Façade and surface water is drained in an unimpeded and reliable way beneath the covering. -
Easy and variable shortening on site, saving time and money.
Thanks to adjustable double sliding feet and special frame geometry, time-consuming and expensive customised designs are no longer required; the feet also serve to connect the grids with one another.
