The low-profile WOLFA AquaStop channels without grating are perfectly suited for the drainage of residual or melt water in underground parking and parking decks.The multi-channel drain with its extremely low build of just 25 or 38 mm is made of GRP material and therefore highly resilient. The drainage channel is absolutely resistant to oil, petrol, de-icing salt or frost. The many strong points of GRP material are the basis to our successful AquaStop drainage channel system.
Areas of application: underground parking, multi-level carparks, patios

The low-profile WOLFA channels are ideal in locations with low installation heights. Equipped with a safety seam, this flat channel with a height as low as 58 mm is particularly suited for installation in above-ceiling floor constructions.
Areas of application: patios, underground parking, parking decks, warehouses and shopping arcades
With their installation height of 10 cm, these WOLFA channel types are the ideal supplements for our flat channels and 14 cm PROFI channels.
Areas of application: garages and driveways, linear drainage of facades, entrance areas, stairways, public places and other sealed surfaces
The successor model of our WOLFA channel 100/10L with surface-mounted, screwed-on slotted grating or longitudinal V2A bar grating has been part of our portfolio for over 35 years.
The particular feature of this GRP channel is its surface-mounted and screwed-in-place grating. Since the grating covers the entire channel body, it perfectly protects the channel edges from damage.
The WOLFA slot drain made of GRP is the most elegant solution when sophisticated architectural requirements need to be met. The slotted top is 100 mm high and replaces the broad drainage channel cover. With its opening width of merely 10 mm and optional colors from charcoal to light gray, the slot drain perfectly fits the looks and design of any environment.
Areas of application: linear drainage of facades, entrance areas, stairways, driveways, public places and other sealed surfaces
The WOLFA 100V-Line drainage channel suits many applications. The great variety of gratings makes the 100V-Line a universal channel system.
The WOLFA 150V-Line drainage channel with a clear width of 160 mm is ideally suited for professional sectors and for the absorption of large amounts of water.
Areas of application: linear drainage of facades, entrance areas, stairways, public places and other sealed surfaces
The flat WOLFA channel convinces with its nominal width of 164 mm and installation height of only 98 mm. Thanks to the many different load class A15 - C250 gratings, the 150F channel can also be used for commercial applications.
Areas of application: Underground ramps, driveways, walkways and pedestrian areas
The WOLFA 150K professional drainage channel features a clear width of 164 mm and an installation height of 150 mm. Thanks to the wide range of grating options in load classes A 15 to D 400, the 150K drainage channel is ideally suited for professional commercial applications.
Areas of application: Commercial and industrial areas, loading bays, yards, parking areas and areas with heavy traffic.
The large WOLFA PROFI channel for the intake of large quantities of water. The channel with an inner width of 210 mm is ideally suited for the intake of large amounts of water. The optimized flow cross section and smooth, pore-free surface accelerate the water discharge and self-clean extremely effectively.
The new large PROFI drainage channel for collecting large volumes of water.
The WOLFA 200F flat drainage channel features a clear width of 210 mm and an installation height of only 98 mm. Thanks to the wide range of grating options in load classes A 15 to D 400, the 200F drainage channel is ideally suited for professional commercial applications.
With a linear drainage system, the surface is generally sloped evenly towards the drainage channel. In contrast, surfaces with point drainage usually require a two-way slope or a concave shape. A linear drainage system consists of several channel sections connected in a continuous run to form one complete drainage line.
For our GRP drainage channels without bolted gratings, the grating can simply be lifted out of the installed channel for cleaning. If your drainage channel is fitted with a bolted grating, simply loosen the fixing screws to remove the grating and clean the channel. Occasional removal of leaves and coarse dirt is generally sufficient.
Our GRP drainage channels do not necessarily have to be installed with a gradient. A so-called water level gradient is sufficient, meaning that the water rises inside the channel towards the outlet before draining away. If the channel is installed with a gradient, the drainage capacity increases and the channel remains cleaner because dirt is carried away with the flowing water. Unlike concrete channels, there is no risk of frost damage, spalling or cracking.
WOLFA GRP linear drainage systems are ideal for collecting and draining rainwater from driveways, commercial premises, parking areas and other paved surfaces.
Our low-profile drainage channels are particularly suitable where only a limited installation height is available. For projects with high architectural requirements and a discreet appearance, our GRP slot drain is the ideal solution. WOLFA also offers suitable drainage systems for many other applications.
GRP offers several advantages over conventional materials:
Yes. WOLFA GRP drainage channels are suitable for vehicle traffic. Depending on the selected channel body, grating and installation method, different load classes up to Class D 400 (40-ton wheel load) can be achieved.
