concrete trench drains

Like standard concrete, simply better.

BG-FILCOTEN® HPC (High Performance Concrete) is a 100% mineral material — an enhanced form of conventional concrete engineered without styrenes, synthetic fibres, or polymers. Its optimised high-density structure makes it possible to build drainage channels that are lighter, stronger, and cleaner than anything conventional concrete or polymer concrete can offer.

The result is a channel body that bonds with the surrounding concrete bed as a single continuous unit, reacts to temperature changes identically, and carries no harmful substances from installation through to end-of-life recycling.

How to order

Three parts. One system.

Every trench drain assembly combines a channel body, a grating and a set of accessories. Here's how the pieces come together.

Part of the assembly

The grating isn't an accessory - it's engineered into the channel.

Every BG-FILCOTEN® channel body is designed around a matched grating: the rail profile, lock recess, and surround concrete depth are all sized to the grating's material and load class. Drop the wrong grate on the wrong channel and you lose the rating.

Function first, form follows - every BG-FILCOTEN® grating trades off load capacity, corrosion resistance, and appearance differently. Pick the material, then the load class.

Engineering

Built for the long run.

Every detail of the tec V is engineered to outperform - from the snap-on grating system to the textured exterior that bonds permanently with surrounding concrete.

fiX Snap-On Anchoring

The integral four-point quick-release, spring-loaded fiX system holds gratings firmly in place while allowing tool-free removal for maintenance. Two anti-sliding lugs prevent any longitudinal shift.

Superior Self-Cleaning

The ultra-smooth flat inner surface (36 µm roughness) minimizes friction and achieves best-in-class flow characteristics - outperforming polymer concrete at 36 µm+ and conventional concrete by a wide margin.

Permanent Bond to Substrate

Computer-designed anchoring ribs increase exterior surface area dramatically, giving far better adhesion to the surrounding concrete bed. The identical linear expansion coefficient ensures a permanent fit with no seasonal movement stress.

High Compressive Strength

Patented fiber-enriched HPC formula delivers exceptional compressive strength in thin-walled construction - no synthetic resins required. FILCOTEN® outperforms polymer concrete and glass fiber modified concrete on all key metrics.

Galvanized Steel Rail

Integral 2 mm galvanized steel rail on the tec V provides secure grating lock-in with adjacent surface attachment points. Engineered fixing lugs distribute load evenly across the FILCOTEN® channel body.

Temperature & UV Resistant

Cement-bonded fiber composite reacts to temperature change identically to the surrounding concrete bed, creating a unified, stress-free system. Resistant to frost down to −40°C/−40°F, de-icing salts, and UV radiation throughout its service life.
