Stud substrates

Presentation :
This substratum is used to create roughness on a water way to facilitate the passage of fish species. The studs are 30 mm high with a minimum spacing between studs of 14 mm. It is possible to define either an aligned or staggered alignment of the studs. The shape of the studs reduces clogging and facilitates cleaning; the material used offers a good impact resistance.

Installation :
The substrate covers a ramp with double dip:
– Lateral dip: from 5 to 20 ° (maximum). Width of equipment will be adapted to the upstream water level fluctuation. The portion of the gutter used by fish is covered with less of 20 mm of water deep.
– Longitudinal dip: from 5 to 30 ° (Maximum). Length of equipment is adapted to the difference level, above 2.5 m high, it is necessary to create a resting pool.
