EU requirements make it necessary to install underwater windows in fish passes.
They are used to monitor fish population levels. These are large-format, thick windows, from 50 to 70 mm. With our construction chemicals, we can install acrylic directly onto reinforced concrete. The condition is careful grinding and maintaining proper planes. The reinforced concrete also cannot contain voids or pockets filled with loose material.
This set of underwater windows was particularly difficult to install because the panels had to be transported by barge. From there, the panel was lifted and placed at the installation site by crane.
