As environmental concerns increase, so does the need to prevent harmful articles from contaminating natural water resources. To this end, the unique draining properties of the Gabi® Block have been applied to a special filtering device that can be incorporated into any headwall. The filter is able to retain plastic bags, cigarette ends and other debris which might otherwise pollute our waterways.

The applications are varied and numerous. Because the filter is a stand-alone unit it can be built into a new wall or retro-fitted into an existing one if necessary.
