The Beaver Proof Add On is a patented solution created by Keith Poirier. Through 42 years of oil field experience, Keith has found the beaver to be a common and irritating problem. Having tried every possible solution, he knew there had to be an environmentally friendly one. 

This is when the "Beaver Proof Add On" came to life.

The Beaver Proof Add On is made from a wide variety of different sized culverts.  With ingenuity, it's design is very environmentally friendly. It allows for fish passage, virtually unrestricted water flow, and weather and seasonal changes.

The Beaver Proof Add On can be installed on existing culverts in road systems, railways, dams and anywhere the "beaver" is an issue. 

In excess of 100 Beaver Proof Add Ons have been installed and tested since 1998.  They are operating "literally" maintenance free.

INSTALLATION IS THE KEY!!!

NO STREAM SILTATION AFTER INSTALLATION.
