ERTEC E-Fence™ is fantastic! Compared to another I’ve used, it’s much easier to work with and install, and very effective for the species on my projects. – Jennifer McCarter, Terrestrial & Wetland Biologist, Natural Resource Solutions, Waterloo, Ontario
Newest Case Study: Ministry of Transportation, Ontario. HWY 401 Project: Species at risk: Eastern foxsnake, Common snapping turtle
“Excluding wildlife from construction sites can be challenging, particularly for Eastern foxsnake. E-Fence offers an effective and efficient solution to multi-species projects that have varied exclusionary requirements. This product is durable and adaptable to site conditions which allow for customized field-fit solutions.” - Martine Esraelian, Terrestrial Biologist, Parsons Inc.
“The Ontario Ministry of Transportation selected the E-Fence Rigid Polymer Matrix product to provide an effective measure for reptile exclusion from the construction work zone while ensuring no hazards to vehicles within the highway right of way and minimal maintenance required for the exclusion fence.” Heather Mitchell - Senior Environmental Planner - Ontario Ministry of Transportation - West

Wildlife Exclusion Fence – Special-Status Species Protection
Description – ERTEC E-Fence™ Wildlife Exclusion Fence
ERTEC is by far the world leader in special-status small vertebrate exclusion and directional barriers
(E-Fence™ Brochure). ERTEC has the experience that only comes with manufacturing and installing millions of feet and hundreds of projects. ERTEC engineers have learned from feedback from hundreds of biologists to guide its continuous improvement and innovation process and to expand its effective configurations and accessories for a broad array of species and conditions. E-Fence is patented, durable and the lowest cost Wildlife Exclusion Fence or directional control barrier designed for projects in habitat where special-status small vertebrates are present. The fence is designed to exclude small vertebrates from active construction areas, control movement within fragmented habitat and for control of survey-area perimeters. The barrier is made from a heavy rigid polymer matrix which is extruded for strength and durability. The extruded strands of the ERTEC matrix will not separate, stretch or entrap even persistent intruders. Unlike metal mesh, it does not present a laceration hazard and unlike mono-filament plastic mesh (found in erosion control products) it will neither entangle nor entrap. It will not corrode and decay like metal hardware cloths or geotextile fabrics. Unlike silt fence, plywood fence, or other solid polymer barriers, E-Fence allows high wind and heavy stormwater flow-through. It can be installed across contours (up and down hills) without enduring the destructive and scouring effects of storm water runoff. It is non-toxic and environmentally safe. Even after extensive exposure to sunlight, harsh weather and salt water it continues to perform. E-Fence provides very high reliability (up-time) which significantly reduces maintenance and monitoring costs. E-Fence can be used for temporary or permanent requirements. It is a ZERO Waste solution (reusable and recyclable). Accepted by wildlife agencies, E-Fence is configurable for individual or combinations of species and flexible for special conditions.
