Envirolok Offices
Our History


Envirolok is a family-owned company, built on the principals of small business, and manufactures all components in North America.



Over the last 20 years, we have continued to perfect and lead these standards through proactive testing and collaboration with our clients and engineering industry partners. We have a strong connection to our collaborators, including our sister company, Agrecol Native Plant Nursery.


Envirolok started as a manufacturer of geobag systems, utilizing the industry standard. We continue to work with experts in soils and horticulture to ensure vegetative success without compromising strength and durability.


Our Team

Sales Manager

Eric Seidl is the head of the Envirolok Team. His extensive background in landscape architecture, horticulture, outreach, and engineering has brought Envirolok to a new level of excellence. Eric’s personable and friendly demeanor makes it easy for him to build client relationships and provide excellent customer service. Eric is active in the green industry, volunteering his time to assist with industry outreach, presentations and providing technical review for a variety of events and conferences.

Prior to joining Envirolok, Mr. Seidl spent 20 years in the field of Landscape Architecture, where he focused on waterfronts, parks and open space, and community focused planning.  In addition to design, Eric has a passion for collaboration and building a sense of community.  His most recent work has also focused on design and implementation of sustainable solutions for stormwater management, edible landscapes and effective reuse of invasive hardwoods to create nature-based play and education opportunities for kids.


In his free time, he loves Rockabilly music, camping and spending time in the outdoors with his family and dogs – Daisy and Juniper.  In winter you will find him with his family at the hockey rink cheering on his son and daughter.
