Conservation Technology is the North American distributor for Optigreen (Optigrün International AG), world leader in the green roof industry.  Optigreen green roof fabrics, drainage systems, and accessories comply with demanding European standards and represent the culmination of thirty years of field experience. Optigreen products have been used to build more than 350,000,000 square feet of green roofs, perhaps one-third of all green roofs worldwide!

Conservation Technology also custom-fabricates greenroof waterproofing systems using state-of-the-art rubber membrane technology.  Both our sheet and our factory seams meet the German FLL standards for root resistance.  By supplying single sheets up to 10,000 square feet, we can eliminate the risks of failures at field-fabricated seams.  We can also custom-fabricate polyethylene root barrier membranes for use with other waterproofing systems that may not be root resistant.

We maintain an extensive stock of protection fabrics, separation fabrics, capillary fabrics, drainage mats, drainage plates, aluminum edging, drain access covers, slope-stabilization systems, soil stabilizers, slow-release fertilizers, and paver systems.  We can supply selected components or complete green roof systems:  the choice is yours.  We also provide design assistance and technical support.
