GRO Metal Edging adds a great finished look to all Green Roof Systems, or to rooftop pavers and tiles. Strong, yet lightweight, it can accommodate design curves and angles in rooftop projects.
CONCRETE CURB EDGING
Designed for durability and function, GRO Concrete Curb Edging is an attractive edging that defines and separates spaces on green roofs and amenity decks.
BULK ENGINEERED SOIL
We offer engineered green roof soil media designed for multilayer green roof systems. Available in lightweight extensive and heavier intensive blends, GRO Engineered Green Roof Soil is tested to ASTM standards. Available for delivery in bulk and super sacks.
GRO DRAIN COVERS & LIDS
GRO Drain Covers and Lids provide effective drainage and protection from debris entering the roof drains for rooftop decks and green roofs. Designed to be lightweight for rooftop applications, they provide a functional purpose with a polished look.
A lightweight and efficient stormwater retention product, with very high water retention capacity. For use below vegetation and soil layers, GRO Mineral Wool is an engineered horticultural approach to stormwater management. Maximum water retention with minimum weight.
A thick geotextile mat made from mechanically consolidated, needle punched, polyester fibers. For use in horizontal and sloped green roof applications for additional water retention.
GRO DRAIN MAT – 0.5”
GRO Drainage Mat 0.5” is a ½” thick drainage core made from an extruded polymer matrix of tangled monofilaments, which are thermally bonded to a non-woven geotextile. It provides excellent filtering performance, high tensile and tear strength, and is a functional and economic choice for use in typical layered systems.
GRO DRAIN MAT PLUS – 0.5”
GRO Drain Mat Plus 0.5” is similar to our GRO Drain Mat – 0.5” but has an additional layer of spun-bond fabric on the bottom. This double-sided fabric drain mat can eliminate the need for an extra protection sheet for the roof’s waterproofing system.
GRO LOW FLOW DRAIN MAT – 0.25”
GRO Drainage Mat 0.25” is a 1/4” thick drainage core with an extruded polymer matrix of tangled monofilaments, thermally bonded to non-woven geotextile. With high tensile and tear strength, this drain mat provides additional stormwater detention time and slows the rate of stormwater flow to roof drains.
GRO HIGH RETENTION DRAIN MAT – 1.0”
GRO High Retention Drain Mat is a 1.0” thick high-retention drainage panel made from HDPP. For use with green roof systems when maximizing water retention capacity is a priority. GRO Filter Fabric must accompany this product.
GRO HIGH COMPRESSION DRAIN MAT – 0.5”
GRO High Compression Drain Mat 0.5” is a geocomposite drainage mat consisting of a polyethylene core, covered with a non-woven geotextile filter fabric on top, and a protection fabric on the bottom. The core of this drain mat provides high compression and stormwater retention, while the permeable filter fabric prevents engineered soil from entering and blocking the core. This is for use under heavy loads, like pavers/pedestals or concrete curbing.
GRO FILTER FABRIC
GRO Filter Fabric is a highly permeable, non-woven, needle punched geotextile separator for green roof systems. A permeable solution to prevent engineered soil from blocking drainage in a GRO Layered System or as an optional protection layer between a GRO Modular System and the roof’s waterproofing membrane.
GRO ROOT BARRIER 30
GRO Root Barrier 30 is a smooth HDPE 30 millimeter geomembrane film for use when required by municipalities or project specifications. As a waterproof seal, it protects the soil from moisture loss and also redirects the roots of larger plant material.
GRO ROOT BARRIER 20
GRO Root Barrier 20 is a smooth HDPE 20 mil geomembrane film for use when required by project specifications or municipalities. It aids in protecting the waterproofing membrane from root intrusion from more aggressive/larger plants.
