Green Roof Root Barrier Material
The gr52 can withstand 0 352 gallons per square foot or 1 4 gallons per panel.
Green roof root barrier material. To assist in excess water drainage rubber or plastic modeled drainage elements are often included in this layer. Ram rb 20 root barrier is a 20 mil polymeric sheet ram rb 30 root barrier is a 30 mil polymeric sheet ram rb products effectively arrests root penetration redirect roots to a horizontal growth plane helping lock in vegetation increasing resistance to wind up lift forces. Green roof solutions gr32 and gr52 drainage panels come in 24 x 24 interlocking squares constructed of 100 recycled high density polypropylene hdpp. Green roof solutions root barrier tape is specially designed to seal layers of polyethylene based grs root barrier together.
Root barrier for intensive green roofs made of flexible polyolefin fpo polyester scrim reinforced resistant to bitumen flexible at low temperatures root resistance tested according to the german fll method of 2002 hot air weldable uv stabilized cold applied. In my research i ve found that root barriers installed on green roofs are most frequently made of plastics and that polyethylene and high density polyethylene are the most commonly used materials. Hdpe makes up 47 of the material in all plastic milk water and juice bottles in the u s. Pm10 5 pm18 pm30.
They can also be used to increase the size of the root growth zone and provide space for an aeration system. In conjunction with vegetated green roof planters. They can also provide additional functions for the green roof other than just drainage. Delta root barrier is a special 15 mil 380 µm stabilized polyethylene design to be strong tear resistant and root resistant.
Root barriers are often used in green roofs to provide some protection to the waterproofing from invasive stolons rhizomes and from woody roots from trees and shrubs. All green roofs need a layer of material that is root resistant. Green roofs can also reduce stormwater runoff. These may not be required if the waterproof membrane is certified as root resistant.
Its superior strength is designed to protect the waterproofing membrane from aggressive plant roots. Manufactured from 100 polypropylene the membrane is designed to prevent root penetration. A root barrier can be incorporated into the waterproofing itself or may consist of an additional membrane on top of the waterproofing. The green roof root barrier membrane protects your primary waterproofing layer and structure from roots when installing a green roof.
The grs gr52 panel size is 24 x 24 x 2 125. It will not absorb water and is non toxic perfect for even the most sensitive green roof plant life.
