This helps to lock in vegetation, preventing root damage to the waterproofing membrane and root intrusion into green roof and planter applications while increasing wind up-lift resistance.

 

Terra-BARRIER™ RB-10 is designed for use in extensive Roofscapes® assemblies, lawn applications, and planters exclusively using herbaceous plants. It is not intended for applications using woody plant varieties.

 

BENEFITS:

  • Direct roots into a horizontal plane away from waterproofing

  • Prevent root damage to the waterproofing membrane

  • Prevent root intrusion into green roof & planter applications

 

USES:

  • Extensive green roofs

  • Lawn applications

  • Commercial planters

 

Description:

All laps should be roughly 5 feet or lapped 2.5 feet with all edges taped using Terra-BARRIER™ Seam Tape. Turn up a mininum of 4 inches above the finish elevation line at perimeters and projections, then temporarily tape to the walls. Repair punctures and any other damages before installing the drainage mat.

Terra-BARRIER™ RB-30 is a 30-mil, high-density polyethylene (HDPE) sheet that effectively arrests root penetration and redirect roots to a horizontal growth plane. This helps to lock in vegetation, preventing root damage to the waterproofing membrane and root intrusion into green roof and planter applications while increasing resistance to wind up-lift forces.

 

BENEFITS:

  • Direct roots into a horizontal plane away from waterproofing

  • Prevent root damage to the waterproofing membrane

  • Prevent root intrusion into green roof & planter applications 

USES:

  • Green roofs

  • Landscaping

  • Commercial planters

  • Retaining walls

 

INSTALLATION:

All laps should be a minimum of 12 inches. Turn up a mininum of 4 inches above the finish elevation line at perimeters and projections, then temporarily tape to the walls. Tape all seams with Terra-BARRIER™ Seam Tape. Repair punctures and any other damages before installing the drainage mat.
