Protect your landscaping and hardscapes from the severe damage water can cause.

Water Barriers
WB, 24, WB 36, WB 48
Made of extremely tough yet light-weight polyethylene DeepRoot ® Water Barriers manage subterranean water movement and are ideal for preventing water damage to hardscapes and planting areas such as:
  • curbing and sidewalks 
  • roads 
  • foundations 
  • driveways 
  • traffic islands 
  • cart and bike paths 
The smooth plastic can be formed into any shape or size. Strategically positioned or sealed to hardscapes these barriers can be used to corral or redirect subterranean water movement and surface run-off. Each water barrier is .030" thick and comes in a 300' roll. Available in 24, 36 and 48 inch heights. DeepRoot sealant tape is included with Water Barrier.

WB 24, WB 36, WB 48 Uses:
  • Prevent snow, ice and saltwater run-off from polluting planting areas adjacent to roadways and parking areas. 
  • Controls run-off, preventing hardscape damage. 
  • Prevents irrigation water from percolating under pavement. 
  • Water corral for planting areas that prevents pavement damage and saves water.
