Going Green > Structural Soil

Structural Soil is a designed growing medium which meets pavement design and installation requirements while remaining root penetrable and supportive of tree growth.

The major impediment to establishing trees in paved urban areas is the lack of an adequate volume of soil for tree root growth. This often stops roots from growing, causing them to be contained within a very small useable volume of soil without adequate water, nutrients or oxygen. Subsequently, urban trees with most of their roots under pavement grow poorly and die prematurely. Those trees that do survive within such designs often cause displacement of pavement.

Structural soil has been developed and tested so that it can be compacted to meet engineering requirements for overlying paved surfaces, yet reduce the potential for sidewalk damage as well as provide for healthier, long-lived trees.

• Subgrade Capacity Similar to Compacted Stone
  
  
• Promotes Air, Water & Root Growth
  Voids between Solite particles provide necessary space for air, water and root growth
  
  
• High Cation Exchange Capacity (CEC)
  
  
• Contains Voids for Additional Surface Area for Roots
  
  
• Water & Nutrient Retention
  
  
• High Water Release Curve
  
  
• Lightweight & Easy to Mix
  
  
• Air-entrained Soils Encourage Deeper Root Systems
  Supports various pavement types while allowing voids for air exchange, water movement, organic matter and root growth
  
  
• Reduces Stormwater Runoff with its Infiltration Rate
  
  
• Permanent Application Solution
  Reduces the need for pavement repairs due to tree root heaving
