EDGING OPTIONS

There are 2 options for edging. Fixed edge and Rolled edge. If you are using a fixed edge (i.e. concrete), it is imperative that the edge is not movable to ensure full compaction up to the non-movable edge.

INSTALLING AROUND TREES

installing Around Trees
Tree
It is recommended to use a Structural Soil blend when installing a surface material intended for traffic up to the trunk of the tree. Installing Structural Soil is recommended below the root base and out to the radius of the root ball (even extending up to 12′ for more sensitive trees). Install the Structural Soil in lieu of the base material (at the same depth) and then proceed with the Organic-Lock™blended aggregate mix over the surface of the compacted structural soil. Options (lowest to highest rates of permeability):s
  1. Install full 3” of Organic-Lock™blended aggregate mix over the structural soil up to the trunk of the tree.
  2. Start at 3” and taper to 2” or 1.5” to the trunk of the tree.
  3. Install the full 3″ of Organic-Lock™blended aggregate up to the edge of the root ball of the tree, and proceed with unstabilized, aggregate (i.e. same aggregate as used elsewhere, however, un-blended with Organic-Lock™) up to the trunk of the tree.
Be aware that by not using a proper base material up to the trunk of the tree that this area may not firm up to the same level as the other areas but there also shouldn’t be much traffic right by the base of the tree anyway.

CROWN TO REMOVE WATER

It is inevitable that water will have a presence on your pathway surface (through precipitation etc..). To reduce any accumulating surface stress, you need to shape your OLSA surface to promptly remove sitting water using crowns and/or cross-slopes (sitting water on any pathway surface is not ideal).

WATER FLOW MANAGEMENT

Watershed Topography
Before you begin your installation of the Organic-Lock Stabilizeded Aggregate, It is important to consider surrounding topography and canopy cover to understand where water is accumulating and flowing. Reducing water movement stress on your pathway surface can first be accomplished by understanding where the water stress is accumulating and where it is being introduced. Once a concern is identified, introducing berms and/or drains in your design, can alleviate the stress before it hits your surface.
