INSTALLATION STEPS
INSTALLATION SUMMARY

Contact us at [email protected] to let us know you’re working on a project. Our team will help consult to ensure best success. We work best when we’re included earliest.

Check and evaluate surrounding watershed. Identify any low-lying areas. Identify the need for cross slopes, drains, culverts etc.. Consult with us. Identify the type and frequency of traffic to determine depth of install.

Use our product calculator to help you determine quantity and depth.

Prepare and install proper base using your regions DOT guidelines.

Prior to installing OL blended aggregate, make sure the material is properly blended with ideal moisture content before spreading. Add water to achieve approximately 8-10% total moisture. Test using a snowball test. Be sure not to over-water.

Spread with paving spreader for optimal efficiency and consistency.

Compact with minimum 1 ton static roller

Provide a final light soaking to saturate just the top.
ALLOW TO CURE FOR 72 HOURS
Avoid drip edges (water dripping off edge of side of building etc..)
Only use a rolled edge or a firm edge. Anything that moves is no good!
Avoid low-lying areas that accumulate sitting water
WATER FLOW MANAGEMENT

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.
CROWN TO REMOVE SITTING 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).

INSTALLATION DETAILS
1. BASE PREPARATION
Excavate and prepare the subgrade to the depth required in your specifications (taking into consideration both the depth of compacted base and depth of compacted OLSA).

Once the subgrade has been efficiently compacted, you can introduce the base material to the depth required for your installation.

Base Material: It is recommended to use your region’s DOT-recommended road base material, compacted at the depth determined in your specifications (related to expected traffic type).
2. SNOWBALL TEST
Before spreading the Organic-Lock Stabilized Aggregate (OLSA), it is very important to make sure that the proper moisture level of the material has been achieved. The best way to do this is by performing a snowball test.

3. SPREADING MATERIAL
With properly hydrated OLSA, you can begin the installation process.
Using an Asphalt/Paver installer is the most efficient and effective means of spreading the hydrated Organic-Lock Stabilized Aggregate (OLSA) as it provides a consistent depth of placement. Continually feeding the spreader can result in a seamless installation period that is both technically accurate and cost-effective.
Spread and compact the OLSA material in 3-4 inch lifts.


Hand raking can be used in areas where an Asphalt/Paver installer is not possible. In these situations, it’s important to keep a strong focus on depth consistency across the installation.

Be sure to compensate for the expected depth of compaction when finalizing the end depth.
3. COMPACTION

Compact OLSA with a minimum 1 ton static roller. Make 5-6 passes or continue until visible lines are eliminated.

Be sure to hand compact edges or hard to reach areas prior to compaction. The edges of any pathway will often be prone to the most stress as these are often rainfall collection zones. This is a very strong reason why we recommend non-moveable edges, along with a strong compaction right up to the edge.

4. FINAL WATERING
After compaction is complete, it is recommended to provide a final top-dows soaking with a water spray to ensure that the Organic-lock is activated on the surface and all the way throughout its profile, as some areas may be prone to drying throughout the installation process.

EDGING OPTIONS




INSTALLING AROUND TREES
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
- Install full 3” of Organic-Lock™blended aggregate mix over the structural soil up to the trunk of the tree.
- Start at 3” and taper to 2” or 1.5” to the trunk of the tree.
- 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.
