1. Prepare the Soil
Use tillers and disks to pulverize the soil to a depth of six inches of greater, preparing for the DuroEarth process.

|
|
2. Apply enzyme solution
A water trailer or a truck outfitted with an adjustable spray bar will distribute the soil hardening enzyme solution.
|
|
3. Mix the soil
Once saturated, the enzyme is mixed thoroughly into the soil using a tiller of the TR3. Turning the soil over with a moter grader blade also provides excellent mixing.
|
|
4. Create windrows
The enzyme-treated soil is then bladed to the side in windrows, exposing a solid road base. The treated soil is left to cure in the windrows for 24-48 hours. This process begins to dry and harden the soil.
|
|
5. Crown the road base
The road base is crowned or sloped, and then compacted while the enzyme soil cures over a 24-48 hour period.
6. Apply ROAD-HARD
ROAD-HARD is applied in its dry state by a drop spreader to the compacted road base. It is mixed into the ground with the tiller to a 2-inch depth.
|
|
7. Apply ROAD-HARD additive
The ROAD-HARD Additive (not the enzyme) is then mixed and sprayed onto the ROAD-HARD covered base. This is then scarified, compacted, and left to dry. This prevents the capillary rise of water.
|
|
8. Replace windrowed soil
After 24 hours the curing enzyme treated soil is replaced over the waterproofed layer and compacted.
|
|
9. Final application of ROAD-HARD
The roadway and shoulders are treated with ROAD-HARD again (repeat step 6). This waterproofing solution encases the enzyme hardened soil in a water-resistant envelope.

After DuroEarth application.
The DuroEarth process is a comprehensive method for building durable, water resistant roadways, runways, hardstands and berms. The patented process uses eco-friendly polymers and enzymes to harden soil and create a water-resistant "slab" of earth that is functional year round and resists erosion and supports traffic. This hardened slab is encased in a hydrophobic envelope of soil that prevents both the surface penetration and the capillary rise of water.
