1. Calculate the volume of TerraZyme needed

Quantity of TerraZyme needed is calculated based on type of soil and its volume. (1 L for ever 25 - 32 cubic meters of soil)

2. Calculate the water required to bring the soil to MCD.

Using  a test plot of ground (1 sq yd X 2" deep), determine how much water it takes to bring loose, tilled soil to its Optimum Moisture Content (OMC).  This is the moisture content that will bring the soil to its Maximum Compaction Density (MCD).  Calculate the amount of water required for your project.   

Note: At 7% to 11% moisture, one can estimate the water required by measuring the area and multiplying it by 1.5 to 2 quarts per square yard for every 2 inches of depth (1.5 to 2.0 liters per square meter) to be treated.

3. Prepare the soil bed

Till the soil to the desired depth (6" or greater) until it is pulverized. Hard surfaces may require disking before the tiller is used. 

4. Mix TerraZyme with water

Mix the TerraZyme into the calculated amount of water (gray water is acceptable) and agitate to ensure a uniform mixture.  For projects requiring multiple tanks of water, calculate the amount of TerraZyme required for the volume of your tank from the estimate made in Step 2.

5. Spray the solution on and into the soil(water+TerraZyme) 

• Use #10 irrigation spray nozzles, or comparable,  on the spray bar
• Apply 25–30 psi (1.7–2.1 bar) with a 2" (5 cm) circulation pump
• Maintain a 3 mile (5 km) per hour speed during the application

6. Cover and allow to rest 24-48 hours

Windrow or cover the treated soil to prevent excessive moisture loss and allow to soil to set for 24 to 48 hours. If covering the area is not possible, add an extra % of water so that it can be compacted at or below OMC the next day.  One can also wet the soil the next day, or when  preparing for the compaction step.

7. Cure, shape, and compact

After 24-48 hours, the soil will have begun to cure, dry, and firm up. Spread the curing soil in the windrows across the roadbed and shape the road with a crown or a slope to allow for proper drainage.  Compact the roadbed thoroughly.  (A 6+ ton vibrating  compactor is recommended.)  The road will be ready for use following compaction and the soil's  will continue to cure for several weeks.

8. Apply ROAD-HARD for a water-resistant wear layer

Top and bottom water resistant layers will help preserve the road from water damage. Mixing ROAD-HARD into the soil's body will add extra cohesion and strength to soils with low clay content. 

See L&Q's patented DuroEarth Process using ROAD-HARD as a road sealant.

9. Area is dry and stable
