EarthZyme is a non-toxic soil stabilizer used on

clay-based soils that results in a reduction in road

maintenance costs due to increased and lasting

compaction and strength values.

Application Rate: EarthZyme

Road Length = 1000 m (1 km) Road Width = 40 m Depth = 0.50 m (50 cm) Volume Soil = 20,000 m3 (compacted) Amount of EarthZyme (EarthZyme is applied on average 1 liter / 33 m3 of compacted soil) = 20,000 m3 divided by 33 m3 = 629 liters of EarthZyme *An optional slurry application of EarthZyme may be recommended, see step 7

8

Application Rate: (Optimal Moisture)

Say the current moisture content is 7 %,

The optimum moisture content is 11 % and the soil has a density of 2.2 tons/m3

Required moisture to be added: = (11 % - 7 %) x 2.2 x 20,000 m3 (compacted

soil)

= 1,760,000 liters of water

At 2% below OMC

= 800,000 liters of water

Before EarthZyme After EarthZyme

EarthZyme is 100% biodegradable and works on the clay-based fraction of the soil.

After EarthZyme’s application, the clay particles in the soil are no longer attracted

to water, allowing for any water present in the soil to drain away freely resulting

in the clay/soil particles settling closer together and producing lasting soil stabilization.

10

EarthZyme reacts permanently with clay in the soil to produce long-term stabilization.

Other products glue the clay particles together.

Once the glue is gone... so are the results of the stabilization process.

Because EarthZyme uses the

clay as the natural binder, which

remains in the soil indefinitely, it

produces the long term effects

that are desired.
