Infinitely Better Roads
Considerably lower costs
EarthZyme is a unique multi-enzyme product specifically developed as an effective aid to the workability,mixibility, binding and compaction of soil.
EarthZyme significantly improves stability in construction of roads, dams, landing strips and many other related projects.
EarthZyme is a totally natural bio-degradable product. By its actions it alters and improves a soils physical and chemical properties which result, in significantly less mechanical effort to achieve greater densities for compaction.
EarthZyme offers a convenient and low cost method for improving a soils strength and durability, enabling lower construction costs, less maintenance and greater road performance.
EarthZyme has cationic actions which bind dust particles together to maintain a longer dust free environment. Suspends in water needing no agitation and is easily applied with standard water spraying equipment to any application.
"You must be the change you wish to see in the world."
-Mohandes Karamchand Gandhi (1869-1948)
EarthZyme creates a base that is strong and very hard. This is a diamond tipped concrete saw that had to be used to extract a small piece of the shoulder of this now very solid durable road base.
1. UNSEALED ROADS AND SHOULDER TREATMENT
EarthZyme when used on unsealed roads creates a stronger, dense pavement, utilising higher clay contents and PI than would normally be suitable. Trials over the past four years show, that by incorporating EarthZyme during the water binding process, unsealed road maintenance has significantly been reduced, less dusting occurs and gravels may last two years longer before re-sheeting. These overall improvements save money and safety on unsealed roads. Many users have received favourable reports from their ratepayers.
2. SUB-GRADE
The effects of EarthZyme are greatest on natural clay insitu material. When applied to natural sub-grades, increases in CBR of 30% to 40% have been achieved. Increases of 4% to 5% density for the same compactive efforts and reductions in both O.M.C. and PI can occur. These improvements in soil strength can lead to a significant reduction of imported base gravels and costly transport.
3. BASE COURSE
Where base-course material is not of high quality and has too high a PI (clay content), EarthZyme may be used to increase the soils physical characteristics to a suitable seal standard. Significant savings have been achieved by improving base materials.
4. LIME AND CEMENT STABILISATION
When used with lime or cement EarthZyme improves the effects of these additives sufficiently to reduce their quantities by 50%. The effects of lime and cement with EarthZyme mean the application rate may also be reduced by 50%.
BENEFITS OF THIS COMBINATION ARE:
a) Cost reduction in additives.
b) EarthZyme keeps density high.
c) EarthZyme assists workability. In some cases the rotary hoes are not required.
d) Contains sugars which retard EarthZyme /cement setting time, allowing compaction to meet density specifications.
APPLICATION
Rate of application is worked on the volume of soil to be treated. The volume of water required to reach optimum moisture content is not a part of this formula.
Standard formula for EarthZyme quantity is as follows: One litre (0.26 gallons) of EarthZyme will treat 35.5m3 (46 yd3) of compacted soil.
FORMULA
Length of pavement x width of pavement x depth of treatment - divide by application Rate = litres of EarthZyme required.
L W D
eg. 1000m (3300 ft) x 7m (23 ft) x 0.100m (0.33 ft) divided by 35.5 (4725) App Rate = 20 litres (5.3 gallons).

TO APPLY
We need first to have pavement ripped to desired depth of treatment.
We then want to get additive into soil as early as possible. Product is applied with the water truck. If you would normally need an estimated four passes of the water truck to bring material up to optimum then we would put additive in the first two passes for the day. From then on use water only.The trick is to get even distribution of additive over the area to be treated.
The next stage is mixing. This can be done as simply as blade mixing or rotary hoe or other similar type machinery.
It is suggested that you fill the water truck before adding EarthZyme This will prevent frothing due to surfactant component of the mix.
It is also necessary to watch optimum moisture content carefully to prevent from going over wet. The additive will improve wetability, workability and penetration thus enabling us to reach optimum earlier.
EarthZyme has been designed so as to fit in with normal existing construction procedures. The product has 7 day setting time so it is possible to put product in the soil a day before putting the pavement down without fear of it setting or going off.
