EarthZyme® is a long-term solution for stabilizing roads that require continual maintenance due to wet weather and marginal road materials. EarthZyme® targets soils with high clay content by increasing density and providing enhanced stability. Additional benefits include reduced swell and permeability, and increased CBR (California Bearing Ratio) values. EarthZyme®-treated roads perform much better in wet conditions and require much less long-term maintenance. Because EarthZyme® can be used with marginal road materials such as clay, which are less expensive than typical road-base aggregates, roads built with EarthZyme® can be built at significantly less cost than typical road stabilization or re-sheeting projects.

  • Unique multi-enzyme product: developed to aid the workability, mixability, binding and compaction of clay based materials
  • All natural and bio-degradable in 28 days
  • Cost-Effective method for improving material strength and durability
  • Easy Application through standard water spraying equipment
  • Induces cationic action which binds dust particles together to help reduce road dust emissions

The use of EarthZyme road stabilizer will allow for the use of marginal soil materials, thereby reducing the standard reliance on expensive aggregates and gravels. Once applied correctly, the EarthZyme soil stabilization product will result in a road material with lower permeability due to increased density, which in turn results in a harder, more durable road in both dry and wet weather.

EarthZyme is bio-degradable and derives its efficacy on the clay-based fraction of the soil. After applying EarthZyme, the clay particles present in the soil are no longer attracted to water, allowing for any water in the soil to drain away freely. This results in the clay/soil particles settling closer together and producing lasting soil stabilization. Unlike typical road stabilization products, EarthZyme uses the clay in the soil as a binder – not the product itself. Other soil stabilization products glue the soil together; once that glue is gone, so are the results. Since EarthZyme uses the clay in the soil as a binder, it provides for lasting soil stabilization.

EarthZyme is produced in a highly-concentrated liquid form and is applied using standard equipment and techniques. Once applied, EarthZyme will reduce the tendency for a road to exhibit a number of common maintenance problems such as wash-boarding, rutting, heaving, potholing and dust. The product is super-concentrated, therefore making the product cost-negligible per kilometre or mile of road treated, as compared to alternative products or standard maintenance costs of un-stabilized roads. EarthZyme is used primarily to stabilize the base or running surface of an unsealed road, but can also be used as a soil stabilizer under pavement of any kind, and for stabilization of subgrades, etc.

EarthZyme® is super concentrated, so the product cost is negligible—per kilometre or mile of road treated—compared to alternative products or to standard maintenance costs of unstabilized roads.

EarthZyme® is used primarily to stabilize the base or running surface of an unsealed road but can also be used to stabilize soil under pavement of any kind and to stabilize sub-grades.

A soil analysis must be carried out prior to application to ensure the material will be well suited for soil stabilization using EarthZyme®. Soil analysis results may be sent to us for our recommendations and feedback. Performing a soil analysis before you apply any soil stabilization product will reduce your operational road management costs.

Three Soil Tests to Perform Before Using EarthZyme® Soil Stabilizer

  • Particle size analysis, including hydrometer results
  • Atterberg limits test
  • Proctor test

Even distribution of EarthZyme® over the area to be treated is essential for proper soil stabilization and consistency. The pavement on your existing roadbed first needs to be ripped to the desired depth of treatment. EarthZyme® soil stabilizer should then be applied into the soil as soon as possible, pre-diluted with water, with enough water to bring the soil to OMC (Optimum Moisture Content).

EarthZyme® is applied with a standard water truck. If you would normally need an estimated four passes of the water truck to bring material up to OMC, mix the product in with the first two passes for the day. From then on, water is only required during the mixing process.

The mixing process may be as simple as blade mixing with a grader or other simple machinery. For best results, we recommend using a road reclaimer, but in most cases customers will use a grader because it costs less and is easier to find.

We recommend filling the truck with water before adding EarthZyme® soil stabilizer. This will prevent frothing that results from the surfactant component of the mix. Once your road-bed material is brought to OMC and the product is consistently mixed, the material is ready for compaction. Make sure to pay attention to standard road engineering practices, including attention to shaping and drainage.

Please consult with your local Cypher representative before attempting your first EarthZyme® application to ensure the product will meet your specific dust control requirements.

This section will cover the general outline for the application of all EarthZyme® products, a detailed application protocol can be provided by your Cypher representative.

Considering stabilization of existing roadbed, pavement first needs to be ripped to the desired depth of treatment. EarthZyme® soil stabilizer should then be applied into the soil as early as possible, pre-diluted with water, with enough water to bring the soil to OMC (Optimum Moisture Content). EarthZyme® is applied with a standard water truck. If you would normally need an estimated four passes of the water truck to bring material up to optimum, then the product should be placed in the first two passes for the day. From then on, only water is required during the mixing process. Even distribution of the EarthZyme® product over the area to be treated is essential for proper soil stabilization and consistency.

The next stage in the soil stabilization/EarthZyme® application process is mixing. This can be done as simply as blade mixing with a grader or using other similar machinery. For best results we recommend a road reclaimer, but in most cases all that will be used is a grader, as they are cheaper and easier to find.

It is suggested that water be filled into the truck before adding EarthZyme® soil stabilizer. This will prevent frothing due to surfactant component of the mix. Once the soil has been brought to OMC, and consistently mixed, the material is ready for compaction. It is important to note that even when using EarthZyme®, proper engineering practices should still be followed, such as attention to shaping and drainage.
