TerraZyme soil stabilizer offers consultants a unique solution to today’s road construction problems. If your goal is client satisfaction, TerraZyme soil stabilizer delivers the best possible road quality and improves your ability to stay within your client’s budget constraints.

​

Increase in CBR% and Flexural strength

​

TerraZyme improves the load bearing capacity of soil. Roads constructed using TerraZyme design concepts often reach a CBR (California Bearing Ratio) value of 90% or more in the base or sub-base layer as compared to 50% or less for an untreated structure. This improvement in flexural strength ensures a longer economic life for flexible pavements placed on roads built with TerraZyme.

​

Using TerraZyme does not require a significant amount of additional knowledge. TerraZyme works on the principle of cation exchange where a cation with a higher charge (valence) automatically replaces a cation with a lower charge when they come in close proximity to each other. Understanding this process is simple, and there are tools available to measure TerraZyme's successful application. The quality of a road constructed with TerraZyme is generally measured by conducting field DCP (Dynamic Cone Penetrometer) tests. The results are calibrated to CBR percentages to determine the improvement in the flexural strength from the soil stabilization process.

​

Increase control over road quality

​

The construction of road infrastructure is often plagued by the need for compromises. The required layer thickness needed to build a lasting road structure is often not feasible because of budgetary constraints. TerraZyme offers consultants an opportunity to increase the quality of road layers within the required cost of construction by using a higher percentage of available local soils.

​

Increase in construction speed

​

TerraZyme is easy to apply. It is also safe to use on soil and safe for the people who apply it. A crew using standard road construction equipment can easily exceed a stabilization output of 3,000 square meters per day. Applying TerraZyme with a road reclaimer, can create an output of up to 50,000 square meters per day.

​

Nature Plus offers programs to train consultants and construction teams on TerraZyme’s application procedures. Engineers with a general knowledge of soil mechanics, and experienced construction equipment operators generally acquire the experience to successfully work unsupervised with TerraZyme within two days.

​

Decrease in wear and tear of road surface

​

TerraZyme increases the flexural strength of road sub-base layers. Consequently, surface pavements, such as asphalt or concrete, experience less movement from vehicle loading. The result is a significant reduction in a road’s need for maintenance in comparison to standard soil road structures. Moreover, repairs on TerraZyme base layers can be executed quickly, without compromising the quality of the overall road structure. Soil stabilizer usage needs to be written into road project specifications so that project bidding includes this option. TerraZyme stabilization options may be excluded from specification if road officials, design engineers or road consultants are not aware of the technology.
