Treated vs Untreated Soil
Suitable Soils Treated with TERRA-3000 Are Highly Water Resistant
- We source a variety of soil samples from work sites across Australia.
- We mix the soils with water until the samples reach their optimum moisture content suitable for compaction.
- We divide the mix into two batches, and treat one batch with TERRA-3000.
- We then apply equal compaction to both samples creating pucks (small cylindrical samples of compacted soil).
- We allow the pucks to dry naturally at room temperature or in sunlight.
- We mark the treated pucks with the letter ‘T’, indicating it has been treated with TERRA-3000.
- Both treated and untreated pucks are then partially immersed in water. We observe the outside of the pucks for noticeable capillary action above the water line. Minimal capillary action is a positive sign that the soils are suitable for treatment with TERRA-3000 Concentrate. Untreated pucks invariably fail eventually. The failure times are largely dependant upon the pucks soil profile, and it can vary from a couple of minutes to a few hours, but the end result is the same. Despite having being formed with the same compressive strength as the treated pucks, the untreated pucks will succumb to the penetration and capillary action of water.
- A more graphic example of what water can do to untreated soils is by using rounded hand compressed samples called “meteors”. These samples are both fully immersed in water, side by side. Typically the untreated sample will last less than a couple of minutes before completely disintegrating, whereas the treated samples will retain their shape permanently, whether immersed or not. During testing we remove the fully immersed treated samples once per day to measure their weight to ascertain whether they have absorbed water. Typically absorption rates are between 1-2% with no further degradation in results over the duration of the test. Properly treated samples can remain fully immersed and unaffected by the water, which can no longer penetrate the soil.
