TERRASIL is a liquid product that is supplied in different types of containers, the most used being the 20-liter container.
TERRASIL dissolves in water (with the recommendation that the water has a maximum solid residue of 1000 ppm) forming a transparent solution with a viscosity identical to that of water itself, so it can be watered or dosed by spraying with any equipment that can pump water or even by gravity (irrigation tanks, personal application equipment, hoses, soil stabilization equipment, etc…)
There are several ways to apply the product according to the benefit you want to obtain.
Wet stabilization
To improve the structural capabilities of the soil, according to the parameters mentioned above, the product TERRASIL is applied like any other wet stabilization, adding Terrasil to the water used for compaction.
The process can be done with a specific stabilization equipment or with a motor grader.
Afterwards, the mixing and compaction is done.
Dosage
- Calculate the content of Terrasil to provide to the soil (kg/m3): Ct (Terrasil content per m3).
This parameter is usually 0.3kg/m3 to 2 kg/m3.
Example: Ct= 0.4kg/m3. - Calculate the water to be contributed at each moment to the soil (difference between the optimum moisture content for compaction (OMC) and the moisture content in -situ).
HA= Moisture content (per m3).
Example: Optimum moisture =14%.
Moisture in-situ = 8%.
Moisture to be supplied =6% (HA%).
Density = 2000 g/cm3 =d.
Ha= HA% * d = 120 liters. - Calculate the dissolution rate of Terrasil in the compaction water:
Ratio = Ha/Ct = 120/0.4 = 300.
That is, 1 liter of Terrasil is added in the tank for every 300 liters of water.
This ratio is usually between 1:50 and 1:600.
Example of construction process on existing soil
Scarification of existing soil by 15 cm.
Addition of dry stabilizers (lime or cement).
Filling of the irrigation tank with water and contribution of the stabilizer in the calculated dosage.
Watering of the solution of Water and Terrasil on the material.
Mixing of the material to be stabilized.
Levelling and profiling, pumping and natural gutters.
Compaction until reaching the density of the project.
Waterproofing irrigation
This technique consists of applying a solution of 1 part of TERRASIL in 300 parts of water and watering until a compacted soil is saturated.
When evaporation curing occurs, the treated soil will behave as a waterproof (but breathable) membrane that will prevent water permeability either by gravity or by capillarity, becoming an excellent protection of the infrastructure.
This solution can also be applied on asphalt roads whose aging causes cracks and damage to the base layer due to humidity.
