Dust Control
Here at Kortech, we don’t believe safety should come at a price. Our dust control solutions increase safety of driving on dirt roads by improving visibility and reducing fine dust particles, all for one low cost. Dust control also helps improve overall health, by elimination fine dust particles in the air that can cause respiratory illness.
Products Required
- W 1.32 calcium chloride (CaCl2)
- MG-30 calcium Chloride/magnesium hydroxide
Benefits of Dust Control from Kortech
- Increases visibility on dirt roads by reducing the number of fine dust particles that are dislodged
- Largely reduces the number of fine dust particles that get blown into adjacent homes and create respiratory complications
- Lessen the amount of fine dust particles that get blown into adjacent environmental areas, such as bodies of water
- Conveniently balances easy application and effective results with low cost
- Proven to reduce gravel loss by up to 40%, which reduces your re-graveling costs and overall maintenance costs
- Treated road surfaces can still be bladed without substantial product loss
- Results in a hardened road surface and stronger base to reduce road surface problems and maintenance costs
- Reduces frost heaving caused by the freeze-thaw cycle and lessens spring and fall maintenance costs
- Product is not palatable to wildlife and helps keep wildlife away from treated road surfaces
- Calcium chloride is naturally occurring right here in Central Alberta, lowering the cost of our calcium chloride brine for customers across Western Canada
Environmental Impact
Here at Kortech, we care about protecting the environment and reducing our environmental impact. All our products are kept at a safe concentration level that is gentle on the environment. In fact, calcium chloride is non-toxic and can be found in fertilizers in low concentrations.
Studies conducted by the Department of Highways in Ontario have concluded that calcium chloride is non-hazardous and does not require placarding during transportation. These same tests determined that calcium chloride is the least aggressive agent among dust palliatives.
How to Calculate Quantity Required
To achieve the most effective range of application and enjoy the most benefits of dust control, we recommend a quantity between 1.5 litres and 2 litres per square inch, at a depth of 2 inches. This can easily be calculated in 2 simple steps.
Step 1: Find the surface area of your roadway in m2 (length x width)
| Length of Roadway (m) | Width of Roadway (m) | ||
| – | 5m | 7m | 10m |
| 100m (0.1km) | 500m2 | 700m2 | 1,000m2 |
| 200m (0.2km) | 1,000m2 | 1,400m2 | 2,000m2 |
| 500m (0.5km) | 2,500m2 | 3,500m2 | 5,000m2 |
| 1,000m (1.0km) | 5,000m2 | 7,000m2 | 10,000m2 |
Step 2: Calculate the amount of product needed (area x application rate)
| Application Rate (litres per m2) | Area of Road Surface (m2) | ||
| 500m2 | 2,500m2 | 10,000m2 | |
| 1.5 litres/m2 | 750 litres | 3,750 litres | 15,000 litres |
| 1.7 litres/m2 | 850 litres | 4,250 litres | 17,000 litres |
| 2.0 litres/m2 | 1,000 litres | 5,000 litres | 20,000 litres |
Base Stabilization
Calcium chloride base stabilization is a cost-effective treatment to harden a road surface to reduce rutting from heavy traffic. It also reduces surface erosion and sedimentation, improves safety on the roads by reducing dust, raveling, and wash boarding, and lessens costly frost penetration.
Products Required:
- MG-30 calcium chloride/magnesium hydroxide
Benefits of Base Stabilization from Kortech:
- Hardens the road surface and reduces rutting from heavy traffic
- Binds the particles in the road’s surface to create a higher compaction level (as compared to an untreated surface)
- Contains the added of benefit of a clay component called magnesium hydroxide that is very effective in silty or sandy aggregates
- Reduces the need for regular blading
- Decreases number of potholes, washboard, and soft sports in a road surface
- Product does not harm surfacing of asphalt or pavement
- Lessens frost heaving caused by the freeze-thaw cycle and reduces spring and fall maintenance costs
Environmental Impact
Calcium chloride is non-toxic and does not require placarding during transport, as confirmed by tests performed by the Department of Highways in Ontario. These same tests determined that calcium chloride is the least aggressive agent among dust palliatives.
A Swedish study has found that calcium chloride can reduce frost lenses (which cause troublesome frost heaves) by up to 60%.
How to Calculate Quantity Required
There are additional application costs to consider with base stabilization apart from the cost of calcium chloride. For example, the cost of trucking and application can be included in your purchase of calcium chloride, however, we recommend having a water truck pre-wet the aggregate at a rate of 0.7 – 1.0 litres/m2 before we apply the calcium.

Environmental Impact
A key value at Kortech is protecting the environment. That’s why we use a safe concentration of the non-toxic calcium chloride product to provide ice and sand control services year-round. In fact, the Washington State Department of Transportation determined that calcium chloride has fewer corrosive properties than typical road salt. This makes it easier on road surfaces and reduces road runoff that can have a negative impact on the surrounding environment.
When applied correctly, calcium chloride poses a very low hazard risk for humans and animals. Our concentration levels should not cause irritation to skin or animal paws during brief contact, but it is not recommended to come into direct or prolonged contact with any chemical product.
Studies conducted by the Department of Highways in Ontario have concluded that calcium chloride is non-hazardous and does not require placarding during transportation. These same tests determined that calcium chloride is the least aggressive agent among dust palliatives.

FAQ
Do I need to add additional aggregate to my road’s surface?
New aggregate is not necessary if the surface material can be bladed to a depth of 1.5 – 2 inches. However, gravel is separated overtime through heavy vehicle traffic pounding, environmental factors, and aggregate loss. Fresh aggregate would ensure that the proper mix of rock, clay, and fines are present in the material mix and is recommended for optimal application benefits.
How long does it take to apply a base stabilization?
1 km to 1 mile per day is very achievable giving consideration to the weather and other factors that may cause delays on a job site.
How long will the effects of base stabilization last?
Base Stabilization is a permanent solution for solidifying a roadway as the product is incorporated into the aggregate and has no way to migrate out. Surface maintenance of the top 2 inches may be required on an annual or bi annual basis.
