Terra Guard- Lignin Blend - Organic

Soil Stabilization - Dust Palliatives

Terra Guard is relatively new product that has tested really well the past couple of years we have used it.  Straight Lignin can get temperamental and this new Lignin blend is significantly more forgiving and seems to do much better in all soil types.  It also holds up better in summer rain storms.  Terra Guard is safe to use around sensitive areas and will last 4 to 6 months based on weather and traffic.

"We Grow It Greener"

Terra T.O.P. is relatively new and is quickly becoming one of the best dust control products on the market for the money.  It is a Lignin/Terra Guard/Rosin blend that pulls water out of the surrounding environment  and is NOT water soluble so it can stand up to rain and actually strengthen. Light shot rate allows you to use much less product so the soil pH is less effected by the tiny amount of Magnesium Chloride in the Terra Guard product.

Magnesium Chloride - Dust Off

If you like Dust Off and Magnesium Chloride products, you will love the Terra M product.  Basically a 60/40 blend of Terra Guard and Mag Chloride (Lignin/Vegatable Proteins/Mag).  Cost effective dust control that will hold up to extreme heat and rain much better than straight Mag Chloride products and still keep the hygroscopic properties that make it such an effective dust suppressant, especially in costal areas. 

Tall Oil Pitch is a non-water soluble, extremely viscous, dark brown sticky substance at ambient temperature. It is non toxic, cannot leach and it is not combustable. It differs from the Lignosulphonates which are produced from the sulphite pulping process and are water soluble dispersants

We have a solution for nearly every situation.

DOPE 30 is a Lignin/asphalt blend product that works mainly as a road surface sealant turning gravel roads into temporary asphalt type roadways (see video at bottom of page)  Very durable and good for soils without too much large aggregate. Dope is milled as Cationic emulsion using specialized emulsifiers. The product is usually diluted  with water to allow better penetration to the surface

Also known as 'Dust Off', usually one of the most cost effective ways to handle dust control in a temporary fashion by capturing and holding moisture that already exists in the air to suppress dust where applied. It does however wash off in the rain and it also changes soil pH and can be corrosive on equipment. 

 Dust Oil Penetration Emulsion (DOPE) 30

Lignin is ideal for sensitive areas such as parking lots and driveways where there is a lot of foot traffic, without the worry of people tracking it inside building on their shoes. Lignin works well in clay based soils, DG or base rock. The key is to have adequate fines to bind the soil together. It does notwork well on sandy soils or soils with a lot of alkali. In case of alkali, you need to introduce a surfactant to the soil prior to application to ensure maximum penetration of the product. It also does not work well on red cinders.
