Guar | Guar Alternatives | Psyllium | Sandbags | Silt Fencing


Guar is a plant native to India. Primary world suppliers include: India, Pakistan, and the United States, with additional acreages in Australia, Africa, and portions of the Mediterranean.

In India, Guar is grown principally for its green fodder and for the pods that are used for food and feed. It has soil-enriching properties since it is a legume. According to the American Society of Agronomy, the primary importance of guar is the commercial value of its seed gum (galactomannan gum).

Guar and its derivatives are used in a variety of industries. For example, in landscaping and erosion control guar is used as a binder and tackifier in the hydroseeding mix. In addition, guar is the base ingredient in different formulations of erosion control and landscaping products. Guar is used as an emulsifier, stabilizer, and thickener in various food products, and it is widely utilized in paper and textile production, in mining, and in the oil industry.

One erosion control expert wrote: “One advantageous property of guar gum is that it thickens without the application of heat. Below are some of the characteristics of this product that make it useful in a variety of applications:

   • Easy solubility in cold and hot water

   • Film forming property

   • Resistance to oils, greases and solvents

   • Better thickening agent

   • Water binding capacity

   • High viscosity

   • Functioning at low temperatures

Guar Alternatives
HF5000™ is an organic tackifier specially chosen and designed for use as a tackifier in hydraulically applied systems expected to provide long-term strength and erosion control. HF5000™ may be utilized with fiber or as a stand-alone over-spray or dust control.

Psyllium Husk is derived from the seed of the Plantago Ovata (Psyllium) plant and is cultivated in the Northwestern region of India. Used in a number of commercial applications, psyllium seed, husk and powder are all-natural, time-tested ingredients used in dietary supplements designed to treat a range of digestive system disorders. Like guar, psyllium seed and husk are also used in hydroseed slurries and in erosion control products.

Sandbags & Silt Fencing
Northstar Impex offers a range of sandbag and silt fencing options for industry professionals working in construction, landscaping, emergency response, and erosion control.

Silt fencing provides a temporary barrier that retains sediment. The fence is composed of geotextile with supporting posts that are dug in the ground. By slowing the flow of runoff and creating deposition on the uphill side, the fence retains sediment and also filters runoff as water passes through. The result is less pooling of sediment and water in a highly soluble area.

Silt fences have a much better success rate than straw or hay bales, and also prevent sheet erosion by decreasing the rate of runoff. Silt fencing is an easy-to-install and cost-effective way to control sediment and prevent soil erosion.

Spectac is an organic tackifier manufactured in the USA and is specifically designed for use as a hydraulically applied erosion control tackifier. SPECTAC is used as a stand alone temporary erosion control product or with wood, paper, or other native fiber mulches to provide superior bonding strength.

SPECTAC is specifically designed to develop optimal slurry viscosity to improve sprayability and pump performance. SPECTAC disperses in water creating a lump free slurry, saving time and money.




History: Guar, or clusterbean, (Cyamopsis tetragonoloba (L.) Taub) is a drought-tolerant annual legume that was introduced into the United States from India in 1903. Commercial production of guar in the United States began in the early 1950s and has been concentrated in northern Texas and southwestern Oklahoma.

History: Psyllium has a long history of use throughout the world. Psyllium has been used in traditional medicine in India and finds mention in ancient Indian Ayurvedic prescriptions.
