Southwest Greens is proud to present an exciting innovation in eco-friendly infill for synthetic grass that is safe for pets: K9 Sand. This amazing product not only boasts a completely natural composition, but it is also sustainable and carbon-negative, actively absorbing more carbon from the air than is required for its extraction. Read on to find out more about K9 Sand for San Francisco pet turf!



The carbon-negative property has earned K9 Sand a prestigious negative carbon footprint certification from the International Organization for Standardization (ISO). But that is only the beginning of the benefits of using K9 Sand in your turf installation.

K9 Sand is renowned for its uniformly round, hard grains, carefully picked to enhance performance (see Figure 1). Responsibly harvested from naturally found and sustainable deposits on the ocean shelf, K9 Sand ensures long-term ecological balance. Southwest Greens utilizes eco-friendly extraction practices, harvesting less than a small fraction of the total amount renewed each year. This commitment to eco-consciousness ensures that our 100% organic and green turf infill remains in harmony with nature.

Once you get a bag of Southwest Greens' K9 Sand, you'll appreciate its small and uniform grain size, which makes installation effortless. The uniform and round shape of the grains creates tiny voids between neighboring particles, significantly enhancing water drainage. Moreover, the soft shape of K9 Sand lessens wear and tear on artificial grass fibers over time.

The hardness and dustless nature of K9 Sand guarantee a long-lasting and reliable infill solution. But the advantages do not stop there — K9 Sand also helps to keep the artificial turf cool. Each grain of K9 Sand has tiny pores that trap water. As the surface temperature rises, the water in these tiny pores is released, providing cooling through evaporation and reducing the temperature by approximately 20°F compared to standard turf infills. With its superior bulk density (106 pounds per cubic foot), K9 Sand ensures optimal ballast, preventing wrinkling and maintaining an immaculate appearance.



When it comes to caring for the environment, K9 Sand stands above its competition. It is non-toxic, free from heavy metals and plastics, and embodies an unyielding devotion to the well-being of our planet. Moreover, K9 Sand offers distinctive features that make it the optimal infill solution for San Francisco artificial grass for pets. It effectively minimizes the odor of urine (see Figure 2).

Urine’s smell comes from the volatilization of ammonia. K9 Sand tackles this issue by inhibiting the breakdown of ammonia in urine. Additionally, K9 Sand prevents the growth of bacteria, similar to other turf infills with germ-fighting additives (see Figure 3). These remarkable benefits are realized without the need for any additives or coatings — K9 Sand is simply collected from the ocean, thoroughly cleaned, and transported to your doorstep.
