Overview

Safeshell® is our nontoxic, organic infill option that doesn’t compromise on safety, integrity, or quality. Made of 100% USA-grown walnut shells, it’s low-maintenance, long-lasting, and remarkably safe for people, pets, and the environment—a total game-changer for your turf system.

Lowest Maintenance

Unlike other organic infills, Safeshell stays in place, doesn't break down, and doesn't change in the hot or wet climates. The round shape of each grain helps the product resist compaction. It doesn’t float and plays the same wet or dry.

Naturally Durable

As the most durable natural infill on the market, Safeshell won’t break down and it doesn't float, which means there is limited migration of the product and it stays in place. With the 8-year warranty and limited top-off required, you'll be able to always depend on Safeshell for athletic fields, yards, playgrounds, and more.

Cooler Temperatures

Safeshell excels at evaporative cooling - the key to a cooler playing surface. It absorbs water with minimal expansion and then releases it slowly over time to help keep surfaces from heating up too quickly.

Safe & Organic

With Safeshell, you get peace of mind that your infill is made from organic and food-grade components. We also developed a patent-pending process that reduces allergens that remain on the shell after separation from the nut. Following FDA guidelines, our process removes allergens below 2.4 parts per million.

Grown in the U.S.A.

Safeshell is made of 100% USA grown walnut shells. When buying Safeshell, you're supporting American farmers and agriculture.

Proprietary Blend

To achieve optimal performance, we blend Black and English walnut shells to make Safeshell. Black walnut shells are thicker; once the shells are ground, the grains are rounder and less abrasive. Combining them with the thinner, less round grains of ground English shells results in a proprietary mix that’s the perfect balance of firm, fast, and player-friendly.

USDA Biopreferred

Safeshell contains 100% USDA certified biobased content showing our company meets the high standards set forth by the USDA Secretary of Agriculture.

Perfect for Landscape

Safeshell is a versatile natural infill that can be installed in athletic fields as well as landscape applications. Use cases in residential and commercial applications include lawns, playgrounds, recreation, and play spaces. For smaller landscape applications, such as a backyard, front yard, or commercial lawn, Safeshell is sold in 25lb bags and can be shipped anywhere in The United States.
