Using our Engineered Soil Technology (E.S.T.),
we manufacture blends that meet strict specifications.


"We'll work with what you've got."

Natural Sand Company specializes in the production of top-quality engineered soil products for the athletic field and golf course industries. Using our Engineered Soil Technology (E.S.T.), we manufacture blends that meet strict specifications. Most importantly, we’ve engineered our growing line of mixes to meet the meticulous needs of our customers.

We provide soil solutions to clients at every level of play - from community parks to professional stadiums. We’re ready to assist you with your athletic field and golf course construction, renovation and maintenance needs.

Engineered Soil Technology outperforms other methods because it is based on Soil Science, Not Guesswork. Grant’s E.S.T. Program assesses the current state of the infield, then prescribes specific corrective measures to transform a poor infield into one with the highest performance possible.

DuraEdge Mixes have superior performance results
due to our ability to:

  • Control soil ratios in the blending process, which
    enables customization of mixes

  • Replicate DuraEdge Mixes at multiple locations
    throughout the country

  • Reproduce the same mix from Year to Year –
    Consistency in material

In order to properly balance your base soil, the first step is to understand who you are. To determine who you are, you need to answer two questions:

1. Do you have access to water?

2. What are your facility maintenance resources/practices?



Classifying your facility is important because what works for the big leagues will not necessarily work for everyone. Who you are determines where your soil levels should be, and what you should do to balance your base soil.

Despite what other companies may say, it IS possible to improve your current infield material without removing and replacing it. Infield amendments save time and money and are just one of our specialties. Our engineered soils are your solutions. Each product we manufacture undergoes rigorous product testing. This process ensures consistent products and predictable outcomes for you, the valued client.


The SCR is a score derived by dividing the percentage of silt by the percentage of clay in a soil sample. The SCR score indicates the relative performance of an infield soil product.

Imbalanced based soils on ball fields often have either:

High sand content and low SCR
- Typically a field that is “beachy” when
   dry or “chunking out” when wet.

Low sand content and high SCR
- Typically a field that is “dusty” when
   dry, or “mucky” when wet.

Once you know the composition of your base soil, you can implement the proper solution with the assistance of a trained DuraEdge sales representative. The DuraEdge sales representative can explain the Engineered Soil Technology (E.S.T.) process and we computer blend materials that enable us to select the combination of amendments required to balance your existing base soil.

TACS Method

Most infield soils are simply mined from the ground and screened off at a certain size and sold. In other words, it is what it is. But for Natural Sand Company’s infield soils, screening is just the beginning. After harvesting the raw materials for our infield soil products, we mechanically blend the sand and clay together at specific ratios.

  • Blend of 72% Sand; 12% Silt; 16% Clay

  • Lower Silt to Clay Ratio enables a firm playing surface

  • Low maintenance – does not require access to water to maintain field

  • Higher clay to silt ratio allows for firmer playing surface

  • Compatible with various amendments such as conditioners and psyllium powder for customized solutions

  • Lower maintenance – does not require access to water to maintain material
