Brock Performance Base™ Drainage

When it rains, it drains.

Brock drains water fast, which allows the athletes to get more playing and practice time on the field in bad weather.  

The key is our patented process of taking polypropylene beads, expanding them, and then melding them together to make an extremely durable yet permeable material that offers both drainage and impact deflection all in one.

Key drainage features

• Brock fields are built on a .5% slope with a slight crown, allowing water to drain both laterally as well as vertically through our material and into perimeter trench drains located on each side of the field. There is no longer a need for stone bases of 6-8” or more in depth to act as a reservoir for excessive water. Sub-Base and Sub-Grade guidelines are available.

• Unlike stone, Brock is a predictable drainage layer that will not change over time.
• Brock eliminates the need for in-field drainage systems (better known as herringbone drains) which is both a material and labor cost savings.
• We tested a field under monsoon-type conditions and passed with flying colors.

Concerned Brock drains water too fast? Don’t be. Our engineering team has conduct-ed extensive studies on Storm Water Management and have had a professional firm design cross sections on how to handle the water flow from a 100-year storm in various parts of the country.

We’ve installed more than 8,000,000 square feet of product, and in some of the most challenging & wettest climates in the world. From Vancouver to Seattle, Ireland to Great Britain and beyond, Brock fields have never had a drainage failure.

Merrick Drainage Report

Brock sent its material to an independent laboratory to test its drainage capability undersynthetic turf. This particular study focused on a typical 10-year storm event for Dallas, TX and Portland, OR. In the Dallas test, a short yet intense rainfall was simulated while in Portland a longer event with steady rainfall was simulated.

The goal was to see how Brock Performance Base and synthetic turf managed these various conditions. The study found that a majority of the water runoff occurs as overland flow and that the lateral drainage capabilities of the Brock material reduces excessive and prolonged ponding of water better than those of a traditional stone base.

Material Permeability Test

This independent test focuses on the permeability of the Brock material itself. The results showed that the rate of permeability of Brock exceeds that measured on many artificial turf fields. Therefore, the materials combined will satisfy national and international requirements for water permeability.
