Deep Drill

Deep Profile Restoration

Over time, the performance of a sand-based putting green can change far below the surface. Iron can move downward through the rootzone and precipitate at the sand-gravel interface, forming what is commonly referred to as an iron-cemented layer or iron sediment layer — a hard, iron-oxide deposit that can restrict the movement of water and air through the profile. Fine particles and organic material can also migrate downward and accumulate at this interface. As these layers develop, a green designed for rapid drainage and healthy gas exchange can gradually lose its ability to function as originally intended.

Traditional aeration and even deep-tine cultivation generally address the upper portion of the profile. If the restriction exists near the gravel interface, treating the upper several inches doesn't address the underlying problem.

Specialized Deep Drill equipment penetrates up to 18 inches, passing through the rootzone and into the gravel layer. The drilling action disrupts accumulated material, fractures and churns the layer, and creates vertical pathways through the entire constructed profile.

By restoring pathways through restrictive subsurface layers and into the gravel drainage system, Deep Profile Restoration can help a compromised sand-based green function more closely to the way it was originally designed — improving vertical water movement, gas exchange and overall profile performance.

Quotes from customers:

"Wow, I have roots like ropes!"

"They are definitely faster and firmer"

"I struggle much less with the ‘problem greens’ since the service" 

"My older sand-based greens perform like they're brand new"

For courses experiencing declining performance in older sand-based greens, Deep Profile Restoration provides a way to address problems that may exist far below the reach of conventional cultivation. Many of our clients incorporate the service into their ongoing management programs after seeing the improvement in their most problematic greens.

After cleanup and rolling, Deep Profile Restoration surfaces are immediately playable.
