The Bunker Edge

To maintain the nature of the product, every effort should be made to prevent soil contamination of

Capillary Concrete during installation, curing, and prior to sand installation. Two methods to safeguard your installation from contamination:

1. Grassing around the perimeter of the bunker prior to Capillary Concrete installation: With this method, it is recommended that turf grass around the perimeter of the bunker should be secured to the soil by roots or staples before the installation of Capillary Concrete. After installation and curing and a water test has been performed to ensure drainage function, sand can be installed in the bunker. For newly sodded bunkers, where additional irrigation is required for rooting and establishment, we recommend that a thicker layer of sand (approx. 8-10 inches high x 10 inches wide) be installed on inside perimeter of the bunker against new sod. This is done to allow the sand to act as a filter layer to catch any soil runoff during irrigation cycles on the newly placed sod. Once the sod is established and irrigation cycles are reduced, any contaminated sand around the perimeter should be removed. Bunker sand can be leveled and normal bunker maintenance practices can begin.

2. Capillary Concrete installation prior to sod placement: In situations where grass cannot be installed prior to the installation of Capillary Concrete, extreme care must be used to prevent soil contamination.

Sand should be installed immediately after curing and the water test. As in method 1), a thicker perimeter layer of sand should be installed to reduce soil contamination prior to sod placement. After establishment, any contaminated sand around the perimeter can be removed.

Golf Design Unlimited, LLC Page 50

Planning and Construction of The Bunker Edge The edge detail often gives the bunker shape its distinctive style. Capillary Concrete has the unique ability to be formed to fit any Architects design goals.

Preserving the desired style or motif and reducing ongoing maintenance is critical to the success of any bunker restoration/renovation plan.

1. Existing bunker and sod renovation The strength of Capillary Concrete allows the opportunity to protect the inside wall of the bunker better than any other product. Cap- illary Concrete has the ability to be shaped almost vertically at installation to get the least possible amount of soil in contact with the bunker sand. In this photo the subgrade under the existing turf has been excavated 3-4 inches and a layer of Capillary Concrete has been placed under the sod to help protect the edge from collapse and contamination. Sand is pulled up the face to hide the Capillary Concrete edge.

2. New sod layer around the perimeter In this case, either the existing soil and grass, or sod is utilized as the edge of the bunker. The 2-inch (50mm) layer of Capillary Concrete meets the edge of the bunker.

Rolling the sod over the face to cover the soil is an option.

Bunker Sand Testing

Capillary Concrete has an open structure that allows water to freely drain through it at more than 100 inches per hour. Once sand is placed on top of the product, the new water drainage limit will be the Ksat

(saturated hydraulic conductivity) of the sand that covers the Capillary Concrete product. After gravitational water has freely drained from the sand, a certain amount of water will always be retained in the sand against the force of gravity. This is known as capillary water and the amount can be determined with a Soil Moisture Release Test by an accredited test lab. Every different bunker sand has its own unique amount of capillary water retention based on the amount of moisture present in the sand. If the

Capillary Wash Box is installed, the sand can be modified and finer particles in the sand at the base of the bunker can be removed. Never use a sand that is not an approved USGA sand. For more information on selecting the perfect bunker sand we recommend this information from the USGA:
