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.

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:

Pre-Construction Checklist

Golf Design Unlimited, LLC Page 5

1. Heavy-duty vehicle to haul mix from the ready-mix truck to the bunker. Examples: Toro 1 Workman, John Deere ProGator, Tractor and dump trailer, articulating wheel loader, front dumper, etc.

2. Plywood or similar to protect turfgrass and bunker edge and for building a ramp into the bunker if desired. Timbers, logs, etc. can also been used to create ramps.

3. A minimum of eight pieces of 4” (100 mm) to 6” (150 mm) diameter irrigation or drainage pipe cut into 2 inch (50 mm) lengths. Use these rings to maintain the 2 inch (50 mm) required mini- mum depth of the Capillary Concrete during placement. Remove the rings from the wet mix as you work out of the bunker. Attach a handle or make a wire loop on each piece of pipe to avoid losing them in the mix. A metal probe set at 2 inches (50 mm) is also acceptable.

4. Construction of the Vault – a 2” x 2” wood frame, at least 4 ft long and as wide as the trench must be

Golf Design Unlimited, LLC Page 6 made and placed in the lowest spot of the bunker floor, on top of the trench. The frame and all gravel must then be removed to just above the drainage pipe before the sand is installed in bunker. Should The

Capillary Wash Box be installed, all gravel must be removed around the pipe to be able to fit the Capillary

Wash Box directly on the drainage pipe. The Vault must then be filled with bunker sand to create as deep of a sand layer as possible in this low point of the bunker.

5. Flat shovels for placement of Capillary Concrete inside the bunker.

6. A minimum of three plastic bunker rakes-the Accuform type bunker rake with a round head is preferred. The teeth can be used to move the mix around to the required 2-inch (50 mm) depth, and the rounded back side, and the rounded back side can be used to smooth the mix before rolling.

7. A minimum of two one piece metal extension handles with with metal tips. Telescoping handles 7 are preferred as they allow for longer reach. Metal handles and tips. Home Depot has anorange metal 5 ft.

handle with a metal tip in the paint department. SKU#821-423.

Golf Design Unlimited, LLC Page 7

8. A minimum of two heavy duty 9-inch (23 cm) roller frames. Home Depot has a green Wooster

Surelock handle that works well. SKU#150-345.

9. A minimum of two 9 inch (23 cm) loop textured roller cartridges, if the textured roller can ́t be 9 found, use a regular paint roller with the fabric removed or cover a roller with duct tape. Home Depot used to call them Goop Loop Rollers. SKU#430-546.

10. At least One 12 to 14-inch pool trowel. (30-35 cm) Some installers prefer using a larger trowel for finishing the floors as well. Do not use a bull float. Home Depot Part# PT144BR

Golf Design Unlimited, LLC Page 8

11. Purchase adequate plastic to completely cover all the Capillary Concrete bunkers completed in a day.

The plastic can be re-used for the entire project. Home Depot SKU#938-963

12. 6-inch (15 cm) metal staples to hold the plastic down after placement. Staples should be 12 placed every 3 feet (0,9 m) round the perimeter of the bunker. Sandbags, bricks, logs, old tires (etc.) are also acceptable. The idea is to hold the plastic in place during curing.

13. Two 5 gallon (19 liter) buckets of water to keep rollers wet.

14. A hose and quick-coupler with a misting nozzle and working shut off valve for misting of the product during installation.

15. Optional: For easier placement of material. 15 Marshalltown 19-1/2 in. x 4 in. Aluminum Placer

Home Depot SKU #959687 Model #AP753

Installation Instructions

Temperature Limits

Capillary Concrete should not be installed when daily high temperatures are expected to be below 32 degrees (F) or below 28 degrees (F) within 2 days of installation. During hot weather, windy, or low humidity conditions, the product will set up faster and caution must be exer- cised to maintain acceptable

Golf Design Unlimited, LLC Page 10 moisture levels of the mixture and bunker base prior to installation. A light misting of the bunker subfloor may be required several times during the installation process.

1. When the ready-mix truck arrives at the job site, you will need to ensure the correct consistency of the

Capillary Concrete before installation can begin. Before discharging any mix, ask the driver to spin the truck 5 revolutions to adequately mix the product. (It’s been mixing since it left the plant, but we find this to be a good way to ensure mix uniformity)Now it’s time to perform a HAND SQUEEZE TEST as shown here. Ask the driver to discharge a small amount of the Capillary Concrete mixture into the utility vehicle you are using to haul the mix to the bunker. It should be shiny and look like melted chocolate and rock.

Take a handful of the mix and squeeze it in your hand and release. The paste must be creamy and sticky enough for the aggregate particles to adhere to the vertical surface of your hand. If the paste is dry and powdery, the mix is a little too dry and you need to ask the driver to add water to the mixer truck. Never add more than 1 gallon of water at a time (unless otherwise instructed by an onsite Capillary Concrete representative), check after, ask the driver to turn the drum a minimum of 15 revolutions before checking the mix again. Continue this process until the mix has the feel of melted chocolate. Be careful not to add too much water. It’s always better to add a little at a time.

We cannot take the water out once it has been put in the mixer. The paste should NEVER be drippy and runny when you perform the hand squeeze test. The mix should always have the consistency of melted chocolate. Continue to monitor the consistency as you install - YOU MUST perform the hand squeeze test occasionally to ensure consistency during the installation. An additional gallon of water may be required after a few loads have been installed. If so-ask the driver to add one gallon and rotate the drum

15 times before discharging more mix. If the mix is extremely wet and runny when the ready-mix truck arrives, ask the driver to spin the drum for 5 minutes to try to dry the mix up a bit. If that doesn’t work and the discharged pile for testing has clogged up void space, you should refuse the truck, send it back to the plant, and contact your Capillary Concrete Representative immediately. DO NOT install Capillary

Concrete if the mixture is too wet.
