Installing A Bent Grass Putting Green From Artificial Turf and Putting Greens

 

Installing a Bent Grass Putting Green from Artificial Turf and Putting Greens doesn't require you to have a green thumb. You don't have to be a greens-keeper or have special equipment. Most of the tools required for the installation process you probably already own. And the ones you don't have you can find at a local rental company. So what are you waiting for?

Step 1:
Decide on the Placement of your Green

Check out placements in level areas of your property.

  • Take a string, garden hose, or extension cord and lay it in the general area and shape you desire. The width of our turf is 12 or 15 feet so you will need to think in widths of 12 or 15 feet when designing your green (12, 24, or 15, 30 feet wide) unless you plan on cutting and seaming the rolls (if this is your intentions please see steps 9-12 first). The turf can later be cut to any length although it is sold in 5 foot increments. By marking the area like this you will be able to actually see the size and shape.

  • Refer to your diagrams in your brochure to help determine a size and shape.

  • Once you see the size and shape make sure to practice your golf game a little. You may decide you need a larger green.

  • Use spray paint to mark the entire outside perimeter of the shape. This marked edge will be used as a reference point where your sub base material will be placed.

Be sure your green is accessible from other areas of the yard by chipping and pitching to the marked area

Step 2:
Remove the Sod

  • Whether you are doing an in-ground or an above ground installation use a sod cutter or shovel to remove the grass in the area you have marked with spray paint.

  • Remove any loose debris after the sod has been taken out.

Step 3:
Prepare the Ground

  • Compact the bare ground using your plate compactor to ensure a solid foundation for the crushed stone base.

  • Lay out the weed barrier on top of the ground in the area where the green will be installed. The weed barrier acts as a stabilization cloth and does not allow the crush stone sub base material to sink into the ground.

Step 4:
Add a Border

Leave enough room on the inside for your basic material plus a half inch or less for the putting green surface...

Add an edging as a border along the entire outside perimeter of the area where your stone base material will go. This will ensure the base material will stay in the marked area and will not be pushed out beyond your area when compacting the base. If you are using a block border or retaining wall then the weight of the block will hold the base in place

Step 5:
Add the Base Material

 

The base is just that, It is the foundation of your new golf tool... The more time that is spent perfecting the surface of your base material, the better the surface of your green will be. One of the tricks that we use in the field is taking a bright colored tennis ball, and rolling across the surface - watching it carefully. If it bounces cross the surface you'll see that that area is not smooth enough. It is also recommended that you take the string long enough to go from one end to the other. Stretch it tight so you can see if you have high spots or low spots that need your attention. Repeat this in several different angles across your base area.
The basic material should be crushed rock that will compact. Depending on the area of the country you're located in, there will be different materials available (3/8 minus crusher fines, # 8 crushed limestone, 3/8 road base , or crushed granet).
You can also do your basement material in two layers. The first layer is a road base material that consists of gravel stone approximately 3.5" or less. The second and top layer consists of stone dust, #7 limestone dust, crusher fines or rock dust, as it is commonly referred to.
1.5 to 1.9 tons / 100 Sq. Ft. (roughly 3in. in depth)
Make sure to distribute the sub base material evenly. Work with a yard rake spread out the sub base material so that it is consistently flat.
Use a shovel to move the large amounts of sub base material and the flat side of a rack to smooth out any rough areas of the sub base.
Drainage will come off the top of the green, not through the green. Drainage through the green would eventually deteriorate the packed sub base. There must be a slight slope to the sub base for proper water drainage. A good rule of thumb is a 1 inch drop for every 10 to 12 feet in length.

Step 6:
Compact the Sub Base

It's a good idea to keep spraying water to dampen the surface while you are tamping...

If you do not compact the sub base material properly it will eventually settle in a way that will cause irregularities in the surface of your putting green. These irregularities adversely affect the roll of your ball when putting. Remember that the plate compactor can be rented from any local rental facility.

  • With your garden hose’s spray nozzle wet the sub base lightly. Do NOT saturate it.

  • Now compact the sub base. To ensure good solid compaction, make sure to compact the sub base several times the length and width of the area.

If there are any small bumps, ridges, or irregular dips remaining smooth them out with your rack or shovel. Use a 2 x 4 to screed or level the base material. You may notice low spots or dips on your base. Chances are that you have a low spot on the sub base that needs to be filled.

Your main goal is to keep the surface consistently flat, smooth and solid.

  • Adding undulations or contours is easy.

  • Add additional base material to that area.

  • Shape it with your rake until you have the desired contour and undulation.

  • Compact that area with your plate compactor. Understand a 1 inch rise over 10 to 12 feet will add a lot of contour once the putting green is added.

The putting green turf is designed to fit like a glove to the surface. If you add too much slope to your sub base material the ball will roll very fast and may roll off your green.

A good basic guideline is for every 10 to 12 ft in the length of your sub base you will drop the slope 1 to 4 inch

To determine whether you have enough or too much slope or contour-- after the sub base material is completely compacted take a golf ball and putt on the sub base.

The ball will break the same on the sub base as it will when you install the putting green. Your sub base should be a minimum depth of 4 inches when compaction is complete.

Make sure the sub base is the way you want it. If you want to add or take away extra slopes or contours now is the time to do it. However, if you make any changes to the sub base then you must re-compact the sub base after the changes are made. Once the putting green and the infill is added it is difficult to adjust the contours of the sub base.

Step 7:

Install the Cups

  • Arrange the cups on the sub base.

  • Mark the place where the cup will be permanently placed. This can be done by applying pressure to each cup and rotating it and will cause a small indentation in the sub base that will be used as a marker or reference point.

Using a small hand shovel dig a hole that is at least 4 inch larger around than the cup itself.

Because your cups are 6 inches tall you need to make your hole 6 inches + in depth. The cups once placed in the holes should be one quarter inch above the top of the sub base material. Don’t worry if you go deeper because you can always back fill the hole with the base.

Plumb, Level & Concrete

 

1/4'' above base.

                too low                                  too high

 

  • Add ready mix concrete around the cup & about halfway up the outside of the cup.

  • Next, add sub-base around the exposed perimeter of the cup.

  • Compact the sub-base around each cup by hand tamping or running the compactor around the cup keeping the cup  1/4" above the base.

  • Continue to do each hole in the same manner.

Step 8:
Finish the Base

You might notice small ridges caused from the plate compactor, on your finalized compacted base. These ridges must be removed. The putting green turf will fit like glove to your base so you want the base to be as smooth as possible.

  • Use the bottom of a shovel or hand tamp to flatten the ridges.

  • Use the drop spreader to distribute the commercial grade medium sand over the entire base. A 50 pound bag of sand will cover a 15 x 30 area. JUST TO FILL IN LITTLE INPERFECTIONS...

  • Use a medium bristle push broom to lightly sweep the sand and any loose gravel off your base. This will fill in any cracks and crevasses and give you a super smooth base.

If using the standard 15 ft. wide measurement for your green then you may omit steps 9-12.

Step 9:
Join rolls together (part1)

Call tech support for any help needed...

 

 

The seaming techniques create an invisible seam. You will be provided with black seaming tape strips and commercial strength outdoor adhesive. A 1/8 in. notched trowel is needed to spread the adhesive.

The fibers of the putting green turf are slanted or have a slight grain running the length of the roll.

Make sure the grain of each roll of putting green turf is running in the same direction.

  • Place the green on the edge of the sub base and roll it out.

  • Make certain there are no creases in the turf or it will affect the roll of the ball. If there are very small creases or bubbles don’t worry. When you infill the putting green the small creases and bubbles will go away with the weight of the infill.

  • ? Separate the fibers. Before spreading the infill it is necessary to separate the fibers of the putting green the best you can. This can be done by pushing your broom against the grain of the putting green. Also, brushing against the grain will help to stretch out any small creases or bubbles. You will always be brushing against the grain during the infill spreading process.

  • Brush the fibers against the grain several times in order to get the fibers vertical and to separate the fibers before infilling

  • Notice the black strip running the length of each roll.

  • Lay one roll over where the seam will come together so the black backing is facing up.

  • Take a utility knife with a brand new blade and cut between the first and second row of stitching the length of the roll.

  • Cut as close to the second row of stitching as possible without cutting into it. Take your time and do not cut into the stitching. Do this for only one of the rolls where your seam will be joined. Cutting between the rows of stitching will provide you with a guide-line and will remove the black strip. This will give you tight fit and a perfect seam when you join the rolls together.

Step 10:
Cut the rolls

  • Place your piece of tin flashing under the bottom roll that is being overlapped. The flashing will make for a solid and smooth cutting surface and cutting the seam will not disturb your smooth sub base.

  • Overlap the rolls about 2 inches the entire length at the seam so that the roll with the black strip still attached is on top.

  • Place bags of infill every 5 feet on both sides the length of the seam. The weight of the infill will not allow the rolls to move during the seaming process.

  • Starting at one end of the roll, cut the top overlapped roll of turf by following the edge of the bottom roll with your utility knife.

  • Continue this process the full length of the seam. This technique will make for a perfect cut and seam.

  • After the seam has been cut, join the two pieces together to ensure a tight fit before gluing the rolls together in step 12.

REMEMBER: Continue to replace your utility knife blade after cutting eight to ten feet in length. The goal is to cut through the turf and not rip through it.

Step 11:
Add Seaming Tape and Adhesive

 

HINT: There should an equal amount of black strip on each side of the seam.

  • Spread the adhesive over the entire surface of the black strip. Make sure the thickness of the adhesive is no more than 1/8 inch.

  • Allow 20 to 25 minutes for the adhesive to set up and get sticky before seaming.

  • Lay each piece of the putting green turf over at the seam.

 Step 12:
Join rolls together (part2)

  • Starting at one end of one roll, lay one roll onto the adhesive and seaming tape the full length of the seam.

  • Lay the second roll over as you join the two rolls together.

  • Press the seam in place as you go applying pressure to ensure good contact of the turf backing and the adhesive.

  • Once the entire seam has been placed together walk several times over the area that has been seamed.

  • Allow 30 minutes before starting the infill process.

Step 13
Shape your Green

 

DO NOT CUT OUT CUPS UNTIL YOU ARE DONE!!!

 

If you have no edging to run your putting green up against or if you're going to add friends. Using a piece of chalk draw your shape, then stand back and look at it prior to cutting.

Note: This carpet cutter is not the best tool - use a sharp utility knife and cut form the back. (Click Here To See More Info on this method.)

The green is delivered in a rectangular shape. You may desire to shape the green to give it a natural look. Refer to your brochure for shapes.

If you are not adding a fringe turf to your putting green, cut the shape of your putting green using your outside border as a guide. If you desire a fringe around your putting green, use a yard stick to assist you with measurements.

FOR EXAMPLE-
On one installation we used a two foot collar of fringe turf around the putting green.

REMEMBER: The fringe turf is functional-- you can chip off of it.

Formula to determine the amount of fringe turf needed for a two foot collar of fringe:

Total length + width Divide by 2.5 

Example:

On a 30 X 26 putting green the length is 52 feet if you place the two 15 by 26 rolls end to end.
52 + the width of 15 = 67
67 divided by 2.5 is about 27

A 15 X 27 foot roll of fringe turf is needed to give a 2 ft collar of fringe around the putting green.

  • Use your yard-stick to measure two feet in from the border.

  • Use a string to mark your shape in 1 foot increments.

Use a utility knife (with new blades) to cut along the outside perimeter of the string. This gives you the desired shape.

Step 14:
Add the Fringe Turf

Cut the fringe material from the back - when possible cut between two rows of stitching...

To maximize your fringe and minimize waste-

Run the fringe turf the length of the putting green on each side first, then the two widths.

HINT: The grain of the fringe turf must run the same direction all around the green.

  • Roll out the fringe turf over one side the length of the shaped putting green.

  • Overlap the entire roll of fringe turf just enough to cover the shape of your putting green on one side the length of your putting green.

  •  

  • NOTE: Do this step after infilling green STEP 15 :

  • Nail down the fringe into the sub base using 4 inch galvanized nails with small heads 2 inches out into the fringe from where the seam of the putting green turf and fringe turf will meet.

  • Place the nails every six inches the entire length of your fringe turf.

HINT: Nailing between the rows of stitching will hide the nails

  • Next, come out 1 foot into the fringe turf.

  • Nail down the fringe turf 1 inch out into the fringe every six inches the entire length of the fringe. Nailing the fringe at both the seam and a foot out from the seam will anchor and secure the fringe turf in place and make for a very tight fit.

  • Continue to do this for the entire perimeter of fringe turf.

  • Cut along the outside perimeter where the fringe meets your border.

HINT: Replace the blade on your utility knife every 8 to 10 feet of turf you cut to avoid dulling a blade and producing a ragged cut. Try to avoid “ripping” the turf.

Step 15:

Infill the Green

Infilling putting green

DO NOT CUT OUT CUPS UNTIL YOU ARE DONE SANDING!  

CUTTING CUP HOLES IS THE LAST THING YOU DO! see bolow

 

INFILL MATERIAL: "Surger Sand" Fine, Dry “clean” (no dust) sand 30/60 grit, some call it fine or “000”. Sand blasting sand works well and can be found in most locations. Also look for pool filter sand, but it has to be dry so it will go through the drop spreader.

 

QUIKRETE® Commercial grade sand Fine No.1961    

#30 - #70 grit (0.6-0.2 mm)

 

3/4" DBL Eagle   3.5 to 4 LBS. per sq. ft.

    (350 LBS to 400 LBS per 100 sq.ft.)

 

1/2" Eagle   1.5 LBS. to 2 LBS per sq. ft.

 

 

Some sandblasting suppliers have black diamond and you can use it as a top dressing. 2 lbs. silica and the last .5 to 1 lb. black diamond.

 

NOTE: You can also run the plate tamper across the green to help vibrate the sand in...

 

 

HINT: The putting green and infill MUST stay dry during this filling process.

If the infill or putting green gets wet the infill clumps together, not allowing the infill to get between the fibers of the putting green and be properly filled.

  • Fill the drop spreader 1/2 full with the infill.

  • Spread it across the top of the green.

HINT: The weight of the infill will flatten any small bubbles you may have on your green. Do not apply too much infill at any one time without first brushing the infill into the fibers.

For example, a good basic guideline is to use 100 pounds of infill over an entire 15 X 30 green between brushings.

 

REMEMBER: Always brush from the center out to take out all air pockets out from under green.

  • You must brush between all infill spreading.

  • Once the green is half full, brush the putting green using consistent force.

  • This infill procedure must be repeated until you have filled the green completely full, close to the top.

HINT: You can't overfill the BentGrass green. This applies for all 3 turf lengths..

  • Over-filling of the green ensures a consistent level of infill across the entire putting green surface.

Step 16:
Infill the Fringe

By infilling the fringe turf the fibers will stick straight up or vertical. You only need to fill the fringe turf half full to achieve this.

  • Use your broom to consistently brush against the grain of the fringe. This gets the fibers to stand up.

Step 17:
Sweeping the Infill off the Green

broom

  • Always brush from the center out to take out all air pockets out from under green.

    • You must brush between all infill spreading.

    Brush the excess off the putting green.

  • Sweep the green a second time to remove any excess infill. Your goal is to have 3/32 to 1/4 inch of the putting green fiber exposed.

HINT: If the green appears blotchy in color note that the first rain will wash the infill dust off the fibers and settle the infill into the green.

Step 18:
Cut the Holes for Your Cups.

  • Locate the cup holes by pressing the turf with your hands until you feel the holes.

Using a utility knife (with a brand new blade) cut the holes out of the turf.

  • First, cut an X inside the hole.

  • Cut tightly around the inside edge of the cup marked by the X.

 It is very important to take your time with cutting around the inner edge of the cups.

Take a screwdriver and run it around the outside of the cup, pushing the turf around the outside of the cup (Like putting a bicycle tire on a bicycle rim). This will insure a tight fit.

 

  •  After the holes are cut, trim the loose fibers around the cup with hand scissors.

 Step 19:
Roll the Turf - (Optional)

 Rolling of the green will determine the speed of you putting surface.

  •  Using a water filled roller, roll the green the length & width of the entire surface.

  • It will take several times both the length and the width of the putting green to achieve the speed you desire. Once you have done this you will not have to do it again in the future.

NOTE: This is a great tool to tuck the putting green or the fringe in around your edging. (between the edging in the crushed rock base material)
