Claims
1. A method of stabilizing and lining a golf course bunker
comprising the steps of: a. preparing soil by forming the soil and
surrounding landscape into a desired configuration of the bunker
having a liner, a top edge, a lip, an opening, a floor, sides and
turf surrounding the bunker opening; b. forming a hinge point
around the top edge of the bunker such that there is approximately
a 45 degree angle formed by grading the bunker top edge and the
turf surrounding the bunker opening; c. compacting the soil and its
surface; d. applying a liquid adhesive polymer to the surface of
the soil to assist in stabilizing the soil; e. allowing the soil to
stabilize; f. applying a barrier material around the bunker floor
and sides and continued on up over the top of the bunker while
maintaining an approximately 45 degree angle and for a distance
past the bunker; g. allowing the barrier to harden; h. applying
another layer of liquid adhesive; and optionally applying a layer
of clean, dry bunker sand to the bunker floor and sides; and i.
curing of the bunker liner.
2. The method of claim 1 wherein the curing of step (g) is for 24
hours.
3. The method of claim 1 wherein the barrier material comprises a
mixture of a liquid binder including an adhesive and a plastic
cement, fiberglass fibers, lightweight aggregate, water and
optionally, a hardener.
4. The method of claim 3 wherein the fiberglass fibers are
fibrillated polypropylene microfibers.
5. The method of claim 1, step (c) wherein the liquid adhesive is
sprayed on.
6. The method of claim 1, step (d) wherein the barrier material is
applied by hand.

landscape in a desired configuration of the bunker having a liner,
an interior surface, a top edge, a lip, an opening, a floor, sides
and turf surrounding the bunker opening, a hinge point around the
top edge of the bunker such that there is approximately a 45 degree
angle formed by grading the bunker top edge and the turf

Description
BRIEF SUMMARY OF THE INVENTION
[0001] The present invention is a product, and a method to create a
solid interface (or barrier) between soil and the sand of a golf
sand bunker.
BACKGROUND OF THE INVENTION
[0002] The present invention is a material and method of forming a
liner for the stabilization of soil and forming and underground
liner for sand bunkers.
[0003] The present invention is a product and a method to create a
solid interface (or barrier) between soil and the sand of a golf
sand bunker. This barrier, or liner, exhibits unique advantages
over other liners or lining systems. The liner can easily be
adapted to the contours and nuances of the cut out bunker. The
liner material is somewhat porous, allowing water to percolate
through to reduce water accumulation and to keep the sand in place.
It retards weed growth thus reduces use of herbicides or hand
weeding. The barrier material is not rigid so that a ball strike
will not crack the barrier. The liner/barrier is flexible enough to
dampen, or absorb, the impact when a golf ball hits the sand making
for more realistic play.
BRIEF DESCRIPTION OF THE DRAWINGS
[0004] FIG. 1 is a side view of a preferred installation of barrier
material and construction of a bunker in accordance with the
present invention.
DETAILED DESCRIPTION OF THE INVENTION
[0005] The barrier material. The material that is used to form the
barrier is a mixture of a dry adhesive, dry plastic cement,
fiberglass fiber, lightweight aggregate, water and for some
applications, a hardener. This mixture is applied by hand as a
semi-solid and allowed to cure. The mixture may be modified to be
used with spray application equipment. [0006] Preparing the soil 2.
The soil 2 is prepared by forming the soil 2 and landscape in the
configuration that is desired. It is very important to form a
"hinge point" 4 outside and under the top edge 6 of the bunker 8
such that there is approximately a 45 degree angle formed by the
grade going outside the bunker 8 and the grade underneath the turf
10 surrounding the opening of the bunker 8. By trial and error,
this 45 degree angle was found to allow the hardened liner 10 to
anchor and reinforce the opening of the bunker 8, reduce any
chipping of the bunker 8 by maintenance equipment and to allow turf
12 to grow over the lip of the bunker. Once this is formed, the
soil 2 is then physically compacted and then a liquid adhesive
polymer is applied to bind the surface of the soil. [0007]
Application of the barrier material. Following a stabilization of
the soil 2, the barrier material 10 is mixed and then applied by
hand being mindful to attain a three quarter inch (1/2'')-(5/8'')
thickness all around the bottom and sides of the bunker. The
barrier material is then continued on up over the top of the bunker
being careful to maintain the 45 degree angle and for at least 6-8
inches outside the lip of the bunker. Then the barrier is allowed
to cure for at least 24 hours after application. [0008] Finish
surface. After the barrier is allowed to cure, another application
of adhesive is sprayed on the surface and a layer of clean, dry
bunker sand is spread over the surface to form the faux appearance.
Allow (mandatory) 24 hours of curing and the bunker liner is
finished. Sand can now be applied as desired and soil /turf can be
prepared on top of the upper lip of the bunker. [0009] The bunker
8, includes a floor 14 where a perforated drain pipe of
approximately 4 inches to permit proper drainage. The drain pipe 16
is covered in approximately 3/8'' pea gravel 18 for drainage and
stability and cover the beveled key way 20.

ranges in the practical amount would reflect with normal conditions
using less amount and adverse conditions using higher amounts.
[0010] The formula has undergone various iterations to identify the
best and longest lasting composition. It has been found that the
adhesive needs to be a non-latex polymer type that is not liquid
but powder in nature for best suitability. The plastic cement is
necessary as a filler and provides the flexibility of the barrier.
The aggregate type has been found to have the best size and bulk
density to allow for the most desirable amount of hardness and
pliability. The overall mixture allows water to percolate through
making the barrier unique.
