The deepest bunker in golf is named after a mountain range, and for good reason. It's called the Himalayas or Himalayan bunker, and it's a 40-foot-deep, 25-foot-wide bunker at Royal St. George's ...
Constructing good quality playable bunkers can cost up to $4 per square foot. In addition, you have to consider the maintenance it will require that will dramatically push your maintenance cost up. Construction of the bunkers could cost around $100,000.
Silica sandSilica sand is used for bunkers and greens on golf courses, as well as for natural and synthetic sports fields. Those sand traps you find yourself stuck in way too often when you're playing eighteen are usually full of silica sand.
A bunker product such a bunker blanket adds about $1.25 s.f., while some of the fancier products such as 'Billy Bunker' add about $2.50 s.f. The cost of the bunker sand can also varies from $40 per ton to as high as $90 per ton.

Golf course sands are different. They are made of round particles “resembling a bucket of balls with large pore spaces between each ball,” Kidd says. They promote good drainage, and healthy air and water circulation.
In fact the sand is actually quartz, a waste product of the mining process that takes place in Western North Carolina. The quartz is so pure that it prevents golf balls from plugging or burrowing into tricky lies.
Bunkers with intricately shaped, serpentine lines require a great deal of extra hand labor for edging and are therefore more costly to maintain. average total square footage is about 100,000 square feet, with the average size of a single bunker being about 1,500 square feet.
three typesThere are three types of bunkers used in golf course architecture and all are designed to be impediments to the golfer's progress toward the green.
Spruce Pine miningThe white sand in the bunkers at Augusta National comes from North Carolina, namely the Spruce Pine mining area of the northwestern portion of the state, near the Blue Ridge mountains. That region has been producing quartz and feldspar, which is a slightly less pure version of quartz, since the Colonial Era.
At minimum, sand depth should be 4 inches on bunker floors to prevent golfers from striking a liner or underlying soil while playing a shot.

Bunker is the proper term for what is commonly called a sand trap. Bunker is official terminology, sand trap is just what people say.”
Golf Association considers a list of eight factors when selecting bunker sand: particle size, particle shape, crusting potential, chemical reaction and hardness, infiltration rate, color, penetrometer value and playability. Depending on location and climate, how these factors are ranked vary slightly.
For many years, selecting bunker sand involved calling the local sand pit. Superintendents were often told, “We have mason sand, brick sand and concrete sand. I think what you want is our mason sand. That stuff would work great for you.” Mason sand might or might not be desirable sand for bunkers, but in the current golf climate, the days of calling the local sand pit are over. There are few places in the United States that have natural sand deposits that meet specifications for great bunker sand. Most premium bunker sand is manufactured in only a few locations throughout the country. These manufactured sands, along with a few rare natural deposits, make the process of finding great bunker sand difficult and expensive.
The amount of sand in a bunker also can be an issue. Golfers need to be reminded sand bunkers are a hazard, but at the same time, bunkers need to be a fair hazard.#N#The major issues with bunkers are sand quality and playability, and obtaining quality bunker sand, which isn’t easy.
Round sands can’t compact. Therefore, highly angular sand with low sphericity will obtain the best penetrometer reading and offer the best resistance to compression from the golf ball. This translates into a low tendency for a ball to bury in the sand, which minimizes the dreaded fried egg lie. Penetrometer value.

Gary Dalton , superintendent at San Diego Country Club for the past 16 years, says he’ll draw a picture for his Spanish-speaking employees to help them gain a better understanding of what needs to be accomplished.
Jason Harsh, superintendent at Memorial Park Golf Course in Houston, says he has learned key words in Spanish to work a little better with his employees who speak limited English. Learning the Spanish word for soil, sand, shovel, rake, etc., has been effective for him daily at his 18-hole, city-owned course.
East Lothian. We have excellent, natural course sand. However, over the winter some have been filled with sand to a depth of more than six inches whereas others have about two inches. Trying to hit a decent length from a fairway bunker with very deep sand in not easy.
On the pga tour they probably use crushed marble mixed with the pollen from a jade vine.
Sand bunkers are part of the strategy of the game. Utilized in strategic design a bunker is positioned in the golf hole to guard the desired position in the landing area or green . An alternate hazard free route is left for a safe and longer way to the hole. Penal design locates bunkers to create forced carries without regard to risk. Heroic design features bunkers, usually on the inside of a dogleg, that reward risky shots with a premium location in the hole. A variety of playing abilities is accommodated with heroic bunkers.
The functions of the sand bunkers are combined with aesthetic and artistic style by the golf course architect to offer a harmonious and consistent transition in hole difficulty and playability. Sand bunkers provide color, texture, depth perception and scale. All golf courses have a certain style or sense of place of which bunkers are an integral part.
Hazards should be placed on natural highs or lows of the site and should be visible from the approaching shot for tactical decisions. They also should be a physical and psychological landmark. Depth, height and width should vary and be in proper accordance with the desired severity of punishment for the mis-hit shot. An alternate safer path to the hole is important, as average golfers cannot consistently maneuver a golf shot over hazards. Hazard placement should also allow every golfer an opportunity to hone their skills. A course void of hazards is boring to play and not as aesthetic or satisfying to all skills of golfers. The length of the golf hole dictates the size and shape of the hazards in the progress of play, adjacent terrain and vegetation, and scale to its surrounds.
Bunkers evolve or change over a period of time. The average lifespan of a bunker is twenty to twenty-five years, depending on climatic conditions, original construction and maintenance practices.
Proper planning and construction can achieve favorable results by retaining or rediscovering the original character of the golf course. It also increases efficiency of maintenance and course attractiveness for years to come. Upon completion of the analysis, work toward renovation can begin.

One of the more popular methods to clean existing bunker sand is using a sand sifter. There are several effective options available to perform this process, ranging from more expensive machines to less expensive hand tools.
While bunkers can add strategic and aesthetic value to a golf hole, they can also be a source of dissatisfaction due to their placement, appearance or condition. Bunkers are arguably the most dissected and disagreed upon feature of a golf course. The way a bunker should look and play is seemingly always up for debate.
If cleaning sand is not an option, either because the sand is too contaminated or because the process will be too time consuming , adding a layer of new sand on top of the current sand can provide some relief – although very short-term relief and with mixed results.
Many courses recognize that their bunkers are failing, leading to playability concerns and dissatisfied golfers . However, because of limited resources they are not able to replace the sand, install drainage or make architectural changes.
Based on current technology and field experience regarding bunker construction, installing a liner – either a durable liner or a sod liner – is a good idea to keep native soil and rocks from migrating into the sand. The difference between lined (left bunker) and unlined bunkers is tremendous.
In the absence of functioning drainage, bunkers will remain wet and likely play firmer than desired. With heavy rain or irrigation, water may pond in bunker floors and require significant labor costs to restore normal playability.
Rather than an exposed soil edge, wrap sod over the edge to cover the soil. This will reduce the amount of soil and rocks that fall into the sand.
