Boulder Above Ground

The first "pondless waterfall was designed and built in Fallbrook, California in early 1980, long before the advent of rubber or coatings PVC pond. However, this particular design is known as a cascade "childproof" with its descriptive name giving a better definition of its role and purpose.

This design was the result of solving the enormous liability issues related to small children drowning in bodies of standing water such as pools and ponds. The client wanted a waterfall in your garden, however, there was no possibility for a pond due to topography and space restrictions. In addition, building codes restricted depths of the pool to 18 inches, unless all code requirements were satisfied, such as coastal body of water with about 6 feet, a requirement for special door and door alarms, to name a few.

The client also stressed to me the importance of low maintenance. A pond, regardless of their depth, it becomes a sink for blowing leaves and debris. Others maintenance factors including the growth of algae from water exposure to sunlight, and evaporation resulting from increased surface water area.

By capturing the water in a tank underground waterfall, all code requirements above and maintenance problems are resolved by removing the cause.

The pleasing results are sound and beneficial view of a waterfall, less liabilities, or the high cost of maintenance. As water poured through of rock placed on top of galvanized steel mesh that covers the collection basin (tank), the collected water stays cooler. And in the absence of sunlight, no problems with algae. By placing a thin cloth between the galvanized hardware loose rocks and covered with galvanized grid, leaves and small debris are prevented from finishing in the collection basin and can be removed easily by hand.

This "child proof" or pondless waterfall was built of concrete of 3500 psi (with stealth fiber in the original) and reinforced with rebar # 3 # 8 "on center. This type of construction is to survive earthquakes and last for decades. Shells reinforced concrete are properly sealed with concrete sealer as Thoroseal ® not only permanently waterproof concrete, alkali will prevent the and phosphorus leaching into the water, so it is permanent insurance for aquatic life.

Most modern "pondless" breaks water is constructed with rubber or PVC coating. Pond advocates tout the active line of coatings such as faster and cheaper to build, even claim shirts that last longer than concrete. line ponds and waterfalls can be faster to build, but are not necessarily cheaper or stronger. An example: In August 2007 a previous client of mine in Rancho Santa Fe, California told me they were buying a 15,000 square feet on three acres.

They asked me check out a waterfall and an existing pond on the property. The previous owners were informed that a shipping company had paid $ 276,000 to build the pond, only to leak a few months. Water loss was so great that they had to close. The type of line went to inspect, pointing to a rodent burrow mound between the rocks and boulders around. He said it was gophers, ground squirrels or rats, or possibly all three, who had chewed a hole in his shirt. Quickly added that the investment was a guarantee against manufacturing defects only, but not acts of God, man, beast, or reptile.

As What's more, a second shipping line was called out and paid $ 75,000 to repair the leaks, who tried to make the plaster around the base of each rock in the waterfall. FEO not adequately describe it. Talk about turning a tropical paradise in a tropical nightmare! In the two months that filtered worse than before.

I was in charge Crane out all the stones from two to five tons and remove all the remaining smaller boulders and stone with a Bobcat, then start all shirt and replace it with 3500 psi reinforced shotcrete.

width of the chute was doubled to 40 feet has been added to your height, double width the lagoon. The original 2-hp pump was replaced with five pumps of high efficiency 3-horsepower, the 12 lights were replaced by 65 accent lights. All this was completed $ 40,000 less than the original cost of the pond and a waterfall. (Note: The total amount paid by a waterfall in the original construction costs and replacement costs was $ 586,000. More than half a million dollars! So it's a liner is actually more expensive than concrete?) Took the original line type twelve days to complete the project, but we took only five weeks.

So much cheaper and longer lasting … What about liability or active? Each stone and boulders across the waterfall and the pond was secured in place with mortar, unlike the line falls, where rocks and boulders were placed in the approximate shape and coating can easily move or tear down when we move on, creating an extreme liability.

In light of made before comparing the line construction with reinforced concrete, ponds and waterfalls line can end up costing twice that in considering the costs of replacement and repair. "Most pondless waterfall defenders highlight three major selling points in the use of pond liners" pondless waterfalls " and koi ponds.
1. They are cheaper to build.
2. They last longer than concrete.
3. They require less maintenance. The truth … there is more profit made line for the kids pool. Are input and output in one or two days! Will they go back and fix the problems that will surely emerge, is the big question.

Liner ponds and waterfalls of "pondless" – are an asset or liability? Before investing your hard earned money, make sure you know the answer.
