SLOPING BACKYARD WATERFALL PLUS

Consider sprinkling neutral-colored gravel or sediment on top of the drying foam.

If you're ready to, you can finish foaming and start your waterfall easily in the same day.

Give the foam at least 30 minutes, and up to an hour, to dry completely.

So if you're planning on introducing fish into your pond, be sure to use one that's specifically designed for use alongside fish.

Although other foam sealants can be used in place of specially-made waterfall sealants, they do contain toxic chemicals that are harmful to fish.

Start spraying only a little at a time as you begin the foam may expand more than you anticipate, and once it's applied, it's harder to remove en masse. Foam sealant works best on cool and damp stone surfaces, so mist your stream and waterfall if necessary beforehand.

Stream waterfalls require a stronger pump and a longer hose than pond waterfalls, because they need more pressure to get water back to the beginning of the stream.įoam in between any small cracks and crevasses using a specially-made dark foam sealant.

When the bottom third of the basin is perforated, graduate to a 1 inch bit for the middle third section, and finally a 3/8 inch bit for the top third.

After you've drilled around once, move up an inch or two and continue drilling another revolution.

Moving around the side, drill a hole every 4 inches. Starting from the bottom, drill a hole into the side of the basin using a 2 inch bit. If you need to perforate the basin yourself, the job isn't difficult. Basins need holes to allow the water to come in. Some sump basins will come already perforated, but many will not.Once the basin is set up, secure in place by adding layers of small - medium size stone (not gravel) around the basin.

Insert the pump to the sump basin, connect the water line, and make sure the hose extends all the way up to the upper pool. (See below for more instructions.) Place your sump basin into the excavated hole at the bottom of the waterfall, above the underlayment and liner. Drill holes into your sump basin if it doesn't already come with them.

5 ton of small (.5 - 2 inches) gravel per 10 feet (3.0 m) of stream, plus 1 - 2 tons for the upper pool and lower basin each 75 ton of medium (6 - 24 inches) rocks per 10 feet (3.0 m) of stream

1.5 - 2 tons of large (12 - 24 inches) boulders for upper pool and lower basin, plus 2 - 6 tons extra for 10 feet (3.0 m) portions of stream that are above ground.

Here's what you can expect to order when it comes time to buying stones for your waterfall:.

This is a much more reliable way of getting exactly what you want, as opposed to merely ordering a kit and hoping that the stones are ones that will look good in your backyard.

Visit a 'rock,' 'quarry,' or 'gravel and stone' dealer in person to get a feel for what kinds of stones your waterfall might enjoy.

Generally, waterfalls contain three different sizes of stone: boulders, or larger stones, which frame the waterfall(s) rocks, or medium-sized stone, which serve as the connecting stones and gravel, which fills in the bottom of the stream and in between cracks and crevasses. So if your stream capacity is 100 gallons (378.5 L), a 50 gallon (189.3 L) basin and a 200 gallon (757.1 L) pool will easily accommodate the stream. Now, simply make sure that either your upper pool or lower basin holds more than the total stream capacity. Measure out how many linear feet your entire stream takes up.

Next, measure the total stream capacity.

Add to or subtract from that estimate depending on the size and depth of your proposed stream. If your stream is relatively small - say it's about 2 to 3 feet (0.6 to 0.9 m) wide and 2 to 3 inches deep - estimate about 5 gallons (18.9 L) of water per linear foot.

First, estimate the amount of water that passes through a linear foot of your stream.

(You don't want your garden overflowing when you turn the pump off.) Here's how do to that: X Research source Knowing just how much water passes through your stream and waterfalls will help you determine how large your upper pool and lower basin need to be.
