Last evening we applied two coats of the first step of cement sealer. The first coat went on with paint brushes, inch by inch, working it into the pores of the shotcrete. The second coat was applied with a garden sprayer to get a uniform coat over the entire surface. This evening, after 24 hours dry time, it gets the second step, two coat application..... and then 'it' is done and sealed.... I Hope!
In the middle of one of the worst dry spells in the States history.... I power washed the concrete some 4 times over the last week or two. Days away from application of the sealer we get the worst Gully Washer storm we have seen in the 7 years we have owned this property. Living on the side of a Rock.... run off is one of my intended fill techniques for this pond. Snow melt, gentle spring rains, a quick thunderstorm in the summer (nothing stays overhead here for more than a few minutes, everything is fast moving), a nice trickle to keep it topped is the plan. THIS storm, this one had the 3 foot culvert where our driveway bridges a gully, FULL, with the water threatening to back up and overflow the drive! The gentle trickle planned to top up the pond...... Three more days of power washing to remove the hillside debris from the nice clean cement I had prepped and ready for sealer.
Lessons learned: Some sort of a separation basin is required to filter out the debris from the run off intended for the pond. I had the bottom drain screen removed so I could machine up a flange to make a multi point, low level filter inlet. It is now known that a Pine Cone makes an excellent 'stopper plug' for a 2" bottom drain... knowledge is power I guess.
Knowing that there will be sediment in the bottom low point drain area of the pond, my intent is to come vertically from the pond floor, 'T' to a smaller sized pipe leading to the shallow side, 'T' again directly above that for a main pond low level inlet (with a gate valve to control flow in), and then up to the top for a fabricated floating skimmer.... design yet to be determined. Due to the nature of what sure will be a changing water level, I need to make this telescopic to adapt to those changes. Minds Eye designing techniques, I couldn't come up with a 'hose' that would be flexible enough to allow for the varying water levels, and still not collapse under the suction of the intake, telescopic is the only idea I have come up with so far. As that pick up would now be rigid in a horizontal plane, now I have to come up with a trap door in the deck overhang to be able to easily clean out the skimmer intake as it would be mounted directly under that. Oh Joy, design changes to the deck once again........
At least I can see water hitting this "Hole" in the coming week! Doesn't matter to me if its clear, moving or with a waterfall and stream..... just so long as the Hole is filled with Something! The rest will be a "work in progress" and turn back into a Labor of Love. At this stage.... I thought a Boat was the biggest black hole in the water to throw money into..... a fool I am..... the "Hole" itself that floats the boat is a far bigger drain! Sure would have been more cost effective if we had "dirt" where a hole could have been dug... building an above ground hole on the side of a hill is an eye opener... what was I thinking?!
