Build your own backyard waterfall

On the back waterfall support wall I carefully placed 8 of the styrofoam cooler boxes (tops down into the slab) along the longer back wall slab. In front and in back of the styrofoam coolers I placed some scrap sheets of plywood to form up the rear wall and contain the wet cement during the pouring. For the first layer of styro covered building blocks required approx. 8 bags of cement, mixed up in the wheelbarrow and the scooped out with a 1 gallon bucket and poured over the styrofoam cooler blocks...some cement seeped out but it adds to the 'rough' rocky look I was seeking...I didn't want it to look like a concrete wall with water!!

On the pond side of my project I needed to build up a retaining wall around the pond slab to hold the 'pond'. To do this I used additional styrofoam cooler boxes, setting them into the slab with the long edge making up the depth of the pond retaining wall. Over the top of the styrofoam cooler boxes I top wrapped with additional 1/2" wire mesh screen again as reinforcement. I tried to secure the wire screen to the top of the styrofoam cooler boxes by using bits of hanger wire bent into a rough staple shape and pushed it thru the screen and into the styrofoam box. It didn't work too well so I abandoned it after a few points were tagged down.

Around the retaining pond wall substructure I place 2x4' sheets of masonite board with the finished,smooth side towards the cement pour (to try and get a smooth wall finish). I forced the masonite sheets to flex around the perimeter of the outer and inner pond wall, with the styrofoam cooler set inside. Using stakes to support the weight of the concrete I used a bucket to carefully pour concrete around the cooler boxes and screening and filling the voids between the styrofoam boxes. It produced a thickness of about 2 inches of concrete surrounding the cooler interior and saved a ton of concrete!!

As you can see in the photos the work was done in stages, basically I would mix up two 80 lb. bags of concrete mix in the wheelbarrow and then pour into my forms. A short side note...I did this in the early summer in Florida....take plenty of breaks and drink plenty of water. The heat and sun really wore on me as I mixed and hauled.

So anyways the pond retaining walls soaked up about 10 bags of concrete (800lbs) and the the rear waterfall, first tier took another 10 bags of concrete mix.
