Project (Our Basement)
Here
I (Greg) am at the dirty end of a concrete pump, for the first time
ever.
This is my first experience at pouring concrete forms of any
kind.
The pump operator guides the boom via a remote control. Note the
"S" turn on the end of the boom. The S turn slows the concrete
down
before it enters the forms. The S pictured is 4" in
diameter.
A 3" diameter S is recommended. Even with the 4" S, no blow-outs
occurred. |
| Pumping
concrete into the wall below a mechanical pass-through. Large
openings
(doors, windows, etc.) are framed out with pressure treated 2X10s,
V-Buck
(a vinyl 2X10) or galvanized steel. Openings are created on the
lower
side to provided for the pouring of the wall below the opening. |

Here's
a look at our simple bracing. The bracing extends out to ground
level
at right (not pictured) and is required only on one side, just to keep
the walls plumb. The steel within the forms braces the forms
against
blow-outs. Our basement is about 7' below ground on this side and
at ground level to the rear. 2X4s are all that are required for
bracing,
but we used rough-cut 2X6s because we all ready had them.
Pictured
near the top of the forms is a reusable metal brick ledge form.
Holes
are cut in the forms allowing the concrete to flow into the
ledge.
In this case, we are using the ledge as a support for a concrete
porch.
That's my Dad to the left. |
| Finishing
up. We are done with the pour. 30 yards of concrete, 200
running
feet on wall, 10' 8" high walls, no blow-outs and all in less than 3
hours!
That's pretty good for a bunch of do-it-yourselfers on there first
try.
That's my Mom on the right and her first cousin to the left. Love
that family labor. |
