The Concrete Was Key
A foundation like the one for this home would typically
take a minimum of three days to complete from start to finish. On day
one the footings would be set up and poured and on day two the same would
be done for the walls. The walls would then need to sit overnight before
the forms could be stripped away. As you can imagine, trying to condense
this process into a 12 hour timeslot was a challenge. Careful planning
was a must, but that was only the beginning.
A proprietary concrete mix supplied by Bend Industries was key to the success
of the project. The concrete was designed to reach 8,000 psi after 28
days, which is twice that of the concrete used for our standard foundation
walls. Even more important was that the concrete had reached 3000 psi
in strength only four hours after the walls were poured. To put that into
perspective, the code requires that a foundation wall reach only 2500
psi in 28 days.
This allowed the carpenters to begin quickly decking the home. The foundation
was backfilled less than ten hours after the wall pour. When using our
standard concrete mix, we recommend waiting a week to ten days before
backfilling a foundation for best results.
Coello & Associates’ utilization of Durand aluminum forms with
attached hardware also aided in the fast construction of the basement.
This advanced forming system helped the crews set the walls both correctly
and extremely efficiently.
While the perfect concrete mix and superior forming system were instrumental
in constructing the foundation on time, it also took the determination,
skill, and hard work of 36 individuals to truly make the project a success.
Coello & Associates is thrilled to have helped fulfill the dreams
of the Koepke family!
