Does anyone know the basic steps for building a house with a polished concrete floor
Basically, I am looking for info on the recommended thickness of the
foundation and the grade of concrete. The home will be in Louisiana on
pretty solid ground. l do not expect the ground to have a lot of clay. It
will be on the Northshore of Lake Ponchartrain; about 30 miles up from
there. I am looking for any information that would make this process
painless. The foundation will also havea lot of heavy concrete on it with
fireplaces, stairs and what not. l would really appreciate any advice!!
usually an engineer is required to provide calc is & spec is
for the necessary footing depth below grade, thickness & width. the
engineers details will also specify the concrete mix design as well as the
sizes & placement of the re-enforcing steel. check with ur local building
department many cities have standard plans for single or two story
footings & are often happy to steer you in the right direction. you will
probably need some plans & permit to build. i don't like sealers on a concrete floor because they wear off & need constant stripping & re-sealing to keep them looking good. if you want a decent shine off the shelf products like mop & glo are easy to maintain & inexpensive. there are companies that grind & polish concrete floors. concrete densifiers & hardeners are used to run the psi up to the point where the concrete will take & hold a shine. because concrete has a tendency to crack the mix design is very important. we use super plastisizers & water reducers in the concrete. also pour the concrete as dry as you can & still do a good job. if you see ur concrete crew adding more than a few gallons of water to a truckload it is usually a mistake. more water means more shrinkage which means more cracks. because concrete work is time sensitive, usually a narrow window of workability, there is no time to train or figure it out & still get a top quality job. i strongly recommend that you get some pros to help you out. don't be afraid to ask to see some previous jobs before you select ur contractor. anybody that knows what they are doing will have some recent work to show you.
There are getting to be lots of popular concrete finishes these
days. Some are just stained, sealed, & waxed. Some of the newer ones are
ground gound & polished.
There are companies that specialize in concrete finishes. I would go talk
to someone like that (with lots of experience), pick out a desired finish,
& get their specifications for the concrete mix. On the ground down
finishes, the size & color of the aggregate is important. And how much fly ash that is substituted for cement may be important for the durability of the finish. The thickness is likely going to four inches or thereabouts. The strength between 3000 & 3500 psi. That translates into about 5 sacks of cement per cubic yard. These things may not be as important for the final appearance as the color of cement & the type of aggregate or if you go with an integral color admixture.
