As I built the foundation with the ground floor this summer
This summer I built the foundation and the ground floor for the monolithic house. First of all I had to prepare the land for construction: cut down a few trees, did the layout.
The site was sloping. Dug pit and started to do "cushion" for the foundation base.
Fundam cast slab 270 mm thick. According to the project was laid insulation 100 mm, I was expelled because it makes no sense to insulate the entire basement area, because the frost is always coming from the sides.
Rammed sand 150 mm thick, 150 mm - instead of gravel and concrete preparation for all laid a waterproof membrane Planter.
Why I chose instead gidromembranu concrete preparation? In fact, everything is simple. By itself, the concrete preparation nothing of itself is not, it is not reinforced, it assumes no strength, with the foundation of the structure point of view. Concrete preparing - it's just a convenience for construction, no more, besides the cost of the work and the material will be much more. A membrane is a very practical and inexpensive material that is easy to install and very inexpensive work.
Further, IMIS laid tier 2 ribbed rebar 12 with a diameter of 200 mm unit. I advise you to always buy dimensional reinforcement. Exposed timbering, we check the size, tilt, and submitted concrete.
Concrete eventually came out on 7 m3 more than in the project. I suspect that just from the factory as always dolili. Therefore, all future recommend that you first find the actual geometric dimensions of your foundation, which turned out in fact and not in the project, or somewhere on the sheet. Calculate what should be the volume of the concrete after the fact, and then think where are inconsistencies.
Foundation tinuous 4 days and started pounding the formwork.
Bottom section height of 2.7 m, so do the formwork of the board was not the right decision. In addition to the inconvenience most of formwork installation, inconvenience concrete appeared in the future, had to be poured out in 2 stages, and this extra money. All tip for the future: it is better to rent a team, professional formwork and pour all in a single step, believe it will be much more effective and safer. Yes, I admit, is a little expensive, but it is better to invest right now how to money than to get unnecessary problems.
After concreting the walls of the cap, left alone the construction site for a week, given the strength of the walls to gain. Previously did not take a chance to take the formwork.
A week removed the formwork were shortcomings in some places, "shells", had to cover up with a solution. In general, the wall looked at 4 points out of 5. Further waterproofing plastered into 2 layers, sohla day. And then laid Epps 100 mm. In this case, Epps was necessary, it is thus protected from the cold basement.
Drove a tractor executed backfill, and this is my building in this season is over.
