But after weighing all the "pros" and "cons" you decide that your future home basement needs.Now let's see how better to use the method of construction.
Consider the two most common options
It begins with a pit to be dug with a margin of not less than a meter.Then, at the bottom of the pit put a mixture of sand and rubble.The foundation of the house is a monolithic slab of reinforced concrete that is cast on the prepared "cushion".Basement walls made of concrete foundation blocks according to the draft.Above the basement is usually overlap with concrete slabs that serve as the ceiling of the basement floor, while the
In this technology, with all its advantages, there are also significant drawbacks.
Firstly, the construction should be carried out fast enough to avoid dislodging the walls of the pit.This means that a basement is almost impossible to build their own forces or small teams.And only if the use of heavy construction equipment: Excavator, truck, crane.
Secondly, the special requirements for the quality external waterproofing, as when laying blocks on the solution are always microcracks.And the wall of concrete blocks are not airtight.
Thirdly, the ground near the walls of the basement already does not have the density, as it was in its original form, before excavation.It becomes more hygroscopic, so the walls of the basement collects water from the surrounding soil.Make additional waterproofing is expensive, and therefore it is not too often.
turns out that the basement will be in a kind of mud bath as long as the structure and density of the soil is restored.This typically takes several years.All these factors significantly raise the price of construction of the basement.
first foundation is marked according to the project, and then dug a trench to a depth of approximately 2 meters and a width of 50-60 cm. The bottom line is that the future of the basement walls are poured directly into the ground, and serve as both a foundation.First, do the formwork on the level of height of the cap or base spread from a brick.Then, the trench is filled and reinforced monolithic concrete.The widths of reinforced concrete (50-60 cm) is enough to basement walls are watertight, and the water does not penetrate into the basement.The soil from the interior of the future begin to take out of the basement after the concrete hardens.
This option has a significant drawback - the need for rapid device trenches and filling it with concrete.But further work can continue even one person.Pause and then resume it, you can almost any time, without any consequences for the quality of construction.
Therefore, this option of building a basement is more convenient for self-construction.But what is the option of building a cellar to choose - it's up to you!
