- blocks These are already ready blocks of material, which saves time.

Preparatory stage
The construction of the foundation from the FBS blocks is not an easy and time consuming process, it should be understood and responsibly treated and planned.
Although this type of construction of the foundation is considered one of the simplest, but miscalculations can be expensive in the years, when the house is already finished and burned.
You should choose the right time to build a foundation. Like any other, the foundation of the house from FBS blocks should be erected in dry weather, preferably in summer. If you are overtaken by an unexpected rain, then the process is better to be interrupted! Do something else and check all the measurements again, it will never be superfluous.
Analyze the soil on your site. If it's dry, infertile sandstone, then consider that you are lucky. If the soil is soft, then you will have to pay special attention to the creation of a cushion of sand and gravel.
Block is better to buy a small size, to be able to do everything yourself, without the involvement of technology.
When creating a foundation of FBS units, pay special attention to the accuracy of the marking and the holding of the piercing cords. When the trenches are dug, a sand pillow should be created at the bottom, as already mentioned.
It should be wider than blocks by 20-30 centimeters and be about 20 centimeters high. It must be properly tampered with. Then lay the geotextile over it. The next step is to put a layer of gravel about 20 cm and also tamper. Specialists also recommend making a monolithic belt belt and laying blocks of FBS.
Mounting the foundation of the FBS
blocks Before starting the installation of the FBS units with your own hands, it is necessary to cut the trenches with boards so that the edges of the pit do not collapse, especially when you deliver the heavy blocks to the installation site.
When building a block foundation yourself, it is worth remembering that the first to install blocks of FBS in the intersection and angles, as they are some kind of guide.
Do not be afraid to constantly check the accuracy of the location of key blocks and the correct location of the pier. Lift it is a little, after each row of blocks, checking the evenness of the entire line.
There is an acceptable error in the construction of the foundation, but if you are in doubt, it is better to remodel now, making a more accurate and qualitative foundation.
To lay the blocks is a brick method( you can see the photo on our website) and add a waterproofing additive to the solution, which will increase the service life of the structure. It is necessary to do armopoyas on each row of blocks.
And do not forget about the technical holes for communicating to the house! However, all this should already be in your project.
Also, do not forget to provide a reliable coating that protects the block foundation from moisture and external influences. For this, bitumen mastic is quite suitable.
