Erected by increasing

This change ensures the strengthening of the connection of the block and adjacent adjacent structures, which as a result leads to a significant increase in the strength of the buildings erected by increasing the contact area of ​​the filling groove of the cement mortar. It should be noted that the amount of consumed cement mortar increases inconsistent, but the construction of the foundation is much stronger, and its service life increases. It is also important that the foundation blocks have high strength characteristics that exclude the danger of their collapse. Since the foundation blocks have medium weight, this circumstance allows you to use low -power technique for their laying.
