The porch is an extension to the main structure, should have a strong base — the foundation. The durability of the porch will depend on the quality of the foundation. The most common option is a columnar foundation made of brick, blocks or asbestos -cement pipes. It is easily executed and available in its cost. Initially, you need to prepare the site for the foundation. To do this, the upper layer of the turf is removed (the possibility of sprouting weeds is excluded), a layer of roofing material, sand and gravel is laid. Next, the recesses of a certain depth at a distance of about a meter under the poles are dug up. On dense soils, you can lay out brick or block pillars. On less reliable lands, asbestos -cement pipes are used, which are poured with concrete solution. Use sheet metal. The price is not high.
