melkozaglublenny How to make a strip foundation?The name of this small foundation because it does not reach the depth of freezing.These foundations are popular for a long time in Canada, the United States, Norway, Denmark and Finland.We are started to be used recently.
Melkozaglublenny strip foundation cheaper than usual 2 times.Now on such grounds construct buildings up to three floors, hospitals, schools and kindergartens.This foundation is not subject to stress during heaving of the soil.The trick is that the ground next to him does not freeze.Standard on melkozaglublenny strip foundation ASTM 32-01 was established in 2001.
Melkozaglublenny tape base goes into the ground only 40-50cm, but the trench is dug two times wider than the standard for the foundation.Insulation is placed here only extruded polystyrene foam or mineral wool on the basis of basalt.He adhered to the bituminous membrane on the entire surface of the foundation, and the bottom is bent at 90˚.When heat loss through the floor it is saved under a layer of insulation, which prevents freezing of the soil and do not swell.This method is used for heating buildings, domestic purposes, residential and industrial, cultural and other institutions.
With the construction of cold buildings, insulation is not fastened to the foundation, and is placed under the base around the perimeter.Geothermal heat does not promerznut ground and swelling also occurs.Columnar strip foundation strengthens the base tape on the corners, it also allows to immerse it in a small depth.First, put the poles, then filled the entire tape, using valves, tied with wire.Thus, a single design that combines all the advantages of tape and pillars, and eliminates the disadvantages.To increase the bearing area and to the pillars could not rise up, they extend from the bottom.
columnar strip foundation will reduce the bond strength of the side walls of the foundation with the frozen ground, and these forces are quite considerable and may reach 6 tons per square meter.All communications through such structures summed easy as before pouring, and after it.Warming of the tape base element always favorably reflected in its subsequent operation.In such houses use space heaters are much less power.Houses do not need constant heating, if not used, they quietly suffer any temperature.
Strip foundation not flush possible to arrange only sand pillows, this greatly reduces the strength of swelling.It looks this item foundation of the house as a post or pile, laid on its side.It used only for one-storey houses made of beams, round logs or prefabricated panel houses.Under the foundation is always useful to do not flush the drain hole, two - three on each side.This type of foundation is used in areas with high groundwater, when everyone else to organize effectively.
not flush Strip foundation may consist of individual blocks at the corners and the middle of the log of his long sides.Stacking blocks and for the internal walls at the attachment to the outer supporting structure.The distance between them depends on the overall weight of the structure, on average, is 2 meters.When installing units or monolith under it is recommended to lay the insulation, do not destroy the water and retains its properties, the extruded polystyrene.Sand for pillows to be coarse or medium-grained, you can use boiler slag.
