  • After trench will be dug goes further its preparation.First is filling to the bottom of a sand cushion thickness of 100 - 120 mm. Its definitely need to stamp carefully.
  • next layer poured gravel or broken bricks, which also sealed hand-rammer.
  • Next around the perimeter of the trench is laid waterproof, which should go on the soil surface at 40 - 50 cm, as it should be shut down not only the inside of the foundation, but also the formwork for aboveground its parts.
  • on waterproof film set Welded reinforcing structure, which should follow the shape of the foundation, and full height.
  • then filled with coarse concrete reinforcement solution from cement and gravel, by ⅓ the height of the trench, and after solidification of this layer is poured next - one second remaining height.
Installing formwork for strip foundation

Installing formwork for strip foundation

  • After pouring of this layer, you can enjoy the wooden formwork of a device for the formation of the aerial part of the foundation - the cap.Waterproofing film left inside the casing, straighten it by walls and fixed on top of them, so that it does not slip into the concrete.

Work is performed in several stages:

  • first step is layout chosen for the extension area.Columns must be within one and a half meters from each other.

  • dig pits for each post individually.Their depth should be 500 - 600 mm square with a 500 × 500 mm. to the top of the hole should be somewhat expanded - approximately 100 mm on each side.

  • If post-support will be built of brick, the bottom is recommended to put a layer of coarse cement mortar.Just waiting for it pour, make the brickwork.
  • If the columns are concrete, the bottom of the wells installed reinforcing structure and the formwork to a height of a future column. film waterproofing allowed inside formwork and fix it on top ;
  • in formwork concrete is poured in layers.Each layer should be adequate time to cure before the next filled ;
  • Be px Article olba well leveled and sprinkled daily with water to pour ;
  • After poles will be ready with their formwork is removed and they are waterproofed roofing material, which is bonded to the heated bitumen mastic.
