The foundation of the strip of all types of existing foundations is the easiest to execute and costs. It is popular in the construction of baths, private houses, cottages with a basement device, warm underground, while you fill the foundation, and you have nowhere to live, we offer you to listen to our site – Verisna, where upon request:
I will rent a Kyiv apartment for rent, you will find a lot of offers. For this type of foundation, an indispensable dry soil is most suitable. Such soil when freezing and high humidity does not need deep filling. The insufficient depth will be the cause of cracks, both by the foundation itself and on the walls. The depth with a margin does not threaten the physical indicators of the foundation, but will cause an increase in financial and labor costs.
When arranging the foundation, you can not do without measuring theodolite. If it is not, then the grandfather’s method will come in handy: pegs drive in the corners, a cord is pulled, drawing the perimeter of the future house, and the trench is digging.
The first stage of the device.
A layer of sand is poured, trim, then a layer of crushed stone or gravel. The thickness of the layers is no more than 20cm. A layer of cement mortar is laid on top of up to 10 cm, and a technical break is made in the work – this layer is allowed to stand for about 7 days so that the solution gains strength.
The second stage.
Arrange a layer of waterproofing, for example, from roofing material on which reinforcing rods are laid along and across the trench, connecting them with a knitting wire. The reinforcement must be anti -corrosion.
The third stage is the device of formwork from boards, plywood, slate or glass deck sheets.
The fourth stage is the actual device.
When performing this stage, the weather state is of particular importance, or rather the air temperature. If heat, then the concrete of the brand “M200” is taken, if it is cold – brands “M300”, “M400”. Cold weather dictates the use of frost -resistant, accelerating the hardening of concrete, additives. The ratio of sand, crushed stone, concrete in the solution during manual work is maintained in a proportion of 3: 5: 1, respectively, the ratio of water and cement – 1: 2. Knead, observing proportions, and get high -quality concrete. It remains to pour the mixture into the trench.
