How to pour the foundation with his own hands - advice and working arrangements

Construction of foundation - one of the most important and challenging stages in the construction of the house and any other buildings.Strong and smooth walls, floors laid reliable now.The process of laying the foundation of a multi-stage, and it can be divided into the main stages (on the links available for detailed instructions):

1. markup future foundation at the site,
2. digging a trench for the foundation,
3. waterproofing and drainage foundation,
4. construction formwork ,
5. reinforcement ,
6. pouring the foundation.

Pouring the foundation - the final step in its construction, after it corrected many flaws it is practically impossible, so we need more time to consult with the structure of the plan believe the correct location of the trenches and the formwork, reinforcement quality.Make sure that the left channel in the form of pipes for ventilation and the subsequent supply of communications to the house.

not skimp on the concrete!

for pouring concrete is best to use a ready-made concrete factory, the quality of which is higher than that of a self-made - in this material are not worth saving.Order it better grade of not less than the M200.Estimate how much concrete you need to, you can measure the depth of the formwork or trench, its width and length, the latter can be done on the plan and cross-check the data on the site.All three parameters are recorded in meters and multiply, and the resulting number is the necessary concrete cubic capacity.For reliability is added to it to 5-6%.

Before pouring the solution to make sure it does not dry and plastic.For truck mixer should be provided with access to every corner of the foundation, fill the formwork from different angles faster, and the concrete is evenly distributed.

Filling: notes

poured concrete for the foundation needed at one time, it's yet another reason to order the mixer with a ready solution.If this is not possible, then poured in parts, but not horizontal layers, and individual sections.Formwork vertical webs overlapping separating portion that can be filled at this time.Later, during the filling of the neighboring area, the jumper is removed, the concrete in the place of the future joint swelling moistened with water, you can even treat it abrasive to improve subsequent adhesion.But such a structure would still be less durable than the foundation, filled at a time.

foundation poured layers of 20-50 cm. Each layer is immediately distributed, leveled and compacted.To do this, use a special vibropress, and in his absence from the board or platform, "trowel".Before provibrirovaniem drop in certain areas should not exceed 10 cm. From time to time you need to rattling wall formwork that the concrete distributed in all the gaps.When the tread surface to the liquid layer, the process can be stopped.Such a seal can remove air bubbles in the solution, resulting in a stronger foundation is obtained.

When the previous layer tamped immediately poured next.And so long until the required height is reached.The direction in which the concrete is poured, in all layers should be identical.The last layer is leveled and carefully checked by level.Flooded basement is left for a few hours for the shrinkage.

foundation

Drying Concrete dries unevenly, most likely on top.If the top layer dries out prematurely, it can be covered with cracks.To avoid this, the foundation on drying time sprinkled with wet sawdust or cover with a damp cloth.Over pull plastic wrap to retain moisture.

Dries foundation from three weeks to a month, depending on the weather.In hot and dry weather it will have to moisturize frequently, with crude - also cover the film, but to protect them from the rain.After drying foundation formwork can be dismantled and proceed to the next stage of construction.
