Houses made of permanent shuttering - fashion or a rational approach ?

Why is convenient to build a house of permanent formwork?

In order to build a house of permanent formwork, heavy construction equipment is not needed.Fixed timbering made of expanded polystyrene.The big advantage of this construction technology is that the formwork subsequently also serves as a thermal insulation, waterproofing and soundproofing erected object.The width of the casing is about 25 cm.

This technology is advantageous to use in the construction of pre-fabricated energy-saving homes, as well as in areas where low temperatures are the norm most of the year.

Benefits application permanent formwork in the construction:

  • Due to its low density, this does not load the formwork foundation of the building.Therefore, from her house can be built on a medium deep foundations.This solves the issue of construction on soils with a high water table and save considerable resources.
  • House of permanent formwork, these concrete monoliths have excellent seismic resistance and resistance to wind.
  • Styrofoam - is a non-combustible self-extinguishing material.Decking out of it provides fire safety at home.
  • formwork This does not rot, it is not destroyed by termites and fungi.
  • material from which the formwork is made, does not absorb water.
  • This modern technology allows to save money.

Disadvantages application:

  • attachment to the seasonality of the construction, asthe construction of walls of the material is poured into the concrete at low temperatures there are problems with its hardening.
  • summer at high temperatures is also necessary to create good conditions for concrete curing, for example, moisturize it.
  • Mandatory grounding object.Building on this technology involves the use of iron fittings, so in order to avoid falling into the building lightning, it must be grounded.
  • Forced ventilation.Due to the fact that polystyrene is practically a vapor in the house will have to install a ventilation system.

House of permanent shuttering - the choice is made, start to work

If we consider all the pros and cons of permanent formwork, it is necessary to recognize that this construction technique is very interesting and promising.And its prevalence has just begun.Construction of houses from permanent formwork - is, of course, the next step in the evolution of the construction.

built cottages, permanent formwork which allows seriously save on insulation and payment for energy services, it is easy.When building with this technology do not even need a special tool , you can do that is available from any host: hand saws, hammer, pliers, knives, electric screwdriver, container for mixing concrete, shovels.

At the time of construction of the walls of the formwork at the construction site has to be made of the work:

  • by pouring the foundation to the binding releases the vertical fittings;
  • made horizontal waterproofing of the foundation;
  • marked on the surface of the foundation provided by the project place the openings;
  • made installation of wall mounting beacons.

Construction of houses of permanent shuttering - assembling their own hands

After all the preliminary work can begin immediately to installation permanent formwork units.

  1. Stacking blocks is carried out on hydroisolated and accurate horizontal foundation.When installing the first row of blocks is passed through the cavity rods vertical reinforcement, fastened to the foundation.The special grooves fit blocks harvested in advance horizontal reinforcement.
  2. Installation of the second row of blocks is carried out on the principle of conventional brickwork.This allows very hard to fix the structure of the form.
  3. third row - control, is carried out on the vertical alignment of the blocks of masonry jointing.
  4. When installing blocks of permanent formwork concrete experts recommend no more than 3 units of rows.Concrete is prepared here on site.After pouring the first three rows are placed and concreted the next three.
  5. important to know that you need to start pouring concrete at the corners, openings, slopes, and then pour the rest of the wall.
