How warm pile foundation from the outside - the choice of technologies and materials

One way of saving in the construction process - reducing the cost of equipping the building foundation.This article is expenditure on average is about ⅓ of the total budget.This is one of the main reasons why many private developers prefer to pile foundation.

its advantages in a separate article, and all considered conclusive arguments.Still, there are a number of drawbacks, and one of them - is very significant.The fact that the overlap between the lower floor (flooring) and a ground clearance remains.Simply put, under the structure literally "the wind blows."It primarily affects the atmosphere in the room and makes it necessary not only more intense heat a building, but also artificially prolongs the heating period.Accordingly, increasing operating costs.

This article addresses the issue of thermal insulation of the foundation piles at home, which is already in operation, and has been built without a raft foundation.

This additional event - the optimal solution to the problem of increased heating costs.Individual investments will pay off rather quickly, especially as the complexity of the insulation process is no different, and the materials required for this are relatively cheap.Well, that, given the specificity of this design, trim the insulation layer can be made only from the outside, on the perimeter of the building, no need to explain.

Where to start?With

that prepare the surface on which the insulating material is recorded.The owners, who advance thinking on this issue and still in the process of building erected grillage, this item is uninteresting and is not necessary - they're done.The only thing they should do - check the status of this "tape" and eliminate possible defects in the form of gaps between all of its elements and the lower crown (base frame).

But what about homeowners buildings which stand on stilts alone?On the internet you can find many options such equipment bearing surface.I recommend something like the only right would be absolutely wrong, because not only every building, but land characterized by its own peculiarities.It is logical to consider and analyze the feasibility of each of the methods of construction of a "wall".

Masonry

Basically, the problem is not so complicated.Between the piles off a shallow trench, the bottom of which is sealed, and set formwork.Given that the distance between piles is usually not more than 2.5 m, such a structure (2 + jumper boards) can be reused by transferring it from one place to another.

This frame is filled ASG (about 10 cm), compacted and then filled with concrete solution.In fact, it is common melkozaglublennaya tape.The only difference is that the load on it - the lowest since the house hold of the pile, and it is intended only to perform a support function to a brick wall;and single-row will be enough.Therefore, any special requirements for sand cushion or brand is not concrete.As a filler for concrete block even possible to use the solution.The main thing that the artificial stone can withstand such a small load.

But this is only one drawback.There is a second.Everyone to be able to independently put a brick?I guess, yes.And so, to get a smooth wall, with no obstructions or distortions?Probably not.If there are no practical skills mason, it is unlikely to help plumb, level and expensive laser levels.A curved surface oblitsevat insulation material is problematic.Even if it is mineral wool, it will be necessary to hold a number of rather complex additional measures for its exterior design.Hence, it is necessary to invite (and pay for labor) specialist.Is it rational to you, dear reader.

frame

From any point of view, this option is better.To build such a support structure is quite simple, the more so that the side and top "ribs" are already available (piles and base frame).The only thing that you need - the right frame material.Metal

rail guides welded to snap piles, as well as the vertical in between, over the entire length.But in this case, when the support legs of the metal base.And if as piles used asbestos cement pipes (with concrete filling)?This is the first restriction in application.

now how to fix a heater.You can directly in the frame, can be pre-close it, for example, particle board.But in any case, have to deal with metal drilling as insulation sticking to it will not work (limit №2).The process is quite long, especially if thick slats.The construction of a durable, tough, but "iron" is not for sale cheap (limit 3№-already on the money).

Wood

only drawback - rot.But you can extend the service life.

Firstly, all rail impregnate qualitatively (antiseptic, machine oil) and dry.

Second, the paint on all sides, including butts, water-repellent composition.Acrylic paint is quite expensive, but in fact no one did not make it to smear a thick layer.In principle, the entire frame a 5 liter capacity is enough.

But here arises another question - what to use as the lower guide?Best of all - bar, also pre-treated.It is enough half to dig into the ground (between the piles), and additionally secured with a pair of vertical pins (for example, scrap reinforcing rod).This prevents displacement of the workpiece in a horizontal plane.

And how to make himself a framework to solve difficult.You can fill the uprights, which is attached to a heater.Another option - to establish chipboard, MDF, sheets of plywood (with a catch on the top and bottom edges).Previously, these materials are also processed (impregnation + coating).

The result is a perfectly flat base, which is easy to decorate any insulating material.

How to choose insulation

Once it comes to the budgetary process that will focus on the cost of production and the possibility of performing all operations on their own.Often there are recommendations on the feasibility of polyurethane insulation.But it will need special equipment, therefore, without the services of "pro" can not do.

best option - penoplex.From conventional foam it is more "rigidity", and given the fact that the insulation is made on the outside perimeter, it fits better.Mounting plates made landing on the glue with additional fixation of special nails.Such expendable items are cheap, but they are many and do not need to, since the height of the dummy cap is negligible.

on the usefulness of advice in the use of mineral wool having some doubts.Firstly, it (irrespective of species products) gradually absorbs moisture.Secondly, it is necessary to coat the more expensive materials, such as the plastering of "soft" surfaces is not done.

Much depends on how the front is supposed to produce the resulting finish cap.But the main "targets" for the reader on the insulation of the foundation pile is already marked.The final decision - for the owner of the house.

After work on warming is necessary for the structure to install perimeter flow.They prevent the ingress of rain drops on the newly mounted wall.
