Foundation for the furnace - the rules and advice for its strong "health"

Foundation for the furnace does not forgive mistakes

zero cycle works traditionally "eat" 25-30% of the total construction budget.Many, right?But the economy is not pertinent, as a healthy "root" - the key to the integrity of the entire "plant".

Foundation for the furnace is made in the form of a solid base plate, and it should not be linked to the base of the building.But its depth depends on three main factors:

• height of the aquifer;
• soil type;
• level of soil freezing.

All this data is extracted during the geological exploration area, where experts by drilling out of control wells receive samples of soil, water, and make the appropriate analyzes.Procedure fee (from $ 50), so many diy build risk "by eye" or guided by traditional methods (eg, Willow frame).Guess we not always so weak a foundation under the stove showing its "dissatisfaction" with such symptoms:

1. through cracks in the shell.
2. Partial destruction of parts of masonry.
3. Violation of the integrity of the chimney.

The main feature of these defects - breaking can not be repaired.After the restoration of the furnace cracks and collapses repeated that directly indicates incorrectly laid the foundation.Here also remember the "good" with its pseudo-savings - but too late."Gentle" repair of furnaces of bricks with a weak foundation can not be made.We'll have to completely demolish the machine and redo it again.

How do the foundation under the stove?

For those who are afraid of the complexity of the zero cycle works, it is useful to recall how hard worked on this phase of our ancestors: they are massive logs harvested by hand and customized them to each other in order to achieve the proper support for their "nurse."

Now diy arsenal, there are two methods available to receive a strong foundation under the brick kiln:

1. plate assembly. as building material use small concrete blocks, brick or ceramic.
2. plate Fill. The base is formed of concrete solution, into which the rigid frame of the river rubble or iron fittings.

drenched monolithic slab - the cheapest and most reliable way to build the foundation for the Russian stove-heater for the bath.Its seamless design is ideal for protecting the base from attacks by seasonal soil "unrest", and compared to the teams for this zero-cycle budget is reduced by an average of 30%.And the foundation slab of masonry bricks or blocks requires targeted actions mason-builder.

have monolith and cons: stove must stand alone for at least three weeks.In principle, such a delay in construction - not a problem.For example, if the foundation for settling of bath furnace, during the technical pause builders engaged in finishing works in the steam room.

So how to make the foundation for the furnace to quickly, many builders use special concrete admixtures to significantly accelerate the solidification of the plate (7 days).

diy instructions for how to make the foundation for the furnace

To describe the progress of work, we have chosen the monolithic furnace foundation, reinforced reinforcing rods, as this kind of the basics - the most popular among the Homebrew.Remember, the base plate must be 5 cm wider than the stove body.

1. Prepare a hole for the foundation.The dimensions of the pit further increase by another 15-20 cm. This margin is needed for correct placement of the filter casing and the side layer of crushed stone, sand and brick battle.pit depth is calculated according to geological exploration (allowance is added to the filter "pillows").
2. Puts sand "cushion" for the foundation .At the bottom of the pit is filled 15-cm layer of sand that is carefully tamped.To prevent shrinkage, it sheds water as long as the filling level ceases to drop.In the process of compacting the sand to be refilled to the correct mark.
3. Puts crushed stone filter for the foundation. on compacted sand fill a 20-cm layer of crushed stone mixed with brick fight and middle-sized stones.Stone "carpet" lightly sprinkled with a mixture of sand, to fill the voids formed therein.For better penetration of sand into the water as needed.Then spread a 10-cm layer of finer gravel and covered with a filter resulting "cushion" double layer of roofing material.
4. Installing formwork.Along the perimeter of the pit establish solid plywood (or wooden) "fence" that every 50 cm strengthen backup.Between the edge of the pit and the formwork must remain at least 10 cm of free space.
5. Bookmark reinforcing mesh. poured concrete pit bottom (starting layer of 4-5 cm), which will serve as a support for the "skeleton" of the foundation.As soon as he grabbed in the pit is placed in advance related meshes (on sale are ready sets).
6. Fill solution.Concrete preparing for a proven proportions: cement - 1, sand - 3, rubble - 5 and water.Before pouring the solution thoroughly moisturize the formwork, in order to prevent the absorption of water from the concrete tree.Working mixture is poured in layers (20 cm), gradually reaching the zero mark of the plate.Each layer is carefully knock a hoe, to expel the air bubbles out of the solution.The top plate and carefully leveled after first setting a tarpaulin cover (roofing material).

During the three weeks of the kiln foundations must hide from the sun and regularly moisturize.
