marshy soil exposed to seasonal fluctuations are more than everyone else.They saturated small fraction particles, and therefore often form floaters.In winter, they freeze and swell in the spring - blurred with the rise of groundwater.Put the foundation in the swamp with his own hands - a difficult task, but it is solvable.The main thing - to study the soil and to choose the right type of support and the depth of its inception.
sure to set the composition of the soil and its change at different depths, as well as determine the occurrence of jars and assess the terrain.Research can be done yourself, but it is better to engage the experts.For analysis of the content of soil will have to drill several holes at different points, or dig pits.
If the soil is not waterlogged, enough to make a drainage area to avoid reheating
In some cases, the thickness of the peat layer is small and it can be simply removed.Then it sets the foundation for a stable rock that lies below.His views take, given other technological or financial considerations.
In other cases, will have to choose from two options:
- pile foundation;
- monolithic slab.
final draft of the claim based on the construction of the structure and the total pressure on the ground.
How to Build a foundation in the swamp
device base in the swamp
pile foundation lets go flimsy layers and rely on safe ground, able to hold heavy loads.
pile foundations in the swamp
usually used for the construction of several types of piles:
- Screw metal.Not very durable, since in an acidic environment quickly oxidized iron;
- Driven.Their installation is expensive and requires the use of construction machinery, but its entrance to the site can be difficult;
- Bored.Mounted on a pre-drained soil.Creating a foundation with such piles includes a large amount of work, also is expensive.
Whatever type of support you choose, at the conclusion of the grillage is constructed on top of them.For wetlands it is in the form of reinforced concrete slabs.
monolithic slab foundation - a universal means of support in the construction of houses in marshy areas.He roads, but quite reliable.The base is obtained floating, and a large area of the foot well distributes the load on all sides.This avoids deformations of the building and its individual elements.
How to slab foundation
solid foundation in the swamp
Step №1. before filling a plate, you need to prepare the ground beneath it.The top layer is removed about a meter and poured the gravel bed, stones and sand.Sometimes it is partially replaced debris.All thoroughly moistened and compacted.This sand and gravel bedding allows groundwater to move under the sole, without stopping, and less in the winter swell.
Step №2. top cushions partitioned thin cement mix layer as a substrate.He had smooth surface gravel.For 48 hours he will dry up and then we can put a heater.Typically, this is done using slab Penoplex or styrofoam 10 cm thick.
Step №3.Top placed several rows of roll waterproofing, for example roofing material.He will not allow the soil moisture on the capillaries to soak into the concrete base.Better yet, use the polymer diffusion membrane.They not only protect the concrete from water below, but also due to vapor-permeable properties of the moisture is removed from him.
Step №4. Set formwork.Removable fence is assembled from planks held together with nails, but can be applied non-removable sheets of foam insulation that will be both.
Step №5. reinforcement for the foundation in the swamp have to choose high-strength rods with a diameter of 12-16 mm.Formed two-level mesh with a mesh size of 15x15 cm. Dressings are performed with steel wire.
Step №6. pouring concrete is performed at a time that is not formed within the joints, weakening the structure.Solidifying the mass treated vibrators to remove air from it.Finally, the surface is leveled screed.Stove will dry and gain strength for at least a month.To process was evenly ground closed with PVC film and occasionally moistened.The willingness of the foundation can be determined using the same polyethylene when condensation ceases to settle on it - the process is complete.
Step №7. The formed slab must be protected from moisture on the top and sides of the surface waterproofing.She closes the concrete from freezing and physical damage.
With a small budget to build a foundation in a swampy area is very difficult.Even on light soils and dry casting poles takes from 1/5 to 1/3 of the total cost of the house.Therefore, the type of foundation and building materials you need to decide before buying the land, and for this we need to have full information about it.
