Tip 1: How to strengthen the old foundation

During continuous operation facilities in foundation deformation may occur.This can be judged by the appearance of horizontal cracks in the facade, basement, the walls of the house.If the foundation is shrunk, it is recommended to strengthen.
Guide
1
choice of technology depends on the strengthening of the foundations of the building, its possible subsequent reconstruction, the design features of the structure and condition of the soil.In addition, the equipment is of great importance the organization performing the work.
2
Limit sealing cracks with cement mortar if they are small and shrinkage of the foundation ceased.To do this, fill in cracks and embroidered with a solution in a ratio of 1: 3.
3
If the sludge is large, try to install and eliminate the causes of its occurrence.When deformations of foundations caused by leaching of soil, resorting to technology pumping grout into the void.The foundation drilled injection well and into which is injected under high pressure solut
ion which fills the voids are impregnated and compacted soil.A layer of a special solution enhances the base of the foundation and serves as an excellent waterproofing layer.
4
If special equipment for drilling and inektsirovaniya absent, such work can be done manually.For this purpose the entire perimeter of the foundation, or in problem areas only Dig ground below the base.Dig a trench, fill it with masonry or reinforced concrete.This will ensure a tight bunch with a common array base.
5
Do not interruptions between concrete and excavation works, it can lead to devastating consequences.Such amplification is optimal at an add another floor, if the load-bearing capacity of the foundation is in doubt.
6
Strengthening the foundations of the massive buildings produced using extra bored piles.For this purpose the entire perimeter of the structure adjacent to the old foundation drilled diameter of 100 to 300 mm in a staggered every 10 cm. Then zaarmiruyte and fill them with concrete.Bored piles tie to the foundation anchors.
7
Strengthen the foundation is also possible with the help of concrete cages.Dig a trench along the belt or on the perimeter of the columnar foundations.Then, thoroughly clean the surface of the old plaster and mud.
8
Score in the design of the foundation anchors of reinforcement.Set along the foundation metal mesh, attaching it to the anchors.Then install the formwork and Grout.After curing of the concrete trench and carefully pour in layers zatrambuyte.Anchoring should be done so that the new sections of the foundation to keep the weight of the building, along with the old.

Tip 2: How to strengthen the old foundation

when repairing an old house built in the individual, particular attention should be given to the foundation.As the foundation of the whole structure, it carries a significant burden.If the home inspection revealed defects in the base of the old foundation should be strengthened.The nature and complexity of the work to restore the foundation will depend on his condition and type.
How to strengthen the old foundation
you need
  • - shovel;
  • - a sledgehammer;
  • - drill rig;
  • - building level;
  • - fittings;
  • - concrete solution;
  • - anchor bolts.
Guide
1
Inspect the foundation and determine its type.The easiest way to enhance the tape or pile foundation.Each type of structure would require a specific method to strengthen the base.For example, to strengthen the foundations of wooden buildings is preferable to lift the house and grounds to conduct a complete renovation.For brick or stone buildings, this method is not suitable.
2
Strengthening the foundations of the belt type, start with balancing action of groundwater.This will require increased footprint of the whole structure.If the house has a roll in a certain direction, it should start from that point.
3
at selected locations along the walls of the house proroyte a trench depth to the lowest point of the deformed bases located about a meter above it.The width can be equal to the width of the moat of the old foundation or be a little wider.
4
Prepare the old foundation to docking with the new.This will require to make holes for fittings.Make a new formwork for the foundation, fabricate metal frame and linked it with the valve inserted in the old foundation.
5
After connecting the old and the new foundation into one whole structure pour concrete.The solution penetrates into the holes and secure the foundations are there to grab pieces of rebar.Wait until the solution solidified.
6
Bury repaired area and go to the next segment.It is not recommended to carry out the work once around the perimeter of the house.The installation of a new foundation should be carried out in sequence, concreting sections of a length of about two meters.
7
To gain a better foundation piles strengthen it.First, the entire perimeter of the house punch hole depth of half to two meters.Set the pieces of well valves and fill them with concrete solutions.Attach the set of the pile to the construction of the structure with anchor bolts.
8
Try to keep the work as quickly as possible, avoiding lengthy downtimes and breaks.If the foundation is a long time to stand in the open form, the house will start to sink.
