Here explain v method which is very helpful to repair all defects of wall. The list of all method is given below.

1. Sealing of Cracks by Epoxy Resin Injection:

The sealing of cracks is i of the all-time type of repair of brick wall defects method. In this method Sealing cracks and other brick wall defects by the help of epoxy resin injection.

Epoxy resin is a binding material with high tensile force . Due to its low fluidity it is very useful in filling small cracks, while fluids with epoxy resin, used to make full large cracks (cracks) or holes, epoxy resin with ISI mark must be used.

This method is used to seal small and medium cracks 0.v mm to 5 mm wide.

The method of sealing the cracks in the wall is equally follows.

Loose textile is removed from the outer surface and cleaned.
A plastic injection port is placed on the surface of the crack on both sides of the member. Such an injection port is sealed with an epoxy sealant. The spacing between such injection ports is kept approximately equal to the thickness of the member.
After the epoxy sealant freezes, a depression-fluidity epoxy resin is forcefully filled into a port. If at that place is a vertical crack, first filling the epoxy resin in the lowest port, and if the cleft is horizontal, beginning filling the resin in one stop port.
Continue injecting the resin until the resin starts coming out of the same port on the other side of the member or the port above information technology. So close the injection port and inject resin in another port like this.
If the crevice is pocket-sized, high pressure is required or the spacing of the role has to exist reduced so that the epoxy resin is filled in the full depth and thickness of the member.
This method is useful for all types of structural members such as beams, columns, walls, slabs. This method is useful for both masonry work and concrete.

Sealing the cracks in the cavalcade:

Remove the plaster from the surface of the cavalcade, exposing the length of the crack. Remove any loose concrete from the surface of the crevice.
Employ a 'diamond tip cutter' to make a groove about 6 to 10 mm broad along the entire length of the crack.
Make a pigsty with a altitude of 150 mm between the two centres in which the nipple can exist inserted.
Fill up the epoxy resin with a pressure pump into the hole.
Fill the 5-Groove with an epoxy mortar.

ii. Repairing Brick wall defects with Mortar:

Repairing brick wall defects with Epoxy Mortar:

Epoxy mortar is mostly used as repair material. and information technology is also used equally repair brick wall defects.

If the cracks of brick wall is wider or masonry is fully damaged (masonry have pit) and then at this situation use epoxy mortar. Epoxy mortar is prepared by mixing of epoxy resin with sand.

repairing of brick wall defects by epoxy mortar — source : gooduse

The compressive strength and tensile forcefulness of epoxy mortar are higher than cement mortar and have less elasticity.

In this method, loose fabric is removed from the surface of cracks.
The cleft or pit is cleaned thoroughly.
Drill a V-groove in the crack.
Make full the groove by pressing the epoxy mortar into the Five-Groove.
If more reinforcement is needed, place the pieces of vertical iron rod on the crack and press it with plaster.

Repairing brick wall defects with Cement Mortar:

Cement mortar is also one best blazon of repair fabric. which is widely used in repairing piece of work. cement mortar is also the best solution to repair brick wall defects.

Usually a cement: sand mortar in the ratio of one: 3 to one: 4 is used for repair, in which the aggregate maximum size is 10 mm .
Cement mortar is pneumatically applied to concrete or masonry cracks.
The method is same which is mentioned above.

3. Installing Ferro-cement Plate at Corner:

Wire mesh is used to repair brick wall defects likes cracks at the corners of walls.
First the cracks are cleaned and Thou-14 (two mm wire, mm 10 25 mm opening) is practical to the corner with wire mesh nails.
This wire mesh is fitted with a bearing of 500 to 600 mm on both sides of the crack.
Then finished this work by applying epoxy mortar or cement mortar in a higher place the wire mesh.

iv. Rebuilding Portion Of A Wall:

When the major harm occurs in masonry wall at that state of affairs, interruption the masonry wall and rebuild masonry wall from the foundation. the rebuilding of wall is too one method of repair brick wall defects.

If the entire load-bearing wall is severely damaged, the entire wall is rebuilt by supporting the upper part of the structure. The masonry is cured. Curing is done after the required plaster is done. The temporary support is so removed.

5. Stitching Method of Repairing Cracks:

Stitching method is used to repair large cracks in walls or slabs.
The various steps of this method are as follows:
To drill holes on both sides of the crack.
Hunt grooves between drilled holes.
Place U-Shape M.South steel in groove and both holes which is perpendicular to cracks.
Hall grouting with Epoxy grout or other non-shrink grout. Finishing the hole and Groove with Epoxy mortar.
