How to repair brick wall defects.
Here explain 5 method which is very helpful to repair all defects of wall. The list of all method is given below.
- Sealing of cracks by epoxy resin injection
- Repairing brickwork with epoxy mortar
- Installing ferrocement plate at the corner
- Rebuilding portion of a wall
- Stitching method of repairing cracks.
i. Sealing of Cracks by Epoxy Resin Injection:
The sealing of cracks is one 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 strength . 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 pocket-size and medium cracks 0.5 mm to 5 mm wide.
The method of sealing the cracks in the wall is equally follows.
- Loose material is removed from the outer surface and cleaned.
- A plastic injection port is placed on the surface of the scissure on both sides of the member. Such an injection port is sealed with an epoxy sealant. The spacing betwixt such injection ports is kept approximately equal to the thickness of the member.
- After the epoxy sealant freezes, a low-fluidity epoxy resin is forcefully filled into a port. If there is a vertical crack, get-go filling the epoxy resin in the everyman port, and if the cleft is horizontal, starting time filling the resin in ane end port.
- Go on injecting the resin until the resin starts coming out of the aforementioned port on the other side of the member or the port above information technology. And so close the injection port and inject resin in another port like this.
- If the cleft is small, high pressure is required or the spacing of the part has to exist reduced and then 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 piece of work and concrete.
Sealing the cracks in the column:
- Remove the plaster from the surface of the column, exposing the length of the crack. Remove whatever loose concrete from the surface of the scissure.
- Use a 'diamond tip cutter' to make a groove near 6 to 10 mm wide along the entire length of the cleft.
- Brand a hole with a altitude of 150 mm between the ii centres in which the nipple can exist inserted.
- Fill the epoxy resin with a pressure pump into the hole.
- Make full the V-Groove with an epoxy mortar.

2. Repairing Brick wall defects with Mortar:
Repairing brick wall defects with Epoxy Mortar:
Epoxy mortar is mostly used as repair material. and it is as well used as repair brick wall defects.
If the cracks of brick wall is wider or masonry is fully damaged (masonry take pit) so at this situation utilise epoxy mortar. Epoxy mortar is prepared past mixing of epoxy resin with sand.
The compressive strength and tensile force 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 crack or pit is cleaned thoroughly.
- Drill a V-groove in the crack.
- Fill the groove by pressing the epoxy mortar into the V-Groove.
- If more reinforcement is needed, place the pieces of vertical iron rod on the crack and press information technology with plaster.

Repairing brick wall defects with Cement Mortar:
Cement mortar is also one best type of repair textile. which is widely used in repairing work. cement mortar is as well the best solution to repair brick wall defects.
- Usually a cement: sand mortar in the ratio of ane: 3 to 1: 4 is used for repair, in which the aggregate maximum size is x mm .
- Cement mortar is pneumatically practical 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.
- Beginning the cracks are cleaned and G-xiv (ii mm wire, mm ten 25 mm opening) is applied 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 cleft.
- Then finished this work by applying epoxy mortar or cement mortar above the wire mesh.

four. Rebuilding Portion Of A Wall:
When the major damage occurs in masonry wall at that situation, suspension the masonry wall and rebuild masonry wall from the foundation. the rebuilding of wall is also one method of repair brick wall defects.
If the entire load-bearing wall is severely damaged, the entire wall is rebuilt past supporting the upper part of the structure. The masonry is cured. Curing is done subsequently the required plaster is washed. The temporary back up is then 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 every bit follows:
- To drill holes on both sides of the scissure.
- Chase grooves between drilled holes.
- Place U-Shape One thousand.S steel in groove and both holes which is perpendicular to cracks.
- Hall grouting with Epoxy grout or other non-shrink grout. Finishing the pigsty and Groove with Epoxy mortar.
