one. Sealing of Cracks by Epoxy Resin Injection:

The sealing of cracks is i of the best 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-scale cracks, while fluids with epoxy resin, used to make full big cracks (cracks) or holes, epoxy resin with ISI marker must be used.

This method is used to seal minor and medium cracks 0.5 mm to 5 mm wide.

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

Loose cloth 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 fellow member.
After the epoxy sealant freezes, a depression-fluidity epoxy resin is forcefully filled into a port. If there is a vertical crack, start filling the epoxy resin in the lowest port, and if the crack is horizontal, starting time filling the resin in ane end port.
Continue injecting the resin until the resin starts coming out of the aforementioned port on the other side of the member or the port higher up it. And so shut the injection port and inject resin in another port like this.
If the crack is pocket-sized, high pressure level is required or the spacing of the part has to be 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 every bit 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 crevice. Remove any loose concrete from the surface of the crack.
Use a 'diamond tip cutter' to make a groove about half-dozen to 10 mm wide along the unabridged length of the crack.
Make a pigsty with a altitude of 150 mm betwixt the two centres in which the nipple can exist inserted.
Fill the epoxy resin with a pressure pump into the pigsty.
Fill the V-Groove with an epoxy mortar.

2. Repairing Brick wall defects with Mortar:

Repairing brick wall defects with Epoxy Mortar:

Epoxy mortar is by and large used as repair material. and it is as well used as repair brick wall defectsouthward.

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

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

In this method, loose material is removed from the surface of cracks.
The crack or pit is cleaned thoroughly.
Drill a 5-groove in the fissure.
Fill the groove by pressing the epoxy mortar into the V-Groove.
If more reinforcement is needed, identify the pieces of vertical iron rod on the cleft and press it with plaster.

Repairing brick wall defects with Cement Mortar:

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

Unremarkably a cement: sand mortar in the ratio of 1: 3 to ane: 4 is used for repair, in which the aggregate maximum size is 10 mm .
Cement mortar is pneumatically applied to physical or masonry cracks.
The method is aforementioned 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 Grand-fourteen (2 mm wire, mm x 25 mm opening) is practical to the corner with wire mesh nails.
This wire mesh is fitted with a begetting of 500 to 600 mm on both sides of the crack.
Then finished this work by applying epoxy mortar or cement mortar above the wire mesh.

4. Rebuilding Portion Of A Wall:

When the major damage occurs in masonry wall at that state of affairs, pause 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-begetting wall is severely damaged, the entire wall is rebuilt by supporting the upper role of the construction. The masonry is cured. Curing is done after the required plaster is done. The temporary support is and then removed.

5. Stitching Method of Repairing Cracks:

Stitching method is used to repair big cracks in walls or slabs.
The various steps of this method are as follows:
To drill holes on both sides of the crevice.
Chase grooves between drilled holes.
Place U-Shape M.S 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.
