How to Repair Wall Cracks ?

In daily life, we often find events rift wall. There are times when home construction is still relatively new, but the cracks are there. Cracked wall is a problem that often occurs in a house which is very disturbing both in terms of beauty, and a sense of security as fears of building collapse. How could this happen and what to do to handle it? To find out how it could happen, we need to know that there are many causes of cracks in the walls of the house

Here are some of the causes of a cracked wall

Building structure (column, beam, slab, foundation) is not strong

Structures that are not in support of the load caused the couple brick walls bear the burden of the case, masonry which should only serve as a room divider should help the existing structures in maintaining the stability of the home, this is what causes a cracked brick wall as it works out his ability and the result is the most fatal building collapse.


The use of a mixture of brick masonry that is not true

For example, the use of sub-standard cement needs, the use of water that does not meet the requirements, the use of sand which contains a lot of mud or with high levels of organic matter. Mixture ratio of masonry material that is not true can cause masonry to become brittle and crack even the collapse of the building.


Any additional load on the building

additional burden here means a given load on a structure exceeds the initial planning, for example, which was planned to house one floor and the floor level to 2 in the absence of structural strengthening, natural disasters such as earthquakes, landslides, heavy winds, floods and the like. additional expenses that can not be supported by the structure can cause damaged brick masonry.

Stucco or avian drying process is too fast

drying process is too fast can cause cracks in the brick walls, prevention efforts by watering the walls plastered or of aci after finishing work in progress.



If we have not already build, we can anticipate or mitigate the risk of cracking the wall with some of the following;

    Choose the location of the land is flat, strong and not easily moved.
    Avoid building a house in the area around the slopes, hills, adjacent to the river water flow, except when you have a structure and a reliable engineer.
    Use building materials with good quality and sufficient water clean and pure.
    Keep the quality of the mortar, so that the same mixing quality in every area.
    Strengthen your building structure, foundation can increase the volume and add steel reinforcement to the structure sloop.
    Keep an eye on the construction process carefully.
    Choose a reliable development practitioners

 How to Overcome Wall Cracks
The first step you should do is look at the type of cracked :

Hairline cracks, the cracks are less than 1 mm in width and does not penetrate to the other side of the wall due to imperfections at the finishing wall, such as: plaster walls that are not watered first, the composition of which is less than perfect stucco, stucco not dry enough or quality wall paint the elasticity is less.
The solution:

    Hairline cracks that expand the section to determine the extent of cracked so when patching the cracks in the walls go up gets. Then fill it with wall filler, sandpaper after completely dry, then seal with a sealer before the wall repainted.

Overcoming cracked wall in the corner of the frame
Building problems frequently encountered in the corner of the wall cracks is jamb. Maybe for some people these cracks is considered normal, but actually there is a way to overcome the cracking wall light in the corner of the frame. As I mentioned solution is the application of tile grout.
 There are also the steps are as follows:
1. Make sure that the widening rift had stopped.
2. Take the nails and clean the car aperture.
3. Apply grout in a gap in the wall cracks, try to flush with the wall surface.
4. Clean and sandpaper to smooth the surface flatness of the wall

Structural cracks, cracks with a width of more than 2 mm and translucent on the other side of the wall. This is because:

    Reduction or shifting foundation bearing capacity due to unfavorable or less dense. This could be due to unfavorable soil conditions or it could be due to changes in soil characteristics due to natural events such as flood, or earthquake ground motion.
    Foundation size does not match the load and carried or less perfect when the implementation process.
    Damage to the column (pole) and cracked or bent beams for example, due to lack of numbers or size of primary iron and steel reinforcement binder (stirrups) and poor quality / grade of concrete used or less perfect during the process of making concrete strength against pressure is reduced.

The solution:

    To create a foundation down new foundations nearby with detecting severe cracks on the wall above it. Compact land under the new foundation and make the column / pillar to help new load distribution of slop and floor beams on it.
    For the cracked beam, if conditions permit necessary to add the column / pillar underneath so that the distribution of the load beam to be reduced. If not possible then injected beam g with epoxy that is specific chemicals that are binding and dry fast then do the size of the beam with reinforcement from the outside.
    To the column / pillar cracked, create additional fields near the crack to split the pole loading on the broken column or by strengthening the column by injecting / clicking-grouting with liquid epoxy and widen the size of the column / pillar.
    For small cracks in the columns and beams, enough with the addition of iron reinforcement plaster that does not relate to the outside air which can cause rust.

Floor rift rift floor, especially on the 2nd floor was marked by the outbreak of rift caused tiled concrete floor underneath. This could be caused by an earthquake, or the quality / grade of concrete that does not meet the standards or it could be due to a technical fault on the concrete floor during construction mistakes such as concrete steel woven structure, the position of casting the connection concrete or form work / concrete mold removed before the concrete hardens completely .
Solution:

    For the cracked concrete floor, first by removing the broken tiles then scrape cracks, injecting / clicking with liquid epoxy-grouting the cracks shut with plaster and installing ceramic back.
