Not infrequently a house newly built, the walls have cracked. Cracks were likened the injuries are on our skin. If not treated will worsen. The point here is healed cracks are covered, the walls are patched and can be seamlessly diperbaikihingga again as before. But so that we can fix it properly, then we need to know what kind of “wound” what’s hit the wall of our house, so we can take appropriate corrective measures.

According to Dr. Ing.Ir.Henki W. Ashadi (Head of Laboratory Concrete UI), cracks in the walls of the house can be divided into two types of structural cracks and non-structural cracks. Both have different characteristics, different causes and different handling.

Structural cracks

Structural cracks are cracks caused by a shift in the structure that sustains the wall. These cracks need to watch out because if allowed to continue, will impact on the robustness of the building. Characteristics were very typical, ie cracks starting from the top corner to bottom corner and form a diagonal line. But there are some cases somewhat different characteristics, namely the breakdown of the line followed the pattern of bricks.

The main cause is due to a shift in the support columns and foundation walls. When the column and the foundation shifted or down, walls that had been silent as if forced to move and are attracted to it here.

Shifting or falling of this column can be caused by two things, namely vibration and unstable soil conditions. Vibration can be caused by natural and human. Caused by nature are usually caused by earthquakes. While that is caused by humans usually occurs when there is a specific treatment of land located adjacent to buildings, such as large-scale excavation for construction of basement or foundation piles. In addition to its vibration is usually caused by a shift in the column alias saturated soil conditions that contain too much water such as swamps and clay soil. When given load, the water that meets most of the pores of the soil will be out and the soil surface will decrease. And automatically, foundations and columns that are above ground will follow down.

Improvement

For improvement, we must first fix the foundation and column shift it. Retrofitting can be done with the injection system, which gives limestone, cement, and sand around and under the foundation. After the cause was repaired, then the walls are cracked handle. There are several methods that can be done, depending on how severe the damage. Among them are membobok wall and use steples.

Membobok walls, some have argued that membobok cracked walls if there are more than 0.6 cm. but there is also the opinion should be as wide as any cracks should be handled in a way membobok wall around the cracks, then put another brick with cement. The reason is his job easier but their impact is better than using an iron walled planted.
Using steples, meaning that when the walls cracked, then you can mensteplesnya by using iron bars. Iron serves to hold the cracked brick making brick resistant to traction. The trick is unloading holes in stucco and brick around the cracks, then mix mortar and sand in the hole, and if necessary, install also the iron bars of 8 mm diameter and a length of 30 cm for every 10 layers of bricks. Reinforcement is mounted perpendicular to the fracture line. After reinforcement is installed, close the hole that was created with a mixture of mortar and sand.

Tip for you who have structural cracks in the walls that is not directly addressed if cracks appear, wait a few moments until the breakdown is completely finished. Observe the breakdown, if the cracks do not grow a few days, you just do the repair.

Non-Structural Cracks

Non-structural cracks are cracks that are rather light, which only attack the surface of the wall only. These cracks are often referred to as the “cracks” because the line is very thin and soft breakdown such as hair. Non-structural cracks are not stabilized, could be from top to bottom, from right side to left side, or may take the form of abstract irregular.

Cause

Differences expansivity material shrinkage. The wall consists of several building blocks of different. Inside there is a red brick or adobe, or brick light, as well as for species of mortar, plaster, and references. Each expansion bahanmemiliki shrinkage values ​​are also different. When there are changes in temperature, the material will shrink more quickly while other materials may not change anything. Difference between “movement” is, although invisible, can trigger a rift.
Humidity is not maintained. This relates to when the process of building a wall in the dry season, in which the walls of the dalambelum dry out completely while the outer wall directly exposed to dry due to direct sunlight. Such rapid change is what causes the outer layers of the wall “rupture”
Material composition is not quite right. Each wall material, whether it’s red brick, brick, or brick light has its own characteristics. Because it had to be a special adhesive material, so the more sticking plaster and brick. With this special adhesive, no need to make a thick plaster. Plaster is too thick, weighs more heavily and even make a quick escape and form a plaster cracks in the wall.

How to patch the cracks

Combine the water into the material adder crack (crack filler), in accordance with the specified dose. Stir well.
Cracks in walls must be scraped off first, so that the mixture can be shut down right at the source of crack
Apply this mixture along the cracks, smooth with a putty knife. After that, the walls can be repainted.

Prevent cracking from the beginning

Some precautions you can do is:

When building a house, do not there is corruption sizes and materials. Especially when working structure. If the size and material of construction minus-subtract consequently be unstable and cracks in the walls of both structural and non cracks will often occur.
Stretch of wall that is too wide also cause cracking. masonry alone is not strong enough to withstand a horizontal load. Therefore, each a distance of 3 m at the wall should be installed practically column that serves to increase the stiffness of the wall.
The composition of cement and sand will determine the quality and acian plaster walls. To avoid cracks, the use of instant cement directly mixed with water will be very helpful. Why, a mixture of cement and sand is more consistent because it is made in a factory. In addition to the standard raw materials, cement also has instant adhesive power is higher, thanks to a special ingredient that is added to the mixture.
When the installation of brick to the wall, the error is often done hastily taped immediately after the brick is installed. Give time for the water content in the species (the mortar between the bricks) has been lost, at once so that the masonry was swollen and shrunk down to a stable size. Ideally, after 2 to 3 weeks, then the wall should be plastered and the ACI.
