Wall Crack root causes & How to deal with it?

“Less opportunity to occur wall crack shrinkage in your project with Zmartbuild Wall Panel”

Once builders and contractors in India have to build wall and partition work, traditional brick and AAC Block are usually materials that have been selected to use. As they are well acquainted with these materials for long time and it is easy to get from the market. Because there are many producers and suppliers.

However, most developers and project managers often experience or encounter the problems on wall after completion of project, especially “the wall crack from shrinkage”.

This crack makes project owner to be nervous and anxious owing to easy to get the claim from their customers. Then they should know how to reduce the chance of having wall crack from shrinkage. Or which materials should be used in order to have less opportunity to have this type of wall crack.

Firstly, developers and project managers should grasp all types of wall crack and their root cause. In order for them to be acquainted with another materials besides clay bricks and AAC Blocks.

What are Root Causes of Wall Crack?

Wall Crack Problem Infographic by Zmartbuild

Most Developers and Project managers used to experience or face the wall crack problems. And need to know their root cause in order to analyze and find the way to solve these issues. Wall crack has many causes then the corrective ways which will be different depends on the cause of the cracking.

The cracking which will take place more or less depends on the material used for the construction, the climate, the working method during the construction. Including labor skill and the expansion and the sacking of the structure in that area.  There are three main causes of wall crack as following.

1. Chemical Reaction

Wall Crack from chemical reaction

It can cause the small cracks on interior and exterior wall, column and wet area. These cracks are caused because the water used to mix with the plastering mortar is lesser. Plastering mortar cannot ventilate the heat. When the plastering mortar becomes set, it will have the chemical reaction which causes the high heat until there are some cracks on the plastering wall.  Nevertheless, these cracks will not have the impact on the structure of the building. But it will have the effect only on the exquisite surface of the building.

If the cracks are not deep, they can be fixed by using the Putty to bond the jointing parts and painted one more time to complete the job. This type of cracking may come from the hot climate which makes the water evaporated slower than the chemical reaction in the plastering mortar which finally causes the cracks as well.

2. Bonding of the plastering wall with other materials

Cause of wall crack

The cracking comes from the expansion and the shrinkage of different material base because each material will have different ratio of bonding. Furthermore, the external wall outside the building will have the higher temperature than the internal wall. Therefore, the elasticity and shrinkage of the wall for both sides will change differently which will incur the wall crack.

These small cracks can come from the window frame or the door frame in the horizontal, vertical and diagonal direction.

3. Building structure

This type of cracking does not take place often. However, if it takes place, it is due to the piling foundation, beam and the natural collapsing. Or the natural subsiding of the ground or the soil or the moving of structure owing to natural disaster e.g. earthquake and heavy storm for instance. It will get deep inside the wall until the bricks for both sides can be seen inside.

The correction requires the specialized structural engineer to analyze and figure out the root cause. As it will have an impact on the loading capacity of the other parts of the building.

From these aforesaid causes, most of the wall crack found come from the chemical reaction, installer’s skill and the shrinkage of wall.

Comparison Wall Crack on each type of material

Let’s see the likely chance for the shrinkage crack in wall by building materials. There are three types of materials for comparison.

1. Traditional bricks:

Brick Wall in Mumbai India

Clay brick is likely and mostly to have the crack shrinkage because the body material comes from the soil, husks and ash which will be burnt together. The plastering mortar will have the thickness for each side of the bricks around 1 cm.

When plastering, hence it makes the ratio of water absorption higher as well as the smaller size of bricks bring to a result it requires more units of bricks per one side of the wall. So there will be more jointing and connecting area between panels.

It is likely that the wall will not be straightened and the wall will be fallen down easily.  Those installers must plaster wall with mortar for more thickness in order to make wall stand straight on same level. As a result, heat transfer of mortar is not good enough which can lead to the higher chance of shrinkage crack in wall.

2. AAC Blocks:

AAC Block in mumbai india

This material will have less chance to have the shrinkage crack in wall problems than the traditional clay bricks. Because the material used come from the lightweight concrete which goes through the autoclave process.

It absorb less water from the plastering mortar because such an autoclave process will accelerate the chemical reaction and the usage of water in AAC Blocks has almost completed. Therefore, it does not absorb more water from the plastering mortar than traditional clay bricks. Whereas still have some water absorption because of the small holes in AAC Blocks.

In addition, if you consider the size per unit of AAC Block with the clay bricks. Although AAC Blocks will have the bigger size per unit than the clay bricks. The installation of one side of the wall requires more units.

AAC Block makes more connecting and jointing areas which is likely that the wall will not be straightened and the wall will be fallen down. If the installer is not specialized in the installation of the wall. And needs to plaster the wall with the mortar for more thickness which is similar to the construction of traditional clay bricks. So the heat transfer of the wall is not good enough. Wall crack from shrinkage will be likely to take place also. 

3. ZMARTBUILD Wall Panel :

Has the same material as AAC Blocks but with the bigger size of the material in one piece from the ground floor until the ground ceiling above. It affects to be few connecting and jointing areas.

How to Use SCG Fiber Cement Lap Siding for the Interior Design?

“Wood is one of the interior design materials which make your house look cozy and nature-like. However, these days, we are running out of trees and wood becomes more expensive. Also, wood requires time and expenses to maintain as well. Therefore, fiber-cement lap siding is a good alternative material due to its termite-free property and durability, which can be used in the wet and damp area such as toilet.”

They also come in different textures (smooth, wood grains, and cassia texture). The lap siding can be painted over as you wish. Some models are pre pained from the factory (Mostly brownish shades). The long lasting fiber cement board lap siding used for the interior design consists of the “decorative wall panel” and “wood plank lap siding”.

Room Style, Your Style

If you seek for the natural ambiance, the SCG smartwood plank lap siding with the grain texture can be used to achieve that look. However, if you prefer the modern style, you may use the regular smooth-texture wood lap siding.

Meanwhile, the colonial style room is suitable with the lap siding which the edge is lathed.  Each SCG fiber cement sheet lap siding models may have different ways to install; some may be installed in a clapboard style; some may have the bevel to install over to hide the screw.

Apart from the decorative wall panels and lap siding,SCG fiber board cement lap siding also comes in the form of “Cornice” for crowning the top and bottom edge of the ceiling, “Lath” for ceiling installation (smooth and wood-grains texture), “Sunshade” for room partition, and “Decorative Stair wood” for stair riser, stair tread, banisters, and landing stage installation.

However, please keep in mind that “every part of the SCG Smartwood wooden stairs must be supported with the steel framing because the main purpose of these woods is to decorate only (unlike wooden stairs that are real wood)”. Also, you must strictly follow the manual once installed for your own safety.

Type of Fire Resistant Wall

Furthermore, building design and materials used decision in construction are also one of the crucial factors that could prevent fire.

Wall is the one of key important components for building. It should be fire protection for 30 to 120 minutes. The details are shown in the picture below.

Fire protection component - Fire resistance solution

The different fire resistance wall materials specify different performance criteria. There are many wall systems that could be fire protection up to 120 minutes, for instance, Brick Masonry, Light weight concrete block, Gypsum Drywall, Fiber cement drywall, Light weight panel. However, in case of fire, the most important thing is the time limit of fire resistance which can prevent structure enough to give people to escape from building.
