Welcome to the official blog of Arise and Shine Constructions, proudly recognized as the top builders in Thoothukudi. Today, we are addressing a common yet critical issue faced by many new homeowners – Wall Cracks In New Buildings. As leading builders in Tuticorin, we believe it’s essential to understand the causes of these cracks, how to prevent them, and what steps to take if they occur.

Understanding Wall Cracks in New Buildings

Wall cracks in new constructions can be alarming. However, not all cracks indicate severe structural problems. Understanding the causes of wall cracks is the first step toward addressing them effectively.

Types of Wall Cracks

1. Hairline Cracks

Description: These are very thin cracks, typically less than 1mm in width.

Impact: Usually cosmetic and not structurally significant.


2. Vertical Cracks

Description: Cracks that run vertically up and down the wall.

Impact: Depending on the width and length, these can be either cosmetic or indicate more serious foundation issues.


3. Horizontal Cracks

Description: Cracks that run horizontally across the wall.

Impact: Can indicate serious structural issues, especially if found in foundation walls.


4. Diagonal Cracks

Description: Cracks that run diagonally at various angles.

Impact: Can indicate structural issues depending on their size and location.


5. Stair-Step Cracks

Description: Cracks that follow the mortar joints in a stair-step pattern, often seen in brick or block walls.

Impact: Can be a sign of significant structural movement and may need professional assessment.


6. Shrinkage Cracks

Description: Typically found in concrete and plaster, these are cracks that occur as the material dries and shrinks.

Impact: Generally not a structural concern, but can affect the aesthetics and may allow moisture ingress if left untreated.


7. Settlement Cracks

Description: Cracks that occur due to the building settling into its foundation unevenly.

Impact: Depending on severity, they can range from cosmetic to indicative of significant foundation issues.


8. Expansion Cracks

Description: Cracks that appear due to the expansion and contraction of building materials.

Impact: These cracks are entirely normal. Often minor, but can become more significant if not addressed over time.


9. Structural Cracks

Description: Cracks that indicate serious issues with the building’s structural integrity. This can be attributed to the natural movement of the building due to temperature or humidity changes. 

Impact: These require immediate professional assessment and repair to ensure the safety of the building.


10. Non-Structural Cracks

Description: Cracks that do not affect the building’s structural integrity.

Impact: Mainly cosmetic, but should be monitored and repaired to prevent further issues.


Understanding these types of wall cracks can help homeowners and builders like Arise and Shine Constructions, the top builders in Thoothukudi, to diagnose and address issues effectively, ensuring the longevity and safety of new buildings.

Common Causes of Wall Cracks

1. Foundation Issues: The most serious cracks usually stem from problems with the building’s foundation. If the foundation settles unevenly, it can cause significant stress on the walls, leading to cracks.

2. Moisture and Water Damage: Water infiltration due to poor waterproofing or drainage issues can weaken the wall material, causing cracks over time.

3. Thermal Expansion and Contraction: Temperature fluctuations can cause building materials to expand and contract. Over time, this can result in small cracks, especially in plaster and drywalls.

4. Poor Construction Practices: Use of substandard materials, inadequate curing of concrete or improper load distribution can all contribute to the formation of cracks.

5. Natural Settling: All buildings settle over time, but excessive settling in a short period can cause cracks in walls. This is often seen in new constructions as the building adjusts to its load.

6. Cement Ratio: There is a common myth in our society about construction. Many people think that adding more cement to the mix will make a building stronger. However, this isn’t true. It’s important to stick to the correct ratio of sand, cement, and water. Using too much cement can actually cause walls to crack, sometimes even before the house is finished and handed over to the owner.

Do’s and Don’ts for Preventing Wall Cracks

To maintain the integrity of your building, here are some do’s and don’ts that homeowners and builders should follow:


  • Ensure Proper Foundation Work: Always start with a strong foundation. Engage the top builders in Thoothukudi like us to ensure that your foundation is laid correctly.

  • Implement Proper Waterproofing: Ensure that your building has effective waterproofing systems in place to prevent moisture infiltration.
  • Regular Maintenance: Conduct regular maintenance checks to identify and address potential issues early.
  • Allow Proper Curing Time: Give adequate time for concrete and other materials to cure before applying any loads.

  • Delay Waterproofing: Do not delay waterproofing treatments, especially in areas prone to heavy rainfall.
