How to Avoid Cracks in Industrial Floors?

What are the cracks in industrial floors?

Cracks are linear separations in the floor. The size and depth of the cracks vary. They could be small, like hairlines, or deep, which indicates structural issues. The issue of cracks in the floor makes it essential for the structural consultants to give a proper design for the floor.

Factors that cause cracks:

Multiple issues result in cracks in the floor. However, the most common are as follows:

1. Cracks due to issues in the foundation:
   1. Cracks may develop as a result of unequal settlement or unstable soil.
   2. Expansive soil may cause lateral movements and, subsequently, cracks
2. Cracks due to issues in concrete:
   1. Cracking is a result of uneven or rapid drying
   2. Temperature swings result in concrete expansion, and thus, cracks
   3. Improperly compacted subgrade also contributes to cracks
   4. Cracks are also a result of impact, i.e., the dropping of heavy objects
   5. Water leaks and moisture accumulation may cause cracks.
      
      

How do cracks impact the industry?

Cracks result from many factors. It could compromise the structural integrity.

Cracks are unsightly and eyesore.

Cracks also affect the production.

How to mitigate cracks:

• The structural consultants must ensure that the subgrade is designed to suit the project requirements. The PMC must ensure proper compaction of the subgrade.
• A proper high-performance concrete mix with a low water-cement ratio helps reduce cracks. Admixtures lessen the need for water and improve concrete workability.
• Placing control joints at strategic locations helps reduce uncontrolled cracks. Moreover, spacing and depth are also essential.
• Curing is a must to avoid cracks in flooring. Ponding helps create a moist environment.
• Steel or fibre-reinforced improves tensile strength and results in fewer cracks.
• Proper design of the floor based on the load helps minimise cracks.
• The application of surface sealant helps prevent moisture ingress. However, resealing may be needed.

Structural design consultants must design the floor to suit the project requirements and thus minimise floor cracks.
