INDUSTRIAL concrete floors are essential for South Africa’s industrial growth but also poses more problems for the construction industry than most other concrete projects, says John Roxburgh, senior lecturer at The Concrete Institute’s School of Concrete Technology.

Roxburgh says without a well-designed, fit-for-purpose and low maintenance concrete industrial floor, factories, warehouses, storage and retail areas or other hard standing areas cannot operate at optimum efficiency.  He believes the importance of a sound concrete industrial floor is often overlooked but should be the main priority for minimising long-term operational costs.

“Industrial floors on the ground typically appear simple in their design and construction but in reality they can become nightmares for the unskilled. The Concrete Institute can testify to that because when it comes to the various concrete elements in a building, the industrial floor is by far the most problematic in meeting specifications and performance requirements, and attracts the highest volumes of calls for advice and help to TCI.”

Although a concrete floor is constructed on the ground – with minimal reinforcement – it is required to possess stringent and diverse qualities, including:

  • The correct thickness.
  • Level, flat and at the right height construction.
  • Hard-wearing dust free surface.
  • Capacity to carry large imposed loads over its entire surface – including across its joints and at its corners and sides.
  • To be aesthetically pleasing with minimal surface defects and cracking.

“The concrete used for the industrial floors needs certain plastic and hardened properties to perform and so the mix designs for these concretes are more constrained and require greater attention to detail.   Concrete floors are also often constructed under adverse conditions.  The large surface to volume ratio of a floor makes its construction very vulnerable to hot, windy and dry conditions.

“The most common problems in industrial floors are cracking, joint failure, curling, dusting, scaling, surface wear, sealant failure and excessive lateral movement of forklifts and pallet jacks.

An underperforming floor will result in slowing down of forklifts, pallet jacks and reach trucks. This causes maintenance costs on all packing, stacking and lifting machinery to soar along with more frequent and costly repairs of the floor resulting in more downtime and the need for spare machinery – all resulting in a less efficient operation,” Roxburgh contends.

“The good news is that good floors can be constructed.  To help educate those involved with concrete floors, The Concrete Institute offers a one day course, ‘Industrial floors on the ground’ lectured by MD Bryan Perrie, an internationally recognised expert on concrete floors, in which all the design principles and concrete practice needed to produce a good floor are covered. The course also includes floor repair and maintenance.   All engineers, contractors, concrete specialists, floor coating applicators, managers of warehouses and clients involved with industrial floor will benefit greatly by attending the course which is planned for Midrand, Cape Town and Durban later this year,” Roxburgh adds.
