There is a long list of pain points when it comes to Cold Storage and concrete. To name a few – incredibly thick slabs with rebar that conflicts with your rack installation, spalled joints, curled floors, and delamination. There have been slight improvements to concrete to combat its bad behavior and resistance to the cold environment, but no improvements would be classified as revolutionary. Until now.
There have been numerous expensive attempts to reduce joints and increase durability.
For instance, making concrete ‘expand to fight shrinkage’ has been around since the 60s; it is a difficult task to get it right, and then pour sizes and sequence is limited. Not to mention that the environment has to be just right for concrete to be placed. Others include spreading additional rock into the surface and dry shake hardeners; all in an attempt to increase durability.
Unfortunately, these old techniques come at a high cost and delamination is not uncommon.
