Concrete has many benefits to contractors, end users, tenants and building owners. The downside to concrete is the fact that it cracks and you need someone to carry out expert conrete repairs. We at the Nationwide Diamond Group have vast experience both laying concrete floor slabs and repairing existing slabs. This particular project in County Durham involved a suspended mezzanine concrete floor within an office type building. Due to many reasons concrete suspended on mezzanine floor slabs behaves differently to a typical ground bearing slab.
We often see a lot of small shrinkage cracks occurring across the beam supports even before the slabs have been loaded, and also due to numerous shrinkage restraints caused by the profile of the metal decking. Also to take into consideration is the lack of induced stress relief joints created by the design of the composite structure. This means the concrete has to crack in order for the design to properly work.
Taking all of the above into consideration Nationwide Diamond Group used their standard methodology to repair these cracks on the mezzanine floor slab in Durham. Materials were carefully chosen dependent upon the type and width of the cracks to cater for trafficking and slab movement etc.
