Craftsman Concrete Floors
Texas Concrete Polishing
At Craftsman Concrete Floors, we specialize in installing polished concrete floors in luxury residential renovations. As more and more industrial buildings are converted into luxury condos, one of the most common questions we’re asked is ‘can an old concrete slab be polished?’. While old slabs are much more challenging than modern pours, the answer is always nearly yes.
Why are old slabs more difficult to polish?
One of the main reasons older slabs are difficult to polish are the techniques used to pour the concrete. Modern concrete is leveled using large ride on concrete leveling machines called power trowels. These machines can be eight feet or more in width and can quickly flatten large areas of concrete. Older concrete pours are more likely to have been leveled by hand, leaving inconsistencies in depth of the concrete.
High Rise Floors
In modern high rise construction, concrete is brought onsite in trucks and pumped from the ground to the floor being poured. This allows for very fast and homogeneous concrete pours.. In older high rise construction concrete was poured from trucks into buckets and then raised by a crane to the floor being poured. This technique meant there would be a significant amount of variation between different areas on a single floor.
