Our Team have recently been carrying out removal of test cores in concrete. This enables our client to determine depth & composition and can also be tested for compressive strength to determine the density of the concrete.
The removal of the cores was carried out on 9 High Rise Tower Blocks in Salford as part of the ACM Cladding replacement project.
When required, cores are cut using a drill with a hollow barrel tipped with industrial diamonds. The whole rig must be firmly fixed in position by anchor bolts to the structure. The preferred test core diameter is at least 100mm.
Concrete coring utilizes a diamond cutting drill to cut a perfect round hole in any concrete structure – in a floor, wall, or ceiling. The process is low-noise, dust-free and non-percussive, meaning it is the most popular choice for cutting.
As mentioned, concrete coring uses a drilling tool made with a diamond cutting end attached to a steel tube to pierce concrete.
Holes can be drilled at any angle – whether vertical or horizontal, using our highly trained IRATA trained Rope Access Team, we regularly carry out Core Sampling on the side of High-Rise Buildings, however our multi-disciplined Team can also use MEWPs or scaffold towers for access
We can use electric or hydraulic rigs for drilling in sensitive locations or confined spaces.
As the rig drills, we cool the cutter with water to reduce friction. When the cutting process is complete, we remove the concrete cylinder, leaving a perfect hole which can be easily repaired.
