Our experienced and trained operatives at Empirical carry out diamond coring and concrete saw cutting using the most modern drilling equipment to ensure noise is limited and water containment/recycling can be catered to suit all site restrictions.   

• Cores to determine compressive strength of concrete – The most accurate way in which to determine the strength of in-situ concrete is to extract concrete core specimens.  Prior to coring, Empirical engineers will use Eddie current (cover meters) or Ground Penetrating Radar (GPR) to map out the reinforcement to ensure this is not damaged. Cores can then be extracted in accordance with sampling procedures detailed in BS EN 12504-1. Empirical also offer non-destructive testing which can reduce the number of extracted cores. For further details see - Re-bound Hammer.

• Investigatory Core Holes – During structural investigations core extraction can be a quick and efficient technique to confirm the make up of structural elements and calibrate non-destructive techniques. Using diamond drilling techniques alongside surveys such as GPR can often confirm structural details without the requirement for large scale excavations.   

• Stitch Drilling – This technique allows for large openings within concrete by cutting a number of holes adjacent to one another and creating an opening where required to any shape and size. 

• Scour Coring – Empirical can determine the foundation details of bridges over water and ascertain the presence of any scour.  For further details see – Scour Investigations. 

• M&E Openings – Empirical can offer solutions where new services or drainage need to pass through masonry or concrete with minimal disruption to the adjacent elements.  Prior to drilling, GPR scanning will ensure any reinforcement or existing services are avoided during the drilling process.
