Concrete Cutting & Coring
Good concrete should have excellent durability in a variety of environments. However, unresolved problems are associated with its use, including design and detailing, mismatch of materials used in construction and repair, workmanship and abnormally aggressive environments. The serviceability of a concrete structure may be reduced over time by the disintegrating effects of in-service conditions such as weathering, and mechanical or chemical action involving cyclical load, wear, abrasion and chemical attack. These problems can cause significant deterioration in generation plant structures.
Methods to address these issues may involve in-site assessment of the structures using both destructive and non-destructive equipment. Concrete coring is the most effective method of defining the extent of damage to the concrete structure and in some cases, the underlying foundations.
Pell-Builder Inc. has the expertise, experience, and state-of-the-art facilities to properly assess and carry out reliable, effective concrete repair and rehabilitation.
Concrete coring may be required in order to run electrical, plumbing, cabling or other services to a specific area if it cannot be done via another route. Concrete cutting may be required for the same reasons or in order to make structural changes.
– Walls, ceiling, floors
– Crossovers for mechanical services and cabling
– Pockets for anchors and recessed lighting or fixtures
– Plumbing, electrical and HVAC installations
– Water drain holes in retaining walls
– Fireplace vents
– Plumbing and electrical lines
– Pockets for anchors and recessed lighting and fixtures
How does it work?
Core drills are used for a wide variety of applications either where the core needs to be preserved (which is rarely done in concrete coring), or where drilling can be done more rapidly since much less material needs to be removed than with a standard drill bit.
This is the reason that diamond-tipped core drills are commonly used in construction to create holes for pipes, manholes, and other large-diameter penetrations in concrete or stone.
Core Drilling attaches a diamond-tipped, drum-shaped coring tip mounted to a guiding track to create precise, plum or angled, clean, circular diameter cuts.
ADVANTAGES OF CORE DRILLING
– Clean, round, accurately sized holes
– Cored sections safely removed without dangerous dropping of spoils
– Coring in confined spaces
– Unlike rotary percussion tools, there is no vibration when core drilling and consequently, no structural damage because reinforcing rods are not loosened.
– Core Drilling is an economical, quick and clean process whose applications have greatly expanded in recent years. Special equipment enables the drilling of holes up to 48 inches in diameter.
