CORE DRILLING

CORE DRILLING

WHAT IS CORE DRILLING?

Core Drilling is the most effective method for creating precise circular holes in tough materials. Known for its speed and efficiency, it allows for clean cuts through reinforced concrete, stone, masonry, blockwork, and brick without causing unnecessary damage to surrounding structures.

This technique is widely used in construction, renovation, and engineering projects where accuracy and minimal disruption are essential. Whether drilling for plumbing, electrical installations, or structural modifications, core drilling delivers reliable results with maximum efficiency.

HOW DOES IT WORK?

Concrete coring uses core barrels and high-precision machines like the Hilti DD 350 to ensure accurate hole measurements and precise depth control. The diamond cutting face enhances accuracy, allowing for finer, more precise cuts.

A diamond core bit serves as a precision tool, creating clean, concise holes ranging from 25mm to over 400mm in diameter. Its non-percussive rotary action maintains structural integrity throughout the drilling process. Advanced water control systems keep the workspace dust-free, improving efficiency and safety.

As drilling progresses, water flows into the core bit, preventing dust buildup. A wet vacuum effectively manages the resulting slurry, ensuring a mess-free, clean finish. This method eliminates time-consuming cleanup, reducing costs and allowing installation projects to proceed without delays.

CORE DRILLING

Core Drilling Applications

Industries rely on Precision drilling to create precision concrete holes for electrical, plumbing, heating, sewer, and sprinkler installations. Beyond utility work, drilling plays a vital role in anchoring bolts, lifting rods, and installing load-carrying devices such as dowel bars. Engineers also use this technique for structural analysis and rock assessments, ensuring safe, efficient construction and engineering projects.

Available Core Drilling Diameters:

We specialize in drilling circular holes in concrete, brick, block, and other hard materials in the following size ranges:

  • 25mm – 50mm:
    Ideal for small conduits such as electrical cables, communication wiring, and light-duty plumbing pipes.
  • 51mm – 100mm:
    Commonly used for light to medium plumbing, fire sprinkler lines, and smaller HVAC lines.
  • 101mm – 200mm:
    Suitable for larger utility conduits, ducting, downpipes, and data trunking.
  • 201mm – 300mm:
    Perfect for main plumbing lines, heavy-duty ventilation pipes, and cable tray routing.
  • 301mm – 400mm:
    Typically used in structural penetrations, manhole openings, core testing, and major mechanical service entries.

Common Applications for Core Drilled Holes

The versatility of core drilling allows for a broad range of applications in commercial, industrial, and residential settings. Here’s how our hole sizes are commonly used:

🔌 Electrical Installations

Core drilling enables clean routing for electrical conduit and power cables through walls, floors, and ceilings without damaging structural integrity.

🚰 Plumbing and Drainage

From small supply lines to major sewer pipes, our hole sizes accommodate various plumbing installations in new builds and renovations.

💨 HVAC and Ventilation

Precision core holes are crucial for ducting air conditioning systems, exhaust fans, and fresh air inlets through concrete walls or slabs.

🧱 Structural Reinforcement and Retrofitting

Larger holes (up to 400mm) are often used for installing steel columns, dowels, or concrete reinforcement in retrofitting projects.

🧪 Core Sampling and Testing

In geotechnical or structural testing, core holes provide clean material samples from concrete or masonry for lab analysis.

💡 Fire Protection and Sprinkler Systems

Clean and accurately placed holes are necessary for routing fire suppression piping without compromising fire-rated barriers.

CORE DRILLING

Concrete coring is a powerful solution for installing drainage systems in boundary walls, garages, and concrete roofs, preventing flooding and water damage. This precise technique also enables the seamless installation of windows, air purifier vents, and other fixtures, ensuring structural integrity.

By integrating concrete coring into drainage systems, homeowners can safeguard their property from water-related damage and mold growth. Whether installing a new drain in flood-prone areas or adding a sink in a basement or garage, concrete coring delivers precision, versatility, and efficiency for every project.

STITCH CORE DRILLING

CORE DRILLING

Stitch Drilling is a highly effective technique for creating large holes and slots in walls and floors, particularly in areas with restricted access. This method involves Diamond Stitch Drilling, which achieves precise openings by drilling a sequence of overlapping core holes.

When conventional drilling methods do not yield the desired results, stitch drilling provides a flexible alternative. By strategically overlapping core holes, it allows for the formation of holes of any size or shape, offering unmatched versatility in structural modifications.

BENEFITS OF STITCH CORE DRILLING?

A

Ability to drill in smaller spaces.

A

The ability to cut any shape, depth or size.

A

The general cleanliness of the work space.

A

Eliminate waste and cutting by-products.

CONCRETE CUTTING OR FLOOR SAWING

Cutting concrete

Floor sawing is a fast and precise technique used to modify flat structures such as concrete floors, roadways, bridges, and suspended slabs, with cutting depths of up to 500mm. On roadways, floor saws efficiently cut asphalt and concrete, allowing for swift repairs and modifications while maintaining clean, straight edges.

This method is ideal for cutting through reinforced concrete, pre-cast concrete, and other structural materials when level and flat surfaces require modification. Floor sawing plays a crucial role in creating expansion joints, openings for ducts, elevators, stairwells, machine pads, conduit trenches, and controlled demolition. It is widely used across applications such as floors, rooftops, bridge decks, and suspended slabs, ensuring a smooth, precise finish that simplifies subsequent paving and pouring.”

 

CONTROLLED DEMOLITION

Cutting concrete

What is Controlled Demolition?

Controlled demolition is a precise and systematic method of deconstructing structures to achieve specific project goals while maintaining strict safety standards. This approach minimizes disruption to surrounding buildings and the environment, ensuring an organized and efficient process. Often confused with large-scale demolitions involving explosives and heavy machinery, controlled demolition instead focuses on carefully dismantling sections of a building with precision and strategy.

Safety remains the top priority, as sections are dismantled in a timed manner, preventing unintended damage to nearby structures. Additionally, dust and debris are effectively managed to maintain a clean and controlled workspace. At Vus Core Drilling, we employ advanced equipment to ensure optimal precision in every controlled demolition project.
