Stitch Drilling
Stitch drilling is a type of core drilling whereby one of our professional team members creates overlapping holes. The stitch drilling method enables us to create large openings with a series of smaller core holes, which overcomes the maximum size barrier of the diamond drill bits. Not only does it allow the creation of large holes, it's ideal for removing concrete too.

Use Cases of Stitch Drilling
Stitch drilling, also known as stitch coring or diamond stitch drilling, is a specialised technique used to create large, precise openings in concrete, masonry, and other hard materials. It involves drilling a series of closely spaced, overlapping holes to gradually remove material and form the desired opening.
This method is often used when conventional diamond drilling or cutting methods are not feasible due to the size or shape of the opening required, or where maintaining the structural integrity of a building is paramount.
Benefits of Stitch Drilling
Precise and Accurate Openings
One of the benefits is that it allows for the creation of precise, straight, and accurate openings in reinforced concrete structures. This ensures that the openings are aligned correctly for the intended purpose, such as installing beams, conduits, or pipes.
Minimised Structural Damage
Stitch drilling minimises the damage to the surrounding concrete structure compared to conventional drilling. This is because the small, closely spaced holes distribute the cutting force more evenly, reducing the stress on the concrete and preventing cracks or spalling.
Reduced Structural Weakening
Since stitch drilling creates multiple small holes rather than a single large opening, it significantly reduces the weakening effect on the structural integrity of the concrete. This is particularly important for structures with high load-bearing capacity, such as bridges, skyscrapers, or underground tunnels.
Suitable for Large-Scale Openings
Stitch drilling can be used to create large-scale openings by incrementally drilling multiple rows of closely spaced holes. This allows for the creation of openings that would be impractical or structurally challenging to achieve using traditional methods.
Versatility and Flexibility
Stitch drilling can be adapted to cut through various orientations. This means it can be performed horizontally, vertically, and on an incline. This versatility and effective method makes it suitable for a wide range of applications in both new constructions and renovations.
Reduced Noise and Dust Emissions
Stitch drilling is relatively quiet and produces minimal dust compared to dust produced by other cutting methods, such as jackhammers or explosives. This is particularly beneficial in urban environments like London, where noise pollution and dust control are important considerations.
Environmentally Friendly Approach
Stitch the drilling process utilises water-based cutting fluids, which are less harmful to the environment than oil-based fluids commonly used in other cutting methods. This eco-friendly approach aligns with London’s commitment to sustainability and environmental protection.
