Expansion Cutting Sydney & NSW

At Impact Concrete Cutting, we specialise in expansion joint cutting, a critical service for maintaining the structural and aesthetic integrity of concrete slabs. Our expertise, honed over almost a decade, allows us to address the natural tendency of concrete to crack as it cures. Utilising high-quality equipment and techniques, we ensure that freshly poured concrete for foundations, paths, driveways, and concrete floors retains its intended appearance by preemptively managing potential cracking.

What Is Expansion Cutting?

Expansion cutting, or control joint cutting, is essential for managing the shrinkage and subsequent cracking that occurs in newly poured concrete as it sets and hardens. By performing expansion joint cutting during the curing process, we create predetermined lines along which the concrete can safely crack, directing these cracks away from the slab’s visible or critical areas, thus preventing trip hazards and maintaining the concrete’s appearance. These strategically placed control joints typically range from 25mm to 100mm in depth.

Our Approach to Expansion Cutting

Our team of professional concrete cutters utilises state-of-the-art equipment, including soff cut and diamond-tipped blades, for precision cutting. We initiate the cutting process within the critical 3 to 10 hour window after the concrete is poured, ensuring the slab has achieved sufficient strength. This timing helps prevent ravelling and unwanted damage, maintaining the high quality of our concrete cutting services.

When and Where to Cut

The timing of cuts is crucial for expansion cutting. Incorrect timing can lead to ravelled edges or uncontrolled cracking. Our experts, with almost a decade of experience, closely monitor the concrete’s curing process, conducting trial cuts to determine the optimal cutting window. The placement of cuts is carefully considered to align with structural and aesthetic requirements, ensuring the integrity and appearance of your concrete installations.

Techniques and Equipment

We employ wet and dry cutting techniques to suit the specific needs of each project. Wet cutting, favoured for its dust control benefits, involves the use of water to keep the blade cool and extend its lifespan. Dry cutting is utilised when water use must be minimised. Our commitment to customer service ensures that every cut is precise, controlling cracking without compromising the structural integrity of the slab.
