Joint sealing and airfield works specialists

Concrete joints are essential elements in any structure, providing flexibility and accommodating the natural expansion and contraction of concrete due to temperature changes and settling. However, over time, these joints can deteriorate, leading to issues such as water infiltration, spalling, and structural damage. That's where concrete joint sealing and repairs come in.

Cut & Core offers specialised joint sealing, repair and rectification to restore the integrity and longevity of your concrete surfaces.


Whether it's airport runways or other airfield applications, commercial buildings, or residential properties, we're here to ensure your concrete structures remain durable and resilient for years to come.

Joint Sealing & Repairs

Cut and Core concrete joint sealing and rectification

Preserve and enhance the longevity of your concrete structures with our specialised concrete joint maintenance, rectification and repairs.

​Joint sealing is essential for preserving the concrete's appearance and ensuring its long-term safety.

Debris accumulation in joints, combined with traffic, weather, and temperature fluctuations, leads to concrete damage. Neglecting these issues results in more expensive repairs, as unsealed joints allow water ingress, undermining the concrete's structural integrity. Beyond aesthetics, this damage poses safety risks that should not be underestimated.​

Cut and Core can assist with many different types of joint rectification, resulting in lowered risk and better concrete longevity. We have experience doing this work on international airports, Defence airfields, distribution facilities, wharves, multi-story carparks, and more, our expertise is grounded in practical experience.
