Joint Sealing
Our joint sealing services in combination with other preventative maintenance work offer an excellent alternative, helping you to safeguard your concrete and asphalt surfaces against unwanted damage and dilapidation, extending their lifespan and reducing maintenance costs.
How concrete joint sealing is used
Joint sealing is a vital process for ensuring the longevity of concrete and asphalt surfaces. It involves the application of sealant material to expansion or contraction joints, which allows the concrete or asphalt to move through natural expansion and contraction heat cycles while maintaining a seal, preventing water and contaminate ingress into the joint and slab sub-base. Joint sealing can be done during construction, or completed on failed joints by raking out existing material, preparing the joint and then re-sealing.
We provide high-quality joint sealing services using either bitumen-based N1, N2 and 95.25 Oxidised products or Polysulphide cold pour fuel-resistant material for use where fuel or oil spills may occur. Our team of experts has the equipment and experience to tackle any sealing job, including cable chasing and sealing, with both hot and cold pour capabilities.

It involves the application of sealant material to expansion or contraction joints, which allows the concrete or asphalt to move through natural expansion and contraction heat cycles while maintaining a seal, preventing water and contaminate ingress into the joint
- Diamond Wire Sawing is a powerful and flexible technique that uses linear wire embedded with diamond beads to cut through reinforced concrete, masonry, and other hard materials. It is a fast, quiet, and effective way to cut large structures and plinths with precision, and it is especially useful on projects where deconstruction work requires careful consideration.
- Hydraulic Bursting is also known as hydraulic splitting, or hydraulic/silent demolition. Bursting is a method used to burst large volumes of concrete in a controlled methodical manner.
- Floor & Wall Chasing utilises diamond sawing equipment to create accurate and precise chases in your floors and walls for ducting, cabling or pipes keeping them safe, tidy & hidden below the surface.
