Joint Sealing

Durable Joint Sealing For Airfield & Infrastructure Projects

Failed joints and cracked surfaces causing surface water ingress can result in significant damage to concrete and asphalt surfaces, where safety and durability are crucial. If left untreated, these can require full-depth repairs or replacement, a process that will be time-consuming, expensive, and disruptive to airport & infrastructure operations.

Our joint sealing services in combination with other preventative maintenance work offer an excellent alternative, helping you to safeguard your concrete and asphalt runways, aprons, and taxiways 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 to move through natural expansion and contraction 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 it.

We provide high-quality joint sealing services using either bitumen-based N1 and N2 products or polysulphide cold pour fuel-resistant material. 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.

Joint sealing has many specific uses across UK airfields:

• Providing a seal or barrier preventing water and other contaminants from entering the joint itself and the slab sub-base.
• Prolonging the life of new or existing joints and slabs, helping to extend the lifespan of your assets.
• Prevents the build-up of dirt and objects in joints, sometimes called FOD (foreign object debris)
• Joint sealing will also improve the aesthetics of both new and old concrete pavements

Just one of our case studies

Castle & Pryor completed a project at London Heathrow, sealing expansion joints on a concrete service road that forms part of an access route to one of the airport’s busy aprons. The sealant used had to meet BAA specifications and be aviation fuel resistant, while offering the flexibility to cope with the stresses and strains of adverse weather-based expansion and contraction, in addition to the weight of an aircraft parked upon it.

From jet washing, grit blasting, corking and priming, to machine placing the sealant itself, Castle & Pryor’s skilled operatives took care of the whole process resulting in a safe and durable seal.
