Trusted partners in the house building sector

Our percussive rock drilling services offer a fast, precise, dust-free and cost-effective solution for airfields across the UK, with no vibrations or HAVS risk.

Percussive rock drilling is a technique that involves the use of specialised equipment to form cost-effective holes into concrete slabs and walls. We offer a range of drilling services for the aviation industry, including dowel bar drilling, induction line drilling, anchor hole drilling, and drilling holes to facilitate bursting operations.

Our selection of horizontal, vertical, and machine-mounted drilling rigs, ensures that we can tackle any job, quickly drilling holes between 16mm and 55mm in diameter.

Excavating around live utilities and vital services on a construction project can be a challenging and potentially hazardous task, with traditional excavation methods potentially resulting in serious damage to infrastructure. In the case of a service strike, this could cause massive and costly disruption to a project. However, with the use of vacuum excavation technology, Castle & Pryor is able to provide a safe and efficient solution, perfect for smaller or hazardous areas.

How we utilise Vac-Ex machines in Construction
Vac-Ex is a non-intrusive method of excavation that uses compressed air to loosen up the ground, followed by suction to remove the loose material. A Vac-Ex machine can generate a powerful stream of air with an operator controlling the intake nozzle, providing full control of the excavation while they remain at a safe distance. This method significantly reduces spoil and dust because all of the extracted material is sucked directly into sealed collection chambers on the machine, making it particularly suitable for use in confined spaces.

Failed joints and cracked surfaces causing surface water ingress can result in significant damage to concrete and asphalt surfaces, especially on areas such as Airfields, Highways and other concrete pavement areas 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 operations.
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.
