Joint Sealing
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.

Vac-Ex Excavation
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.

Thin Bond Concrete Patch Repair
For Facilities and Companies, concrete hard standings, roads, car parks, workshops, storage areas and any other concrete surfaces are essential assets that are relied upon. But these assets are not immune to the damaging effects that wear and tear can cause. Cracks, potholes and failed joints can quickly develop into serious hazards that compromise safety and efficiency. If these are left unaddressed, these issues can even lead to complete surface failure, potentially requiring expensive full-depth repairs or total bay replacement.
Ironwork Reinstatement
Repairs to road ironworks are a costly and time-wasting drain on authorities, not to mention inconvenient to road users. But IKO Pacopatch offers a practical, one-time solution. Designed to reinstate failing surfaces surrounding manholes, drainage gullies and other public utilities ironworks, it uses two state-of-the-art materials, the IKO Pacopatch Brick and the IKO Pacopatch Grout, which work hand in hand to create an impermeable system made to last.
Firstly, a layer of grout is installed and then the blocks introduced with more grout to fill the voids to the top of the blocks. Dependant on the depth of the repair more layers of grout and blocks are added and then a final layer of grout with bitumen coated stones introduced and pushed into the grout to provide a high grip and wearing surface.
The blocks not only provide strength to the repair but they also absorb the heat from the grout allowing for the quick return to service. And it gets better, because this is a compaction free solution - no roller or plate compactor is required, so no damage is done to the existing ironwork. Overall the process is quick and easy to do, providing a quick return to service within 1-2 hours.

Shot Blasting
Shot Blasting is an efficient and dust free method of removing coatings and preparing surfaces. The machines used are either 415v 3-phase or 110v powered and come in various sizes dependent on the project requirements. In this technique small balls of ‘shot’ are thrown at high speed at the surface removing some of the top layer of material and leaving a textured finish.
The shot blasting machines use a captivated system and utilizes dust collection and vacuum technology so that no dust or surface contamination becomes airborne. All debris are captured within the vacuum unit attached to the blaster, leaving the operation clean and dust free. Shot blasting is an ideal method for cleaning, stripping and preparing the surface of floors.

Concrete Chasing
This service is where we use the precision technology of diamond cutting to create channels in your floors and walls. These are made for cabling or pipes to run through − keeping them safe, tidy and out of sight.
Safe Percussive Drilling
Percussion drilling is perfect for projects that require a quick turnaround and strong, rough-sided holes. For example, anchoring steel-framed structures into the ground or joining concrete slabs together with steel starter bars. Favoured in the construction industry because it’s quick and cost-effective, until now, percussion drilling has come at a price.
Exposure to high levels of vibration has caused irreversible nerve-damage known as Hand Arm Vibration Syndrome (HAVS) or ‘white finger’ and Carpal Tunnel Syndrome (CTS), to thousands of employees across industries. With Sindrilla’s simple, hands-free design can safely place a single operative to carry-out percussion drilling on your site all day long - with no adverse effects.
