Cutting Up London's Heathrow Airport - Creating New Premium Parking

careys logo



London's Heathrow airport is a site of regular projects for Castle and Pryor and once again we've been commissioned by Careys PLC for our concrete cutting service to complete works to an existing area within the airport site. With refurbishment work over the next 5 years, Castle and Pryor are working closely with the 4 main contractors to assist in completing these works. In this particular case we have been contracted to cut the concrete and tarmac of the existing N2 staff car park. The project was situated on the Western Perimeter Road and the car park has been upgraded to provide a premium business car park to enable passengers' closer parking to the airport.

Chris Mack, Site Manager for Careys PLC states 'As usual Castle and Pryor have completed the work to excellent standards, as always, on time and to the brief, I'd have no hesitation in recommending them for other work and look forward to working with them on future projects'

The staff car park was re-located and the existing surface required full replacement. The materials consisted of a top surface of tarmac laid over a concrete base. One of the many key challenges to airport projects are the cables and piping which lie beneath the surface in and around the airport and its perimeter. It is essential that any work where the cutting blade or drill head penetrates the ground does not sever essential cables and piping, these are known as 'service strikes'. To avoid service strikes the main contractor commissions an x-ray or CT scan of the surface to identify cables and piping. From this 'mapping' the surface is marked-up in colour according to the type of utility beneath the surface, in addition to this they identify the depth of the cabling to define the cutting or drilling depth allowed. This information is then provided to Castle and Pryor, who then proceed according to the main contractors' marked out surface.


In this particular project we utilised a diamond floor saw methodology and concrete cutting to depths of 300mm creating chases of over 2000lm, which allowed Careys to remove the concrete and tarmac and reform the car park surface all to schedule.

At Castle & Pryor we take an extremely detailed approach to our work in any environment, our operatives are fully qualified, regularly certified and thoroughly briefed in their task briefing prior to commencing of the work. Including a service strike briefing where each operative is instructed by our qualified supervisors on the potential for service strikes and the project is then executed in a safe and professional manner.
