Superb technical and project management skills ensured BriggsAmasco delivered a safe, durable, waterproof town centre car park with minimal disruption to nearby shops and customers.

The UK’s largest roofing company, BriggsAmasco was selected by main contractors, Midas Group, to apply its high-levels of workmanship in order to provide a durable, watertight surface for a three-storey, roof-top car park in Solihull, near Birmingham.

For the car park’s surface, 3,500m2 of mastic asphalt was laid by BriggsAmasco’s City and Guild-trained installers onto the car park’s concrete decks. Up to 54-tonnes of asphalt was being utilised per day on machine-laid areas of roof, which required expert project management to ensure a steady supply of material was maintained. During one particularly complex operation, contractors were required to close sections of the car park in order to crane ready-to-apply tanks of mastic asphalt onto the roof. This required coordinated planning with the client and local authorities to minimise the public health and safety risk.

Mastic Asphalt not only offers a superbly-effective durable, waterproof surface for areas of heavy traffic, it succeeds in terms of environmental performance. Mastic Asphalt is a recyclable, carbon-zero system which offers a 100% CO2 neutral solution. It requires a high level of skill to ensure it is installed completely flat and to a constant thickness which allows for a perfect overlay of materials such as – in the Solihull project’s instance – asphalt paving. As a building has to move within a design criteria, accuracy was also paramount during the installation and supply of Radflex waterproof structural movement joints within the asphalt. To enshrine the built-up system’s watertight credentials, a layer of Jablite FR1 300 insulation was applied to the entire car park deck which was overlaid by BriggsAmasco using a lightweight concrete.

As the roof installation took place during winter months, contractors faced inclement conditions which put a temporary halt to the works programme. Asphalt requires a dry environment for it to be laid correctly, therefore cold weather also hampers its application. This challenge was overcome due to excellent project management between BriggsAmasco and Midas Group. Adequate time had been built-in to the project which enabled additional tasks and bad weather issues to be absorbed within the scheduled programme.

The project was completed in November 2016 to the client’s strict deadline and full satisfaction.

This project was a finalist at the British Parking Awards. Further details can be found here.
