Over the coming weeks, access to the Norton aerodrome will be denied as the council are placing large boulders at the front of the main gates to prevent fly-tippers dumping rubbish.
The disused military base was closed in September last year after concerns were raised about the structural safety of the buildings within the perimeter.
The locks for the main gates at the site have been broken many times, making it a hotspot for illegal waste disposal.
Councillor, Karen McGowan, said: “Even if the locks are removed by the fly-tippers they won’t get vehicles onto the site to fly-tip.”
Councillor McGowan has also confirmed that the fly-tipped rubbish at the site will be removed prior to the installation of the boulders.
Requests have been made for CCTV on the site, but due to the size of the area involved, the cost of installing CCTV would not be practicable.
However, the council are instructing mobile security to monitor the site and site inspections will take place on a regular basis.
The council are also looking to speed up the demolition process for the buildings on the site, and they are currently doing the service checks to make sure utility supplies are fully isolated before the buildings are removed.
Fly-tipping of waste is a serious criminal offence and if caught, can lead to a maximum penalty of an unlimited fine or up to five years imprisonment.
