Removal of heavy duty industrial pipework containing asbestos insulation lagging

Ongoing licensed Asbestos removal project removing heavy duty industrial pipework containing asbestos insulation lagging to the internal areas of former engineering factory, Davy Markham in Sheffield. This is a large project with multiple phases and site teams present.

Our team have been on site since January 2020 and we have already completed some small areas of asbestos removal, as well as environmental cleans to areas to remove any potentially contaminated materials and pigeon guano.

The former boiler room of the factory has had all asbestos debris and residues removed, and works are now well underway of removing the industrial pipework. The pipes are at a high level, so we have worked alongside a licensed scaffolding company, Trident Scaffolding Ltd, and all asbestos enclosures are built upon this scaffolding for suitable access.

Our team on site are working on multiple stages at once, with enclosures split into roughly 50 linear metre sizes. Part of our team will be preparing the next stage whilst the current one is live, this is ensuring smooth running of our operation and completing this project in a timely manner.

Removing pipe work with asbestos lagging

Asbestos operatives work inside the enclosure to ensure the removal of the pipework with asbestos lagging is fully controlled and secure. To remove the large industrial pipes, we must use the injection method. This is where strings of needles are used with an injection machine to wet down the materials in regular intervals down the pipework, which in turn means that the release of asbestos fibres into the air is prevented as they are sufficiently dampened. The pipes are then cut in to small, manageable sections and double bagged into red asbestos waste sacks, and disposed of as hazardous asbestos waste.

The works we have been doing are currently on Bay 5 & Bay 6 of the factory, which can be seen on the far right of the building.

Frequently Asked Questions

Some of the most common questions we get asked are answered below for you! For further information give us a...

Q: What should I do if I find asbestos?

Before removals can take place, the type of asbestos needs to be identified with an independent surveyor to determine the exact properties. Never attempt to remove it yourself, and call a professional such as ourselves. If it is in bad condition it may be treated as an urgent matter.

Q: How will the quote be compiled for asbestos removal?

As each case is unique to the next, our dedicated Contracts Managers take into consideration lots of factors and this will be decided upon an initial phone call and a site visit. They gather as much information as possible and price accordingly and will give you an appropriate timescale for the works with this quote.

Q: Where can asbestos be found?

Asbestos can be found in many places. Any buildings pre 1999 could potentially have asbestos containing materials (ACM's) present. For a full list of potential places, head over to our blog.
