RAAC Concrete issues bring asbestos problems back to the fore

RAAC concrete asbestos

The recent headlines regarding crumbling concrete in schools have recently brought concerns about a double threat with asbestos being disturbed that is still present in many schools. 

As attention is focussed on plans to remove the brittle RAAC (Reinforced Autoclaved Aerated Concrete), there are cases where asbestos surrounds the material and the work becomes a much bigger problem. 

It is highlighting the long unresolved issue of asbestos still present in many schools when it was used extensively during its most popular time in the 1950’s. 

Remediation works are estimated to slow dramatically where asbestos is present, extending the time school buildings have to remain closed.

See below for details on where asbestos can be found in homes and commercial/government owned buildings.

Common use of asbestos in residential properties

Inside an older standard dwelling built before 2000 you might find asbestos typically around he following areas:

As Insulation – so around water tanks, on pipework, as loose fill insulation, around a boiler or inside an airing cupboard.

Asbestos can also be present in a partition wall, in a fuse box or behind a fireplace. Sometimes it has been used as decorative ceiling coating, for example Artex.

Outside a property you might find asbestos around the roof – on soffits, gutters or downpipes. It is very common in the form or corrugated asbestos cement roofing on garages, and sometimes window panels.

Common use of asbestos in commercial properties

Industrial properties tend to have more asbestos use – especially where more pipework is present. Sprayed asbestos can be found on columns, beams, walls and ceilings. Also partition walls, floor and ceiling tiles and fire doors can contain asbestos.

Asbestos has also been used around toilet cisterns and seats, and also in some fire retardant textiles. You might also find it on flues.
