Marley garage roof - Asbestos ?

Marley garage roof - Asbestos ?

Any 'more mature' builders out there ?

I am just about to take a Marley 'medium' garage apart. (Design number 862247), as it has been damaged by vandals.

The roof consists of corrugated panels, approx 6' x 4, which look like concrete, however because the garage is early 70s,I am suspicious there may be a layer of asbestos within them.

Marley disappeared from the construction scene years ago, and I cannot findanything useful on the internet, the council have advised I get in touch with a specialist, however the only one that has replied is in Oxford and is asking for a sample for analysis.

Before I break off a part, does anyone have knowledge/experience of this type of garage, and whether there is a difinitive yes or no to the construction ?

Thanks

I've got a similar roof on my garage, not Marley though. I replaced a cracked panel with one from a neighbour's garage being dismantled years ago (before H&S concerns). As the asbestos is embedded in cement, it should be safe to remove, but if you do any hole drilling (as I did) then wear a mask. Unfortunately this didn't stop a piece of fibre catching me in the eye, necessitating a trip the hospital for removal

Could be worth asking on diynot.com

My experience is similar to Llews and my local tip would only take the panels if they were sealed inside giant polythylene bags and left in a special area but that was 20 years ago so the regulations may be different now.

It is more than likely that there is asbestos built in as it was the fibre that gave the panels their strength. In the 70's there were allsorts of asbestos material available. I remember a rawlplug product which was asbestos fibre and powdered PVA which you mixed with water then inserted into a hole drilled in the wall, you then screwed in your wood screw which would never ever come out again.

So care needs to be taken mask safety glasses etc.

The 'Asbestos' sheets do not have a 'layer' in them as such.

They are 'asbestos reinforced cement sheets', there is about 6% asbestos fibre evenly distributed throughout the structure. A couple of reasons for using asbestos is it's great tensile strength and the strong bond that it develops with the cement. It also has very good filtering properties which helped with the manufacturing process.

Rarely mentioned but I think most beer was filtered through asbestos filters at one time.

Nope, still got two of everything I should have - mostly working, although some of them a little worse for wear now

I will now wear some protective clothing to dismantle the garage.

Curiously enough even the guttering appears to be made of the same material.

Although I'm not really old enough to worry about it, that is quite a worry...

As prev., one big advantage of asbestos is it's affinity to cement, individual fibres, which are very small dia. and thus cause problems by being breathable, do not readily disasociate from the cement. Any type of dust can be a hazard. I know you use a mask when drilling fixing holes

Guttering and the associated fittings, especially the larger sizes, were big business, and also side cladding on industrial buildings.

Pressure pipes were very big business, and were manufactured up to about 18" dia. being used for drinking water , sewage, gas, cooling water on power stations etc.

Water storage cisterns were also manufactured in various sizes, an offshoot of this being garden planters up to about 5' dia. in a variety of shapes, clover leaf etc.
