What's under antcaps on piers? The more one looks,the more one finds.
On top of most - but not all, there's the rub - piers, engaged or otherwise, in my 70's brick-veneer-on-sandstone-with-timber-floors house in Northern suburbs of Sydney, are pieces of what look like asphalt-impregnated material, maybe 0.5mm thick. This material is under the antcaps, and about the same size as the brick surface of the pier.
So what's it for? Additonal ant-proofing? To protect the antcap? Anybody come across this usage before?
Very curious.

You should have a dpc damp proof course,sounds like it could be bitumen impregnated aluminum?which is a form of dpc
cheersLook out if I have a tape measure in my hand.....I'm upto something
Could be either of the above: 'malthoid' or bituminised aluminium or zinc damp course. The purpose is to stop corrosion of the gal cap from moisture in the piers - the same way their is a damp proof course in the external brickwork, only in a pier simply popped on top.

Thanks gents, malthoid makes sense. I do remember it from years ago
Is this still current practice, or are galvanised ant caps regarded as sufficient nowadays?
I use poly barrier - gal ant caps have been in use >100 years

Malthoid going by the age of the house. It is to stop corrosion of the antcap from moister in the piers.Originally Posted by Compleat Amateu
It is now mandatory (BCA) to put DPC under ALL metalic materials in contact with concrete or bricks, because of moister and / or electrolytic reaction with salts or chemicals in the concrete / bricks.
