efflorescence!!!!

Postby Irishcone » Fri Dec 04, 2015 9:07 pm

Need advice. I built a 10m wall in limestone in sept and now there's white efflorescence running down 3 parts of the wall and piers! One part is really bad. First of all, is this because of me somehow or something out of my control. Its just an eye sore and thinking of pulling parts of it down at my own cost to fix it properly.

Is this a dry wall or is there some cement or lime mortar?

There is sand and cement inside the wall but not on the joints. I'm wondering was it something to do with the mix. It was a 4:1 mix of sand and cement no lime.

Have none but it's like salt deposits seeping out of the wall. If you google efflorescence on stone walls, you'll see similar.

its normally a sign of water seeping through the wall with the efflorescence being at the exit point,think how this happens on the underside of arched bridges.obviously i can't say for sure without a picture but the rain is probably making its way through the cope and has formed a mini river inside the wall try rebedding the cope wite slate in the bed

I think you may find these links useful if you fancy the read..

A poultice can be used to draw salts from the masonry, you can try a hotmix lime poultice by slaking the quicklime with aggregate and then applying hot, it will fall off after it has done its work, possibly need to reapply. My experience with this is limited but look into it.
