what is the correct mix for laying stone for a foundation wall (exposed) and a stone fireplace
Anonymous user 22/02/2024 - 2.34 PM
I want to build a stone and log home, in a rural area of Peru, I want to build a stone foundation and base above grade wall 3' high X 1.5' thick using volcanic and granit stones. I will build the log walls on this. what would be the correct mix for laying the stone. I have access to portland cement, sand, muratic acid to wash the stones, but burnt lime is very very hard to find, also I want to build a fireplace with a stone chimney about 24' tall by 10' at the base. again whats the mix.
Are you a tradesperson and able to answer this question?

When using mortar for stonework the mortar should always be weaker than the stone itself.
I would normally suggest 1 white cement/3 lime/6 yellow building sand.
This mix would be ok for a fireplace as well.

Period House renovation is right, the mortar should always be weaker then the stone, so a good lime mix is always a safe bet. Just keep an eye on the pointing as it is meant to sacrifice itself to preserve the stone. It is a very gradual process though, but if you experience severe weather over there that could accelerate the process.

As previously suggested the laying mortar should always be weaker than the stone! With Granite you have no problem at all, if the volcanic is igneous, also no prob...if it permeable you should really include some lime or miss it out!! 5sand:1cement should be fine. I Had a great 9 months on a similar project, digging sand from river and felling trees. Good Luck
