Hi, I'm a novice building a small natural stone (Cotswold) wall with recessed seating – c. 4m long wall, double skin.
I have about 200 stones, various shapes, sizes.
My plan is to do footing, then get cracking.
My questions are:
1.Which mortar do I use? I want it to be light coloured to match stone, but to last.
I've heard lime is good, but difficult to work with and less strong, although more flexible?
Some suggest a mix of lime, cement, sand? 1:1:5? Others say this is heresy. Which is it!? Any others have suggested snowcrete to make it lighter?
2. Also, once mortared, there will be space between the two skins of stone, as the wall is c. 60 cm wide at the bottom. Can this space be filled with concrete and small stones? Or does it need to be more mortar.
3. I want to include planters/flowerpot sunk in basins at each end – should these be made of different cement/mortar if plants will be watered? Do they need drainage channels?
4. Should I use wall ties, if so – how?
Any advice would be great. Thanks
