What are dry stone walls made of?
Limestone dominates the walls, although sections built of sandstone or breccia occur where these rocks form the uppermost strata.

Which stone is use for stone wall?
Stone walls are usually made of local materials varying from limestone and flint to granite and sandstone.

Most older walls are constructed from stones and boulders cleared from the fields during preparation for agriculture (field stones) but many also from stone quarried nearby. For modern walls, quarried stone is almost always used. The type of wall built will depend on the nature of the stones available.

What holds dry stone walls together?
Dry stone walls are durable because they contain no mortar, but are held together by the weight of stone, and by the skill of the builder who selected and fitted the stones together.
Why do dry stone walls fall down?
Dry stone walls are built without any cement or mortar holding them together. The way the stones are placed on the wall helps hold the structure in position. This allows the wall to settle naturally and to survive frost, which can cause cement to crack and the wall to collapse.
What is the best mix for a stone wall?
Cementing. Make the mortar mix from one part cement and two parts sand. Do not use dehydrated lime as it discolors the stone. Mix completely while dry, then add water until mortar slips cleanly for the hoe.

How thick should stone wall be?
All dry stone walls should be constructed with the thickness equal to half of the overall height. Walls should be built leaning back toward the slope about two inches per foot of height for stability.
How does a dry stone wall stay up?
You stretch lengths of string between the frames to act as guidelines, and a plumb bob ensures the wall stays vertical. A dry stone wall is actually two separate but interlocking walls, tied at regular intervals by longer through or tie stones, and a middle filled with a mass of smaller rocks and pebbles.
