BUILDERS

Traditional Dry-Stack Stone
Walls
Stone Masonry originated with
dry-stacked stonework where the walls are carefully laid up
without mortar. Gravity serves as the glue that holds everything
together. Free-standing dry-stack stone walls are usually made
larger at the base and then taper in slowly as the height
increases. For absolutely no expense but the labor, farmers
built miles upon miles of stone fences this way in Ireland and
in the northeastern states. Many old Irish houses were built in
a similar way. Where "mortar" was used, it was often merely mud
or limestone plasters with little strength. The mortar
functioned as caulking to stop the flow of air, rather than as
cement to bond the stones together. Short, dry-stacked stone
walls are especially ideal for landscaping projects. Taller
walls require more skill and time. For more details on dry-stack

Traditional Mortared Stone
Walls
Mortared stone walls evolved out of
dry-stack stone work with the emergence of cement mortars. The
first cements were made of burnt gypsum or lime mixed with water
to make a paste with slight bonding capability. Stone walls
still had to be built as carefully as they were without mortar.
The cement paste just filled the gaps between the stones and
cured to form a soft, rock-like substance.
A retaining wall is a structure
that holds back earth. Retaining walls stabilize soil and rock
from down slope movement or erosion and provide support for
vertical or near-vertical grade changes.
