Nothing is as permanent as stone. In the garden, stone adds a feeling of
stability. Single pieces of stone tend to add a calming effect to the
appearance of a design. Ancient gardens throughout the world reflect this
as do many modem gardens.
Slabs, or what are sometimes referred to as Outcroppings, are large flattish
pieces of natural stone that can be worked into landscape designs in
countless ways. Stacked vertically, they make a bold and stable retaining
wall. Built into a gentle slope, they make a dramatic setting for rock and
alpine gardens. Larger slabs may be used in various erosion control
applications.
Boulders are large stones that may be rounded or angular. Angular boulders
reflect newer origins, having been broken or blasted from a quarry face.
Rounded boulders reflect weathering, or, in the case of granite boulders,
glacial origins. They can be grouped, or stacked, to create a massive
retaining wall. Or, placed along the course of a stream, to create scale and
interest in a water feature.
Both boulders and slabs are popular for use as signs, address markers or
simply as single accent pieces in the garden.
Split Slabs:
For unique applications, Lang Stone has the capability to split slabs to your
specifications. For large-scale retaining walls, this is a great way to achieve
a massive look and attain a higher square feet per ton yield.
Estimating:
All boulders and slabs are priced by the ton and are sold individually or by
the truckload. Due to the natural shapes, estimating is done on general
terms using approximate cubic foot measurements.
Calculations
For angular boulders, use the slab method below.
For single round boulders: In feet, calculate the area of a sphere of the
approximate diameter of a desired boulder (A= 4/3 x Pi x radius cubed).
Note: An ellipsoid of the same diameter and twice the length of a sphere,
equals two times the volume of the sphere.
For a single slab: In feet, calculate average thickness x average length x
average width = CUBIC FEET
For a wall: In feet, calculate average height x average depth x length =
CUBIC FEET
Cubic Foot Weight of Limestone = 165
Cubic Foot Weight of Sandstone = 150
Cubic Foot Weight of Granite = 175
All Lang Stone slabs are delivered to your site on pallets. On some volume
projects, optional dump load deliveries may result in savings.
