|Stone Retaining Wall with Steps|
It’s hard to have an al fresco dinner party on a slant. For properties with a slight slope, a decorative stone wall might be the right landscape solution to straighten up the sloping land into two flat areas. This creates two levels in order to provide one flat surface for lawn games like badminton or croquet, and a second level area for dining, relaxing and outdoor living.
Ask your Crabapple LandscapExperts Rep if the sloped area can be graded with a bobcat, flattening it out by means of a low drop (17 to 20 inches) that can also be used as seating. A low sitting wall helps define the space as well as provides additional seating for outdoor entertaining. Low retaining walls also function as a backdrop for plantings and colorful flowers.
If the grade is more sharply sloped, perhaps a series of 2 or 3 low retaining walls can create an attractive series of level terraces. Call the LandscapExperts for retaining wall issues relating to erosion, water seepage, soil texture, tree root zones or local restrictions that require expert know-how.

eparate out the capstones, (wide, flat stones for the top of the sitting wall), and reserve them for finishing the top.
To determine how much stone is needed, the formula we use for # of cubic yds. = L' x W' x H'/27. In other words, multiply the proposed length, width and height of the sitting wall in feet and divide by 27 to determine the number of cubic yards of stone needed. Convert this to tons instead of cubic yards by multiplying by 1.5.

Building on the foundation, we lay stones along the extent of the wall from one end to the other, choosing stones that fit together like pieces of a jigsaw puzzle. It is best not to lay one stone upon the other, but to interweave or interlay them so that a top stone covers the gap between 2 or 3 stones in the row beneath, exactly like bricks are set in a brick wall.
Small stones are useful for filling gaps between the rocks and stabilizing them.
Backfill soil also can be used to make planting pockets for ferns or wallflowers.
When the desirable height of the wall, less the thickness of the capstones, has been reached, it is time to finish it off laying on the capstones from one end to the other. Once all the capstones in place, we backfill with a sandy topsoil and plant with turf or herbs and flowers.
