Jumbo Nursery Stone Retaining Wall Installation Guide
STEP 1: Begin at the lowest elevation. Determine line and height of wall. Dig a trench 6" deep and 12" wide. Fill the trench
halfway with level, compacted gravel.
STEP 2: Install first course of blocks. Check for level side-to-side and front-to-back. Fill between and behind the blocks with gravel. Brush excess gravel from top of blocks.
STEP 3: Position next course of blocks on top of the first course, utilizing the cross bond pattern.
STEP 4: Continue leveling from sideto-side and front-to-back, compact all loose dirt behind the wall.
STEP 5: Finish off by landscaping
surrounding area.

Retaining wall general installation guidelines
Decorative retaining walls are retaining walls that are under 4 feet in height and generally add an aesthetic touch to your home landscape. These retaining walls may be functional, in that they may hold dirt in place, such as when used for a planter, but their application does not affect the safety or structural soundness of tiers or terraces. If in doubt, contact a qualified landscaping contractor or lanscaping architect.
What you should know before you begin your project:
Soil conditions, land slope and water table will affect final design of your retaining wall.
A minimum of one-half of the first course of block should be placed below grade line of the soil.
6" Jumbo NurseryStone is typically suitable for retaining walls up to 4 ft. tall. Consult local codes and site conditions to determine your specific limitations.
Walls require a minimum of 2" of gravel base.
How many retaining wall blocks do you need? Multiply the square footage of your retaining wall by 1.5. Determine the square footage of your wall by multiplying length x height.
