Are you looking to create a visually striking and unique set of stairs in a wall project? Look no further than CornerStone® 100 stairs. These stairs are designed with features, such as a hollow core and SecureLug, making the installation process simple.

This section provides step-by-step instructions for using CornerStone® 100 to construct stair details. After reading this blog post, you will learn how to:

prepare the base leveling pad
lay the first, second, and third courses
fill the cores with concrete or gravel
add stair treads
create risers
and more

This guide can help anyone create beautiful and practical stairs for any wall systems.

Step 1: Base Leveling Pad

When building steps, exercise the same care used in typical retaining wall design and construction.
Prepare the sub-base and base leveling pad by following Gravity retaining wall CornerStone® Installation Steps 1 to 9.
Build each step in sequence with each course of the regular retaining wall units for best results of wall to step interlock.

Step 2: Lay the First Course

CornerStone® first base units will have the SecureLugs removed before placing on the leveling pad.
The first course of step units will be completely buried.
Backfill behind the first course units with gravel, then compact and level flush to the top of the first course.
Do not fill the step units’ hollow cores with gravel if you plan to use concrete.

Step 3: Lay the Second Course

Place the second course of units on top of the base units.
Place a second row of units back-to-back behind the second course of units on
half bond.
Backfill behind the second course of units with gravel, then compact and level flush to
the top of the second course.
Do not fill the step units’ hollow cores with gravel if you plan to use concrete.

Step 4: Lay the Third Course

Place the third course of units on the lower backward facing units with the SecureLugs placed into the 2 hollow cores of the lower units on half bond.
Pull the units forward to lock the SecureLugs into the lower backward units.
The third course units will be in a forward batter approximately 1.5 inch leaving 10.5 inches exposed on the front first step.
Place a second row of units back to back behind the third course of units on half bond.

Step 5: Continue Installation

Continue to install each course of step units following the same steps as above.
The top and final step does not need backward units.

Step 6: Concrete Core Steps

Concrete filling the cores of all the step units will provide for greater stair stability.
Flush the concrete/gravel core infill to the top of the units.
Use a steel bar to hand-vibrate the cores to insure proper filling.
Option: Unit cores can be filled with gravel but must be well compacted.

Step 7: Stair Threads

CornerStone® 12-inch deep cap units can be used as a stair tread.
Option: Pavers, Patio Slabs, or Natural Stone can also be used as a stair tread.

Step 8: 8″ Riser Cross Section

The 12-inch cap will overhang the step units by approximately 1.5 inch on each step.
The riser will be a full 8 inches using the above installation.
Properly secure the cap units using a concrete adhesive.
Make sure all units are free of dirt and stones before installing.
Place a bead of adhesive between each joint of the caps.

Step 9: Lower Step Risers

Lower risers can be made, such as 6″ or 7″, by lowering the buried units 1 to 2 inches below the top of the backward buried unit.
Larger treads can be created by moving the buried units back off the forward step course 3 to 4 inches to create a 15 to 16 inch tread.
A variety of riser heights and tread lengths can be created to suit your project.

Wrapping Up
