Pillars add a finishing touch of elegance to any CornerStone® wall project. They can be used to create distinguished entranceways to any residence or business and the unit’s hollow cores greatly simplify the placement of lighting in the pillars. This section provides simple instructions for the creation of a 27″ pillar.
Step 1: Levelling Pad
- Excavate and prepare your Sub Base Leveling Pad
- Install leveling pad of well graded gravel (also known as road base aggregates)
a minimum of 8″ (200 mm) thick and 40″ (1000 mm) square. Compact to 95% standard proctor density - Install the first 4 corner units perpendicular and square to each other
- Ensure first base course is level and square to the center of the pad
- Bury the first course completely for stability
Step 2: Second Course
- Place second course of the CornerStone® 90° Corner units directly on top of the
first course - Flip and turn the second course corner units upside down to create an overlapping bond
- Clear Crush Drain Gravel (Angular Aggregates free of fines) should be placed in
the cores and middle of pillar - (concrete core filling optional) use a dry concrete mix to prevent leaching of cement
- Concrete Adhesive should be applied to all units to ensure course to course interlock
Step 3: Additional Courses
- Repeat Step 1 and Step 2 until desired height of pillar has been reached
Step 4: Completion
- Complete the pillar with a Pillar Cap
- Secure the Pillar Cap with a concrete adhesive *Pillar cap approximately 32″ (508mm)

CornerStone 100 Gravity Retaining Wall Installation
Gravity (SRW) Cornerstone retaining wall systems are structures lower in height that use the CornerStone® unit weight combined with gravel core infill to resist earth pressures behind and on top of the wall. The 5/8"/unit (4.5 degree or 1"/vertical foot) batter or setback of the CornerStone® retaining wall along with proper soil conditions below and behind the wall provide the stability of the structure. Below is a step by step for CornerStone 100 Gravity Retaining Wall Installation. For walls 4.0ft (1.2m) and taller a qualified engineer should be consulted. CornerStone 100 Gravity Retaining Wall Installation This guide can be used for CornerStone 100, MiraStone, FrogStone, Panomur Step 1: Planning Your Retaining Wall Project Call before you dig & contact local authorities or city planning to ensure you follow proper guidlines Mark the bottom and top of the retaining wall excavation location with spray paint or stakes Establish proper elevation >More
CornerStone 100 Geogrid Wall
Creating a CornerStone® reinforced retaining wall system, involves the use of geogrids for reinforcement. Cornerstone geogrid retaining walls 3.5ft (1.07m) and taller will automatically have active pressures because of their height. Retaining walls smaller than 3.5ft (1.07m) may also require geogrid reinforcement depending on other related factors. Parking lots, roadways, or positive slopes above walls for example, require the use of reinforcement to help resist the increased pressure behind the wall. Geogrid used with the appropriate lengths, layers, and compacted backfill materials will resist these active forces above and behind the wall. For CornerStone 100 geogrid reinforced retaining wall 3.5ft (1.07m) and taller a qualified engineer should be consulted.
