Modifying Wall Blocks

Modifying AB and AB Europa Blocks

SAFETY FIRST: Always wear safety glasses when splitting or cutting concrete retaining wall blocks . A dust mask is recommended when cutting blocks.

• Use a masonry saw with a diamond cutting blade or a metal chop saw with a dry cutting diamond blade.
• NOTE: Masonry saws and metal chop saws are available for rental at most retail centers.

Modifying AB Capstones

Capping a curved retaining wall takes a bit of cutting and fitting, but produces a beautiful finish. Be sure to wear appropriate safety gear, including protective eye wear, dust mask, and hearing protection when cutting, and operate power saws carefully.

Capping Curves

• Place two caps on top of the retaining wall, spaced so a third cap will fit tightly between their widest point.
• Set another cap on top of the first two caps in the center and mark where they overlap on the bottom of the center cap.
• Remove the center cap and cut along the marks. Then set in place so the three fit tightly together.
• For complete details see instructions on building curved retaining walls.

Capping Corners

• Cut caps at 45 degree angles to complete the inside corner and give the wall a custom finished look. It's a good idea to secure caps with a high strength construction adhesive once they are all cut.

Modifying Anchoring Units for AB Fieldstone

AB Fieldstone retaining wall

• Removing the “wings” of the blocks will be needed on projects with curves, corners or step downs. For smooth outside curves, remove one or both of the “wings” from the back of the anchoring units and tighten the radius of the curve. Break wings off with a hammer and chisel in the existing score line to obtain a clean break.
• When working with corners and/or stepping down a wall, split an anchoring unit in half to tie the corner together. Split the block by using a hammer and chisel to make a break down the center of the block.
• On some projects you will need to modify the bottom lip of the block to fit on the course below. Use a hammer and chisel and tap along the lip to remove.
