RETAINING WALLS
with W-BEAMS
Retaining walls can be used to expand a backyard.

The vertical steel beams are W beams, which are placed in deep holes, cleaned and primed to one foot below ground, and then concrete is poured in the holes.

Later, pressure treated lumber or reinforced concrete is placed between the W beams to create the wall.
Many owners opt for reinforced concrete between the W beams for a better-looking and longer-lasting wall.

In this photo, the owner stained the concrete between the W beams with concrete stain.
Avalon has fixed too many shabby retaining walls to consider putting our name to one that won't last.

We prime our W-beams before pouring concrete to protect them from rust at grade level.

To ensure the longevity of the retaining wall, we strongly recommend not using wood planks, but instead reinforced concrete or pressure-treated wood.
Avalon builds concrete walls with continuous horizontal rebar between the W-beames. This wall is ready for more formwork and then concrete to encase the rebar.

Such a wall is stronger than one built with wood planks or pre-fabricated concrete planks.
Concrete walls can be stained soon after pouring.

We recommend Smith's earth-friendly, water-based Moss Green, Olive Green, or Bark Brown for natural look.
