Stonewall Masonry

 

STONE MASONRY WALLS

At John McGowan and Sons we provide complete masonry services – from the initial planning to placing the final stone or brick into place. We offer masonry expertise on new projects, restoration projects and repairs. As always, we offer free estimates on all masonry work.

Retaining Walls And Keystone Walls

Performed by first excavating a new trench at 8”-12” in depth. We then remove excess fill material from the site and compact new base material using a vibratory plate compactor. When the compacting is complete we install geogrid mesh every 2-3 courses, depending upon requirements set forth. All compaction shall be done in 2 to 4 inch lifts, followed by the placement of stone units side-by-side, set level in all directions. We back fill the wall with clean granular fill or gravel, as agreed upon. A filter fabric is installed between the fill and wall stone to prevent wash through. Finally, we add a wall cap as desired and agreed upon.
