Pin
pile driving (also referred to as micro piles, micro-piles, or micropiles) is an alternative method of retaining wall construction, soil stabilization
and foundation footing. Some of the many benefits of using this method are: little or no
excavation needed; often costs less than traditional methods, often does not require heavy
machinery, thereby allowing solutions to problem sites with limited access. Pipe, varying
from 1.5" to 6" in diameter and up to 32' in length, is driven into the ground
with pneumatic hammers. Pro Landscape, Inc., has developed a reputation as the contractor
with the most expertise in pin piling in the Portland Metropolitan area.
Above is a residential property in SW Portland that had a back yard with a steep slope,
creating a not very useful area. Our client wanted to level the back yard, but it was not
practical to build a retaining wall by conventional means, requiring excavation. The
solution was to create a pin pile wall by driving 4" galvanized pipe into the ground
with a pneumatic hammer. Maccaferri Gabion wire mesh was attached to the pipe. This wall
was then backfilled with rock and soil, creating the level back yard seen in the photo
below. |
