Every once in a while, a truly fantastic product comes along. SmartSlope is one of those products! The benefits include: excellent block dimension tolerance, a 100% mechanical connection to the reinforcement, a huge pocket for holding soils, the ability to batter at 20 degrees or flatter, and the ability to install drip irrigation lines directly into the block!
Here's a video about the system:
So, we are talking about the Living Wall: the most environment-friendly block on the
market and the only block with a true 100% mechanical, verifiable
connection.
Global Stability is the stability of the hillside ABOVE and BELOW a retaining wall. By it's very existence, a retaining wall changes the shape of a hillside. These changes should be addressed by the Engineer and Contractor to determine if the hillside is stable. Take a look at these sketches, photos and video:
When this 38-foot high retaining wall failed, Kowalski Engineering was retained to help. Our services included determining what caused the failure, redesigning the new retaining wall, and reviewing the new wall's construction.
Many of the retaining wall blocks were reused on the project - demonstrating that these blocks are extremely durable, even after being dislodged from such a height. You see, the large and durable block facing was not the problem.
Retaining Wall Failure: upper portion collapsed
The problems were: the type of soil used during construction, the spacing of the geogrids, and (you guessed it) water. Remember this recipe for failure: "Just Add Water".
Good design and good construction will account for the "added water" and a retaining wall will be quite stable. We engineered the new retaining wall and reviewed its construction.
In Cincinnati, Ohio we have our fair share of retaining wall failures:
due to poor construction, poor design, or sometimes just age! In this
case, a number of factors contribute to a failing retaining wall that is
literally shoving a building sideways!
Photo of failing old stone retaining wall pushing building sideways!
At this location, a natural stone retaining wall was
constructed outside an apartment building. The foundation walls of the
apartment building and this stone retaining wall are supporting the land
adjacent to them.
However, at some point in the past another retaining wall
was added above! This additional retaining wall was constructed just a
few feet away from the apartment building. The nearby wall is about 6
feet high, and adds a huge amount of loading to the basement/foundation
wall and to the natural stone wall.
The basement wall is being held in place at the front of the building
and at the middle of the building, because there are walls at a
90-degree angle to the basement wall. Those walls are supporting the
basement wall.
However, at the rear, where there are openings for the
garage doors, there is little support. The top of the garage doors has
been shifted a few INCHES sideways, and the back wall of the apartment
building is bulging outward. Even the old stone wall is being pushed
outward.
The owner is currently exploring options for repair!
Retaining walls are failing daily in all parts
of the world due to the lack of proper erosion control. The JET FILTER
prevents seawall failure by relieving pressure and allowing drainage
while saving time & money on extensive repairs.
The JET FILTER relieves the hydrostatic pressures created by rain water
as well as tidal surges trapped behind erosion control structures such
as:
Seawalls
Bulkheads
Retaining Walls
Sheet Piling
Because of its unique design, the Jet Filter allows water behind walls to escape, but retains the soil.
