Miami Seawall Repair

Miami Seawall Repair

In Miami seawall repairs are a common problem faced by coastal residents. A waterfront Seawall is constantly
stressed by water flow, via tidal flux, and seasonal storms. No matter how well engineered eventually all seawalls and bulkheads will face erosion and weathering and due to this all Seawalls will require repairs at some point and may require a constant watchful eye. Seawalls can be an engineering marvels if built right. Frequently, however, their construction is less than perfect and after only a few years they start to show signs of stress and begin eroding fine soils and silts under and through cracks in a Seawall. This can pose a serious problem to structures near or adjacent to the wall after soil erosion begins. Often, these depressions indicating voids are covered by vegetation and are tough to spot. Seawalls requiring repair can also pose a huge threat to nearby buildings once the soil erosion begins. Once it begins, it’s a constant and usually losing battle to repair the erosion areas. Cracks and holes allow eroded soil to flow under and through a deteriorating seawall creating larger and larger voids without new soil placed to keep proper soil compaction to support these structures. Continual rainfall, surge, tidal action, poor irrigation and run-off might amount to swiftly compounding and pricey repairs thanks to soil erosion or “Voids” beneath soil and behind seawalls producing the need for costly seawall improvements in Miami.

Signs which display behind seawall soil erosion are the following:build-pg2
-Drop in soil at the back or near any seawall
– Pooling of normal water behind or in close proximity to wall
– Hollows or voids growing hiding behind wall structure
– Horizontal breaks just below the seawall cap
– No “air flow” to allow h2o to empty via seawall sheet piles
– Horizontal cracks in the seawall in close proximity to barnacle line

Anchor failure indicators – What to look for:
Extended contact with saltwater where corrosion has deteriorated the Anchor Rod and
fasteners to a point where excessive weight or loading from behind the walls generates probable
setbacks of the walls demanding pricey seawall repairs.

Signs that signify anchor failure for Miami seawalls are usually:
– Degeneration of the Anchor Rod
– Serious movement of the seawall
– Imbalance of seawall pilings and walls

Seawalls within Miami cap failure – things to search for:
Extended exposure to saltwater which has prompted corrosion in the structural steel triggering breaks to build up. Because the steel continues to wear away and expand areas of the cap may break off, therefore destroying the cap, ultimately causing a collapse of a the seawall requiring maintenance.

Signs that indicate cap failure of a Miami seawall are:
-Outward movement of the seawall
-Misalignment of the seawall
– Horizontal cracks in the face and the surface of the current seawall cap
– Bits of the cap are lacking or intending to fall off

Sheet pile failure signs – What to look for:
Lack of berm in-front of the seawall or bulkhead causing the toe of the seawall wall to go outward at the bottom. Excessive buffering from behind leading to broad splits to occur on the seawall sheet piles, exposing the strengthening steel to saltwater. Extended contact with the elements breaks down the sheet piles, that will cause collapse of the seawall.

Indicators that suggest cap failing of a seawall inside Miami are:
– Misalignment of the seawall
– External movement of the seawall sheet piles (typically at barnacle line)
– Horizontal breaking in face of the seawall sheet piles (generally at bottom of seawall cap or
middle area of wall)

The physics of soil erosion on a Miami seawall :
Seawalls within Miami are generally prone to erosion despite the fact that they are made to prevent invasion of water from sea, lakes, streams as well as contain the bordering soils, while getting continually assaulted and damaged by climatic conditions, gravity, mounting and falling tides, boat wakes, currents, seasonal h2o level variations, and so forth. During large rain incidents, a seawall in Miami has to be capable to “exhale” or “vent” recently absorbed h2o in the soils out into the nearby waterway or canal. If the water is not “exhaled” the resulting serious pressures can damage and destroy seawalls in Miami.

Simply because water seeks the route of least resistance, it will find any fragile section like a panel joint or crack and eventually break a wall panel creating a catastrophic wall failure. In a “worse-case scenario”, the water will exit underneath a sheet pile or wall taking earth along with it. This may trigger extremely weak soils and therefore soil erosion occurs at a swiftly increasing rate. Because poor dirt zones collapses are only a matter of time. We’ve had instances where you could actually see the soil colour variance in the water close to the the seawall structure due to soil seeping out. This type of soil erosion isn’t prone to happen if the hydrostatic (water) pressures are equalized in a thoroughly sealed then vented seawall. Avoid additional property damage of property simply by putting a stop to seawall erosion. To save a possible fortune in deferred maintenance costs good maintenance of your Miami seawall is self-evident and the faster you act the better! We can help.
