Repairing a Wooden Seawall in Florida

Body - Repairing a Wooden Seawall in Florida (wood seawall repair, how to repair a wood seawall)Residents next to Lake Padgett in Land o’ Lakes, Florida contacted Seawall Repair Network contractor Helicon regarding 650 feet of leaking wooden seawall. Depressions were appearing in the land behind the wall, holes were appearing in the wall, and soil was leaking through the wall into the lake. Initially, the residents just had the soil voids and depressions filled with more dirt. This solution didn’t last long, however, as the new soil eventually leaked through the wall and the depressions reappeared. If left untreated, this problem would have continued to erode the lakeside property and would have eventually become a threat to houses and structures near the water.

Repair Materials

The crew applied the Seawall Repair Network’s proprietary SW-RP1 repair material to stabilize the surrounding soil, fill the holes and voids, and stop the leaks.

Procedures

Helicon used Seawall Repair Network’s custom repair process and installation techniques to completely stabilize the wooden seawall and preserve its components. A barrier was installed to prevent the environmentally-friendly foam from floating out into the lake and all excess material was removed.

Results

The entire 650-foot stretch of failing seawall was stabilized and sealed for the long term with high-strength SW-RP1 seawall repair material.

Seawall Repair in Long Beach, New York

Body-seawall repair new york seawall repair in the northeast bulkhead repair northeastHurricane Sandy was devastating for much of the Northeast United States.  Many waterfront property owners are still recovering, and their seawalls, bulkheads, and revetments are still in need of repair and remediation.  The need for innovation and effective solutions has never been greater.

Seawall Repair Network contractor LJS Waterproofing answered the call recently and deployed to Long Beach, New York to save a waterfront property from further damage.  The Long Beach property was in danger due to an aging seawall that had begun to move, shift, and become damaged.

The crew applied the Seawall Repair Network’s patent-pending process, materials, and installation techniques to completely stabilize the seawall, and to preserve its concrete and steel components.  Upon completion of the Long Beach, New York project the customer stated, “This turned out so much better than expected.  I will certainly refer you to my neighbors and friends.”

A homeowner in Seattle, Washington hired Seawall Repair Network member contractor Ram Jack West to make repairs on their deteriorating bulkhead. Loss of soil caused voids behind the wall, which undermined the stability of the structure resulting in bowing at the midspan and cracks in the concrete. The seawall was only about 30 years old, with plenty of lifespan left if repaired properly.

Repair Materials

The Ram Jack West crew used helical tiebacks, SW-RP1 stabilization/water cut-off material, and pressure release technology to restore the seawall.

Procedures

First, the crew installed the helical tiebacks, which were required due to a failure of the original Deadman Anchor. Next, they injected SW-RP1 stabilization/water cut-off material behind the structure for permanent support. Then, they installed pressure release technology to regulate any hydrostatic pressure caused by future water build-up behind the wall. (In addition, this contractor installed carbon fiber reinforcement on the outside of the wall.)

Results

The result was a permanently stabilized seawall and preservation of the property behind it. The homeowner benefited from a solid solution at about 80% less than the cost of replacement. The patent-pending SRN repair process implemented by Ram Jack West restored the seawall without any damage to the customer’s adjacent property.

Protecting Drinking Water from Potential Flood Contamination

Body - Protecting Drinking Water from Potential Flood Contamination Protect Drinking WaterPlanners at Washington D.C.’s water utility, D.C. Water, decided to take proactive measures against potential flooding of their facility. Located right next to the Potomac, their facility could’ve been at risk in the event of an out-of-the-ordinary natural disaster. Determining that the main risk to the water supply in such a case would be permeation through sub-surface soil, they began installing a metal sheet pile wall deep into the substrate between the riverbank and the facility. However, in some spots, they were not able to drive a sheet pile panel into the ground because of underground utility lines or rocky substrate. The planners called in Seawall Repair Network contractor LJS Waterproofing to create sub-surface grout walls in those spots to fill in the gaps.

Repair Materials

The crew “constructed” these sections of the underground wall by injecting SW-RP1. This repair material permeates the soil, fills small voids in the soil, and cuts off water flow.

Procedures

LJS Waterproofing professionals used a Geoprobe to drive injection pipes into the ground (up to 33 feet in some locations). They then injected one gallon per foot using upward staging. The next injection point was 18 inches away from the first one. This process was repeated until a grout wall formed, filling the gap between the two adjacent underground sheet piles. For a large-scale job like this, they used a PolyShark single component grout pump manufactured by Alchemy-Spetec.

Results

With solid, impermeable grout walls filling in the gaps, a sub-surface barrier between the riverbank and the drinking water facility was now in place. The planners at D.C. Water were very satisfied with this solution.

Lakefront Seawall Repair in Wisconsin

Body - Seawall Repair Wisconsin Bulkhead Repair Wisconsin Seawall Contractor WisconsinThe owner of a marquee lakefront property near Genoa City, Wisconsin contacted Phase One Shoreline Solutions regarding their crumbling seawall. There was a 75-foot slope behind the wall, guiding rainwater down into the soil behind the structure. There was no drainage system in place, so the water in the soil created immense hydrostatic pressure over time. If the wall failed completely, the slope behind it would begin to erode into the lake, dramatically affecting the value of the property.

Repair Materials

The contractor repaired the structure with Seawall Repair Network’s SW-RP1, the installation of pressure release technology, and concrete patching and waterproofing coating.

Procedures

The crew began by injecting the high-strength SW-RP1 repair material into the soil behind the wall in order to provide structural support and stop water leaks. Next, they repaired the cracks in the wall with high-performance patching concrete. After that, they installed pressure release technology in order to prevent future hydrostatic pressure build-up. Finally, they coated the entire wall with waterproofing cementitious coating.

Results

The dramatic before and after pictures included in this case study indicate the effectiveness of this repair job. The original strength and appearance of the wall were restored. Safeguards were put into place to alleviate the cause of degradation, thus preventing future damage. The customer emailed the contractor with a simple three-word response to this repair job: “I love it!”
