Water resistant, ALLFlex® is a proven application as a sea wall joint seal. The coating is currently contracted by the New Orleans Levee Board along Lake Pontchartrain in Louisiana. It has been 10 years since first application in parts of the wall and ALLFlex® continues to strengthen miles of sea wall and protect the city from environmental damage.
The achilles heel to the entire sea wall is the expansion joint. If a joint or seam fails, then water rushes through it, picking up dirt and debris, ultimately --- damaging the seawall. Maintaining the seams is a fraction of the cost of full wall maintenance or repair if breakdowns start to occur.
Durability is the key and ALLFlex® delivers. It’s been ten years since its first installation in the Lake Pontchartrain sea wall and it continues to survive with no detectable erosion or soil intrusion. ALLFlex® survived thirty foot Hurricane Katrina storm surge and according to New Orleans levee board officials, it has outperformed all other competing materials installed in the wall. Our experts believe it will hold for another ten years.
