Basement waterproofing is the permanent answer to a basement that keeps getting wet: interior drainage channels, sump pump systems, crack injection, and moisture sealing engineered to redirect water before it reaches your floor. If there's standing water in the basement right now, extraction and structural drying come first — then waterproofing makes sure you never do this twice. Crews assess the water path (hydrostatic pressure, grading, foundation cracks), then build the drainage and pumping system that matches it.
Kenner context: Kenner area water damage risk in Louisiana includes the constant threat of tropical weather from June through November, year-round high humidity that accelerates mold growth to within 24 hours of any moisture event, and aging infrastructure in many communities that experiences sewer and drainage failures during rain events. Louisiana's subsiding coastline has put more properties into FEMA Zone AE flood zones each decade. Louisiana Department of Insurance requires insurers to pay flood claims within 30 days of receipt of proof of loss — contact the LDI if your insurer is delaying.

If water is standing now, extraction and drying come first — waterproofing installed over saturated materials seals the moisture in behind the new work.

Local Risk Notes
The Laketown area along Lake Pontchartrain's southern shore in northern Kenner and the Chateau Estates and Vintage subdivisions face the highest flood risk, combining proximity to the lake levee system with the city's lowest elevations. The older neighborhoods surrounding Veterans Memorial Boulevard, developed before modern floodproofing standards in the 1960s, sit the farthest below sea level and depend entirely on Jefferson Parish's pump system remaining operational to stay dry.
LA Insurance Tip
Obtain an elevation certificate and compare your property's actual elevation to the published Base Flood Elevation — properties below BFE carry higher NFIP premiums, but investing in elevating HVAC equipment, electrical panels, and utilities above BFE can meaningfully reduce both flood insurance costs and future storm damage.
