Signs of Moisture Penetration
In the corner, groundwater seeping through these basement walls has breached any damp proof coating, caused the walls to crack, and chipped off the paint.
Leakage Under Basement Door
Groundwater leaked into the outside stairwell and ran across the basement floor. Notice how any items being stored in the basement are susceptible to water damage.
Signs of Groundwater Leaks
The painted basement wall has chipped and cracked, and the basement floor is damp at the perimeter—two clear indicators of groundwater leakage at the wall-floor seam.
Hydrostatic Pressure
As hydrostatic pressure increases and moisture penetrates basement walls, walls may begin to crack and leak, and signs of groundwater seepage become apparent.
Sump Pump Failure
Sump pumps are mechanical and require a power source to operate. In this case, the existing sump pump system just wasn't powerful enough to keep up with the amount of water leaking in. In addition mechanical failure, the existing system did not include a battery backup to protect the basement in case of power outages.
Leaky Basement Stairwells
Beware of water when a basement has its own entrance. Outside stairwells can fill with rainwater, and groundwater can leak underneath the steps. Either way, a basement with an outside entrance is susceptible to leaks.
Double Protection Against Groundwater
Two sump sumps provide double the protect against groundwater leaks, and each pump has a designated discharge line to allow twice the amount of water to be discharged.
Battery Backup Sump Pump
A battery backup sump pump is optional but critical. If one or both of these pumps were to fail or the home lost power in a thunderstorm, the third battery backup pump would continue to pump until the other pumps were serviced or power was restored.
Preventing Frozen Discharge Lines
No basement waterproofing system is complete without IceGuard. IceGuard protects basements from groundwater leaks by allowing sump pump discharge lines to expel water in spite of freezing temperatures.
