Why is my car leaking water when parked?

Coolant may leak from a car for a number of reasons. The most common are: radiator corrosion; a damaged coolant hose; or a water pump with a leaky gasket. In the vast majority of cases, water leaking from under a vehicle is usually condensation from the air conditioning system, or from the exhaust.

A puddle that appears on the floor of your car’s interior — unless you can trace it to a spilled beverage — probably means you’ve got a leak somewhere. It could be a leak that allows rainwater into the cabin, or a leaking component inside the car that’s causing water to leak from behind the dashboard.

What causes a leak in a subterranean parking garage?

Water leaks in a subterranean garage can occur during construction before the above-grade building walls are tied into the upper termination of the below-grade waterproofing. In these cases, water infiltration that occurred during construction typically ceases once the above-grade envelope and final grading around the garage have been completed.

How can you tell if there is a leak in a parking garage?

When assessing the water leakage, moisture entering the garage can manifest as liquid water, discoloration on the surface of the garage wall, and/or as efflorescence (i.e. white powdery deposits that are actually soluble salts left behind on the surface of the concrete through evaporation of moisture).

How does water get into a parking garage?

When water within the surrounding soil makes its way past the waterproofing membrane and reaches the backside of the garage walls, the water then travels until it ultimately finds a pathway into the garage. As such, the location where the water manifests within the garage is not necessarily the point in which it bypassed the waterproofing assembly.
