Many houses are plagued by flooded basements every year during rainy and snowy seasons. Several dry basement systems can be purchased to help prevent damage from moisture caused by backed-up and overflown sewer drains.

Sometimes water collects outside the house near the foundation walls. Once the water saturates on the ground adjacent to your house, hydrostatic pressure squeezes through the foundation, and the slab cracks. The more it rains or snows outside, the more the basement floods.

What Is the Solution to Basement Flooding?

The best solution is usually to regulate water flow from the roof, siding, and gutters. Ensure that water is removed a safe distance away from the ground surrounding your house.

Once the water flow is diverted, it is important to seal and repair any cracks in the foundation walls and slab; however, even these are only preventive measures that may not work. That is especially true if the rainfall and snow are intense. If water is still pooling in the basement, it may be time to install a dry basement system.

What Is a Dry Basement System?

Dry basement systems are defined as any installation that either waterproofs your basement floor or drains the water that finds its way in. Install one of these systems to ensure that your basement floor stays dry.

Once the floor is waterproofed or adequately drained, your basement will remain dry throughout the year. There are two types of dry basement systems: waterproofing and sump pump systems.


The simplest and least expensive system to install is a waterproofing system. Simply reinforce the foundation and floor with waterproof cement. Keep in mind that by just waterproofing the foundation and floor, you cannot fully guarantee that your basement will be dry forever.

The ideal way to go about it is to waterproof the basement and then find a way to drain the water that collects under the foundation and slab.

Sump Pump System

Sump pumps automatically expel water that comes under the basement long before it can collect into pools. The system uses specialized rocks and tiles to fence the foundation and reinforce the floor so that any water collected is drained immediately to a basin that’s buried at a lower point under the same basement floor.

Once water fills the basin, the pump automatically discharges the water into an outside drain via a hose.

A properly designed dry basement system drains water to ensure that the water level above the basement floor and slab never reach such levels as would allow hydrostatic pressure to accumulate. Again, this must then be complemented with repair work to seal any cracks on the floor.

The net result of a properly installed dry basement system is a dry basement that not only eliminates water seepage but also prevents future flooding.
