Basement Waterproofing questions, answered by experts

Statistics show that 98% of basements will experience some form of water damage over time. However, that doesn’t mean all basements will experience severe flooding. The best way to prevent a water-damaged basement is to keep up with home maintenance and have proper drainage installed outside your home to direct water away from the foundation. You can also consider building a flood wall around the house if you live in a flood-prone area.

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.

Most people consider a French drain to be one of the most effective solutions for foundation leaks, but it’s not always a standalone solution. French drains will help keep water away from your foundation to reduce the risk of leaking and structural damage from soil expansion, but depending on your foundation type and location, you might need other systems or techniques—like soil gradation and gutter and leader installation—to resolve the underlying problem.

Water that pools under pavers can erode the soil foundation and weaken the paver structure. In some situations, it can also cause mold and mildew growth. If that happens, you may need to start budgeting for the cost to build and install a patio to replace the damaged one.

The most challenging part of finishing a basement is addressing moisture control. Basement waterproofing is an essential task that requires a professional’s skills and knowledge. If you don’t properly waterproof your finished basement, it’ll be vulnerable to dampness, water damage, and mold growth. Ensuring proper insulation and ventilation to combat these issues while meeting building codes adds complexity to your remodeling project.
