Interior waterproofing manages water after it enters the basement, using drainage channels, vapor barriers, and sump pumps to move water out. Exterior waterproofing prevents water from entering by applying a waterproof membrane around the foundation, installing drainage systems, and directing groundwater away from the property.

Waterproofing your basement prevents water intrusion, which can lead to mold growth, structural damage, and costly repairs.

Look for damp spots, mold, efflorescence (white powdery deposits), musty odors, and water stains on walls and floors.

By preventing moisture buildup, waterproofing reduces the risk of mold and mildew, which can cause respiratory issues and allergies.

Yes, a dry basement helps maintain consistent indoor temperatures, reducing the need for heating and cooling, and lowering energy bills.

Absolutely. A dry, well-maintained basement adds value to your home and makes it more attractive to potential buyers.

Yes, waterproofing helps redirect water away from your basement, significantly reducing the risk of flooding.

Exterior waterproofing addresses issues before they reach the foundation, providing a more permanent solution

The cost to waterproof a basement can vary widely depending on the chosen method and the specific conditions of your home. Interior solutions like waterproofing paint and sealants are more affordable but may not provide long-term protection for severe issues. Exterior solutions, while more expensive and disruptive, offer a more comprehensive and permanent fix. It's important to assess the severity of your water issues, consult with a professional, and choose the solution that best fits your needs and budget.

The longevity of waterproofing depends on the method used and the quality of the materials. Regular maintenance can extend its effectiveness.

• Interior methods like waterproofing paint and sealants typically last 5-10 years
• Interior trenching with a drainage system can last 20-30 years 
• Exterior paints last 5-15 years
• Membrane waterproofing can last 10-30 years
• Cementitious waterproofing is designed to last the lifetime of the structure, often over 30 years
• French drains, which redirect water away from the foundation, can last 20-50 years

While some minor waterproofing tasks can be DIY, it's often best to consult a professional for a thorough assessment and effective solutions.

Foundation cracks can be caused by natural settling, hydrostatic pressure, temperature changes, or poor drainage. Proper drainage and waterproofing can help prevent new cracks.

Yes, smaller cracks can often be sealed from the inside with epoxy or polyurethane injections. Larger or structurally significant cracks may require exterior repair, reinforcement, or consultation with a structural engineer

For exterior waterproofing, excavation is typically done to the depth of the foundation’s footing, usually between 6 and 10 feet. A trench about 2 to 3 feet wide is recommended to allow for waterproof membrane application, drain installation, and backfilling.

Permits may be required, especially if exterior excavation is involved. This is based on municipality.

Sump pumps should be inspected and tested annually. Maintenance includes checking for debris, ensuring the float switch functions properly, and verifying that the discharge line is clear.
