After decades in basement waterproofing, I’ve seen homeowners waste thousands on solutions that don’t last. The truth is that not all basement waterproofing systems are effective, and what works best depends on your home’s specific issues.
Basement Waterproofing Options
Here’s a breakdown of the most common options and what works in Maryland homes.
Interior Waterproofing: The Best All-Around Solution
For most homeowners, interior waterproofing is the smartest choice. Instead of trying to keep water out (which isn’t always possible), it captures and redirects it before it causes damage.
- Interior Drainage Systems: A trench along your basement’s perimeter collects water and directs it to a sump pump. It prevents standing water and damp conditions, addressing surface water (from downspouts and runoff) and groundwater that pushes up from below.
- Sump Pumps: A properly installed sump pump keeps water from pooling and prevents flooding, especially during heavy rain.
- Vapor Barriers: Installed on walls to reduce moisture and prevent mold growth.
- Arteries for Cracks: A proprietary solution that seals cracks and redirects water away, ensuring long-term protection against leaks.
Pros: Cost-effective, non-invasive, highly reliable. Addresses both surface and groundwater issues.
Cons: It doesn’t prevent water from reaching the foundation but manages it effectively.
Our Verdict: For most Maryland homes, an interior drainage system combined with a sump pump and our Arteries for Cracks solution is the best long-term waterproofing approach.
Exterior Waterproofing: Effective, but Limited
Exterior waterproofing is often marketed as a complete solution because it stops most surface water before it reaches your foundation. However, it does not fully address groundwater that hydrostatically pushes up from below.
- Exterior Drainage Systems: Underground pipes divert surface water away from your foundation.
- Waterproof Membranes & Coatings: Applied to foundation walls to prevent seepage.
Pros: Reduces the amount of water reaching basement walls and helps with surface runoff.
Cons: Expensive, disruptive, requires excavation, and doesn’t always prevent groundwater from pushing up into the basement. In rare, severe cases, both exterior and interior waterproofing might be needed, but this is unusual in our region.
Our Verdict: Exterior waterproofing is useful for controlling surface water, but it is not a complete solution for groundwater issues. Interior waterproofing remains the more effective and cost-efficient approach for most homes.
Crack Sealing & Quick Fixes: A Temporary Band-Aid
Many homeowners try sealants, epoxy injections, or waterproof paints as a first step. While they might work short-term, they don’t address the root cause of water intrusion.
- Sealants & Epoxy Injections: Fill cracks in basement walls but fail under pressure when the foundation shifts.
- Waterproof Coatings: Applied like paint to prevent minor moisture intrusion but don’t hold up long-term.
Pros: Inexpensive, easy to apply.
Cons: Temporary, breaks down over time, doesn’t prevent future leaks.
Our Verdict: Quick fixes won’t keep your basement dry. Instead, our Arteries for Cracks system provides a permanent solution by sealing cracks and creating pathways to move water safely away from your foundation.
