Exterior Waterproofing in Troy MI

Foundation Protection

Professional Exterior Waterproofing in Troy, MI

Troy is the largest city in Oakland County with over 90,000 residents, and most of its homes were built between the 1960s and 1980s on heavy clay soil that holds water against foundations for days after a rainstorm. Those 40 to 50 year old foundations were sealed with basic tar coatings that are now cracked and failing, leaving nothing between your basement and thousands of gallons of groundwater every spring. Mansour’s Innovations provides exterior waterproofing built specifically for Troy’s aging housing stock, stopping water permanently at the source before it ever reaches your basement.

How We Protect Troy Foundations From the Outside

Our process starts with full foundation excavation, followed by professional grade waterproof membrane application, drainage tile installation, and proper regrading to direct water away from your home. For Troy homeowners dealing with water intrusion that keeps returning every spring regardless of interior fixes, exterior waterproofing is the only permanent solution that addresses the root cause and protects your foundation from long term structural damage and mold.

Frequently Asked Questions

Exterior waterproofing in Troy typically costs between $8,000 and $15,000 or more depending on the size of your foundation and the scope of the project. While it costs more upfront than interior solutions, it provides the most comprehensive protection by preventing water from ever reaching your foundation walls in the first place. For Troy homeowners dealing with severe or persistent water problems that keep coming back every spring, exterior waterproofing is often the most cost effective long term solution when you factor in the repair costs it prevents down the road.

Exterior waterproofing is recommended when you have severe or persistent basement water problems, visible exterior foundation cracks, deteriorating foundation walls, high water table issues, or when interior waterproofing has proven insufficient. It’s also the best choice during new construction or major renovations when the foundation is already exposed.

Yes, exterior waterproofing requires excavation around your foundation, which will temporarily impact landscaping, shrubs, and any hardscaping near the foundation. However, we take great care to protect your property and restore everything to its original condition (or better) after completion. We can also work with you to minimize disruption to valuable landscaping elements.

Most exterior waterproofing projects take 5-10 days to complete, depending on foundation size, soil conditions, and weather. This includes excavation, waterproofing application, drainage installation, backfilling, and restoration. We work efficiently while maintaining high quality standards, and we’ll provide a detailed timeline during your consultation.

Exterior waterproofing provides permanent protection against water intrusion, prevents foundation deterioration, eliminates chronic basement moisture problems, increases property value, and protects your home’s structural integrity. It also reduces the risk of mold growth, improves basement air quality, and can lower insurance premiums. Most importantly, it provides peace of mind knowing your foundation is fully protected.
