Our Exterior Basement Waterproofing Process
To waterproof your exterior basement walls, we begin by excavating the soil surrounding your foundation. This process might look extensive, but it is necessary for thorough protection. Here’s what you can expect:

1
Excavation and inspection of your foundation to assess any existing damage.
2
Application of high-quality exterior waterproof membranes.
3
Installation of weeping tile to redirect water away from your home.
4
Optimizing drainage systems to prevent water from accumulating around your foundation.
5
Final inspection of waterproofing integrity and backfilling.
Why Exterior Basement Waterproofing is Important
Exterior waterproofing tackles water before it can even reach your foundation. While interior waterproofing can seal cracks and prevent moisture buildup inside, it doesn’t address the challenges that wet soil, rain, or snowmelt can bring. Without exterior protection, water can still penetrate cracks and cause leaks.
Exterior basement waterproofing protects your foundation from water, moisture, and hydrostatic pressure buildup, reducing the likelihood of cracks and leaks.
Waterproof Membrane Application
Mersey Heating and Air Conditioning’s experienced technicians will first repair any foundation cracks with a specialized waterproof sealant. Next, they’ll apply premium-quality sealants and waterproof membranes to keep groundwater and moisture from affecting your foundation.
Weeping Tile Repair and Installation
Our team will inspect your existing weeping tile system to determine if replacement is necessary. If required, we will install new weeping tile to efficiently redirect groundwater away from your foundation, reducing hydrostatic pressure and the risk of cracking or seepage.
Drainage Improvements
Drainage problems can lead to water pooling around your foundation. Our skilled plumbers and landscapers will re-grade the areas surrounding your home and enhance the exterior drainage to ensure that water does not collect near your foundation.
Never question your foundation’s integrity again!
