Interior Waterproofing
Stop leaks, control moisture, and protect your building from the inside out.
What Is Interior Waterproofing?
Interior waterproofing manages water that has already made its way inside a structure by directing it away safely. For commercial properties, this often includes:
Drainage Systems – Installing interior drain channels along the footing to capture water and move it away from occupied spaces.
Sump Pump Systems – Collecting and pumping out water from basements or underground areas to keep them dry.
Wall Treatments & Sealants – Applying waterproof membranes or coatings to block seepage and moisture penetration.
Humidity Control – Installing commercial-grade dehumidifiers to prevent mold, mildew, and air quality issues.
Together, these solutions protect both the structure and the people inside it.
Why It Matters for Commercial Properties
Interior waterproofing protects against:
Property damage caused by recurring leaks or groundwater pressure
Tenant disruption from wet or unsafe spaces
Mold growth that leads to health concerns and liability issues
Structural damage from long-term water exposure
By controlling water inside the structure, interior waterproofing extends the lifespan of your building and reduces future maintenance costs.
