- What Is Exterior Waterproofing?
Your First Line of Defence Against Water Intrusion
Exterior waterproofing stops water before it ever reaches your basement walls.
Exterior waterproofing involves excavating around your home’s foundation, sealing it with advanced membranes, and installing drainage systems to redirect water away. It’s the most effective long-term solution for homes dealing with persistent leaks, high water tables, or exterior foundation cracks.
DrySeal uses professional-grade tools and materials to deliver lasting results — guaranteed.
- Signs You Need Exterior Waterproofing
Outside Water Issues Lead to Inside Damage
If these signs appear, exterior waterproofing may be the best solution.
Water seeps in through foundation walls when the soil around your home becomes saturated. Watch out for:
Foundation cracks visible from the outside
Wet basement corners or walls
Mold or mildew near exterior walls
Peeling paint, efflorescence, or white residue inside
Wet basement corners or walls
