Basement Waterproofing with Polyurea
A wet basement is not fate. Duayen performs professional basement waterproofing with 100% original polyurea - a continuous, flexible layer that blocks moisture, groundwater and water intrusion - with GRACO equipment and up to 10-year written warranty.
When Do You Need Basement Waterproofing?
Basement dampness usually comes from a few causes - and we handle all of them:
Groundwater & External Water Pressure
Water entering through walls and floors from groundwater pressure or rainwater absorbed in the soil.
Cracks in Concrete & Joints
Cracks and casting joints that let water seep through - sealed and stabilized before spraying.
Mold & High Humidity
Basements with mold and musty smell - after sealing, the basement stays dry and fully usable.
Foundations & Underground Walls
Sealing of foundations and external walls that prevents moisture intrusion during construction or renovation.
Why Polyurea for Basement Waterproofing?
Complete Water Barrier
A seamless, joint-free layer that leaves no weak points for moisture intrusion.
Withstands Constant Dampness
Polyurea bonds strongly to concrete and holds up even under constant moisture and humidity.

Most basement waterproofing jobs finish within a few days - no unnecessary excavation.
Durability for Years
With a written warranty of up to 10 years and a basement that stays dry even through hard winters.
