Basement & Foundation

OSEAGUARD offers complete basement and foundation waterproofing systems designed to protect underground structures from groundwater infiltration, hydrostatic pressure, and long-term moisture damage.

Basement and foundation waterproofing refers to a complete waterproofing system applied to underground structures to prevent seepage caused by groundwater, soil moisture, and hydrostatic pressure. Unlike above-ground roof systems, basement waterproofing must address the following issues:

Continuous soil contact

Water pressure in the surrounding soil

Crack movement and structural settlement

Basement Waterproofing Systems are classified by installation method:

External Waterproofing System: Applied to the outside of foundation walls, most effective against groundwater, suitable for new construction projects, and the most recommended underground waterproofing method internationally.

Internal Waterproofing System: Installed from inside the basement, used when external access is limited, usually in conjunction with drainage solutions.

Pre-coated Waterproofing System: Installed before concrete pouring, the membrane bonds to the poured concrete, preventing water migration between the membrane and the structure. Very commonly used in high-end underground projects.
