Waterproofing
White residue on basement walls
If your basement flooded once, it can happen again. We offer complete flood prevention and waterproofing solutions to ensure your basement stays dry permanently.
What causes white residue on basement walls?
Concrete and mortar are highly porous materials naturally packed with natural minerals. When water from the saturated ground outside dissolves these minerals, it carries them right through the foundation wall, evaporating on the inner surface and leaving the heavy salt crystals behind.
Sustained rainfall forces water against the exterior basement walls, dissolving the internal salts and minerals naturally present within the concrete or the surrounding soil.
Driven by lateral pressure, the mineral-rich water flows through the microscopic pores of the masonry blocks. As the moisture hits the dry basement air, it evaporates, leaving a crusty salt deposit.
When these salt deposits crystallize inside the concrete pores, they expand massively. This internal pressure shatters the concrete bonds from within, making your foundation walls flake, scale, and weaken over time.
