What Drives Waterproofing Needs in Uniondale, NY

Why Uniondale, NY Properties
Develop Water Problems

Waterproofing isn't one-size-fits-all. What works in one climate and soil type can be completely wrong for another. Our crews understand the specific conditions that drive water problems in Uniondale, NY — and in Uniondale specifically.

Rainfall, Storms & Seasonal Moisture in Uniondale, NY

Uniondale, NY experiences weather cycles that regularly saturate the soil around foundations — and when soil around a foundation gets saturated creates conditions that drive water through even hairline cracks. The process is cumulative — but the damage it causes get more expensive the longer they continue.

The Uniondale area has its share of heavy rainfall periods that push sump pumps to their limits. Residents in this part of NY often know from experience that a hard rain season usually mean a wet floor.

Foundation Types Common in Uniondale, NY Properties

The soil type common in this part of NY directly determines how water behaves near foundations. Clay-heavy soils, common in many Uniondale, NY communities, build up hydrostatic pressure that cracks and infiltrates even solid concrete over time. Understanding what you're dealing with underground changes everything about what solution will actually work.

Uniondale and surrounding Uniondale, NY communities have a wide range of housing ages and foundation types. Properties built decades ago throughout Uniondale often lack adequate below-grade moisture protection. Our Uniondale, NY technicians are familiar with every foundation type common in this area.
