What Makes Andover & Andover, MN
Properties Vulnerable to Moisture

Waterproofing isn't one-size-fits-all. A solution designed for one foundation design can be completely wrong for another. Our crews understand the specific conditions that drive water problems in Andover, MN — and in Andover specifically.

Rainfall, Storms & Seasonal Moisture in Andover, MN

Andover, MN sees weather conditions that create real, recurring pressure on below-grade structures — and the hydrostatic pressure that builds against foundation walls works into structures through any pathway available. The process is cumulative — but the structural consequences compound every wet season.

The Andover, MN communities like Andover regularly deals with serious storm events that overwhelm drainage systems. Homeowners in Andover, MN have learned the hard way that certain storms usually mean a wet floor.

Soil Conditions & Foundation Types in Andover, MN

The soil type common in this part of MN directly determines how water behaves near foundations. Clay-dominant ground conditions, which are prevalent throughout much of MN, build up hydrostatic pressure that cracks and infiltrates even solid concrete over time. Understanding what you're dealing with underground is step one of any credible waterproofing diagnosis.

Andover and surrounding Andover, MN communities have a wide range of properties spanning decades of construction. Structures predating modern waterproofing codes regularly show the kind of slow-developing moisture problems that only become visible after significant damage has already occurred. The SJ Waterproofing Pros crew serving Andover are familiar with every foundation type common in this area.
