A city born in 1957 to keep one corporation.

New Canada Township and the town hall on Lake Phalen.

For nearly a hundred years, the land that became Maplewood was part of New Canada Township— agricultural, lightly populated, organized in 1858. In 1879 the township built a more centrally-located town hall near the north shore of Lake Phalen. The settlement pattern was farms and small homesteads spread across Ramsey County's glacial till, with the lake and creek corridors serving as the natural focal points.

What survives of that pre-suburban era is a thin scattering of pre-1900 stone and brick foundations near Phalen and the older roads. Most of them have been freezing and thawing for 120+ winters.

Lake Phalen and the till around it.

Maplewood sits on glacial till — the unsorted mix of clay, silt, sand, and gravel left by the retreating Wisconsin glacier across Ramsey County. The clay content holds water against foundations, and the embedded sand and gravel pockets transmit it unpredictably. The clay-bowl effect— where loose backfill around a foundation traps water against the wall while the dense till around it can't drain — is the most common failure mode in Maplewood basements.

Lake Phalen sits on the south end of the city, and the properties around it deal with a perched water table that comes up to slab elevation every spring. The same is true for the smaller water bodies and creek corridors throughout Maplewood — Battle Creek, Beaver Lake, Wakefield Lake, Carver Lake.

3M and the 1957 incorporation.

In 1955, 3M built its Central Research Laboratory on 150 acres along Highway 12 in New Canada Township — just outside the city limits of Saint Paul. Saint Paul almost immediately began making noises about annexing the area for the additional tax revenue. New Canada Township residents responded by voting to incorporate as the Village of Maplewood on February 26, 1957, by a margin of five to one. The village had a population of 14,200 at incorporation. Waldo Luebben was the first mayor.

The reason this matters for waterproofing is that the boundary lines drawn in 1957 produced a city that surrounds Saint Paul on three sides in an unusual horseshoe shape. Maplewood's housing stock looks similar to neighboring Saint Paul on every block — same eras, same builders, same foundation types — but its drainage infrastructure was built and maintained by a separate municipality the entire time.

The post-war rambler wave.

Between the end of World War II and the mid-1960s, most of central and northern Maplewood filled in with the standard post-war product — small one-story ramblers and minimal-traditional starter homes, mostly on cinder block foundations. The original drain tile was a single perforated pipe at the footing. Exterior dampproofing was a thin tar coat. Grading was whatever the bulldozer left. Those homes are now sixty to seventy years into a useful life that was designed assuming twenty, and they sit on the same till as their century-old neighbors a block over.

Maplewood Mall and the freeway era.

Maplewood Mall opened on 125 acres in 1974, anchoring the commercial north side. St. John's Hospital opened in 1985. Highway 36 and I-694 turned the city into a freeway-threaded suburb, and the 1980s through 2000s filled in the remaining lots with poured-concrete homes on the same till — sometimes on the lower or wetter properties that earlier eras had passed over.

Why Maplewood basements leak today.

A Maplewood leak is usually one of three stories:

1. Pre-1900 stone or brick home near Phalen or the older roads. Lime mortar crumbling, perched water table, century of freeze-thaw.
2. The post-war cinder-block rambler. Mortar joints failing, drain tile silted, surface grading shifted by every owner since the 1950s.
3. The lake-corridor or newer infill home. Wall is fine. Lake-side water table comes up every spring. Cove joint cracks under hydrostatic pressure.

What this means for your home.

For older Maplewood homes and post-war ramblers, the honest answer is usually a full interior drain tile system with a modern sump. We'll quote that work directly and back it with our lifetime transferable warranty. For newer homes, the high-leverage opening move is usually a sump replacement, a downspout and grading correction, and a flush of the existing tile. Those are obvious contributors worth investigating first — addressing them, depending on your goals for the space, can save thousands and extend the time before a full system is necessary. We'll tell you which.
