By ground

Three kinds of ground, three kinds of wet basement

Caledon climbs from 221 m at its lowest point to 485 m at its highest. Where a house sits decides how water reaches it.

The escarpment side

Caledon Village · Alton · Cataract · Belfountain · Inglewood · Cheltenham · Terra Cotta

Villages along Hurontario Street and the Credit River, on and below the Niagara Escarpment. The ground is sand, gravel and fractured limestone over shale, so it drains fast; basements here get water from grading and downspouts, from springs on sloping lots, and from a water table that rises in spring. Many of the houses date from the 1800s with fieldstone foundations. Most lots are on wells and septic, with municipal wells in Caledon Village, Alton, Inglewood and Cheltenham.

The moraine side

Caledon East · Palgrave · Mono Mills · Albion · Mono Road · Sandhill

The Oak Ridges Moraine: rolling sand and gravel hills with pockets of silt and clay between them, the source of the Humber. Estate lots on wells and septic, and Caledon East on municipal wells. Water here moves sideways along a clay layer and appears at one wall only, so the assessment maps which wall sits against the clay before any repair is named.

South Caledon

Bolton · Mayfield West · Tullamore · Wildfield · Macville · Valleywood

The Peel Plain: flat farmland and the newest subdivisions, on fine clay till that holds water against the wall for weeks after a storm. Poured concrete foundations, shrinkage cracks, saturated backfill at the floor-wall joint, and sanitary sewers in Bolton, Caledon East and Mayfield West that can back up in a storm, which is where the Region of Peel backwater valve rebate applies.

Village houses

Historic centres of every village and hamlet

Brick and frame houses from the 1850s to the 1920s on small lots, with stone or early block foundations, no footing drain, and additions whose foundations meet the original at a joint that leaks. Side yards are narrow, so interior drainage and hand-dug trenches are common.

Water around Caledon

Two rivers, one escarpment, one moraine

The Credit River starts above the Niagara Escarpment near Orangeville and cuts through Cataract, the Forks of the Credit, Belfountain, Inglewood and Cheltenham on its way to Lake Ontario, 90 km later at Port Credit. The Humber starts on the Oak Ridges Moraine near Palgrave and Mono Mills. Credit Valley Conservation manages the western watershed; the Toronto and Region Conservation Authority manages the Humber side. Streets near either river and its tributaries sit closer to the water table than the uplands between them.

The red shale exposed at the Cheltenham Badlands is the same Queenston shale that lies under the clay of south Caledon. It is almost impermeable, which is why water that reaches a foundation on the Peel Plain has nowhere to go but sideways, into the wall.
