An interior perimeter drain that collects water at the footing and sends it to a sump pump.
When digging outside is impractical, because of a driveway, a neighbour's house a metre away or a finished landscape, water can be managed from inside. The slab is cut along the wall, a drain is laid beside the footing and the trench re-poured.
The drain runs to a sump pit with a pump sized for the house. A battery backup is worth adding in Ottawa, where the worst storms often knock the power out.
