Bur Oak Ave in Markham
One exterior facing basement wall is allowing water to pour in when heavy rain fall (e.g. Sunday July 16th). The basement floor is still damp in one area. We are unable to find the source--tried a few fixes but only worked temporarily and not against heavy rainfall. Downspout was routed towards the driveway/away from the house and buried under the lawn. Would like an estimate on waterproofing from the exterior. It is a townhouse and the wall is approximately 15 feet wide.
