It’s important to see both the exterior and interior areas when inspecting for foundation cracks. If there is evidence of cracks on the interior wall beneath the exterior grade, this may mean that the foundation crack itself will need to be repaired.

It is common for older homes and buildings to settle over time due to soil erosion. Poor drainage can lead to foundation cracks. It is important to grade the soil away from the walls.

Downpipes which carry rain off the roof are located to exit away from the foundation wall, a distance of five feet. It is important to make sure that the drainage pipes are in good shape and that the downpipes are clear from obstructions.

Water-proofing work can be completed once the parging is done. Restoration of weeper /drainage systems and installation of drainage aggregate can be done as part of the process.
