Ostanes Engineering has spotlighted drainage issues as a significant factor in the ongoing investigation of recurring cracks in residential properties. A recent structural inspection of a low-set brick veneer home uncovered internal cracking and water accumulation, highlighting the need for improved surface water management.
The inspection, conducted during rainy and cloudy weather, was initiated after a hallway crack reappeared despite prior repairs. Ostanes Engineering’s examination of accessible areas revealed hairline cracks around window and door frames, a more prominent crack in the hallway, gaps along cornices, and exposed slab edges. Notably, external brick walls showed no significant cracking.
Key observations included pooling water beside the property and saturated soil in the yard, pointing to inadequate surface drainage as a primary concern. The report suggested that moisture changes near the footing zone might contribute to seasonal ground movement and internal damage. However, the inspection could not definitively identify a ground movement mechanism or diagnose the recurring hallway crack based solely on its visible width.
Due to the visual nature of the inspection, which did not include excavation, footing exposure, or other in-depth tests, Ostanes Engineering emphasized that visible symptoms might not fully reveal underlying causes. Recommendations included hiring a licensed plumber or drainage contractor to enhance surface water management and reviewing ground levels near slab edges. Subsurface drainage was suggested if surface improvements were insufficient.
The report advised against cosmetic repairs without first addressing drainage issues. It recommended observing the property for six to twelve months after implementing drainage improvements before considering cosmetic work, such as replacing the damaged plasterboard in the hallway. Further engineering assessments were suggested if cracks widened, reappeared, or spread, especially if accompanied by sticking doors or visible building distortion.
