Ostanes Engineering has raised concerns about inadequate drainage systems contributing to recurring cracks in residential properties, following an investigation into a low-set brick veneer home. The structural inspection revealed significant internal cracking, standing water, and saturated soil around the property, highlighting drainage issues as a primary concern.
The inspection was requested after a hallway crack reappeared post-repair. Ostanes Engineering examined accessible areas during inclement weather, identifying hairline cracks around windows and doors, prominent hallway damage, gaps along cornices, and exposed slab edges. External brick walls showed no significant cracking.
Key observations included surface water pooling around the property and saturated ground conditions, pointing to inadequate surface drainage as a significant concern. The report suggested that moisture changes near the footing zone might contribute to seasonal ground movement, affecting internal finishes. However, the inspection did not establish a confirmed mechanism for ground movement, and the recurring hallway crack could not be fully diagnosed based on its visible width alone.
The assessment, limited to a visual inspection, did not include excavation, footing exposure, level surveys, or plumbing tests. These limitations mean that visible symptoms may not fully reveal underlying causes. The report recommended hiring a licensed plumber or drainage contractor to enhance water management, reviewing ground levels near slab edges, and considering subsurface drainage if necessary. Cosmetic repairs were advised only after drainage improvements and a six to twelve-month observation period, with the damaged hallway plasterboard suggested for local replacement.
Further engineering assessment was recommended if cracks widened or new ones appeared, particularly if accompanied by sticking doors or visible building distortion. Ostanes Engineering offers structural crack and movement inspection services through its website, allowing homeowners and property managers to submit relevant details and photographs to establish an appropriate inspection scope.
