Ostanes Engineering has identified poor drainage and ground conditions as significant factors in the recurring internal cracks of a low-set brick veneer home. The engineering firm’s investigation, prompted by the reappearance of a hallway crack after a previous repair, highlighted issues such as standing water and saturated soil around the property.
The inspection took place during rainy and cloudy weather and revealed several problematic signs, including hairline cracks around window and door frames, a prominent crack in the hallway, and exposed slab edges. However, no substantial cracking was detected on the home’s external brick walls. Standing water was observed pooling beside the property and throughout the yard, raising concerns about inadequate surface drainage. This was deemed the primary structural serviceability issue, with moisture changes near the footing zone potentially contributing to seasonal ground movement and damage to internal finishes.
Ostanes Engineering’s assessment was based on a visual inspection, without conducting excavation, footing exposure, level surveys, geotechnical investigations, plumbing tests, or removal of internal finishes. Due to these limitations, the inspection could not definitively determine the cause of the recurring hallway crack. The firm recommended engaging a licensed plumber or experienced drainage contractor to enhance surface water management and suggested reviewing ground levels near exposed slab edges. If these measures prove insufficient, subsurface drainage might be considered.
Importantly, Ostanes Engineering advised against immediate cosmetic repairs before addressing the drainage issues. For the affected property, cosmetic work was recommended only after drainage improvements and an observation period of six to twelve months. Instead of another surface patch, a local replacement of the damaged hallway plasterboard section was suggested. Further engineering assessment was advised if existing cracks widened, reopened, or if new cracks emerged, especially 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 property details, photographs, previous reports, and histories of the problem to establish an appropriate inspection scope. This proactive approach is intended to ensure that underlying issues are addressed to prevent further damage to residential properties.
