Dublin foundation inspection showing ventilation and structural issues

Foundation Inspection & Structural Assessment in Dublin

A comprehensive inspection of this Dublin residence revealed that the foundation system is in poor condition relative to similar properties. Key issues include an uneven foundation caused by girder beams directly supporting the subfloor, compromised crawl space ventilation due to recent construction, and negative backyard drainage contributing to moisture accumulation.

Blocked ventilation and structural misalignment

The inspection found the crawl space to be in poor condition driven by three main factors: water entry through backyard vents positioned too close to the slab, blocked airflow in the front due to a new step, and negative drainage in the backyard. Structurally, the girder beam directly supports the subfloor, which contributes to the observed uneven floor elevations.

Standard structural inspection methodology

Elevation measurements were taken at key locations throughout the structure to assess floor level variations, identify potential areas of settlement, and document elevation differences for comparison with future monitoring.

A thorough visual inspection was conducted to identify signs of structural movement, material deterioration, moisture intrusion, cracking, and other observable defects. All accessible interior and exterior areas were reviewed based on industry-standard inspection practices.

Standard diagnostic tools were used as needed to further evaluate the condition of building components, ensuring accurate assessment of structural integrity.

Remediation plan for ventilation and stability

To restore the foundation’s integrity, we recommend a multi-faceted approach: improving ventilation by modification of the front yard step or installing replacement vents, repositioning piers to properly align with the structure plate, adding extra piers for stability, and correcting the backyard’s negative drainage to prevent water accumulation.

Restoring structural function and longevity

Promptly addressing these ventilation, drainage, and support issues is critical to preventing costly future repairs. completing these maintenance and repair items will ensure the structural systems perform their intended functions effectively.

Foundation Status
Uneven

Currently influenced by improper girder support and pier alignment.

Moisture Risk
High

Due to blocked vents and negative drainage patterns.

Repair Priority
Urgent

Prompt action needed to prevent escalation of structural damage.

Beyond the Numbers

Improved Ventilation

Restoring airflow by modifying the front step or adding vents to prevent moisture trapping and rot.

Structural Alignment

Repositioning and adding piers ensures the house sits evenly and is properly supported.

Water Management

Correcting negative drainage in the backyard keeps water away from the foundation and crawl space.
