The Importance of Regular Inspections

Car parks endure heavy traffic and loads, making it essential to regularly inspect and maintain the concrete floor slabs to prevent deterioration. Continuous exposure to vehicles, especially heavy ones, can cause significant wear and tear over time. Regular inspections help in identifying potential issues early, ensuring the safety and longevity of the car park.

Sub-surface Voiding: A Hidden Threat

Sub-surface voiding can occur beneath concrete floor slabs for various reasons, including soil erosion, water infiltration, and natural settlement. These voids can compromise the structural integrity of the slabs, leading to cracks, uneven surfaces, and even potential collapse if left unaddressed. Detecting these voids early is crucial to prevent severe damage and costly repairs.

Void Detection Using Ground Penetrating Radar (GPR)

Ground Penetrating Radar (GPR) surveys offer a non-intrusive, efficient means of inspecting concrete floor slabs in car parks. GPR works by emitting radar pulses into the ground and analysing the reflected signals to create a detailed image of the subsurface. By scanning on a regular grid, GPR can detect construction details, identify defects, and assess the overall condition of the slabs. This method is highly effective in locating voids, cracks, and other anomalies without causing any damage to the structure.

Benefits of GPR for Concrete Slab Inspection

Using GPR for inspecting concrete floor slabs in car parks offers several benefits:

  1. Non-destructive: GPR does not require drilling or coring, preserving the integrity of the concrete slabs.
  2. Accurate: GPR provides precise information about the location and size of voids and defects.
  3. Comprehensive: GPR can cover large areas quickly, offering a thorough assessment of the entire car park.
  4. Cost-effective: Early detection of defects helps in planning timely repairs, reducing long-term maintenance costs.

Detection of Defects in Car Park Slabs

Our GPR surveys can identify voids, cracks, and other defects in concrete floor slabs, allowing for timely repairs and maintenance, thus extending the lifespan of the car park. The process involves scanning the concrete surface with GPR equipment, which detects variations in the subsurface materials. This information is then used to identify areas of concern, such as:

  1. Voids: Spaces beneath the slab that can cause it to sag or collapse.
  2. Cracks: Structural fractures that can lead to further deterioration if not addressed.
  3. Delamination: Separation within the slab layers that can weaken the structure.
  4. Rebar Corrosion: Detection of corroded reinforcing bars that can compromise the slab’s strength.

Comprehensive Survey Deliverables

We provide comprehensive reports and CAD drawings detailing the findings of our GPR surveys, highlighting any detected defects and areas requiring attention. Our deliverables include:

  1. Detailed Reports: These reports summarise the survey results, describing the location, size, and nature of any detected defects.
  2. CAD Drawings: Accurate drawings that map out the defects, providing a visual representation of the slab’s condition.
  3. Recommendations: Based on the survey results, we offer recommendations for necessary repairs and maintenance to ensure the slab’s integrity.
