Inspection and Observations

‍
Our engineers inspected the concrete deck. These inspections consisted solely of the Electric Field Vector Mapping (EFVM) test. The test was performed by using the Detec IntegriScan System following the ASTM Standards and were thoroughly executed throughout the entire deck with particular attention to all exposed and visible areas of the concrete.

The test was performed by using the Detec IntegriScan System following the ASTM Standards:

• E 241 - Standard Guide for Limiting Water-Induced Damage to Buildings.
• E 2128 - Standard Guide for Evaluating Water Leakage of Building Walls.
• E 2266 - Design and Construction of Low-Rise Frame Building Wall Systems to Resist Water Intrusion.
• D 7877 - Electronic Methods for Detecting and Locating Leaks in Waterproof Membranes.
• D 8231 - Use of a Low Voltage Electronic Scanning System for Detecting and Locating Breaches in Roofing and Waterproofing Membranes.
  ‍

Overall, the waterproofed concrete deck is in good condition. The EFVM test confirms waterproofing membranes are free of breaches, holes, or seam voids during construction. Regarding specific observations and conditions observed during our inspection of the seawall, these are as follows.

• Active leaks beneath the waterproofing membrane were detected in three locations at the northwest ends of the deck. See Figure 1 thru 4.

Conclusion

‍
We completed our inspection and investigation of the exterior waterproofed concrete deck located at 347 Don Shula Dr., Miami Gardens, FL 33056. The waterproofed concrete deck is in good condition. Instances where there are active leaks in existing deck, the waterproofing membrane should be patched, cleaned, and sealed. This is recommended for the areas shown in Figures 2 thru 4.
