| COMPARE | INTEGRISCAN™ | FLOOD TESTING |
|---|---|---|
| METHOD |
New Dual-Sensor Cross Scan Technology (Proprietary) |
Gravity – water is temporarily dammed over a horizontal surface to determine the effectiveness of the waterproofing. Visual inspection for moisture intrusion. |
| TESTING DEVICE |
IntegriScan utilizes a mobile platform that isolates a smaller test area for better conductance and more reliable readings |
All downspouts are blocked, water sits on the roof for 24-48 hours. Visual inspection for moisture intrusion. |
| COVERAGE |
The scanning platform and vertical roller are used in conjunction to test all areas including horizontals, verticals, transitions and details |
Flooded horizontal surfaces only |
| TEST INVERTED ASSEMBLIES |
YES |
Will indicate (but not find) only obvious leaks, will not pinpoint breaches. Hydrostatic pressure is a factor. |
| TEST CONVENTIONAL ASSEMBLIES |
YES, with TruGround® installed directly below the membrane |
Flood testing of a conventional roof is typically not possible due to structural stress. |
| TEST EPDM | YES – ONLY Detec Systems can test black EPDM and semi conductive waterproofings. | NO – Flood testing is not recommended due to structural stress. |
| TEST VERTICAL SURFACES | YES – Detec’s Vertical Scan Unit (VSU) is a belt mounted roller apparatus that will detect breaches in verticals. | NO |
| TEST TIME | Typically 5,000 sq ft/hr | 1 day to construct dams and 24-48 hours to test |
| ACCURACY |
Pinpoints locations of water ingress |
Extrapolation from location of interior leak |
| RCABC ROOFING GUARANTEE PROGRAM | APPROVED | NOT APPROVED |
