BlindSide Spark DC is an Android field aid for ELD and EFVM holiday survey work across blindside waterproofing, roof and deck membrane, underslab sheet, tank liner, containment liner, and coating jobs.

Set the voltage. Check the grounding setup. Drop each holiday on the map. Patch it, re-test it, and block cover release while anything is still open.

What it exports

Field scope

The phone records the survey field aid. It does not detect leaks, measure thickness, measure voltage, or certify the surface. Confirm every setpoint against the membrane maker instruction, project spec, inspector, and local rules.

FAQ

What is the main job?

Set the right ELD survey voltage for the membrane mil, map every holiday open or patched, and export a survey package for cover release.

Does it work without an account?

Yes. There are no accounts and no backend. The local project record stays on the device unless you share or export it.

Can it replace the detector?

No. It is a field aid for a calibrated holiday detector and the project spec.
