Light bulb moment

Nick Dyachenko is an electrical contractor. He discusses a job where a brand-new heating cable installation had to be replaced due to damage during concrete operations.

Imran Kahn reviews a hot applied waterproofing failure where the waterproofing was bonding well during morning application, but failing during afternoon application within the same day. The eventual cause became apparent only after several other jobs exhibited the same phenomenon.
