Goodwill Disclosure [Text Block] | Note 7 - Goodwill All identifiable goodwill as of October 31, 2025 and January 31, 2025, is attributable to the purchase of the remaining 50% interest in Perma-Pipe Canada, Ltd., which occurred in 2016. The Company performs an impairment assessment of goodwill annually as of January 31, or more frequently if triggering events occur that could indicate that it is more likely than not that the fair value of the reporting unit did not exceed its carrying value, resulting in an impairment. The following table provides a reconciliation of changes in the carrying amount of goodwill:
|  | January 31, 2025 |  |  | Foreign exchange change effect |  |  | October 31, 2025 |
Goodwill |  | $ | 2,057 |  |  | $ | 71 |  |  | $ | 2,128 |
There were no triggering events identified during the three and nine months ended October 31, 2025.
