Methods for Splicing Underground Electrical Cables

Electrical Question: How are underground electrical power cables spliced?

We have an underground power cable network. We used some cable splice kits for jointing the under ground power cables, however, they did not work. Now the contractor is suggestion to use resin filled cable joint kits. Kindly give me a reference of NEC regarding splicing of under ground power cables i.e. under which NEC code we should use resin filled splicing kits for jointing under ground power cables.

Please note that we are using medium voltage.
