The 28-year-old prop joins from Doncaster and has signed a one-year deal.
“I’m looking forward to joining a club that will be buzzing from last year’s success and I’m hoping to add to the squad that the club are putting together,” said the player.
“I can’t wait to get started in November when pre season commences and meeting all the lads.”
Hawks director of rugby Darren Williams added: “Mark has really established himself as a top Championship front row forward and played a major part of Doncaster’s prominent rise into the high echelons of the second tier of the game.
“He is an aggressive no nonsense forward who will provide some grunt and added steel to our forward pack in 2015 which will be needed.”
