The Dutchman who had a brief spell at Sheffield United at the end of last season, has signed a two-year deal at Blundell Park.
Cas was offered a deal at Bramall Lane, but rejected it to look for a more long-term deal.
The 31-year-old becomes Paul Groves's second signing of the summer following the capture of Tony Crane from Sheffield Wednesday as he looks to assemble a squad capable of winning promotion back to Division One next season.
