Wasps have signed former International Rugby Board Young Player of the Year Pat Barnard from Northampton.
Barnard is being tipped as a future England international
Although capped by South Africa at U21 level, the prop qualifies for England through his mother and has already been called into the England Saxons squad.
"By signing Pat we have now finalised our stable of props, all of whom are qualified to play for England," said Wasps' forwards coach Craig Dowd.
Barnard has agreed a two-year contract at Adams Park.
Dowd added: "We've signed him as competition for Phil Vickery, not cover for him."

Dowd said the arrival of the 26-year-old should give them the strength in depth to compete against their biggest European rivals.
"The likes of Leicester Tigers and Stade Francais have world class front rows, and with the players we now have on our books, we will be fast moving towards a similar position," he said.
"It is an exciting and competitive group, and they reflect all levels of the game, from the young up-and-coming player in the Academy to the fully fledged international.
"Therefore, I think we could well expect to see England's selection at prop for the next ten years to come from the Wasps stable.
"In my mind, Pat is a future England tight head prop and in his time at Northampton, he has proved himself as one of the best scrummagers in the Premiership."
