Is it true that Wisteria can grow underneath foundations and cause them to lift? How far do the roots travel?

i planted a wisteria against my brik garage which is attached to the house about 20yrs ago.it's very vigorous, so I cut it back now every other year, but never seen any damage to brickwork, tho' it goes through the roof, had to trim it inside!
