Welcome to the world of basements!
You will need to think about the mature size of the hedge and plant accordingly. Too close to the house and you will have some potential issues with siding and windows.
Contrary to popular belief, roots do not really cause damage to sound foundations. Roots need space to grow (and oxygen and water to survive). They will not break into concrete foundations or sewer pipes. They can exploit openings, but will not break in.
There are products designed to serve as barriers to roots and if you are concerned about the waterproofing or if you think the foundation is cracked. Proper installation is crucial as roots can grow over or under improperly placed barriers.
To find products and where to buy them, just do an internet search for “Tree root Barriers.” Please let me know if you have any additional questions and feel free to email me for more information.
