A two story house, inverted with bedrooms and utilities in the lower level. No basement as such. The house backs on Muskoka granite and a hill, with a fair amount of seepage along this hill. The house is 28 ft by 40 ft as the " main slab ". Rear 40 ft. wall is 5 ft below grade, front 40 ft wall is 3 ft below grade. Only the two 28 ft. ends are accessible to dig. A large garage and office is at grade level. With the seepage water in the area are birch, oak or maple tree roots a problem with drainage tile? We are of the opinion that hardwood trees are not?
Answer:
Any tree's roots are going to be a problem for drainage tile. The only difference with fast growing trees is that roots are more plentiful to help feed the fast growth. Fast growing trees also have more massive root systems as one would expect.
