my house was built in 1900. it has a brick foundation. The brick is now moist and I want to waterproof it. I got 3 different types of quotes:
1- Bitumin exterior waterproofing with gravel replacing soil and grading
2-Praseal exterior waterproofing with gravel replacing soil and grading
3- Mirror drain with no sealant
What is the best method to keep the brick foundation dry?
