But what to do to those who have a brick monolithic structure? This problem can be solved on its own. To do this, pour a new foundation. Digging parallel to the old foundation with a trench, and the depth should be the same as the old foundation. We drive every 25 cm reinforcement for a bunch of old and new foundation. If there are chips and cracks on the old foundation, they must be additionally cleaned of “curly” and expanded so that after everything is poured with concrete solution. Adding a reinforcing grid will add strength to your future foundation, and it will last you another hundred years!
