Our foreman Willie installing a new poured wall stairwell entry.
This house had problems with bouncy and sagging floors. We installed three SmartJacks with galvanized steel beams to help carry the load of the joist. First we dig holes in the floor and filled them with crushed stone to provide a base for the SmartJacks. Then we install the jacks with 8 foot long galvanized steel beams. This solved the problem. The floor is nice and sturdy.
