Underpinning Mass Pour: This method is the most commonly used. The foundation is excavated in sections to below the footing. Concrete is placed into each pit exposed. This is repeated until the area is completely underpinned.

?As long as there are stable soils, and if it's poured properly, it should be fine. The problem is that in retrofit jobs, often you have very limited space and it's just hard to work in, and that affects being able to pour the concrete right. Also, if the soil is contaminated, you'll need a liner.

You would have to dig and use sacrificial jacks, like car jacks, to hold up the slab from underneath. The footing is taken out in sections as everything else is held up. The footing is formed via rebar with the backend reinforced by dirt. Concrete is then poured from there.

First, the house must be lifted, the ground excavated and foundational support built. Then you must pour a new basement floor and build the basement wall structure. There is also the need to properly waterproof and insulate the basement structure.

Here's a primer on how it works and how to care for it. If you've never seen a house moved before, you might think it's impossible to a new concrete foundation under an existing house. Not only is it possible, but it's probably more common than you might think.

Mass concrete underpinning To transfer the building load safely to the new pin, a dry sand cement packing mortar is rammed in between the new and old foundation. Each 'pin' is typically connected with multiple reinforcement bars, which are driven into the sides of the excavations prior to pouring the concrete.
