In How It's Done Posted

Underpinning has two essential benefits. First, it creates added height to your existing foundation, which in turn adds 100% usable living space to your basement. Second giving your home an added selling feature for re-sale and increasing the value of your home.

Benefits of Underpinning

When is underpinning necessary?

1. It is either necessary to stabilize structural problems that have developed
2. Create 100% more of living space for personal use or for renting.

Foundation wall underpinning becomes a necessity when the existing foundation is shifting so dramatically and substantially that it is unable to safely support the house above it. In most cases the original supporting construction is inadequate. All or part of the original foundation is resting on marginal land with a bearing capacity insufficient to hold up the structure.
In other case damage done to the structural integrity of the foundation by unknowledgeable tradesmen. You will see signs including bowing of walls, sinking, bulging or sagging, structural cracks, and discrepancies in the alignment of windows and doors. Strategic Homes Group Inc provides professional assessment and engineering drawings to fix the damage done, promptly before further damage or loss of investment occurs. Underpinning the foundation walls stabilizes the home and gives increased strength to the building.

We have time testes certified structural engineers who will provide required Shoring, Underpinning drawings, site visits and certified report once the project is finished.

“Don’t take any chances or cut corners and make sure the company you choose to do the work has underpinning and liability insurance.”
