Foundation Damage needing repair or replacement

When a Foundation Fails, Replacement Might Be the Only Option

Cracks, sinking floors, water intrusion — if your home or building’s foundation is severely damaged, repairs may no longer be enough.

In some cases, the entire foundation needs to be replaced from the ground up.

At Construction Solutions, Inc., we specialize in foundation replacement for residential and commercial structures throughout the New England region.

Whether due to age, poor drainage, or improper original construction, we know how to remove and rebuild a foundation safely and correctly — all while protecting the structure above.

When Does a Foundation Need Full Replacement?

While minor issues can be solved with crack repair or partial reinforcement, foundation replacement is typically required if:

  • The foundation is crumbling or spalling
  • There’s severe settling or shifting
  • Water damage has destroyed structural integrity
  • The original foundation was improperly installed
  • You’re adding a second story that exceeds structural load
  • The home was built on a non-code or makeshift base (like stones or blocks)

Step-by-Step: How a Foundation Is Replaced

Replacing a foundation is a major construction project — but with the right crew and plan, it can be done efficiently and safely.

Here’s how we do it:

1. Initial Assessment & Engineering

We begin with:

  • A structural assessment
  • Soil testing (if needed)
  • Engineering and permit coordination
  • Utility location and safety planning

Your town or city may also require specific foundation design specs.

2. Shoring & Lifting the Structure

To replace the foundation, we need to support the structure above it. This involves:

  • Installing temporary steel beams and cribbing
  • Lifting the building (often just inches) off the foundation
  • Securing it to remain stable during work

In some cases, we can work without full lifting, especially for partial replacements or additions.

3. Demolition of the Existing Foundation

Next, the old foundation is:

  • Jackhammered or excavated out
  • Debris removed with vac trucks or heavy machinery
  • Sub-base graded and compacted for the new pour

We often use vacuum excavation to safely remove soil in tight or delicate areas without damaging underground utilities.

4. New Foundation Construction

We build your new foundation to modern code and with improved durability:

  • Footings are dug and poured
  • Foundation walls are formed and reinforced with rebar
  • Concrete is poured, cured, and inspected
  • Waterproofing and drainage systems (like footing drains or sump pumps) are installed

You can also choose to add height, bulkhead access, or a full basement during this step.

5. Lowering and Reconnecting the Structure

Once the new foundation is cured:

  • The structure is carefully lowered back into place
  • Plumbing, electric, HVAC, and utilities are reconnected
  • Interior finish work can begin (floors, stairs, etc.)

6. Final Inspection and Backfill

We complete:

  • Backfilling with clean soil or gravel
  • Grading and site restoration
  • Final inspection and sign-off by local building authorities
