## Overview
Underpinning is the process of lowering your basement floor to increase ceiling height. It involves carefully excavating beneath your existing foundation and extending it deeper into the ground.

## Our Process
1. **Initial Assessment**: We visit your home, assess the existing basement and foundation, discuss your goals, and evaluate feasibility.
2. **Engineering & Design**: A licensed structural engineer produces stamped drawings specifying the underpinning sequence and details.
3. **Permits & Approvals**: We submit permit applications to your municipality and handle all required documentation.
4. **Excavation & Staging**: We excavate in careful sequence, typically in 3–4 foot sections, with temporary supports as needed.
5. **Underpinning Sequence**: New concrete is poured in engineered sequence, extending your foundation to the new depth.
6. **New Slab & Finishes**: Once underpinning is complete, we pour the new floor slab and can continue with finishing if desired.
7. **Inspections & Handoff**: We coordinate all required inspections and provide documentation for your records.
