Why Basement Underpinning Is Worth It

1
Site Inspection & Engineering
We start with an on-site inspection of your basement and foundation.
Our team evaluates soil conditions, existing footing depth, structural loads, and ceiling height goals.
If required, we work with licensed structural engineers to prepare drawings and obtain permits.
2
Permits & Preparation
Before any excavation begins, all necessary permits are secured.
We protect your home, set up temporary supports, and plan the work in safe sections to maintain structural integrity at all times.
3
Section-by-Section Excavation
Underpinning is performed in small, controlled sections (pins).
Each section is carefully excavated below the existing footing to the required depth, ensuring the foundation remains fully supported throughout the process.
4
Forming & Concrete Pour
Once the section is excavated, formwork is installed and high-strength concrete is poured to create a new, deeper footing.
After curing, the load is safely transferred to the new foundation level.
5
Repeat & Structural Completion
The process is repeated section by section along the entire foundation until the desired basement depth and ceiling height are achieved.
6
Waterproofing & Drainage (Optional but Recommended)
After underpinning, we strongly recommend basement waterproofing and drainage upgrades.
This includes:
Weeping tile installation
Sump pump systems
Foundation waterproof membranes
This protects your newly lowered basement from future water issues.
7
Final Inspection & Ready for Renovation
Once the work is complete, final inspections are arranged.
Your basement is now structurally reinforced, deeper, and ready for renovation, walkout conversion, or additional living space.
