Basement Underpinning Methods
When considering basement underpinning, it’s important to understand the different methods available. Each method has its own advantages and cost implications, which can influence the overall budget for your project.
Varieties of Underpinning
Underpinning is commonly used to strengthen and stabilize existing foundations. Here are the main varieties:
Mass Concrete Underpinning: This traditional method involves excavating sections of soil below the foundation and replacing them with concrete, increasing the depth and stability. It is suitable for houses with shallow foundations.
Beam and Base Underpinning: This method involves installing concrete beams below the existing foundation, which are then connected to mass concrete bases. This technique is ideal for properties with varying soil conditions.
Mini-Piled Underpinning: Used in scenarios where access is restricted or soil conditions are poor, mini-piles are drilled into the ground to support the foundation. This method is effective in challenging environments.
Screw Piles and Brackets: Screw piles are driven into the ground, and brackets are attached to the foundation. This method is quick and causes minimal disruption to the surrounding areas.
Underpinning Method | Cost Range | Suitability |
---|---|---|
Mass Concrete | $12,000 – $30,000 | Shallow foundations |
Beam and Base | $15,000 – $40,000 | Varying soil conditions |
Mini-Piled | $20,000 – $50,000 | Restricted access, poor soil |
Screw Piles & Brackets | $10,000 – $25,000 | Minimal disruption |
Alternative Methods: Bench Footing
Bench footing is an alternative to traditional underpinning that can be cost-effective. Bench footing involves creating a ledge or “bench” inside the foundation walls, allowing for additional space without needing to dig below the existing foundation. This is especially useful for transforming crawlspaces into usable areas.
Method | Description | Cost Range | Benefits |
---|---|---|---|
Bench Footing | Creating a ledge inside foundation walls | $10,000 – $20,000 | Cost-effective, increases usable space |
Crawlspace Transformation | Converting crawlspaces to basements | $5,000 – $15,000 | Adds functional space, less invasive |
These alternative methods offer options for homeowners looking to expand their living space without the higher costs of traditional underpinning techniques. By understanding these various methods and their costs, stay within your budget and meet your home improvement goals.
