Foundation Underpinning 101

Foundation underpinning enhances the strength of an existing foundation by extending it to more supportive soil layers, ensuring your property’s stability.

The Underpinning Procedure

This process involves carefully excavating soil beneath the existing foundation in stages. A geotechnical engineer assesses the soil to locate suitable strata capable of supporting your building’s weight.

Replacing Soil with Concrete

After excavation, the removed soil is replaced with new material, often concrete, forming a new foundation beneath the original one and reinforcing your property’s structure.

Diverse Underpinning Methods

Several underpinning methods exist, including the mass pour method for heavy loads, the beam and base method for entire foundations, and the mini-piled method for variable ground conditions.

When to Consider Underpinning

Underpinning is crucial when original foundations cannot support the structure or when soil conditions change. It’s necessary if building usage changes, additional floors are added, or you desire extra depth in subsurface spaces.

A Solution to Numerous Issues

Whether dealing with settling propertys, poor construction workmanship, changes in property usage, or adjacent building construction, underpinning offers a reliable solution to enhance structural integrity.

Types of Underpinning Methods

The strength and durability of your property depend significantly on the underpinning method used. Here’s an overview of various techniques and their unique advantages.

• Mass Concrete Underpinning (Pit Method): A traditional method that extends the old foundation to a stable stratum, increasing depth and load-bearing capacity.
• Beam and Base Underpinning: Involves placing a reinforced concrete beam on mass concrete bases below the existing foundation to redistribute the load.
• Mini-Piled Underpinning: Uses slender piles drilled into stable soil layers, filled with concrete to provide reinforced support.
• Piled Raft Underpinning: Employed when an entire building needs underpinning; piles are driven in a grid pattern before placing a supporting raft.
• Expanding Resin Injection: Focuses on soil stabilization by injecting a mixture of resin and hardener into the ground to increase solidity.

Selecting the right underpinning method significantly increases your property’s strength and longevity. 

Moreover, these methods also improve resistance to external pressures. Careful consideration is essential before choosing an underpinning method to benefit your property’s structural integrity.

Benefits of Steel Push Piers

Steel push piers enhance your property’s structural integrity with their remarkable load-bearing capacity and sturdy steel construction. Unlike concrete alternatives, these piers adapt to shifting soil conditions, ensuring longevity and reliable underpinning support.

• Scientifically Validated: Audited by the International Code Council and recognized as an effective foundation repair method.
• Safety and Stability: Provide security using high-strength, round steel tube sections.
• Corrosion Resistance: A triple-layer galvanized coating prevents corrosion, ensuring durability.
• Limited Access Installation: Portable devices allow installation in zones with restricted access.

Load testing during installation ensures each pier’s security and stability. With a quick installation process and minimal disturbance to your property, steel push piers are a reliable choice.

Exploring Helical Piers

Helical piers, also known as screw piles, are adaptable solutions for various foundation issues. Their versatile design allows penetration through diverse soil conditions to stable layers.

Helical piers offer minimal excavation, reducing costs and installation time compared to other deep foundation techniques. 

They provide lateral support, mitigating the effects of shifting ground, with strengths ranging from 60,000 to 120,000 pounds. Installation causes negligible vibration and can be done in any season, offering flexibility and reliability.

The Underpinning Process Explained

Underpinning reinforces an existing foundation by enhancing its depth or width, providing stability and preventing structural issues.

Initial Excavation

Systematic excavation of soil surrounding your foundation creates space to pour concrete beneath your property, offering additional support.

Preparation Phase

Formwork and steel reinforcements are installed to ensure the new concrete fits perfectly below the existing foundation.

Reinforcement and Infilling

Concrete is poured into the formwork and allowed to set. Excavated soil is then replaced and compacted for reinforcement.

Post-Process Repairs

With the foundation secured, necessary repairs to your property’s exterior and interior can begin.

Underpinning requires professional expertise due to its complexity. Signs such as wall cracks or uneven floors may indicate the need for underpinning.

How Underpinning Prevents Water Damage

Underpinning strengthens your property’s foundation and helps prevent water damage by enhancing structural integrity.

• Foundation Reinforcement: Mitigates risk of shift and settlement, reducing cracks that cause water infiltration.
• Sealing Foundation Cracks: Ensures cracks are sealed, preventing groundwater seepage.
• Improving Drainage: Adjusts groundwater flow away from the foundation, alleviating water pressure against walls.
• Sump Pump Installation: Aids in handling accumulated water, averting flooding risks.
• Foundation Waterproofing: Applies watertight materials to prevent water intrusion, maintaining a dry environment.

Underpinning not only reinforces your foundation but also provides opportunities to implement effective waterproofing measures, resulting in a resilient structure.

Insights from Foundation Repair Experts

Underpinning significantly influences your building’s stability. Costs can range from $2,000 to $30,000, depending on various factors:

1. Severity of Damage: Greater damage requires comprehensive solutions.
2. Underpinning Method: Different methods have varying costs.
3. Number of Piers Required: More piers increase expenses.
4. Soil Condition: Complex conditions increase excavation difficulty.
5. Access to Foundation: Difficult access raises labor costs.
6. Your Location: Urban areas may have higher costs.
7. Size of Your House: Larger propertys require more resources.

Obtain estimates from multiple contractors to compare costs and understand the scope of work. Research companies with strong reviews. For detailed cost information, refer to this source. Well-managed underpinning contributes to a longer lifespan for your property.

Reviewing Recent Underpinning Projects

Underpinning can enhance your property’s strength and safety. Notable projects illustrate its effectiveness.

Hillside property Stabilization

A San Clemente property had sunk 16 inches, tilting towards a hillside. Using 27 vertical helical piles and five helical tiebacks successfully lifted and stabilized the structure.

Backyard and Pool Security

A Murrieta property’s backyard and pool were settling. Underpinning with 87 vertical helical piers and 27 helical tiebacks stabilized the outdoor area.

Foundation Preservation

A Brea property’s foundation was compromised after a remodel. Preventative underpinning using push piers and polyurethane injections protected the property from future settlement.

Choosing the Right Underpinning Solution

Underpinning services are crucial when the existing foundation lacks strength or soil supporting its changes. Recognize foundation troubles through signs like shifting buildings or weakening foundations.

Recognizing Foundation Troubles

Serious damage due to unsuitable soil or differential settlement necessitates underpinning. Soil investigation before construction can reveal stability issues.

Addressing Structural Conditions

If your property is built on insufficient soil or uses settling wood piles, underpinning is necessary. Changes in the water table can further compromise stability.

Applying Underpinning Methods

Various approaches like Mass Concrete, Beam and Base, Grouting, Micro-piling, and Jet Grouting are available. Choosing wisely ensures enduring stability and safety for your property.
