How to select Foundation repair method

Major consideration - Engineering Design:

Soil Profile - Assessing soil capacity, water levels, and soil type to determine suitability.
Foundation Design - Analyzing the existing foundation and identifying the causes of structural issues.

Minor Considerations - Construction method/Budget:

Equipment Accessibility - We assess whether machinery can easily access the site to determine the most suitable method, whether underpinning or injection.
Structural Impact - We evaluate potential risks of further damage to the existing structure, such as impacts from temporary construction activities like floor openings or slab coring.
Resident Impact - Our goal is to minimize disruptions and inconveniences to residents, ensuring a smooth experience during the construction process.
Environmental Considerations - We adhere to client specifications regarding allowable noise and dust levels to ensure compliance with environmental standards.
Project Timing and Budget - We strategically plan to meet project deadlines while adhering to financial constraints, balancing efficiency with cost-effectiveness.

Ground Injection Technique

Underpinning

Underpinning is a solution that meets Eurocode or British Standards requirements, ensuring compliance with safety factors.
Underpinning methods are designed with a built-in safety factor, ensuring structural stability and compliance with engineering standards.
The process allows for detailed quality control, ensuring that the materials and methods used meet the required standards.
Underpinning methods allow for real-time inspections, ensuring that any issues can be addressed immediately during the construction process.
MLT and PDA testing can be performed to ensure precise assessment of pile strength and load-bearing capacity.
Underpinning offers a fixed cost structure, providing a clear budget from the start.

Solutions by

Ground injection solutions, using either polyurethane (PU) or cement grout, are designed to fill voids and enhance the soil's compressive capacity, thereby strengthening the surrounding ground.
PU injection is a modern, quicker solution for soil stabilization that doesn’t typically require extensive excavation.
Compared to traditional underpinning, PU injection causes minimal disruption to the existing structure and surroundings.
While effective, PU injection doesn’t allow for as much hands-on inspection during the installation, as the material is injected below ground, making it harder to visually assess progress in real time.
Seismograph wave testing is conducted to assess subsurface conditions and soil properties by measuring the propagation of seismic waves through the ground.
PU injection is priced per kilogram, leading to potential cost variations based on the amount of material used.
