What Is an FBS Foundation and Why It Needs to Be Dismantled

An FBS foundation (solid concrete block foundation) is one of the most common base types used in residential, industrial, and warehouse construction. These blocks are known for their strength, durability, and stability.
However, over time, situations may arise that require FBS foundation dismantling.

Reasons include: building reconstruction, design errors, structural damage, or the need to relocate a structure. Dismantling may also be necessary during major renovations or when redesigning a land plot.

Key Features of FBS Blocks

FBS blocks are made of heavy concrete and come in standard sizes — lengths of 880, 1180, or 2380 mm and widths between 300–600 mm.
Due to their high density (up to 2500 kg/m³), dismantling requires the use of specialized equipment.
The blocks are joined with cement mortar, which makes disassembly more challenging and requires precision.

Preparation Stage for FBS Foundation Dismantling

Before any dismantling begins, it’s essential to conduct a detailed inspection of the structure, assess the block condition, foundation depth, and groundwater level.
Based on these factors, a technical plan and cost estimate are created.

Important aspects to consider:

  • proximity of underground utilities;

  • soil stability;

  • overall work volume;

  • need for temporary reinforcement of nearby structures.

Once preparations are complete, the necessary permits are obtained and the site is secured for safe operations.

Methods of FBS Foundation Dismantling

Several dismantling methods are used depending on block condition, accessibility, and available equipment.

Mechanical Dismantling

This is the most common method, involving excavators, hydraulic hammers, and cranes. Cranes lift and remove the blocks, while excavators assist in loosening them from the base.
It ensures speed and efficiency but requires professional experience to avoid damage.

Manual Dismantling

Used for small-scale projects or locations where heavy machinery cannot access. Workers use crowbars, jackhammers, and demolition hammers.
Although slower, it allows precise control and reduces vibration risks.

Hydraulic and Vibrational Dismantling

A modern technique employing hydraulic shears and vibratory tools that break concrete without excessive impact.
This minimizes damage to nearby structures and significantly reduces noise levels.

Equipment and Tools Used for FBS Dismantling

Common tools and machinery include:

  • excavators and cranes for lifting and removal;

  • jackhammers and hydraulic hammers;

  • diamond saws and wire cutters for smooth, precise concrete cutting without cracks.

Diamond tools are especially effective in confined spaces or indoor areas where vibration must be minimized.

Safety During Concrete Block Dismantling

Concrete dismantling is classified as high-risk construction work.
Workers must wear helmets, gloves, goggles, hearing protection, and respirators.

Typical safety mistakes:

  • underestimating block weight;

  • failing to assess soil stability;

  • improper load securing when lifting.

A qualified supervisor should oversee operations to ensure compliance with safety standards.

Disposal and Removal of FBS Concrete Blocks

Once dismantling is complete, debris removal and disposal must be organized.
Concrete can be recycled and reused as crushed stone or road base material.
This reduces costs and environmental impact. Many recycling centers accept FBS blocks for secondary processing.

How Much Does FBS Foundation Dismantling Cost

The cost depends on several factors:

  • total work volume;

  • block condition;

  • accessibility for equipment;

  • region or city.

How to Choose a Contractor for FBS Dismantling

When selecting a contractor, pay attention to:

  • availability of proper machinery and permits;

  • documented experience in similar projects;

  • customer reviews and references;

  • official contract and warranty.

Avoid hiring unlicensed or unregistered crews — they often ignore safety rules and may cause structural damage.

Benefits of Professional FBS Dismantling

Professional dismantling offers clear advantages:

  • time and cost savings;

  • safety assurance;

  • compliance with construction standards;

  • guaranteed quality results.

Licensed contractors are responsible for outcomes and provide official documentation of completed work.

Frequently Asked Questions (FAQ)

1. Can I dismantle an FBS foundation by myself?
Yes, but only if you have proper experience and equipment. For large foundations, professional services are strongly recommended.

2. How long does dismantling take?
Typically from 1 to 5 days, depending on the foundation size and complexity.

3. Can dismantled FBS blocks be reused?
Yes, if they remain undamaged after removal.

4. Are permits required for dismantling?
Yes, especially in urban or regulated construction zones.

5. How should concrete waste be disposed of?
It can be taken to recycling facilities or reused as filler material in construction.

6. How can I reduce the cost of dismantling?
Compare quotes from multiple companies and consider handling waste disposal independently.

Conclusion

FBS foundation dismantling is a complex yet manageable process when properly planned.
With careful preparation, suitable equipment, and a professional approach, the work can be completed safely, efficiently, and cost-effectively.

Hiring experts ensures compliance with safety regulations, preserves surrounding structures, and guarantees high-quality results.
