Dismantling of foundations

Dismantling of foundations is a complex engineering process that involves the demolition of structures that form the basis of a building. This procedure may be required both during reconstruction and during the complete demolition of an emergency building. You can order the dismantling of foundations at a favorable price in our company “Forest-Ukraine”.

Preparing for dismantling the foundation

Before starting the demolition of foundations, it is necessary to conduct thorough preparation. This stage is important for the successful and safe execution of the work. The preparatory process includes a detailed analysis of the object, planning and organization of safety measures, which allows you to avoid unexpected problems during dismantling.

Foundation condition assessment

Before the start of dismantling work, a detailed assessment of the condition of the foundation is carried out. The process includes the following:

1. Determining the type of foundation (strip, slab, pile, columnar).
2. Analysis of the materials from which the foundation is made.
3. Assessment of the general condition and degree of wear.
4. Measurement of size and depth of occurrence.
5. Determining the presence of reinforcement and its location.

An important aspect during the demolition and dismantling of foundations is the identification of potential risks. The main ones include proximity to other buildings and structures, the presence of underground utilities (water, sewage, gas pipelines), soil condition and type, the possibility of equipment access to the object, etc.

Work planning

Careful planning is the key to a successful demolition project. This process involves the following steps:

• Development of a detailed action plan.
• Determining the sequence of work.
• Calculation of necessary resources (human, technical, material).
• Drawing up a calendar schedule for the execution of work.
• Preparation of cost estimates.
• Determining waste disposal methods.

A particularly important element of planning is obtaining all necessary permits and approvals from the relevant authorities regulating construction activities.

Security at the facility

Ensuring safety is one of the most important aspects when dismantling foundations. Key measures include:

• Conducting detailed safety briefings for all participants in the work.
• Providing workers with the necessary personal protective equipment (helmets, safety glasses, gloves, respirators).
• Installation of warning signs and fences around the work area.
• Organizing regular inspections of the technical condition of equipment.
• Development of an evacuation plan in case of emergencies.
• Monitoring the structural integrity of neighboring buildings during work.

Regular inspections of equipment and tools, monitoring the condition of structures, and knowledge of safety rules by workers during dismantling allow for timely identification and elimination of potential risks.

Methods of dismantling foundations

The price of foundation demolition depends on the complexity of the task and the chosen dismantling method. Many factors influence its choice:

1. Type of foundation construction (strip, slab, pile, columnar).
2. Dimensions and weight of the structure.
3. The materials from which the foundation is made.
4. Availability of the territory for machinery and equipment.
5. Proximity to other facilities and buildings.
6. Project budget.
7. Work completion dates.
8. Environmental requirements and restrictions.
9. Possibility of reusing materials.

Modern technologies offer a variety of ways to demolish foundations, each with its own advantages and limitations.

Dismantling of strip foundations

Strip foundations are one of the most common types of foundations for buildings of various purposes. They are a continuous strip of concrete or reinforced concrete that runs under all the load-bearing walls of the building. Dismantling such foundations requires a special approach due to their considerable length and structural strength.

Manual dismantling

The manual method involves the use of jackhammers, perforators, crowbars and other hand tools. This method is laborious, but has a number of advantages, especially when working on small objects or in conditions of limited access. Manual dismantling allows for high accuracy of work, minimizing vibrations and noise.

Mechanized dismantling

Mechanized dismantling of strip foundations involves the use of special equipment (excavators with hydraulic hammers, bulldozers and cranes). This method is much more effective than manual, especially for large objects, where the volume of work is significant. The use of powerful equipment allows you to significantly reduce the time of work and reduce the cost of demolishing the foundation.

Dismantling of slab foundations

Slab foundations are a monolithic reinforced concrete slab that distributes the load from the building to the soil. Such foundations are characterized by a large area and thickness, which makes their dismantling quite difficult. For the effective demolition of slab foundations, special methods are used that allow the destruction of strong reinforced concrete with minimal time and resource consumption.

Diamond cutting

Diamond cutting is one of the most effective methods of dismantling slab foundations. This method involves the use of special diamond discs that are able to precisely cut concrete and reinforcement. Diamond cutting allows you to divide the slab into smaller fragments that are easier to remove from the area. The main advantage of this method is the minimization of vibrations, which is especially important when working near existing buildings.

Hydrocline

The hydrowedge method is based on the use of hydraulic wedges that create high pressure inside pre-drilled holes in the concrete. Under the influence of pressure, the concrete is split into pieces, which are then removed from the area. This method is particularly effective for thick slabs, where the use of traditional dismantling methods can be difficult.

Dismantling of pile foundations

Pile foundations are used in weak soil conditions or when it is necessary to transfer the load to deeper, more stable soil layers. They consist of vertical elements (piles) that are driven into the soil, and a grillage – a horizontal structure that connects the upper parts of the piles.

Pulling piles

Pile pulling is a method that involves completely removing the pile from the ground. This involves the use of specialized cranes with high lifting capacity and special equipment to grip the top of the pile. This method is used for piles made of metal, wood or reinforced concrete, if their design allows them to withstand the forces during pulling.

Pile cutting

The pile cutting method involves removing only the top of the pile, usually to a level that will not interfere with the future use of the area. The cutting process uses diamond cutting, which allows for precise and rapid separation of the top of the pile from its main body.

Choosing a method depending on the conditions

The choice of the optimal method of dismantling the foundation depends on many factors that must be taken into account to ensure the efficiency and safety of the work. To understand the specifics of choosing an approach, let’s consider them in the form of a table:
