Project description

Removing concrete foundations is a challenging task that is required in many construction projects. Whether demolishing old buildings, remodeling or redeveloping properties, an effective method of removing concrete foundations is crucial. Swelling explosives, also known as blasting concrete or swelling pressure agents, offer an innovative solution to safely and efficiently remove these heavy structures. The use of swelling explosives allows for explosion-free and precise crushing of concrete foundations, minimizing the risk of damage to surrounding structures. This method is not only environmentally friendly but also saves time, making it the preferred choice for contractors and remediation companies. Through the targeted use of swelling explosives, concrete foundations can be removed quickly and effectively, allowing construction work to continue swiftly.

Project schedule

The process of removing concrete foundations with swelling explosives requires careful planning and execution. First, a precise analysis of the concrete foundation is carried out to determine its size, depth and structure. This information is crucial for planning the boreholes and calculating the required amount of swelling explosive. After the analysis, a detailed drilling plan is drawn up. The borehole diameter must be between 25 mm and 45 mm to ensure the required expansion force. The distances between the boreholes should generally be ten times the diameter in order to ensure even pressure distribution. Closer spacing can be expected to result in faster cracking, which increases crushing efficiency. Once the drilling plan is approved, drilling of the holes begins. Each hole should be at least five times as deep as the diameter to ensure effective expansion of the swelling explosive. Once the drilling work has been completed, the swelling explosive is prepared and filled into the holes. The mixing ratio of 1.2 liters of water per 5 kg of swelling explosive is very important here. After the holes have been filled, there is a waiting period during which the swelling explosive can develop its effect. This process usually takes a few hours, after which the concrete foundations are broken into smaller pieces. The fragments can then be easily removed.

Drilling information

Drilling information is an essential part of the process when removing concrete foundations with swelling explosives. The borehole diameter, which should be between 25 mm and 45 mm, plays a decisive role in the effectiveness of the method. The material consumption per meter of borehole depends on the diameter and is as follows: 25 mm: 0.9 kg swelling explosive per meter 30 mm: 1.24 kg swelling explosive per meter 35 mm: 1.68 kg swelling explosive per meter 40 mm: 2.2 kg swelling explosive per meter 45 mm: 2.78 kg swelling explosive per meter The distances between the boreholes should also be well planned. The spacing is usually ten times the diameter. This ensures that the pressure is evenly distributed and that the fragments are the desired size. For thinner surfaces or special requirements, a smaller diameter with closer spacing can be selected to maximize crushing efficiency.

Consumption

The consumption of swelling explosives when removing concrete foundations depends on several factors, including the size and depth of the foundation and the size of the drill hole selected. On average, the consumption is around 10 kg of swelling explosive per cubic meter of concrete removed. An accurate consumption calculation is essential to ensure that sufficient material is available for the project. The material costs should be calculated in advance in order to plan the budget realistically. When calculating consumption, it is important to take into account the borehole diameter and the amount of swelling explosive required per meter of borehole. In this way, unexpected costs and delays can be avoided.

Time / Costs

Removing concrete foundations with swelling explosives offers significant advantages in terms of time and cost. Compared to traditional methods, which are often lengthy and expensive, the use of swelling explosives allows the work to be carried out more quickly. This explosion-free method not only minimizes the risk of damage to adjacent structures, but also reduces the need for additional safety precautions. The total duration of a project depends on the size of the foundation, the geological conditions and the amount of material required. Early planning and precise calculations help to optimize time and keep costs in check. The end result is an efficient and cost-effective project that meets the requirements of the construction industry.

Expert opinion

In summary, the removal of concrete foundations with explosives is a modern, effective and environmentally friendly solution. Through the precise application of this non-explosive method, concrete foundations can be removed quickly and in a controlled manner, allowing construction projects to continue quickly. The structured approach, from careful planning to precise drilling and effective application of the swelling explosive, ensures that the results meet expectations and protect the environment. The combination of efficiency, cost savings and safety makes the removal of concrete foundations with swelling explosives the preferred choice for many construction and demolition projects.
