Features of strengthening the foundation with drilled injection piles, turnkey price

For a building to last a long time and be safe, its foundation must be strengthened. Drilled injection piles are one efficient way to reinforce foundations. In order to create strong support structures, this technique entails drilling deep into the ground and injecting materials.

Drilled injection piles have a number of advantages, including improved load-bearing capacity and stability. They are especially helpful for structures that are having problems settling or that were constructed on shaky ground. Your building’s lifespan can be increased and additional damage can be avoided by strengthening the foundation.

The costs associated with this approach must be understood before proceeding. The cost of installing drilled injection piles, when paid turnkey, comprises all materials, labor, and any other work needed to finish the project. Being aware of these expenses up front facilitates efficient planning and budgeting.

The characteristics and advantages of drilled injection piles will be discussed in this article, along with a thorough analysis of the turnkey cost of this technique for strengthening foundations. This information will help you make an informed decision whether you’re planning a new construction or dealing with an old building.

Advantages of the method

The following benefits account for the technique’s widespread use:

1. Possibility of installation in places difficult to reach for construction equipment, as well as in areas with strong industrial vibrations.
2. Efficiency in restoring foundations with significant deformations, including load-bearing structures built from “wild” stone.
3. Applicability to the methodology of classical principles and formulas for calculating the number of supports.
4. High load-bearing capacity of the restored load-bearing structure, which is especially important for areas with loose, sandy and weak soil.
5. Bored injection piles serve as protection against landslides and also prevent the penetration of groundwater.
6. The presented type of load-bearing elements has smaller dimensions compared to bored piles, but is not inferior to them in terms of load-bearing capacity and service life.
7. The installation of drilling injection supports can be carried out under any geological conditions on the site.

Turnkey prices

Depending on the pile diameter, the majority of domestic manufacturing companies charge between 1800 and 4600 rubles per meter on average for their foundation strengthening services.

The costs listed in the table are only estimates because the total cost of the turnkey service varies depending on the job’s complexity and initial conditions.

What is included in the cost of work?

The developer will provide the client with an estimate that includes a thorough breakdown of the procedures and cost items prior to beginning any work. Generally speaking, the technical specs include the following information:

Creating a work schedule;

Computation of allowable loads;

Delivery of equipment and building supplies;

Setting up the casing pipes;

What is the technique??

Labor-intensive preparatory work is required in order to use drilled injection piles technology for rebuilding the foundation. This work includes:

• excavation of soil from the outside and inside of the existing foundation;
• drilling wells using a hammer drill or auger drilling installation.

Technology states that holes are punched in increments of 80 to 120 cm in a checkerboard pattern.

Reinforcement of supports is used for the foundations of multistory buildings and other heavy structures. Steel pipes, welded frames, rolled ferrous metals, or a single reinforcement are used in the technological process.

Casing pipes are used to reinforce wells in weak and floating soils; these pipes can be removed once the well has been filled with solution.

The next step is to use cement-sand mortar to fix injection hoses or tubes with a 50 mm diameter in the pits. The solution can be poured straight into the casing pipes once the well’s bottom has dried.

Then, using a turbulent pumping station, a solution is pumped into the well at a pressure of 0.2 to 0.3 MPa. In this instance, concrete can spread within a radius of 0.5 to 1 m in both the base’s body and the soil that comes into contact with it.

The amount of base damage and the characteristics of the soil determine how much concrete solution is used. In actuality, 20–40% of the volume of the repaired load-bearing portion of the structure is consumed by concrete. The final step involves applying excessive pressure to the concrete, which causes the solution to seep even further into the foundation’s pores and the surrounding soil.

Distinctive features of strengthening foundations with this type of support

Drilled injection piles represent a category of cast-in-place structural elements. Their small diameter (d=150-450mm), relative flexibility, and manufacturing process (injection of solution into the well) set them apart.

The following variables affect how often holes are drilled, how deep they are, and what kind of cement mortar is used:

• the type of old foundation and the degree of its damage;
• engineering and geological features of the site;
• level of underground sources.

Significant shock and vibration loads are not applied to the existing foundation while the supports are being installed. This eliminates the risk of damage during the reconstruction of historic buildings and allows work to be done in landslide-prone areas.

Drilled injection pile foundation strengthening is a dependable and effective way to stabilize and reinforce current structures and guarantee their long-term durability. This technique entails drilling holes all the way around the foundation, injecting a mixture to form piles, and providing a full turnkey service that covers everything from the preliminary inspection to the last installation. Homeowners and builders can increase the stability and value of their properties by making educated decisions if they are aware of the procedures and associated costs.

For what reasons is this method suitable??

The following foundation types can benefit from the drill-injection support strengthening method:

1. Concrete, reinforced concrete and rubble strip bases. A distinctive feature of the technology is to drill wells in the shape of a cone, where casing pipes and reinforced frames are then placed and the entire structure is filled with mortar.
2. Columnar, pile and pile-grillage grounds. The technology allows you to install new load-bearing elements under the existing grillage or replace deformed supports with drilled injection piles.
3. Monolithic slab bases. To strengthen the foundation effectively, choose heavy-duty concrete.

Rebuilding any kind of foundation requires the use of universal load-bearing components, such as drilled injection supports.

The technique’s viability is restricted by the requirement to choose pricey concrete grades in certain instances and a high building material consumption. In turn, the level of subterranean sources, the kind of soil, its freezing point, and maximum loads all affect the composite composition of the solution.

Drilled injection piles are a useful tool for reinforcing the foundation and extending the life of buildings. Using this method, piles are created by drilling holes around the existing foundation and injecting a particular grout. These mounds aid in more even load distribution and offer extra support.

This technique is especially helpful for buildings whose foundation problems are brought on by shifting soil, water damage, or aging structures. Homeowners can solve these issues without having to disrupt the building or conduct extensive excavation by employing drilled injection piles.

The size of the project, the state of the current foundation, and local labor rates should all be taken into account when estimating the cost of this procedure. Even though a solid foundation may seem expensive initially, the advantages over time greatly exceed the expenses.

Choosing a turnkey solution guarantees that experts will manage every facet of the project, from planning to execution. This method ensures high-quality materials and workmanship while also saving time.

To sum up, drilled injection piles are a dependable way to reinforce your foundation, giving you peace of mind and prolonging the life of your structure. Given its efficacy and efficiency, this approach is worthwhile for individuals dealing with foundation problems.
