In this article we will discuss the micropile definition, installation process and its benefits.

If you are a civil engineer, surely you should know how important the foundation of a building or construction is, but when it comes to all its essential parts, there are situations in which you do not know what are the best and most appropriate options for piles that you are going to use in your project.

On many occasions, there are people in construction who have never heard of micropiles. These are one of the best options used when installing deep foundations that can also include drilling the rocks that the terrain of your project has.

If you know little or maybe nothing about micropiles and you are curious about why they are so important for the foundations of your projects, in this article we will explain everything you need to know about micropiles: both their benefits and their importance.

Micropiles definition

Micropiles are generally known as mini-piles . They are elements that are built with high quality steel covers and are characterized by being very durable. They have a small diameter or threaded bar; In addition, micropiles are generally used in the installation of deep foundations.

Reasons to use micropiles

There are many reasons to use micropiles in your projects. Next, we are going to tell you which are the most common so that you take them into account when necessary.

  • micropiles provide structural support;
  • they serve when supporting your foundation;
  • are very good at transferring large loads, and
  • are responsible for improving stability.

This means that micropiles are one of the best alternatives that you can use when you need help to prop up your base, since they minimize the settlements of the bases and are ideal when working on soils with low bearing capacity, in difficult areas. or with little access.

Micropiles installation process

  1. The micropile installation process begins with the excavation of a hole with a great depth and a small diameter.
  2. After you have cleared the place for the micropile, the pile basket is inserted, which must meet the proper specifications.
  3. Next you need to fill the hole with the concrete grout mixture in order to hold everything in place.
  4. Once you let the structure settle, you can install the support system that is located on top of the micropile. This system is responsible for distributing the weight of the structure evenly and guarantees adequate contact with the supported base.

Micropiles main benefits

The micropile option is one of the most profitable and practical foundation construction solutions. Micropiles are characterized by having an easy installation method thanks to their light and compact nature. They are widely used in projects that have confined or very remote areas, such as steep slopes, basements, overpasses and even the foundations of swamps and wetlands.

You can also install them at different angles and they are capable of supporting lateral and axial loads.

It is an ideal option for building in rocky areas, this is because they are capable of securing inside the rock and actually extract load capacities from it.

Micropiles ideal for structural reinforcement

Currently they are widely used in structures that need repair or reinforcement of their base, but the main benefit they offer is their profitability and durability, since their installation takes less time than other types of piles, in addition to the environmental impact is more positive.

Final aspects that you should take into account about micropiles

If you find yourself installing a deep foundation or repairing an existing one, micropiles are elements that can certainly make your job easier.  They will surely reduce the costs of your project, shorten execution schedules and have a much easier way of installation, compared to other types of piles.
