Foundations can be categorised as shallow or deep foundations. Shallow foundations are used when the load imposed on the structure is relatively low to the bearing capacity of the surface soil. While deep foundations are necessary where the bearing capacity of the soil is enough to support loads. Traditionally, they have been used for large construction and engineering projects.
Different types of piling
Although many companies are offering piling services, what makes us best is that we are equipped with the latest tools and equipment for providing cost-efficient services. When determining the best piling type for a project/construction site, first, engineers examine a few factors, including:
- Depth of excavation
- The angle at which the pile needs to be installed
- The environmental issues that impact residents nearby
- End-bearing piles: engineers design this type of pile to transfer the heavy load of a building through a pile. It is a column that cuts through a weak layer of ground so that the structure remains straight with the support of the strongest layer underneath.
- Friction piles: these piles are cylindrical. Friction piles use their full height to transfer the force a building generates into the soil. The amount of load a pile can support is directly proportional to its length, meaning at greater depths, the pile can hold more weight.
- Bored piles: these piles need to be pressed into the ground to form a whole that workers fill in with poured concrete. The advantage of this pile is that it is cast into position, meaning these bored piles are extremely secure. Engineers use bored piles because the installation produces less vibration than other piles.
- Screwed piles: they look like large steel screws that need to be fastened into the ground/soil using a circular motion.
- Timber piling: this piling has been used for thousands of years in construction, installed with the driving method. These are highly efficient, safe and economical solutions for temporary and permanent structures.
- Concrete Piling: this type of piling is common in offshore construction projects, such as oil rigs, bridges and floating airports.
When is piling used?
- Piling belongs to the deep foundation category and is used where soil conditions do not allow shallow foundations.
- It is used for larger construction sites because it is considered suitable and much safer.
- When the soil at shallow depth is compressible
- Where there is the possibility of scouring due to its location near the river bed or a seashore
- When there is a drainage system or a canal near the construction site
- When soil excavation is impossible
- When it becomes impossible to keep the foundation trenches dry or for another reason such as heavy seepage inflow.

Our piling service process:
- Ground Analysis: our ground analysis or site analysis is the first step of our process in construction, regardless of the construction size and type. It is the same as a painter preparing his canvas before painting. If the canvas is not in shape, neither will the painting. Our engineers will analyse the soil quality and calculate its load-bearing. Furthermore, we will also check if the soil needs to be replaced or not. Vegetation can cause serious soil variation, resulting in shrinkage or expansion of the ground, which can harm the infrastructure. Nearby buildings will also be studied.
- Site clearance: the next step we will perform is site clearance. It is simply the site’s clearance, which includes removing all garbage, waste, natural and artificial structure, excavation, refilling and ground levelling.
- Piling: After identifying the type of piling based on the information mentioned above, we begin concrete piling work depending on the method.
Why choose us for your next construction project:
- Our highly skilled staff includes architects, civil engineers, geotechnical engineers, construction workers, etc. These professionals are licensed and fully aware of the building regulations and the industrial practices, providing you with hassle-free and legal services.
