Piling & Underpinning services we offer in Kwazulu Natal

We offer the following foundation and structural repair services in and around KwaZulu Natal:


We inspect the site in order to establish the cause of the cracking.  There may be causes such as leaking pipes, storm water drains, soil type (clay, shale), land slide, land slip, etc, that may cause foundations to subside or move, resulting in the cracking of the building.  We work closely with a Geo Tech’s/Structural Engineers whose services may be utilized in certain circumstances. 

Based upon our findings, we will give recommendations for the underpinning ie. number and location of pins.  In some cases sub-soil drainage may need to be installed and/or storm water may need to be properly managed in addition to the underpinning.  Stitching may also be recommended. We offer a turnkey solution for any project, including the design and installation of all types of storm water problem solutions and the the installation of continuation tanks and soak aways.


When underpinning, we dig and expose the foundations at the location that the pins are to be installed. We then dig approximately 1.5m below the foundation in order to install precast jack piles with steel and anchor crete. Using a specialised hydraulic jack, we jack precast jack piles down until they come to hard resistance or solid rock, welding them together along the way.

Finally, a concrete plinth is installed between the top of the precast jack piles, steel, and anchor crete and the existing foundation. The surrounding soil is then replaced and compacted.

Based upon our findings, we will give recommendations for the underpinning ie. number and location of pins.   In some cases sub-soil drainage may need to be installed and/or storm water may need to be properly managed in addition to the underpinning.  Stitching may also be recommended.

Where sub-soil drainage is required, trenches need to be dug below the foundations. Bidem cloth is installed into the trenches with agricultural pipe and 19mm blue stone around the pipe.


Piling is the process of adding support or strength to a building. From a more technical perspective, piling is commonly understood as a method of transferring weights within soil by driving or boring into the ground at particular spots.

Uneven structures or weak foundations are common causes of piling. The intended building and its immediate surroundings are stabilised and supported reliably by the process of driving piles into the earth.

The piles continue through several levels of soil until they hit a solid rock or soil layer. The next step is to attach the supports, which will act as a base for the building and disperse its weight equally across the ground.

As a general rule, piling is employed whenever multiple elements are present. Preexisting foundations or trenches might be too expensive or unstable to remove, there could be a high water table that affects soil stability, and the selected site could have inappropriate ground that can’t hold the weight of the building without reinforcement. Piling has many potential applications, from sustaining massive constructions like bridges and skyscrapers to more modest ones like home additions and detached garages.

When it comes to foundation solutions, Pinnacle Structure Repairs is at the forefront of innovation. The importance of piling to a building’s durability and stability is something we, as a prominent industry leader, are well-aware of.

Our engineering crew does a thorough site evaluation before getting into the nitty-gritty of applicable piling types. To guarantee the best possible foundation performance, many environmental factors are carefully considered, including soil conditions, weather, and others. By working with architects, we gain a deeper appreciation for the scope and complexity of the project.

Our engineers carefully choose the best piling type after thoroughly analysing the site characteristics and project requirements. Selecting the right sort of pile—driven, bored, or screw—is essential for overcoming obstacles and ensuring a structure lasts as long as possible.

Sites with thick soil or rugged terrain, for example, are perfect for driven piles since they make traditional excavation procedures more easier. In contrast, bored piles work great in places with softer soil or for projects that need deeper foundations. For regions that are delicate to the environment or where minimal disruption is preferred, screw piles provide a flexible solution.

Our objective is straightforward: to optimise the building process while simultaneously increasing the foundation’s stability and durability by doing the best and appropriate piling for the project. Using the correct piling solution from the start guarantees that your project will endure the elements and provide a strong base for decades to come.


Planning Essentials

The lifetime and durability of buildings are greatly affected by the piling material that is chosen during construction. Timber, with its combination of low weight and longevity, has long been considered the material of choice. For many years, piling was all about timber, thanks to its renown for being easy to work with and prepare.

But as time went on and technology improved, new materials like steel and concrete changed the face of the construction sector. Modern manufacturing techniques and more contemporary building procedures ushered in the era of steel and concrete piles.

Because of their malleability, steel and concrete are incredibly versatile building materials. They are more resistant to compressive bending and tensile stresses than timber because of their

resilience. The versatility, longevity, and multipurpose nature of steel and concrete have made them the materials of choice for many modern construction projects.

Steel, in particular, is well regarded for its remarkable durability, which allows it to endure even the most demanding drilling procedures. One reason why it’s so popular among experts in the field is how simple it is to make.

Careful consideration of the pile’s design is as important as material selection. Careful consideration of soil conditions and expected load-bearing forces is essential when designing piling foundations. Particularly in settings where piles and soil layers are subject to horizontal movement, designs should take axial, shear, and bending forces into consideration.

Environmental variables are also taken into account, such as the requirement for piles to resist uplift loads in tall structures or those that are exposed to strong wind or wave forces. Piles used at sea must be able to resist the sideways forces exerted by ships as they dock. In a similar vein, retaining walls, bridges, and piers must take horizontal and vertical loads into serious consideration.

We at Pinnacle Structure Repairs know how the material of the pile, the technique of installation, the ground conditions, and the loading forces all interact with one another. Every project is carefully planned and performed to endure the test of time because we take a holistic approach. You can trust that your constructions will be built to last with our experience, and we will ensure that they perform to the highest standards in the construction industry.

Sub-Soil Drainage

Where sub-soil drainage is required, trenches need to be dug below the foundations. Bidem cloth is installed into the trenches with agricultural pipe and 19mm blue stone around the pipe.


Where stitching is required, a horizontal cut is made into the brick and mortar. We install a 6mm steel bar with concrete epoxy. The wall is then patched.
