Our References for Deep Foundations

As a homeowner, you should consider the soil conditions before construction begins.

Why should I, as a homeowner, think about the floor first?

As a builder, you have to juggle thousands of things at once.
No wonder so many project managers don’t think about soil conditions until just before construction begins.
But be careful! Because a lot can go wrong there …

If the ground is too soft, your structure will gradually sink and become increasingly crooked.

Cracks are forming in the building, causing windows and doors to no longer close properly.

And if gas lines end up at an angle, it can get really dangerous.

But it doesn’t have to come to that.

With the right service provider, you can easily avoid all of that.

3 Criteria for a Smooth Start to Construction

Before you begin working with your contractor, you should make sure that these three criteria for successful deep foundation work are met …

1. Site Investigation and Structural Analyses

Assess your building site and consult experts to perform structural calculations for the deep foundation. This will ensure that the deep foundation can be installed properly.

2. Permits

You must first obtain the necessary permits for your deep foundation work.

3. Coordination with Other Trades

To avoid delays, it is important to coordinate schedules with other trades before beginning the deep foundation work. This will ensure that your project can proceed without interruptions.

Here at THADE GERDES, we’ll take care of everything for you!

Stable Construction Projects -
with THADE GERDES

Before a construction project can and may begin, the soil must be tested. This ensures that it has sufficient bearing capacity and can support the load of the planned structure.

From displacement screw piles to concrete columns for residential buildings, at THADE GERDES we’ll find the right deep foundation method for you:

With deep foundation testing, your soil is examined even before your construction project begins.

Here’s how it works:

1. Comprehensive Site Investigation

After a comprehensive site investigation, we’ll determine whether bored piles are a good fit for you.
In consultation with your structural engineer and the specialist responsible for calculating the required pile system, we’ll find the right solution for your site and your construction project.
The bored piles function like stilts underground, supporting your house securely.

2. Rapid Implementation

In many cases, a partial building permit is sufficient to construct the foundation. We then drill the piles as quickly as possible. Simply put, a deep hole is drilled into the ground, into which a steel reinforcement cage is inserted. The length of the cage corresponds to the depth of the hole. The borehole is then filled with concrete, enclosing the reinforcing cage. Once the concrete has cured, the foundations of your structure can be built on this pile and other piles.
What’s more, we do this with almost no noise and without causing vibrations—so the neighborhood isn’t disturbed.

From the Initial Consultation to Deep Foundation Work

Initial Consultation (15 minutes)

During a no-obligation initial consultation, we’ll discuss the initial details of your project. What are your plans? By when does everything need to be completed? What documents do you already have on hand? Where is the construction site located? Once we’ve clarified everything, we’ll send you a quote.

2. Offer

Based on all the information you provide, we’ll prepare a quote for you promptly—and we’ll break down the costs so you have a clear overview of all expenses, with no hidden costs, of course!

3. Let's get started

Does this offer sound like a good fit for you? Then we can get started on your project right away. You’ll have a dedicated point of contact who will keep you updated at all times!

After the free initial consultation, we'll get started right away on planning your deep foundation.

Frequently Asked Questions

In northern Germany, the ground is often not stable enough for structures, primarily due to layers of peat and soft soil. These cause the ground to compress under the weight of a building, a phenomenon known as settlement. Depending on the soil type and weight, this settlement can amount to several decimeters and continue for years. This settlement can cause cracks in buildings and compromise their safety and functionality.

In these areas, deep foundations are essential to ensure the stability and safety of buildings.

A thorough site investigation is crucial for assessing the bearing capacity of your soil and thus identifying potential risks, such as settlement. This helps prevent problems during the construction process and ensures the stability of the structure.
The duration of the soil assessment depends on various factors, such as the size of the building lot and the potential complexity of the soil. However, our colleagues in the planning offices typically conduct a quick and efficient assessment.
Before deep foundation work can begin, several criteria must be met, including obtaining all necessary permits, performing structural calculations, and coordinating with other trades. THADE GERDES handles these preparatory tasks to ensure a smooth start to construction.

THADE GERDES has extensive experience with complex soil conditions.
We have developed specialized equipment and methods to work effectively even under difficult conditions.
