Redefining foundations for houses in 2024

House foundations are fundamental to all construction types, and RADIX’s cutting-edge technology enables us to cater to the diverse needs of our customers. Whether you’re looking for screw piles for houses, pondering over the varied types of house foundations, or seeking how to build house foundations, we are here to guide you.

We understand the importance of building foundations and footings that match the character of your project. It may be a wooden house, stone house, or modern house; we’ve got you covered. Our foundations also extend to structures like foundations SIP building, passive houses, granny annex, and eco houses.

Types of house foundations – It’s time to change and modernise

In the realm of house construction, foundation choices vary widely. Traditional foundations, like concrete slab foundations, basement foundations, pier and beam foundations, raft or mat foundations, or crawl space foundations, have been the norm for years. However, RADIX’s screws offer a compelling alternative, providing benefits such as reduced installation time and enhanced stability.

Sustainable construction in the house building sector with robust and sustainable foundations for houses

Our solutions encompass various kinds of construction, from a timber frame eco-house to modular building.

Even for those building passive house foundations or a SIP building with a specific interest in green building standards, we can support you. We cater to the requirements of modular house builders, eco house builders, and timber frame house builders alike, all the time focusing on reducing environmental impact.​

Taking into consideration factors like how deep are foundations for a house, how long do house foundations last, and the efficient foundation work itself, we ensure that every house foundation installed stands the test of time.

Why are screws better than concrete for your house foundations?

Screw piles, also known as helical piles, offer several advantages over traditional concrete foundations when it comes to building a house. While both have their place in construction, certain conditions and requirements may make our sustainable screws a more suitable choice.

It’s important to note that the choice between our screws and concrete foundations should be based on the specific requirements of the house-building project, including soil conditions, load requirements, environmental considerations, and budget.

Speed of installation

Screw piles are typically much faster to install than concrete foundations. Concrete requires time for pouring and curing, which can take several days or even weeks. In contrast, our screws can be installed in a day or less, depending on the project’s scale, allowing construction to proceed more quickly.

Minimal soil disturbance

The installation of screws causes minimal disturbance to the soil. Unlike concrete foundations, which often require extensive excavation, screws don’t, leaving surrounding areas largely undisturbed. This is particularly beneficial in sensitive ecological areas or where it’s important to maintain the integrity of the surrounding landscape.

Immediate load-bearing capacity

Screw piles can bear loads immediately after installation. Concrete, on the other hand, requires time to gain strength as it cures. This immediate load-bearing capacity of our screws can significantly expedite construction schedules.

Versatility in soil conditions

Screw piles are adaptable to a wider range of soil types compared to concrete foundations. They can be used effectively in areas with loose soil, high water tables, or even in places where traditional digging and excavation might be challenging.

Environmental impact

Screw foundations are considered more environmentally friendly. They require less concrete (a significant source of CO2 emissions during production) and less excavation, which means lower overall carbon footprint.

Challenging locations

Screw foundations are ideal for locations that are hard to access or where heavy construction equipment cannot be used. The installation equipment is typically smaller and more manoeuvrable.

Durability and resistance

Screws are highly resistant to ground movement, making them suitable for areas prone to earthquakes, flooding, or soil erosion. They can are galvanised to prevent corrosion, extending their lifespan.

Overall cost-effectiveness

While the initial cost of screw foundations can be higher than concrete in some cases, the overall cost benefits become apparent when considering the reduced labour costs, faster installation, and minimal site preparation required.

Less weather dependent

The installation of our screws is less affected by weather conditions compared to pouring concrete, which can be sensitive to extreme temperatures and moisture levels.

The installation process for a house using RADIX’s sustainable foundations

Site assessment and planning

Initial survey: Before installation begins, a thorough survey of the site is conducted. This includes assessing soil type, understanding the terrain, and identifying any potential obstacles or challenges. Load tests and calculations based on engineer reports will be done to select the best screws to use and at what depth optimisation occurs.

Design and planning: Based on the survey, a foundation plan is developed. This plan determines the number of screws needed, their placement, and the depth to which they must be installed.

Preparation of the site

Clearing and marking: The site is cleared of any debris or obstructions, and the locations for each screw are then marked according to the foundation plan.

Installation of screw foundations

Equipment setup: Specialised screw piling installation equipment, typically a hydraulic drive motor attached to a construction vehicle like an excavator, is set up on-site, or a smaller hydraulic installation machine on tracks can be used.​

Installing the screws: Each screw is positioned at its marked location. The hydraulic drive motor is used to rotate and screw the pile into the ground. The process is akin to screwing into wood but on a much larger scale.

Depth and torque monitoring: As the pile is driven into the ground, the depth and torque are closely monitored. This ensures that each pile reaches the necessary depth and is installed with the correct force, providing the required load-bearing capacity.

Levelling and adjustments

Ensuring level foundations: Once the screws are installed, they are checked for levelness. Adjustments are made as necessary to ensure that the tops of the piles are at the correct height and orientation for the building structure.

Attaching foundation brackets

Securing the structure: After the piles are in place and levelled, foundation brackets are attached to the tops of each screw. These brackets are what connect the screws to the structure of the house, ensuring a secure and stable foundation.

​Quality checks and final inspection

Inspection: A final inspection is conducted to ensure that all the screws are correctly installed and meet the required specifications.

Documentation: The installation process, including depth, torque, and levelling of each pile, is documented for future reference and quality assurance.​

Construction of the house

Immediate progress: One of the advantages of screw piles is that construction of the house can commence immediately after the foundation installation is complete.

Clean-up and site restoration

Restoring the site: After installation, the site is cleaned up, with any excess soil or materials removed. The minimal impact of the installation process means the site remains largely undisturbed. If we needed to add ground screw foundations for decking, fences, carports, or even a garden room, we could have added this during the installation.
