What Are Non-Invasive Building Foundations?

Non-invasive building foundations are a modern alternative to messy, time-consuming concrete footings. They support short- and long-term portable building installations without the need to excavate and pour a concrete foundation. Designed for speed, flexibility and a reduced impact on your site, they are becoming increasingly popular in modular building projects where timelines, access issues and a desire to lessen remediation works are an issue.

In this blog post, the Jackpad® team has set out to explain how non-invasive foundations work, where they’re used and why they’re becoming the practical choice for many projects. Let’s get started.

Understanding Non-Invasive Foundations

In construction terms, what we’re referring to when we say ‘non-invasive foundations’ is a way of supporting buildings and structures without the need for excavation or significant alteration of the site. So no digging, no concrete and in almost every case, very little site remediation at the end of a project.

Non-invasive foundations instead sit on the ground surface and distribute the loads across it safely, provided the necessary ground-bearing capacity is achieved. This reduces site disruption, speeds up installation and makes it easier to remove foundations when a project ends.

The Jackpad® System

The Jackpad® system is a non-invasive foundation option that allows modular buildings to be safely installed on site up to three storeys. Each three-part Jackpad® unit is made up of a recycled plastic support block, steel adjuster and incremental packers that overcome the fall of ground on uneven sites. Together, they form the system to support the modular building loads. Installed without excavation or concrete, they support short- and long-term modular building installations and can be removed, restored and reused at the end of a project.

How Non-Invasive Foundations Work

The fundamental job of non-invasive foundation systems like Jackpad® is to take the modular building point load and spread it over the wider area of the incremental packer at the base of the system.

This approach enables the Jackpad® system to be used without the delays and uncertainties associated with traditional concrete foundations. As long as suitable ground-bearing capacity is achieved, Jackpad® offers a practical and proven alternative.

For modular buildings in particular, Jackpad® provides a proven way to avoid excavation, curing time and weather-dependent concrete pours. Installation of the Jackpad® system typically follows a simple process:

• • A site survey is carried out to ascertain ground levels and site access.

• • Foundation components can be placed directly onto most surfaces, with minimal to no ground preparation required.

• • The chosen system is adjusted and fine-tuned to achieve accurate levelling beneath the modular building.

• • With no excavation or concrete curing time required, installation can take place quickly and in most weather conditions. Typically up to 100 pads a day can be installed depending on site specifics.

• • At the end of the project, non-invasive foundations can be removed with little disruption, significantly reducing remediation time.

The Jackpad® system is designed to support modular building installations of varying sizes. We match the various Jackpad setups with the client’s project specific loads for both individual modules and larger multi-module configurations.

Advantages of Non-Invasive Foundations Like Jackpad®

Speed of Installation

Non-invasive foundations remove the delays caused by excavation, concrete pouring and curing. With Jackpad®, installation is not reliant on curing times or weather windows, so they can be installed far quicker helping to keep project timelines on track.

Environmentally Friendly

By avoiding concrete and extensive groundworks, non-invasive foundations significantly reduce waste and site disturbance. Jackpad® takes this further with systems designed for repeated use and recycling, helping lower environmental impact across multiple projects.

Health and Safety

Another benefit of our foundation systems is the improvement of on-site health and safety, by removing the need for specialist tools and reducing permit requirements. With less groundwork and disruption, risks are minimised. All processes are managed in line with manual handling guidance and trip hazard prevention standards.

Reusability and Flexibility

Non-invasive foundations can be removed, reconditioned and reused across multiple projects. With Jackpad®, this flexibility is built into the system, making it ideal for changing site layouts, short- and long-term installations, simplifying crane positioning, worksite accessibility and projects where buildings may need to be relocated.

Costs

Faster installation, reduced ground prep and minimal remediation works all contribute to lower overall costs. By removing uncertainty around weather delays and end-of-project clean-up, Jackpad® helps make foundation costs more predictable.

Making that initial larger investment by buying from Jackpad®, means that you have a foundation option that can be used again and again, reducing long-term costs. Alternatively, hiring can reduce your upfront costs and simplify site setup.

What Buildings Non-Invasive Foundations Are Used For

Non-invasive foundations provide a modern alternative to traditional concrete foundations for many projects. For modular buildings in particular, systems like Jackpad® are widely used across a range of applications, from short- to long-term installations. There are several scenarios where they provide the only viable alternative to traditional options:

• • Modular Buildings: Providing fast installation and accurate levelling using surface-based systems like Jackpad®.

• • Short-Term and Semi-Permanent Structures: Ideal where buildings are required for defined periods, allowing easy installation, removal and reuse.

• • Environmentally or Historically Sensitive Sites: Avoid excavation and permanent ground damage, helping meet planning constraints.

• • Poor Access or Uneven Ground: Adjustable systems such as Jackpad® handle slopes, enabling installation where other methods are impractical.

• • Projects Requiring Relocation or Expansion: Foundations can be adapted, moved or reused, supporting evolving site requirements.

For modular projects of all sizes, the Jackpad® system offers a flexible, reliable and practical alternative to concrete.

The Future of Non-Invasive Building Foundations

Modular construction continues to grow in popularity, and non-invasive foundation systems like Jackpad® are helping deliver faster, cleaner and more sustainable solutions.
