Void Filling

Here at Geobear, we provide void fill solutions for any size of project, across the UK and Ireland. Typical applications for this process include pipelines and tunnels, but the solution is suitable for almost any void located beneath the ground.

An Effective, Versatile Solution

Geobear’s solution is renowned for its effectiveness and versatility. We fill voids beneath roads, railways, major construction sites, residential properties and more. Whatever the void issue, our injection solutions could help.

Our void filling process involves utilising a specific geo-polymer or a combination of Geobear geo-polymer and a lightweight clay aggregate. The filling is achieved by using lightweight materials that do not impart significant load to the site, meaning our void filling solution will not lead to any negative side effects on the overall stability of the site.

The versatility of our solution means that no matter how hard to reach the area is, we’ll be able to pump resin into it with minimum disturbance to you. We can pump it up to 70m, so our equipment does not have to be directly on the site, giving us even more options for finding the perfect solution.

Minimum Disruption

Once you have commissioned our void filling services, the Geobear team will begin planning the job straight away. We will work closely with you and together we will come up with a schedule that is convenient for you, your family or your business. Our staff have worked on countless void-filling jobs, so they have the expertise and experience to adapt and tailor the solution to you and your building. When it comes to implementation, our team of experts will carry out the necessary work quickly and efficiently, with the utmost professionalism.

An additional benefit is that all of our materials are inert and can be easily excavated, so if at a later date the void needs to be accessed, the geo-polymer can be removed with ease. Where required, we also provide a specialist structural grade void fill solution that can be applied directly or through an injection small hole, providing a non-disruptive solution. This means that your property won’t have to become a loud, obstructive construction site.
