Void Filling and Sinkholes

Voids or sinkholes are holes that appear in the soil matrix due to natural erosion, geological change, or digging activity in the area. Digging activity includes standard construction work, as well as mining or building.

A void or sinkhole can be a small hole needing simple soil stabilisation and filling or a more significant issue that results in cracked walls and issues with the drainage systems of the structures above. A void or sinkhole can also manifest in major collapses. These larger holes require a more industrial solution and additional support to prevent further occurrences.

Early signs of voids under concrete or sinkhole issues include jammed doors and windows, resulting in structural damage if not addressed quickly. If you are dealing with voids beneath a building, you will require void fill solutions to address foundation repairs and resin injection where necessary. Raise + Relevel can help.

It is essential to address a manmade void as these tend to be more severe. For example, those voids left behind in pipe abandonment or similar works must be filled. A void underground can result in soil destabilisation, water ingress, and subsidence, which increases the likelihood of fluids leaking in the surrounding area, which can cause ground collapse. Filling voids quickly, safely, and accurately is of the utmost importance to the surrounding area.

What You Need To Know

If you have a void or a sinkhole, you need to take steps to correct the issue. This is where you fill the voids to stabilise the area. Void filler comes in many forms, whether you prefer a chemical solution or a cementitious grout.

We don’t employ salespeople, so the person who visits your site to provide details of the job and a quote will also be the person tackling your project. Our team is experienced and knowledgeable enough to advise you on which solution is right for your particular void or sinkhole.

There are many reasons for sinkholes and voids. When there is infrastructure work in the area, whether it is building or mining, it can result in soil issues. There are also natural occurrences, such as flooding and earthquakes, that can result in major voids and sinkholes. These can appear suddenly but often develop over time. If there are mining operations in the area, there is land slippage, abandoned pipelines or tanks, water ingress or the soil is improperly filled or poorly compacted, there is a higher risk of voids and sinkholes.

Why Do You Need Void Filling?

The purpose of filling sinkholes and voids is to stabilise the ground around them. Whether it’s a tunnel, bridge road or a decommissioned structure, the solution aims to stabilise and re-support.

The R + R team has handled countless jobs filling voids, and we have the experience and expertise to tailor a solution to every situation. We handle work quickly, efficiently, and professionally and we always aim to provide you with the most cost-effective solution possible. While many people immediately look to a slurry fill as the cost-effective option, we believe in some circumstances polyurethane foam is more cost-effective.. Different fill materials have different performance profiles. We suggest investigating the right solution for your situation.

Our range of void fill materials can address tunnels, pipelines, voids, sinkholes, basements, and any other infrastructure issues you may face. Our solution is so versatile, it doesn’t matter how difficult the issue is to reach – we can pump the void fill material without causing too much disruption.

Call Raise & Relevel Today For Void Filling & Sinkholes

The only way to address an unstable, unlevel or dangerous void or sinkhole is to fill it. While slab jacking is the solution, we offer to relevel a structure. As it addresses existing concrete slabs, there is no need to pour fresh concrete, which means it provides a cost-effectiveness that many other solutions do not. Our team simply pumps the resin as means of filling voids under concrete. However, some issues require us to fill voids in concrete more industrially.

Concrete void filling protects public buildings and can address unlevel buildings. Whatever your recent project entails, reach out to the R + R team in Sydney, Melbourne or Brisbane/Gold Coast to discuss your options when it comes to drainage solutions, re-levelling, permeation grouting, and beyond.
