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.

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.

R + R offers void filling solutions for projects of all sizes. 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.

Our methods include slab jacking, permeation grouting, and resin injection, which provide an effective remedy for foundations subsiding. If you notice structural symptoms like cracked walls, jammed doors, or uneven floors, it’s crucial to act swiftly. Ignoring these signs can lead to severe damage, compromising the integrity of the entire structure.

Our void filling techniques also include soil stabilisation to reinforce weak ground and prevent further subsidence. This ensures the foundation remains stable and secure once the voids are filled. By addressing the root causes of foundations subsiding, we help to maintain the longevity and safety of your property.
