Void Filling/Sink Holes And Erosion Remediation With Soil Stabilisation

Securing Foundations, Enriching Futures. Specialising in Resin Injection Underpinning.

Void Filling

Sinkholes and voids can form due to natural or human activity. The main causes of voids or sinkholes are:

  • Natural soil processes causing shifts and cave formation or voiding. That is underlying weak soils or dissolution of rock may cause natural formations of deep caves/voids leading to surface depressions (sinkhole) or deep shafts (voiding).
  • Flooding or rainfall leading to water migrating through soil due to natural flow paths or poor drainage installation (human activity), causing migration of soil and erosion due to stripping away silts and smaller particles and saturating the clay causing weakened soil and eventual loss of bearing and collapse.
  • Abandoned mineshafts with capping layers: Mineshafts with capping layers rely on capping layer for support over the abandoned shaft. If this capping layer is compromised and destabilised, then the mineshaft will be exposed causing soil collapse and exposure of large void.
  • Earthworks reinstated with poorly compacted backfill: Poorly compacted backfill will naturally be aerated and have pockets of air and water. As the backfill consolidated under its own weight, or even worse under the weight of a floating slab, it will start to consolidate causing surface depression.

If due to above scenarios, voiding or sinkhole formation were to happen near or under your property, it may cause damage due to loss of bearing. If left untreated, it will lead to worsen, causing structural damage to the footing and structure above.

Our experts are dedicated to maintaining the health of your home's foundation with meticulous attention to detail using the latest in chemical underpinning technology. By preventing future settling and addressing existing issues, we extend the life, and enhance the comfort, of your home.

We’re committed to delivering a service that not only meets but exceeds your expectations. Trust us to keep your home strong and your family secure

Getting to the Root: Identifying Erosion

Unstable, loose soil and erosion can be detrimental to a number of structures including buildings, bridges, roads and underground civil infrastructure. It can lead to settlement and damage to the structure due to large voids beneath it and loss of bearing of foundations, causing instability of structure above.

Soil Stablisation: Resilience Through Resin

Using patented ultra-low viscosity polyurethane resins, voids can be filled, soil consolidated, erosion halted and soil bearing improved.

Solutions we can provide include but not limited to:
-Soil permeation grouting
-Stabilising loose sand and soil
-Sinkhole remediation
-Filling voids behind concrete structures
-Cutting off high flow leaks
-Cutting off underground water flows
-Increase load bearing capabilities

Permeation Grouting using Polyurethane can ensure stabilisation, consolidation and binding of soils. Through permeation injection of polyurethane resin in a gridded/sequenced pattern creates a solid mass of soil and rigid resin (ideal for silty and sandy soils).

The displacement of water and the resulting solid soil/resin mass reverses the erosion process and improves soil stability and soil bearing capacity.

Very Professional

Very professional. Explained everything to me and answered all my questions. The guys were always on time and cleaned up everything when they left, and they were friendly and polite.

Professional & Clear

Professional and clear advice, all services undertaken in a planned and timely manner. At the moment all seems well - but a bit early to confirm definitively

Rectify will be your best choice if your property has any cracks need to be fixed. Josh came to quote our job on this windy day. He explained anything after checking the level. Really impressed with his knowledge and honesty. I will keep monitoring the cracks on my walls and garage floor. I will definitely get this guy back if they get worse. But for now it seems OK. Thanks Josh again!!

The team turned up on time and carried out the work efficiently. Although my cracked render didn't close up totally, I'm happy in the knowledge that the ground is underpinned. When I get the cracks repaired, they are unlikely to crack again. Thanks again, guys.

I cannot recommend this company enough, they were absolutely incredible! From my first meeting with Phil I felt assured that he knew exactly what he was talking about and he made the stressful situation we were going through so much easier. We then had Sam come out and he was fantastic and again put us at ease so it was a no drainer that we would be going with them. The team that came and completed the job were again so amazing, professional and friendly. They left the house so clean and made sure to inform me of what was happening every step of the way. Thank you to the Rectify team for an amazing experience from start to finish.

Rectify was really prompt with their service, did a great job explaining the details of the problem, the work involved, and the process to correct it. The resin injection process is very precise and can be targetted with great accuracy. The work itself didn't take long at all and the turn around time was great; having the work done about a week after agreeing to the quote. Highly recommend.
