Slab Lifting

What Sinking Floors and Concrete Slabs Indicate

Sinking concrete slabs are a glaring sign of subsidence beneath your property. It's not merely an aesthetic issue but a symptom of deeper, foundational problems that need immediate and expert attention.

Rectify specialises in resolving sinking concrete slab issues in residential properties through our advanced chemical underpinning process. This method directly combats the root cause of subsidence by strengthening the soil beneath, ensuring a solid foundation for your home.

Our approach is tailored for residential settings, offering a non-invasive, cost-effective solution that minimizes disruption to your household while providing quick and lasting results.

Slab Lifting

Concrete slabs have a variety of configurations, depending upon whether they act as foundation elements or pavements. The method of construction is in part dictated by the expected ground conditions when taking into account the role of the slab and the design loads.
 
Things can go wrong when calculations fall short or when the observed soil performance doesn't conform to the geotechnical classification. Unexpected ground conditions including non-compliant back fill, undetected disturbed ground, erosion and slope instability can all compromise the performance of slabs. Similarly, site maintenance issues involving excessive moisture or drying influences will also create unwanted differential movement where clay soils predominate.
 
Replacement is an option where there are no structures placed upon the slab, however geopolymers offer numerous benefits that allow you to retain the pavement. Not only is the process of injecting structural resin below the slab less invasive, it removes the need for preparatory earthworks and waiting for concrete to cure. Better still, the expanding polyurethane will address the principal reason for subsidence or settlement, that being the failure of the soil. The same holds for structural foundation slabs, where replacement isn't a valid option.
 
Ground improvement is provided through the action of the resin invading fissures and voids, compacting the soil and ultimately adding volume to the soil column. The volume addition acts to lift the overlying element as the product strength is equal to or greater than the soil it is invading. This allows correction of the slab alignment with a more certain expectation of the long term performance, as long as ground conditions are managed appropriately.

What Causes House Foundations To Sink?

A variety of factors contribute to the underlying issues that lead to sinking house floors and slabs, leaning or cracked walls, jammed doors and more.

These issues often stem from changes in the ground beneath a property, leading to soil movement. The impact of these changes can vary significantly depending on the type of ground your property is built on, with certain conditions exacerbating the effects.

As the ground shifts, it can cause buildings to experience subsidence, where foundations or footings lose their support and sink into the weakened ground.

Here are a few of the common causes of house subsidence.

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.
