Paul Jackson used Geobear to stabilize a bungalow and conservatory in Northwich, UK. Geobear completed the underpinning process in just four hours, significantly faster than the estimated three months for traditional concrete methods. The geopolymer injection provided a lightweight, non-intrusive solution that protected a nearby retaining wall from structural collapse while leveling the building.

At a glance

Primary Use Case
Underpinning a bungalow and conservatory near a sensitive retaining wall.
Reported Result
Property stabilized and lifted without the weight of traditional concrete.
Time to Value
4 hours for on-site work; 7 weeks for the total end-to-end process.
The guys were here and within four hours they'd underpinned the property.
To actually put concrete underneath this building would have put so much strain onto that retaining wall it probably would have ended up collapsing.
I would definitely recommend Geobear as a quicker, faster and more professional way.

The interview

What was your overall experience with the speed and professionalism of the Geobear team?

The time it takes to get it done—I mean, the guys were here and within four hours they'd underpinned the property. They were in, and the guys were good, they were very professional. They monitored the whole property and I felt very confident that they were doing a very good job.

Who are you and where is the property located?

I'm Paul Jackson, and I live in Cuddington in Northwich, UK.

What specific structural challenges were you facing with your property?

I bought a bungalow which has got a conservatory, and a retaining wall on the opposite side. This is a house that's got a slope-away garden that goes down 20 foot with a retaining wall six foot behind the conservatory about seven or eight foot away. My concern was traditional underpinning with using cement concrete underneath would have been too heavy for the retaining wall.

Why did you choose Geobear's geopolymer solution over traditional concrete?

To actually put concrete underneath this building would have put so much strain onto that retaining wall it probably would have ended up collapsing. They actually injected the product underneath, and it wasn't heavy at all, but yet it gave us the ability to underpin the property and stabilize it.

How did Geobear assist with the underlying cause of the subsidence?

Generally, the most common cause of subsidence is leaking drains. They were instrumental in recommending drainage companies that work with Geobear. I had a drainage survey done because the resin that they use, if you don't get the drainage done, can leak into there as well.

What was the total timeline for the project from start to finish?

I think it was about seven weeks, right away through with the drainage companies, and everybody coming on site and finishing the job.

What kind of preparation did you have to do before the work started?

I had to take the brick work around the building away, which is the patio, because I need to drill through and down into the sub-core. I had to take some flooring up on the inside of the property, the area that I wanted underpinning, so it could monitor all the component parts of the building. But other than that, preparation was very simple really.

How does the cost and intrusion of Geobear compare to other methods?

I would say to people is one, it's cheaper. Two, it's certainly not as intrusive as traditional ways of underpinning. Three, the cost is really, really good compared to concrete etc, and the time it takes. If I had underpinned [traditionally], it probably would have taken me three months.

Frequently asked

Will traditional concrete underpinning damage a nearby retaining wall?

Paul Jackson was concerned that the weight of cement concrete would put too much strain on his garden's retaining wall, potentially causing a collapse. He chose Geobear because their injected product is not heavy, allowing for stabilization without adding excessive mass to the slope.

How long does the Geobear underpinning process take compared to traditional methods?

According to Paul Jackson, the actual underpinning work took only four hours. He estimated that traditional concrete underpinning would have taken approximately three months to complete.

What preparation is required before Geobear arrives?

Paul Jackson noted that preparation was simple but required removing some patio brickwork and internal flooring to allow for drilling and monitoring. He also emphasized the importance of a drainage survey to ensure no resin leaks into the pipes.

So I bought a bungalow which has got a conservatory, and a retaining wall on the opposite side. My concern was traditional underpinning with using cement concrete underneath would have been too heavy for the retaining wall; needed to find a solution. I went on the internet, found GeoBear, looked at a I found that their process is quite unintrusive to a certain extent. You've got to prepare for it, the way that they injected the thing building, and lifted it up in some cases, or not as a case maybe, it gave me confidence. This is a house that's got a slope-away garden that goes down 20 foot with a retaining wall six foot behind the conservatory about seven or eight foot away. So to actually put concrete underneath this building, would have put so much strain onto that retaining wall it probably would have ended up collapsing. They actually injected the product underneath, and it wasn't heavy at all, but yet it gave us the ability to underpin the property, and stabilize it, and the guarantees that go with it, as well. I think they were instrumental in a couple of things. First of all, I had a drainage survey done because the resin that they use, if you don't get the drainage done, can leak into there as well. Generally, the most common cause of subsidence is leaking drains, and I had to have that done. They recommended drainage companies. I used them. They work with GeoBear. I think it was about seven weeks, right away through with the drainage companies, and everybody coming on site and finishing the job.
