GROUND IMPROVEMENT

If the soil is not stable and strong enough, there is a risk that the building or structure may subside. Groundtek has a solution to improve and stabilise the ground and the bearing capacity directly under the foundation without excavation, vibrations or other disturbances.

Cause subsidence


Common causes

done

SUBSIDENCE CAUSED BY COMPRESSIBLE LOAM;

SUBSIDENCE CAUSED BY BACKFILLING;

done

LEAKING OR BURST WATER AND SEWER PIPES WHICH CAUSE SUBSIDENCE PROBLEMS;

INADEQUATE GROUNDWORK;

EXCAVATION NEAR A BUILDING CAUSING SUBSIDENCE IN THE GROUND;

done

SETTLED FLOORS;

done

VIBRATIONS FROM HEAVY TRAFFIC;

On top of all that, there’s also the extensive repair costs which you may have to deal with if subsidence is left to get worse. Structural damage to a building, its wiring and pipework can all potentially be enormous financial costs. Importantly, these extensive repairs dwarf the cost of Groundteks quick, clean and effective ground remediation solutions. Untreated subsidence can lead to significant loss of property and structural value, as well as costs to your business from an inability to use your premises or structures for their planned purpose. Why take the risk with your property? Do not leave it too late—it’s not worth it.

Clean and easy - no need to move out

As we just need to drill a few holes to inject the geo-resin, there's no need to move out and usually we don't even need to do work inside the property;

No need for costly and disruptive groundworks

We don't need to dig new foundations or sink piles so you save time and money (and we won't have to dig up your garden);

The Solution: A Resin Injection Process

Our ground improvement solution is an engineered procedure, whereby the bearing capacity of foundation soils is either continuously improved down to considerable depths or just at one specific depth, by the injection of expanding geopolymer resins. The procedure allows densification and compaction of the soil directly under a building, without the need for excavation, vibration or mechanical force.

Groundtek ground improvement can be a fast and cost-effective alternative to piling and underpinning. It’s achieved by the controlled application of the forces generated by the expansion of unique Groundtek geopolymer. Ground improvement, carried out by the team at Groundtek, is a convenient and reliable process which enables customers to continue their normal operations during remediation works, saving you time and money.

Our solution subsidence soil

Before the repair work begins Groundteks's team carefully investigate the soil under the foundation. The results of the test will show how deep the geopolymer should be injected and which types of geopolymer should be used to maximise the bearing capacity of the ground.

When you know the soil conditions, small holes are drilled through the foundation or the slab. Injection tubes are installed into these approximately 2cm diameter holes. Through these tubes the geopolymer is injected as deep as is necessary. Firstly the geopolymer, which is in liquid form, penetrates the voids that are in the soil and thereafter expands and seals the surrounding soil.

The injection process is monitored by laser, which indicates when the soil has reached the desired bearing capacity. The geopolymer that is injected in the soil hardens in about 15 minutes, and the desired bearing capacity of the structure is reached.

The Benefits of Our Solution

Office building soil improvement
  • done Our systems and solutions offer an almost distraction-free site allowing residential, business and commercial buildings to keep running with no downtime. This saves you both time and money as everyday operations can continue running at full capacity.

  • done Our systems are built on efficiency. Every step of the stabilisation process is expedited and some projects can be completed in just a single day. Some of the alternative subsidence and ground repair methods can take weeks and even months to finish;

  • done Our systems provide a new level of support to uneven slabs, repairing damages that have occurred over a number of years. We offer services for all types and sizes of building. Groundtek can revive foundations back to their original quality and capacity, no matter the type or purpose of the building or structure;

  • done Unlike traditional techniques, our geopolymer approach doesn’t rely on an abundance of hydraulic pressure which can sometimes get a little uncontrollable. Instead, boundaries are raised with complete control resulting in a much-reduced chance of damaging or breaking slabs;

  • done Thanks to the advanced nature of Groundteks solutions, buildings don’t always have to be lifted to be repaired. In some cases, a number of very small sized holes can permit geopolymer resins to be injected through floor coverings and finishings should lifting not be a feasible or necessary option;

  • done All services, solutions and products have been officially certified as having no negative impact on the environment. They also require no excavation or disturbing of laying ground resulting in a more eco-friendly underpinning method than the excavation-heavy alternatives;
