Resin injection underpinning
We lift, level, and stabilise structures through precise resin injection underpinning, restoring foundation strength quickly.
Resin injection underpinning

When a building is experiencing subsidence, resin injection underpinning is a fast and reliable solution that can save time and money compared to traditional underpinning.
Subsidence occurs when the ground sinks unexpectedly. This can be due to:
Changes in the soil moisture levels because of the climate, which can cause the ground to shrink or swell. This can be a particular problem in the clay-rich soils found in areas like Dublin, Meath and Cork
The roots of nearby mature trees, which can have a similar impact because these suck moisture from the ground, again causing it to shrink
Heavy traffic local to a property can cause sub-surface vibrations which can result in subsidence
Leaking drains which wash away soil particles, particularly in sandy soils, can destabilise foundations
Historical land use such as mining or peatland drainage in rural areas can lead to ground settlement
Resin injection underpinning vs traditional underpinning

Traditional solutions to subsidence involve digging out under the foundations of a building and then adding piles or mass concrete. The process is complicated and time-consuming and can take weeks or months to complete and, while work is carried out, the building must often be unoccupied.
Mainmark’s Teretek® resin injection is an innovative and proven alternative to underpinning. With resin injection there is no need for excavation, instead we drill small 16mm diameter holes into the ground under the building's foundations (and if required through the floor slab) to enable tubes to be inserted to allow an inert resin formulation to be injected. The resin fills any voids, improves the load bearing capacity of the ground. We can even gently raise or re-level a building or structure through the controlled injection of resin.
Mainmark also offer JOG computer-controlled grouting, which is another option for overcoming subsidence. Both solutions have been effective in dealing with subsidence in a wide variety of projects including factories, offices, public buildings, heritage projects and retail centres and infrastructure.

Warehouse subsidence treatment and concrete floor re-levelling without operational disruption
In Ireland, subsidence tends to occur where the original foundations of a warehouse are unsuitable for the ground it has originally been built on. This can cause foundations to sink and lead to the differential settlement of concrete floors, driveways and areas of hardstanding. If the concrete floor of a warehouse drops, causing it to slope, the facility can fall below safe operational limits.
When equipment, vehicle movements and foot traffic rely on level, stable slabs for effective operations, a dependable ground improvement solution is essential. Mainmark can fill large voids and large holes and re-level and re-support sinking slabs and sinking floors quickly and cost effectively using state-of-the-art, non-invasive solutions to ensure productivity is maintained.
We use a range of fast and cost-efficient solutions to improve weak or sinking foundations without compromising business operations.

Effective solutions for social housing subsidence
Subsidence can impact the structural integrity of a property and affect the safety and wellbeing of residents. It can also have financial implications for the housing provider.
Traditionally, resolving subsidence would have required underpinning or piling beneath the property. This can be a complicated, time-consuming, and expensive process that often requires occupants to vacate the property while the work was carried out.
As experts in dealing with social housing subsidence, our Teretek® resin injection and JOG computer-controlled grouting are innovative alternatives to mechanical jacking, underpinning and piling. These innovative, non-invasive technologies can resolve subsidence issues in both houses and multi-occupancy properties quickly and with minimal disruption to the occupants.

Effective solutions for subsidence in heritage buildings
Historic buildings often suffer from ground settlement or instability. In Ireland, this can be down to ground conditions changing over time or because the building’s original foundations were insufficient. Whatever the cause, a building's historic importance makes it critical that remedial work is undertaken with minimal intrusion.
Mainmark's non-invasive, cost effective and time efficient re-levelling methods can raise and re-support historic buildings and homes. Our Teretek® resin injection and JOG computer-controlled grouting are innovative alternatives to mechanical jacking, underpinning and piling. With no excavation required the building can often continue to be used during the remediation works.

Remediating road subsidence
Regular maintenance and replacement of aged road infrastructure is essential for Ireland's roads to sustain heavy traffic. Since 1989, Mainmark has provided its well-established Teretek® Resin Injection technique as a fast, non-disruptive, and economical solution for re-levelling subsided pavements and structures and strengthening subgrade soils associated with pavement failures.
Some of the more common applications for the remediation of roadways with resin injection are:
Filling voids directly beneath pavements to reconfirm support and limit deflection and deterioration.
Raising subsided pavements to re-establish design levels, maintain drainage or camber gradients, and restore a safe and comfortable ride for motorists.
Re-supporting, void filling and raising bridge approach and relieving slabs.
Providing targeted ground improvement to weak sub-grade soils.
Mainmark's Teretek® Resin Injection has been qualified, tested, and adopted by road authorities across the world. It offers a unique method for addressing bearing capacity issues and voiding, which is common in the ground beneath aged infrastructure while avoiding high costs and road closures associated with sub-grade and pavement removal and replacement.

Teretek® – resin injection for treatment of subsidence
Teretek® is an engineered solution for re-levelling commercial properties, infrastructure and residential homes. Teretek® works like keyhole surgery for buildings. Small holes are drilled under the foundations to enable injection tubes to be inserted. These tubes enable Mainmark’s proprietary, environmentally inert resin to be injected at strategic points beneath the foundations. The resin fills any voids and improves the stability of the ground. It can also be used to lift and re-level the structure.

JOG computer-controlled grouting for treatment of subsidence
JOG computer-controlled grouting is a multi-point injection technique. This technology typically uses cementitious grout to re-level structures. It can be used to effectively treat all types of buildings suffering subsidence by injecting cementitious grout under the foundations using computers to accurately control injection amounts in predetermined locations.
