Mainmark UK | Teretek® Resin Injection | How it works?

Introducing Teretek®: Mainmark’s new state-of-the-art engineered resin solution Teretek is a unique two-in-one solution that delivers both ground improvement and re-levelling and comes backed up by a 20 year product warranty. It increases ground bearing capacity, fills voids, and can mitigate soil liquefaction, all at a fraction of the cost of traditional underpinning and ground engineering methods, and with no detrimental effects on the environment. Mainmark technicians select a number of injection points under the structure in a process similar to keyhole surgery. The Teretek expanding polyurethane resin mix is then injected through very small tubes into the ground beneath the footings. On entering the ground, the components mix together and expand by chemical reaction, which strengthens the ground and re-levels buildings quickly and with minimal disruption. Our polyurethane injection underpinning solution is tightly-controlled with constant monitoring by laser level. Wherever possible, the injection is done from outside the building or house through 16 mm diameter tubes. When injection has to be carried out inside, it is done through very small 6mm diameter tubes which are placed as inconspicuously as possible. This results in minimal intrusion into the property and minimal interruption to the occupants, effectively underpinning by non-invasive expanding resin injection. In most cases, building occupants are not required to move out or move any furniture during the ‘home lift’ process. The process is extremely quick: most house re-levelling and slab lifting takes less than a day, and concrete driveways and slabs can often be driven on within hours. Teretek is ideal for many commercial, industrial, civil and mining applications, as well as residential.
