Providing You Peace of Mind
Teretek Resin Injection
This method injects expanding structural resins into very small holes that have been drilled into the concrete slab.
An irreversible reaction occurs as the injected material mixes, causing it to expand and set. The mixture fills any voids caused by unsettling, strengthening and compacting weak ground. Finally, the force generated by the expansion lifts the home where required. We utilise our proprietary engineered resin solution, Teretek®, perfected by Mainmark after many years experience in fixing foundation ground issues and our knowledge of the unique local conditions. It has been used extensively in Christchurch earthquake repairs. Likened to keyhole surgery, this is a non-invasive, cost and time effective solution to get you back to level.
JOG Computer-Controlled Grouting
JOG is a computer-controlled grouting re-leveling method that provides a very gentle lift, over large areas.
A number of small holes are drilled, with grout delivered at multiple injection sites. Layers of grout are built up progressively to lift and ‘float’ the structure at specific points, bringing it back to level. JOG uses a computer-controlled system, delivering a continuous and balanced lift. The JOG method is a non-invasive solution for correcting subsidence of buildings, floors and other structures – it’s a time efficient and cost effective method.
