Mainmark methods provide ideal solutions for numerous applications, such as: level correction of sinking floors and buildings; strengthening weak and unstable ground; filling holes, voids and pipes; earthquake remediation; and revitalising ageing infrastructure.


Jet Grouting
Strengthen ground on a massive scale.
Jet Grouting is accomplished with high pressure, high velocity jets located in a grout monitor attached to a drill stem. After advancing to the required depth, the monitor is rotated as it is withdrawn. Simultaneous water-jetting and slurryjetting hydraulically erodes, mixes and partially replaces the soil with cementitious slurry, to create engineered ‘soil-crete’ of high strength and low hydraulic conductivity. Jet Grouting can be performed to great depths and around obstructions. There is no excavation.

Uretek® Resin Injection Technologies
Resin injection technologies for ground compaction, void filling and re-levelling buildings and other on-ground structures.
Uretek engineered structural resin injection raises, re-levels and re-supports sunken building foundations fast, economically and with a minimum of disruption to occupants. Building footings are raised and returned towards level rapidly. The Uretek method – 30 years worldwide proven technology – does not involve demolition or excavation, no water is used and there is little, if any, mess.
