Mainmark offers unique, innovative solutions to address site specific ground engineering and asset preservation challenges in the infrastructure, industrial, commercial, civil and mining sectors.
Introducing Teretek: Mainmark’s state-of-the-art engineered resin injection solution.
Mainmark’s proprietary Teretek engineered resin solution is backed by more than 25 years experience resolving complex ground engineering problems. Mainmark technicians have developed methods for raising, re-levelling and re-supporting of any above-ground structure, plus increase ground bearing capacity in the one process. It is a non-invasive process likened to keyhole surgery.Learn more
JOG Computer-Controlled Grouting
A unique process of multi-point, cementitious levelling of large, complex structures by computer-controlled equipment.
JOG computer-controlled grouting enables a level correction without the use of hydraulic jacks and temporary lifting platforms. Neighbouring properties are not affected and product is contained within the site. A very high degree of accuracy is achieved and minimal stress is placed on separate sections of the structures, as all parts are supported and brought up together using small, sequenced injections of high mobility cementitious grout.Learn more
Introducing Terefil®, the most advanced structural lightweight polymer modified cementitious based filler.
Terefil® is used to solve a wide variety of challenges in the geotechnical, construction and mining industries. Terefil® is an advanced engineered fill material providing an excellent solution when granular fills or aggregate material options are too heavy, site access is limited, or project schedules are extremely tight. Terefil® is highly flowable, easily placed, and does not require pre-loading or compaction for settlement mitigation. It will flow into spaces to fill voids and exhibits shrinkage of less than 0.1%.Learn more
Permeation Grouting to create ground cohesion before excavation.
Permeation Grouting is the longest-established and most widely used pressure grouting technique. It helps strengthen sands and gravels, and repairs structural formations in noncohesive soils at depths as great as 60m. The process produces a solidified mass to support increased load and fill voids in the soil. This technology can be used in a number of applications. For example, when excavation is required adjacent to an existing building or structure that is set on noncohesive sandy ground. Or it can be used during swimming pool construction to stabilise sandy, noncohesive subgrade to mitigate it slipping or running into the excavations.Learn more
Introducing Terefirm® Resin Injection – the next generation in ground improvement, liquefaction mitigation and bearing capacity enhancement solutions.
Remediating structures affected by serious ground issues, such as liquefaction, poor compaction or settlement, has up until now been a complex process. Weak ground can compromise building foundations and footings, putting the structure at risk of collapse. Ground improvement solutions that are currently available are limited, highly invasive, costly, time consuming and messy. If the ground improvement work requires a building tenant to relocate, the interruption to business can add further losses to both the business operator and building owner.Learn more
Shotcrete and Gunite
Pneumatically sprayed wet and dry mix concretes
Shotcrete is a process where a modified wet concrete mix is pumped down a delivery line and sprayed onto a surface through a nozzle using compressed air as the propellant. *Gunite, on the other hand is a dry concrete mix where water is added at the nozzle also using compressed air as the propellant. Both shotcrete and gunite can be applied vertically and overhead, do not require formwork and are more versatile and efficient alternatives to traditional concrete cast-in-place methods. Mainmark utilises both wet or dry mix shotcrete concrete processes, depending on the site requirements.Learn more
Specialised Resins, Gels and Coatings
Mainmark offers advanced, site-specific solutions for revitalising, sealing, protecting and structurally reinforcing ageing or damaged buildings and infrastructure including tunnels, shafts and basements impacted by weak ground and water ingress.
Complementing the company’s wide variety of ground engineering solutions and technologies, Mainmark’s range of specialised resins, gels and coatings can help to rectify and preserve structures within the commercial, industrial, residential, heritage, civil engineering, infrastructure and mining sectors. Products and applications include engineered coatings and linings for large pipes and utility services; high performance water control treatments that can stop fast flowing water quickly in construction and civil projects, as well as in emergency situations; and waterproofing solutions to seal and stabilise water ingress in dry or water-bearing conditions.
Mainmark’s industrial strengthening solutions provide concrete and steel coatings for building and infrastructure protection, precisely designed and engineered for site-specific needs. All Mainmark solutions are cost effective, quick to apply and non-invasive.Learn more
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.Learn more
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.Learn more
Innovative concrete reinforcement technology for high trafficable surfaces.
Ultra-Panels are high-tech, precast concrete panels that can eliminate the need for resurfacing concrete in marine, road, public infrastructure, agriculture, defence, manufacturing, and mining environments.Learn more
The world’s most advanced platform for easily measuring and analysing the performance of structures to determine the cause of damage, risk of further damage, and overall structural stability.
Mainmark’s geotechnical engineering experts use STRAAM nondestructive ground monitors to conduct a Structural-Cardiograph (SCG), which establishes the building’s dynamic signature and provides real-time reports that accurately assess the stiffness of a structure and changes in the capacity of the structure due to subsidence, ageing, earthquake damage, or other activity. STRAAM technology can also aid in assigning liability for the purpose of insurance or litigation, and help to manage assets and occupant safety more effectively.Learn more
