FAQ’s

Our technologies

Our innovative leading technologies can raise, re-level and re-support sunken homes, buildings, floors and roads.

What is Teretek®?

Our Teretek® technology provides a solution to address subsided structures, improve ground, and fill voids.

Re-levelling: Using our specialised expanding resins, Teretek® is a reliable method to lift and level structures.

Ground Improvement: Teretek® is used to deliver ground improvement solutions beneath existing structures.

Void Filling: Teretek® is well-suited for addressing smaller voids found under concrete slabs.

What is Terefil®?

Our Terefil® technology provides an advanced lightweight cellular concrete for soil replacement, large void filling, and pipe abandonment.

Advantages of Cellular Concrete: Cellular concrete stands out for its unique properties, catering to a wide spectrum of applications.

The Fluidity Factor: One of the standout attributes of cellular concrete is its high fluidity. This material can be pumped over long distances, filling gaps, trenches, or voids.

Soil Replacement: In a ground improvement application, Terefil® is used to create a lightweight raft prior to building construction.

What is JOG?

Our JOG technology is a state of the art, computer controlled, multipoint injection system.

Where Technology Meets Grout Injection: The technology uses cementitious grouts with controlled set time structures, from residential homes to large commercial buildings.

How JOG Operates – Coordinated Precision in Action: JOG operates through a sophisticated system of interconnected injection ports, managed and sequenced by a central computer.

What is Permeation Grouting?

A Non-Disruptive Alternative To Traditional Underpinning in Sandy Soils.

Stabilising granular soil prior to planned excavation and increasing the bearing capacity of the treated zone, it fills the voids between the soils and bonds the particles together. This creates a solidified mass that can support increased load, stabilise sunken structures and create temporary shoring solutions.

What is Jet Grouting?

Jet Grouting is accomplished with high pressure, high velocity jets located in a grout monitor attached to a drill stem. It uses a complex process of water-jetting and slurry jetting which produces an end result of ‘soil-crete columns’ with high strength and low hydraulic conductivity.

What was the Uretek method?

The Uretek ground engineering and grout technologies were based on the expansive power of multi-component mixtures of structural geopolymer resins and hardeners.

In the past Mainmark used the *Uretek resin injection methods. This expanding resin was primarily a slab lifting technology and had been used extensively for raising, re-levelling, re-supporting and strengthening moving and sunken structures on or in the ground.

Building on our experience of raising, re-levelling and re-supporting structures and correcting foundation ground issues, combined with our knowledge of the unique local conditions, Mainmark developed our proprietary Teretek resin injection solution.

What type of structures can Mainmark technologies be used for/on?

Mainmark methods provide ideal ground engineering and asset preservation solutions for numerous structures, of varying size and type, including residential, commercial, infrastructure, heritage, civil and mining projects.

We offer methods such as level correction of sinking floors and buildings, strengthening weak and unstable groundfilling holes, voids and pipesearthquake remediation, and revitalising ageing infrastructure.
