Mainmark offers unique and innovative engineered products and solutions

TERETEK® RESIN INJECTION SOLUTION Our proprietary two-in-one solution that delivers both improved ground bearing capacity and re-levelling, backed by a 50-year product warranty. Teretek® engineered structural resin injection raises, re-levels and re-supports sunken building foundations fast, economically and with minimal disruption to occupants. Building footings are raised and returned towards level rapidly, without the need for expensive demolition or excavation.

JOG COMPUTER-CONTROLLED GROUTING This unique computer-controlled system is extensively used for re-levelling large and complex structures, such as multi-storey residential and commercial buildings.

TEREFIRM® RESIN INJECTION FOR GROUND IMPROVEMENT Mainmark’s Terefirm® Resin Injection technique can deliver substantial benefits as a viable, low impact solution for ground improvement to address at-risk buildings and structures susceptible to weak soil conditions. The solution uses proven, scientific testing prior to and after application to validate a required geotechnical outcome. Terefirm® has been extensively researched and tested for use in earthquake prone regions where property owners are grappling with damaged buildings and structures affected by seismic liquefaction.

TEREFIL® Our advanced structural lightweight polymer modified cementitious grout, Terefil®, can solve a wide variety of geotechnical challenges in the construction, infrastructure, and mining sectors. This versatile engineered material is ideal for use as a fill in situations where cellular concrete, foam concrete or foam cement would otherwise be applied. T

PERMEATION GROUTING Creates ground cohesion before excavation. This well established and widely used pressure grouting technique helps to strengthen sandy soils and unstable gravels, and repairs structural formations in non-cohesive soils at depths as great as 60m.

SPECIALISED RESINS, GELS AND COATINGS

Mainmark specialises in 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.

As a world leader in innovative ground engineering solutions and technologies, Mainmark offers a range of specialist applications for rectifying and preserving structures within the commercial, industrial, residential, heritage, civil engineering, infrastructure and mining sectors.
