Global markets continue to embrace Mainmark’s innovative ground engineering solutions
07 August 2019
Mainmark has been providing specialist ground engineering and asset preservation solutions since 1983.
Originally founded in Australia, our local operation
has grown into a global enterprise with offices in New Zealand, the UK,
Japan and Thailand.
Mainmark’s global standing received a boost after it won a major
Ground Engineering Award in 2016 for its work in re-levelling
the
Christchurch Art Gallery following the 2011 earthquake events. This
was testament to the exceptional level of engineering expertise and
geotechnical innovation that Mainmark continues to uphold across its
global business operations.
The business has a history of innovation and doing what others can’t. It
continues to invest significant resources into developing new ways to
address a variety of unique ground engineering problems such as
Terefirm™ Resin Injection, a proven, non-invasive soil densification and
liquefaction mitigation technique that can be easily applied beneath
existing structures. This initiative was undertaken as part of the
Christchurch Red Zone research trials, in partnership with New Zealand’s
Earthquake Commission (EQC) and the Ministry of Business Innovation and
Employment (MBIE), and the outcomes are now included in the MBIE
Module 5: Ground Improvement of Soils Prone to Liquefaction.
With a reputation for unwavering commitment to research, development,
testing and innovation, Mainmark has also aligned with world-renowned
experts such as Dr Alan Jeary, an industry pioneer who co-created
STRAAM
monitoring technology, to complement its
business offering. STRAAM was used to help preserve the White
Rabbit, a valuable heritage-listed building in central
Auckland, by monitoring the structure for building movement prior to and
during construction.
In the growing UK market, Mainmark has completed a number of impressive
projects that solve a range of issues relating to poor soils. The
commercial sector represents a large proportion of re-levelling projects
in this region, including a large factory and warehouse
located in Sheffield which had suffered severe differential settlement.
The building was built on a former coal mining site
with highly reactive compacted fill soil that was susceptible to voids
and subsidence, and was subsequently suffering from severe cracking and
sloping floors, that were out of alignment by up to 156mm. Maimark
remediated the structure in stages using a bespoke engineered solution
including use of our proprietary JOG Computer-Controlled Grouting. A
robotic survey station was also set up to provide real-time lift data to
monitor the grout injection process, which required injection rods to be
inserted at 112 locations to a depth of 6m. This highly complex project
was completed in 42 days without impacting the business, which continued
to operate while the works were carried out.
More recently, the UK team remediated the Traders Coffee
site in South London. The commercial business unit had been built on
poorly compacted ground and the weakening soil had compromised the
building’s structural integrity, which had worsened after the addition
of a mezzanine floor. Ground subsidence had been progressively worsening
due to poor drainage and an overflowing gutter. Previous owners had
attempted to solve the issue by pouring additional layers of concrete
over the affected floor area, which had dropped by approximately 120mm.
This measure did not, however, address the underlying ground subsidence.
Maimark’s UK team was able to solve the issue by strengthening the
underlying soil using Teretek® resin injection and
JOG Computer-Controlled Grouting, which effectively
re-levelled the building.
In Asia, Mainmark solutions and technologies are applied and adapted for
the varied local conditions. A large number of commercial projects have
been completed throughout the years, including several airport sites. At
Nagoya Airport in Japan, for example, Mainmark
re-levelled a drainage channel on one of the airport’s taxiways. Whilst
at Gimpo International Airport in South Korea, Mainmark
remediated a runway that was affected by subsidence. In Thailand, the
Mainmark team re-levelled and re-supported a factory
canteen floor that had suffered severe subsidence due to weak sub-base
soil and had become a dangerous trip hazard. The floor was successfully
remediated in seven days using resin injection
technology.
