Ground freezing technology builds in unshakeable stability

By Heather Hudson

Question: What ingenious construction technique has been around since the 1800s but is reserved for only the deepest, darkest jobs? 

Answer: Ground freezing.

Primarily used to provide ground support, groundwater control or structural underpinning during construction, the technology is mainly used for mine shafts. But its simple, virtually fail-proof design has made it a more popular option for civil projects in recent years.

“Ground freezing is still used a lot in mining, but we’re seeing it used for civil work like water tunnels,” said Joe Sopko, director of ground freezing at Moretrench, a nationally renowned geotechnical contractor based in Rockaway, N.J.

If you ask the folks at GeoRocFor Inc. how business is doing, they like to say they’re “getting through the toughest conditions.” That’s not because business is bad – quite the contrary: the Sherbrooke, Que.-based company is celebrating its 30th anniversary in 2015 as a leading manufacturer of drilling tools and an industry leader in overburden casing systems.

In the early 1980s, company founder and current president Roger Charland was working as a sales representative for an equipment distributor in Montreal, handling heavy drilling machinery, but not

By Kelly Gray

Strength in numbers is behind the growth of Toronto-based SPL Consultants Limited (SPL), a full-service, multidisciplinary ground engineering firm with offices in seven locations (Toronto, Vaughan, Cambridge, Ottawa, Markham, Barrie and Collingwood) across Ontario. The company’s wide-ranging specialties have allowed it to grow in five years from a group of five employees to a cohort that offers more than 250 highly experienced engineers, environmental scientists, hydrogeologists, technologists, biologists and support personnel. Since opening in 2009, SPL’s capabilities have had them working on ten of the top 100 jobs in the country as cited by Renew, and had industry watchdog Ernst & Young nominate them for Emerging Entrepreneur of the Year.

Behind their success is a willingness to be market sensitive.

“We have grown thanks to our quality of service, our ability to bring value into the engineering model and establish fair pricing,” said SPL Consultants principal, Fanyu Zhu, Ph.D., P.Eng., who adds that they are competitive without sacrificing quality. “We saw from the outset that there was a business opportunity that could be maximized if we could attract the people with the right skill sets and talent. I believe we have done just this.”

Giken America Corporation wants to standardize pile driving with its press-in piling methodology

By Ian Vaz, Giken America Corporation

The Giken America Corporation is a subsidiary of its parent company, Giken Ltd., with its headquarters located in Kochi, Japan. Giken was founded in 1978 from technology developed three years prior by the current president, Mr. Akio Kitamura, who collaborated with a local inventor known as the

“Thomas Edison” of the area. 

Giken’s press-in piling technology may have never been invented without the shutting down of a project in Kochi due to noise complaints led by a local sushi chef, which subsequently influenced Kitamura to develop this “outside the box” concept. With the contribution of over 300 employees globally, Giken’s minimal noise and vibration-free pile driving technology has developed into other various technologies over the company’s nearly 40-year history. The press-in piling market has also expanded recently throughout Asia, Europe and especially in North America and South America.
