Traylor SRG, LLC is a joint entity formed by Traylor Bros., Inc. and SRG Limited
to service the dam strengthening market throughout the US and Canada.
TRAYLOR SRG, LLC
Traylor SRG, LLC is a joint entity with Traylor Bros., Inc. (Traylor Bros) and SRG Limited (SRG) which was formed to service the dam strengthening market throughout the US and Canada. Traylor Bros and SRG both have a strong history and cultural alignment delivering complex civil infrastructure.
Traylor Bros has an outstanding track record and 70 years’ of history in North America Founded in 1946 and operating in transportation, water, environment, industrial and mining markets, Traylor Bros has a vision to be the most respected, preferred and consistently performing heavy-civil contractor in North America.
SRG is an Australian complex services company that solves the challenging and difficult problems that others can’t. Their vision is to make the complex simple. Since 1961, SRG has worked on many iconic stadiums, skyscrapers, bridges, dams, structures and mining projects both in Australia and internationally.
SRG are a global market leader in dam strengthening and have developed in-house the highest capacity permanent ground anchors in the world.
Traylor Bros has been working on marine projects located along the inland and coastal waterway system since the 1950’s, providing some of the nation’s largest port authorities and the maritime industry with the construction of deepwater container piers, wharf facilities, transit terminals, locks and dams. On the forefront of marine construction, Traylor Bros has partnered with the U.S. Army Corp. of Engineers on multiple flood control projects, where they have met or exceeded the aggressive - and crucial - deadlines.
DAM ANCHORING SPECIALISTS
SRG has a proud and extensive history as dam anchoring specialists, having completed projects throughout Australia, New Zealand, South Africa and Sudan. SRG’s proven success is a result of their technology and its continual development which enables them to provide a tailor made solution for every project, be it anchors of modest or extreme capacity.
Traylor SRG, LLC’s strong civil engineering and general contracting background allows us to fully understand project challenges and to develop cost effective, safe and highly productive solutions in cases of difficult access and complex anchoring requirements. No two dams are the same and our approach to each project is unique and focused on the delivery of outstanding outcomes for all stakeholders.
Traylor SRG, LLC are also equipped to provide a package of relevant disciplines in addition to anchors, such as drilling, access systems and monitoring.
BUILDING AMERICA SAFELY
Our number one goal is to “ensure every team member goes home safe every day.” That is why we are working so hard to create a culture of safety throughout the organization, where every team member “actively cares” for themselves and their co-workers each minute of every shift. Through our comprehensive improvement, we put our people first.
Anchoring is a sound and proven mechanism to provide restraint systems to dams and their auxiliary structures. Our technology provides reliable and compact permanent anchoring with ultimate single tendon forces currently exceeding 25,300kN, with further developments progressing to even higher load capacities.
Our achievements in permanent anchoring to dam structures are unsurpassed with an extensive portfolio of projects having installed hundreds of high capacity permanent anchors to many dam structures. We are innovators and industry leaders in the specialist field of high capacity anchors and have installed anchors over 142m in length.
The design and installation of anchoring systems requires a high level of diligence if premature failure is to be avoided. Equally vital is testing and monitoring of any anchor system both before and after it enters service.
Traylor SRG, LLC has the resources to test installed anchors of any size for compliance with ISO standards, even in the most difficult locations.
We have a dedicated team who continue to develop our technology to the next generation of anchors in order to expand our services.
Traylor SRG, LLC provides design and installation services for permanent ground anchors in dams including:
�� Dam wall stabilization
�� Retaining structures and point loads
�� Slope stability
�� Seismic resistance
�� Hydrostatic uplift due to increased storage
Our approach is to deliver the highest quality ground anchors, we do this by offering the following:
�� Premium corrosion protection to optimize life expectancy
�� Working with the client to create a solution for the project needs
�� Maintaining market leadership through continued research and development
�� Pledging excellence and exceptional client value from design through to the installation of anchors
�� Ensuring site works duration is kept to a minimum to deliver maximum value
World’s largest capacity permanent anchors, with a breaking load of over 25,389kN (2,589 tonnes) at Catagunya Dam in Tasmania, Australia.
