Ultimate strength, ultimate solution!

When EJOT became custodian to the LIEBIG anchoring range, the Group’s manufacturing portfolio expanded with the physical size of LIEBIG anchors adding a new dimension – notably, the ULTRAPLUS undercut anchor.

The LIEBIG ULTRAPLUS design offers the highest tensile and shear performance of any other undercut anchor on the market, from 320KN tensile load and beyond, so it is easy to appreciate why structural engineers all around the world respect this unique anchoring technology for the most critical applications.

So… how Big is BIG?

We refer to the diameter first – ranging from 10mm to 36mm (M10 to M36). Its modular design means that lengths are often bespoke to suit a particular application – and there are many M36 variants in place that measure up to 1.5m.

 

ULTRAPLUS in action

With an ETA for cracked and uncracked concrete that includes seismic and load case fire, think of anywhere where structural and human safety is paramount; from a theme park ride to a nuclear power plant installation.

Paul Papworth is EJOT UK’s LIEBIG specialist. Recent projects that he has been engaged with include installations at a hydro power, nuclear waste and waste treatment plants, plus the installation of a nuclear-powered submarine testing bed. Paul explained:

“For the hydro power plant, M36 diameter stainless steel ULTRAPLUS anchors were used to hold down a tunnel liner in the main water inlet tunnel. Ultra-high performance anchors were needed here due to a significantly high rip force that was created by the water passing through a 90 degree inlet. These massive forces had previously ripped up the 25mm steel liner.”

“The nuclear waste plant utilised M24 x 1.2m long ULTRAPLUS. Significantly high load and safety factors, including risk of failure, were the driving factors behind specification. The length of anchor chosen meant that sub-level utilities could be avoided. Anchor performance was also enhanced, providing extra strength.”

“M36 diameter zinc plated ULTRAPLUS anchors were installed at a chimney stack on the waste treatment plant in the north of England. High loadings were present in the structure, so an immediate take up of load was required – which is one of the ULTRAPLUS anchor’s unique application benefits.”

LIEBIG Anchoring Technology set to resurface following acquisition

Most Civil and Structural Engineers with a respectable ‘mileage on the clock’ will be familiar with the LIEBIG brand and the high quality of anchoring technology associated with it. Some have expressed frustration over the brands inaccessibility in recent years, largely where to source products or acquire performance data.

 

The good news is that LIEBIG is alive and well and in safe hands having recently been acquired by the global fastenings manufacturer EJOT, as part of the acquisition of Finnish company, SORMAT. Add to the mix that SORMAT itself acquired LIEBIG from Simpson Strong-Tie International Inc. back in 2012, and it’s easy to spot the confusion – something management at EJOT’s UK manufacturing centre near Leeds, are keen to put right.

 

Robert Hardstaff is EJOT’s managing director in the UK:

“EJOT manufactures high performance fasteners for the modern building envelope. Our pedigree in terms of technical innovation is second to none and therefore, a perfect fit for LIEBIG. By combining our global knowledgebase with LIEBIG’s specialist teams we will ensure that the product range is easily accessible, continues to be performance-driven, and supported by responsive technical guidance”.

 

Paul Papworth has recently joined the EJOT team, bringing a wealth of knowledge born from a career spanning more than 30 years in construction fixings and anchoring. Paul worked for a leading anchor manufacturer in the UK and Asia region for most of that time. He outlined his working knowledge of the Liebig product range:

 

“We will focus our attention on the major LIEBIG products and variants. That’s the Ultra-plus and Super-plus undercut anchors, and the high-performance LIEBIG Anchor and Safety Bolt. These are hallmarked classics and we want engineers to know where they can come to for the products and for guidance. They also need to be aware that the modular nature of the Liebig range makes all of these anchors easily adaptable, which means they can get bespoke lengths and assemblies quickly, efficiently and of course, cost-effectively.”

 

Paul has thoroughly briefed LIEBIG’s product USP’s to his new colleagues. Gary Robson is EJOT’s sales engineer in the north of England and in turn, has been working closely with Paul to familiarise him with EJOT’s own concrete fixings range.

 

“Customers looking to source LIEBIG products can now access technical information. We recognise that LIEBIG anchors are specification driven. The modular flexibility of LIEBIG products simply means that with the correct technical guidance, purchase and supply is just as fast. The ethos of EJOT’s business model is one of technical support, so we would encourage any customer in need of further assistance to make contact”.

 

The EJOT Group employs over 3400 personnel worldwide. In the UK, EJOT’s testing and development facility, Applitec, is pivotal in providing support to its national team of sales engineers. EJOT UK is one of only six manufacturers to gain full membership status with the Construction Fixings Association.
