Non-conventional pipelaying saves

money – however, requirements

towards pipe material are higher!

Up to 50% cost for surface restoration

Strong growth in non-conventional installation techniques over the past 20 years

and today!

Point load

Sand bedding unnecessary thanks to modern materials• Use of excavated soil allows quicker and

more cost-effective installation.• In Rural regions modern techniques like ploughing and milling decrease the contracting time • Additional point loads are exert on the pipe during its live time by stones• Pipe system need to be stable against these point loads, so that these do not result in stress-induced cracking

Trench Installation without Sand bed

Special Quality Control of the slow crack properties guarantees the long lifetime of these pipes !
