Trenchless and Traditional Rehabilitation Design Services
From Duke’s Experienced Engineering Team
With the ever-increasing levels of urban and suburban development, and the constantly expanding presence of underground utilities, effective approaches for non-invasive water and sewer system pipeline repairs have never been more crucial. Duke’s specializes in the design and planning of trenchless rehabilitation projects, which are becoming more and more cost effective due to requiring fewer permits, less planning, and reduced disruption.
By eliminating the need to excavate a damaged pipe, trenchless rehabilitation is the ideal method for repairing underground pipes in a wide array of locations where other infrastructure may make repairs difficult. Depending upon the specific pipe-repair project requirements, Duke’s can develop a plan using a variety of trenchless rehabilitation techniques.
Duke’s Trenchless and Traditional Rehabilitation Design Capabilities Include:
Pipe Liners: Also known as “cured-in-place piping,” or CIPP, this technique makes use of a flexible liner, impregnated with resin, which is inserted into a damaged pipe and cured to form a pipe within a pipe. This is a very widely-used technique for repairing damaged pipes with few bends or corners without the need to excavate the pipe.
Pipe Bursting: Using an “expander head,” pipe bursting involves the linear destruction of an existing underground pipe while pulling a new pipe in to fill the underground space among the fragments of the previous pipe. This technique is also used to install a larger-diameter pipe in place of an existing pipe without the need to dig the pipe up.
Sliplining: Sliplining is a very straightforward form of trenchless rehabilitation that involves simply inserting a smaller new pipe into a larger existing pipe. Drawbacks of sliplining include reducing the overall capacity of the existing line.
Spray-Coat Lining: Using robotic technology and remote CCTV cameras, some damaged pipes can be repaired by spraying a fast-setting sealant to cover cracks in existing pipes. This technique will only be effective in minimally-damaged pipes.
Overseeing Project Bidding and Field Work
To Promote Successful Trenchless and Traditional Rehabilitation Projects
Beyond simply designing effective trenchless rehabilitation projects, Duke’s helps ensure the most successful outcome possible by overseeing the project bidding, selecting contractors, and administrating the work in the field. Our engineers and supervisors specialize in fostering the best results possible using their extensive experience and know-how.
