Third-Party D-Load Testing of Spray-Applied Liners

Join us for this live event – a free, 1-hour educational webinar. The Trenchless Technology Webinar will be focused on the Third-Party testing that was performed utilizing a D-Load testing station in 2018.  The testing performed consisted of 48” RCP.  Two pieces were D-Load tested without any polymer coating.  The pressure needed to create a .01” wide crack running down the lateral side of the pipe was recorded.  This cracking simulates a “failure” in the tested pipe.  Six additional 48” RCP’s were precracked to the same .01” width.  These pipes were then lined with a structural polyurethane liner with 250 mils, 500 mil and 1000 mils being applied in two 48” RCP’s at the respective thicknesses.

After lining the six pipes, they were all tested using the same methodology in the D-Load testing station.  The lined pipes were loaded until Ultimate Failure occurred.  This Webinar goes through the testing and compares the end results with the unlined RCP with the 250, 500 and 1000 mil lined pipes.

Learn about ultra-high-build epoxy liners and how they are an upgrade to traditional epoxy coatings


Learn more about the differences between traditional coatings and what an applied ultra-high-build epoxy lining solution offers. Join Epoxytec to learn exactly what an applied ultra-high-build epoxy lining system is, when to choose them, and what other factors they can bridge compared to traditional coatings.

Today’s rehab and lining solutions offer end-users and asset owners a vast menu of technologies to choose from, including polymer coatings, such as epoxy coatings. The current range of coatings has also evolved. Traditional epoxy “paint” coatings that were designed some decades ago for simple immersion-grade protection against corrosion have been tuned up. Now, innovative manufacturers of coatings are offering completely overhauled applied polymer coating and lining products, bringing them into a category of their own – a category of applied ultra-high-build polymer lining.

An Integrated Approach to HDD Design and Optimized Construction

Integrated Trenchless Engineering Inc,Laney Group, Inc.

The installation of horizontal directional drill (HDD) crossings has become one of the most common trenchless methods for installing pipelines in the oil and gas, municipal, power transmission, and wind generation industries.  Engineers are often asked to design an HDD installation for a project, but most have little knowledge of how to properly design an HDD that is constructible and reduces the risk of hydraulic fracture and drilling fluid surface release.

As engineers and constructors of HDD installations, we see many HDD designs that are not constructible as originally designed.  As a result, we often redesign many of the HDD installations we construct. Based on our experience, we have developed an integrated approach to design our HDD installations.  This workshop will go beyond the basics of HDD design and share ideas and concepts that will help engineers better understand the need for an integrated approach to the design process to optimize construction.

Direct Pipe® Trenchless Method – Overview of Feasibility, Engineering, and Construction with Case Study Examples For Practical Application


Following its first use in Germany in 2007, Direct Pipe® (DP) has rapidly developed into a unique and critical option for steel pipeline installations. DP draws on conventional, steerable microtunneling technology to excavate the ground in the proposed pipe heading. The Pipe Thruster machine pushes or jacks the pipe through the ground utilizing a circular, hydraulically-actuated clamp that grips the outside of the pipe and thrusts it along its heading.

Using case history examples, principal engineer, Jon Robison, PE, from GeoEngineers will also present the DP method and technology, share its advantages, and discuss potential applications and risks from a trenchless and geotechnical engineering perspective. Robison will introduce the critical concepts of steel design engineering, including stress analyses, and buckling which are especially important for pipe that will be subsequently subjected to high operating pressures. Finally, he will discuss the DP construction process, documentation, and quality assurance.

Delivering Reliability, Resiliency and Sustainability

Logistec Sanexen

In the context of the COVID-19 pandemic, water infrastructure resiliency is more important than ever. On June 2, Cornell University’s School of Civil and Environmental Engineering issued its final Report “Performance Evaluation of Aqua-Pipe under Earthquake-Induced Ground Deformation” which details technical findings confirming that SANEXEN’s next-generation of water technology is proven to withstand severe earthquake conditions and natural disasters.

Experts Martin Bureau, VP Innovation at SANEXEN and Benoit Côté, President of SANEXEN Water will share how the resiliency achieved by the Aqua-Pipe technology has exceeded all known standards and outperformed every other solution on the planet and what it means for cities and municipalities across North America.

The webinar will outline how the next-generation of water technology delivers the highest degree of resiliency, reliability as well as being sustainable for the environment and the economy.

Manhole Rehabilitation Pays Dividends for Decades


Beyond I&I reduction, the cause for Manhole Rehabilitation is clear: restore structural integrity, provide corrosion protection, and reduce flow to the WWTP for increased capacity and decreased cost. Understand the engineer’s role in assessment, specification, and onsite inspection. Know the contractor’s role—execution is everything. Hear testimony of municipal stakeholders on ROI and long-term performance. If you’re part of a team that cares about the collection system, Dividends for Decades is 60 minutes well invested. Learn well from a team of experts at Commonwealth Engineers, Culy Contracting, and Madewell Products.

What is Measured, Improves: Maximizing Infiltration Reduction and Rehabilitation Effectiveness


Locating and reducing inflow/infiltration (I/I) is a common challenge facing wastewater collection systems, yet effective identification of infiltration has been nearly impossible using Closed-Circuit Television (CCTV), Smoke Testing, and Dye Flood Testing results.

Too often Agencies only learn that I/I flow reduction goals were missed after multi-year flow monitoring results; citing ineffective prioritization, poor contractor performance, and inability to reliability certify repairs as watertight, especially after service restoration.

Today, Agencies are adopting machine-intelligent Focused Electrode Leak Location (FELL), in accordance with ASTM F2550, to identify I/I and test rehabilitation as watertight. Unbiased and automated inspection results are replacing legacy ambiguous and subjective testing to (1) prioritize pipes with the highest infiltration, (2) test the watertightness of repairs & that rehabilitation meets contract requirements, and (3) compare before and after leakage results to get ‘same day’ estimated percent reductions in flow.
