Manhole Rehabilitation: Techs & Specs

This WEF webcast provides collection system engineers and owners with the tools they need to perform successful manhole rehabilitation projects. The first portion of the webcast will provide a background in manhole assessment and selection of appropriate rehabilitation technologies. The second portion of the webcast will focus on design, specifications, and quality.

Webinar: Developing a Deep Rock Grouting Design from Start to Finish
Each rock grouting project is unique – what worked on your last project may not be the recommended approach for another. The goal of this technical webinar presentation is to walk through a grout design process from start to finish for deep rock grouting applications – generally 50-ft. below ground surface or greater such as shafts, tunnels mines and deep dam curtains. It takes a deep dive into the details and pre-grouting data needed for a successful rock grouting project. This 75-minute learning event is outlined as followed: • Purpose of Grouting • Delivery Method – Specifications vs Contracts • Information Gathering – GDR and Data Collection • Details of Overall Design • Project Mock-Up: Shaft and Tunnel/TBM • Summary of a Real-World Project
Webinar: Geological Considerations and Parameters for Soil Permeation Grouting
Title: Geological Considerations and Parameters for Soil Permeation Grouting Original event date 6/11/2020. This presentation will discuss geologic considerations that affect the ability to grout in various soil types and which grout to use, and technical aspects such as particle size, fines content, drilling spacing and more which are essential for the success of a permeation grouting program. Presenters: Brad Crenshaw, PE, PG - Ground Engineering Contractors and Britt N. Babcock, PE - Avanti International

Geological and Hydrogeological Considerations for Achieving Water Cutoff in Rock: Which Grout to Use When and Why Original event date 5/14/2020. The goal of this technical webinar presentation is to understand why - from a geological or hydrogeological perspective - you typically use each type of grout to achieve water cutoff in rock - including Portland cement, microfine/ultrafine, sodium silicate, acrylate/acrylamide, polyurethane, and asphalt. Presenters: Brad Crenshaw, PE, PG - Ground Engineering Contractors; Britt N. Babcock, PE - Avanti International
Webinar: Buying Back Capacity: Rehab of Existing Sewer Systems to Maximize Cost ...
Title: Buying Back Capacity: Rehabilitation of Existing Sewer Systems to Maximize Cost Effectiveness of Public Utilities. Original event date 03.31.2020. About: The EPA estimates up to half of all volume at wastewater treatment plants nationwide is due to infiltration and inflow (I&I) rather than actual sewerage. Often, these organizations operate dangerously close to the maximum capacity of the collection system. This is due to lack of maintenance, creating a landscape where collection systems are unable to run economically and are forced to pass the cost on to the taxpayer. I&I has a tremendous impact on collection system capacity - especially during rain events when volumes can reach 5-6 times the average daily flow. On the surface, these issues are viewed as the result of population growth, deteriorating infrastructure, and significant rain events. However, nearly every issue can be traced back to the root cause - inflow and infiltration. There are several trenchless technology o...
Webinar: Injection Grouting for Industrial Applications: Cost-Effective Rehab of...
Title: Injection Grouting for Industrial Applications: Cost-Effective Rehabilitation for Concrete Structures. Original event date 04/09/2020. About: Concrete restoration is a highly specialized service that requires specialized tools and skills. In many cases, this requires the repair of cracks, cold joints, failing expansion joints, and other various defects in concrete. These defects may be actively leaking groundwater/rainwater and require pressure injection with urethane grouts. In other cases, defects may not exhibit leaks, but may present structural concerns therefore requiring injection with high modulus epoxy resins. These skills are valuable when approaching rehabilitation or repair projects for tanks, parking structures, elevator pits, storm vaults/catch basins, seawalls, and various other concrete structures. This webinar examines causes of cracks in concrete and the appropriate injection and epoxy grout applications to ensure long-term and cost-effective rehabilitation ...
Webinar: Clarity Point When to Grout, When to Line, When to Do Both and Why
Infiltration and Inflow (I&I) is a major factor in the degradation of our collection system. So what's the solution? CIPP Lining and Injection Grouting are proven methods, but very different answers and the best minds in the industry weigh-in on When to grout, When to line, and When to do both. And you'll learn WHY from multiple perspectives: owner, engineer, lining & grouting contractor, technology educator and technical director.
Webinar: Grouting for Greater Groundwater Control Before, During, After Tunnel C...
Subject Matter Experts share their wisdom so engineers, contractors, and property stake-holders can control groundwater before, during and after tunnel construction.
Webinar: Holistic Approach Solves Infiltration for Naperville, IL
Updated: Inflow & Infiltration are destroying our underground infrastructure. Learn directly from Superintendent Tony Conn of Naperville and John Manijak of National Power Rodding (Carlyon Corp) on both plan of action and execution to resolve infiltration. The issues are common for large and small communities. Results can be duplicated with Return on Investment measured in only a few years versus decades.
Webinar: Engineers Turn To Injection Grouting to Stop Sewer Infiltration
As wastewater utilities struggle to control inflow and infiltration in the sewer infrastructure, engineers are re-examining trenchless solutions to maximize infiltration reduction, minimize costs, and deliver long-term solutions. Injection grouting has a 50 year history and with ASTM standards, recent adoption of NASSCO specifications, and opportunities for Value-engineering, the future of injection grouting is a viable answer to excessive treatment flows, SSO's, and much longer lifecycle for underground assets. This webinar will examine causes of infiltration, injection chemicals, procedures, specifications, opportunities for value engineering and the role of the inspector to ensure long-term removal of infiltration from the collection system.
Webinar: Re-Living 50 Years of Municipal Sewer Grouting and WHAT'S NEXT
The past does not define; it prepares us for what's next. On the first ever World Trenchless Day (9/22/16), a cast of 10 very experienced industry experts came together for personal story-telling and relevant history, technology game-changers and views of visionaries shaping the practice of municipal grouting today. Not your typical webinar, this webcast is more of a documentary - entertaining & educational - with a rearview mirror glance back as well as forward looking statements with intent to bring a fresh new perspective to the original trenchless technology. The next 50 years of municipal grouting begins here.
