WEBINAR: Acrylamide Grout Saves the Day for TBM in Portland, Oregon

The design of the Balch Tunnel - located in Portland, OR - called for the use of a Tunnel Boring Machine (TBM) in the gravel substrate of the area. As the TBM progressed, soil stabilization was required to keep the TBM in alignment. To stabilize the gravel in front of the TBM and after multiple product considerations, AV-100 Chemical Grout (Acrylamide) was used, allowing the project to continue as planned. This 75-minute webinar will discuss an overview of the different types of injection grouts, where they are used, and in what applications, and then dives deep into the design and details of the Balch Tunnel Grouting Project.

WEBINAR: Buying Back Capacity: Rehab of Existing Sewer Systems to Maximize Cost Effectiveness (2020)

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 options available to the collection community. However, the only technology that is designed specifically to eliminate infiltration is injection grouting.

This webinar will examine causes of infiltration and the appropriate injection grout applications to ensure long-term removal of infiltration from the collection system that will buy back your capacity.

WEBINAR: Choose Wisely: Cement Grouts, Chemical Grouts, or Both (2013)

Not all grouts are created equal. Each type is engineered and produced with unique properties providing specific attributes for both new construction and rehabilitation projects. Which one or both?

WEBINAR: Developing a Deep Rock Grouting Design from Start to Finish (2020)

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. 

WEBINAR: Engineer & Contractor Agree: Chemical Grout Stops Infiltration in Large Diameter Pipe

With century old infrastructure, Granite City, IL embraces floods every spring by virtue of its location in the Great American Bottoms. The stress on the system is obvious as infiltration is blamed for sinkholes and foundation failures.

WEBINAR: Engineer, Owner, Contractor - Know Your Role to Optimize Manhole Rehabilitation (2016)

Every manhole has a unique personality. Traits include defects, decay, construction materials, and age. Manhole structures battle environmental influences—fluctuating groundwater table, hydrostatic pressures, PH factors, and H2S corrosion. To combat these conditions, control I&I, and restore integrity, the engineer, owner and contractor have defined roles and responsibilities. Efficiency and effectiveness matter. Know your role. Know the issues. Learn the whys. And plan manhole and wet well rehab for the long run.

This one-hour, online-learning event promises clarity from multiple perspectives: engineering, contracting and technology experts.

WEBINAR: Geological and Hydrogeological Considerations for Achieving Water Cutoff in Rock (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.

WEBINAR: Geological Considerations and Parameters for Soil Permeation Grouting (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.

WEBINAR: Holistic Approach Solves Infiltration for Naperville, IL (2015)

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: Injection Grouting for Industrial Applications: Cost-Effective Rehab of Concrete Structures (2020)

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 to extend the life of your concrete structures.

WEBINAR: Interactive Conversation on Controlling Groundwater in Mines, Tunnels, & Subways (2014)

A collaborative presentation with speakers from ECO Grouting Specialists, US Grouting Specialists, US Grout, and Avanti International.

WEBINAR: Pipe Soil Structure: The Progressive Loss of Soil Caused by Relentless Infiltration

Infiltration: an enemy to the collection system and the rate payer. If not addressed, infiltration can ruin the collection system. As infiltration enters a pipe or manhole through faulty joints or defects, it also brings with it soils fines from outside the pipe. The progressive breakdown of the pipe soil structure is the eventual cause for system failure causing pipe disintegration, reduced capacity, costly repairs, hazardous sinkholes and potential injury or danger to the community.
Where do you start in the fight against infiltration? This webinar will layout the consequences of infiltration and the value benefit to eliminate is starting with identifying the problem, discovering a solution, and implementing the right trenchless method.

WEBINAR: Preserving the Underground Infrastructure at Miami-Dade (2013)

Communities large and small battle infiltration. Miami-Dade is the 6th largest water and sewer district in the U.S. and reducing flow 128 MGD to their treatment operations. Chemical grout is the low-cost, high-reward strategy for reducing I&I at Miami-Dade with defensible justification of saving $2.50 in cost for every dollar invested in their maintenance program. Learn directly from the following experts: Rod Lovett, Chief of Wastewater Collection and Transmission Line Division at Miami-Dade; Stuart Rome, International Development for Cues, Inc.; and Daniel Magill, President of Avanti.
