Sewer Leak Identification:  Electro Scan Compliments CCTV for Inspection

Public enemy #1 for managers of sanitary sewer collection systems is infiltration. Groundwater and soil fines enter into mainlines, manholes, laterals, and lateral connections through joints and defects. According to the EPA, nearly half the water entering treatment plant operations is clean groundwater - a direct result from lack of maintenance. CCTV has long been the most reliable technology for inspecting non-man entry underground assets, but experts agree, visual proof is not 100% conclusive. Enter: Electro Scan.

Chemical Grouting is for Life-Long Learners

Chris Hamilton - September 11, 2014 - Views 2716

Since becoming part of the Avanti family, I have met with dozens of grouting contractors and municipal crews with years of experience rehabbing underground structures. Most feel confident in their quality of work, and with balancing efficiency, effectiveness, and safety. As someone who served as an infrastructure restoration contractor for a decade, I know from personal experience how difficult it is to make procedure adjustments, modify processes, and implement subtle improvements.

CIPP Lining and Protective Coatings Need Infiltration-Free Environments

- September 04, 2014 - Views 2785

The original trenchless technology, chemical grout, is also complimentary to all other technologies. What do we mean be that? CIPP lining and protective coating are important technologies to sustaining our underground infrastructure. To realize maximum value of these structural repairs, active leaks must be stopped first. View this 3-minute, Cole Publishing interview with Don Rigby on how chemical grout stops leaks and provides an infiltration-free environment in manholes, mainlines, and laterals so structural repairs can realize their full life-expectancy.

Direct from Municipal Contractor: Manhole Rehab with AV-100 Outsmarts Water Intrusion

- August 28, 2014 - Views 3213

Customer call backs can be painful. And for one contracting company in Florida their call-backs were just that. It started seven years ago when they chose to align themselves with Brand X (who shall remain nameless) because of a lower price point. After high volumes of call-backs, they moved to Brand Y and then Brand Z, but continued to have unacceptable call-backs. Let’s be real – the manhole rehab business is tricky. In fact, the contractor had to call upon a competing resource to fix problems, and sure enough, this contractor was aligned with Brand A – A for Avanti.

Ultrafine Cement Grout Excels at Colorado School of Mines Field Day

It happens only once a year. Colorado School of Mines (Golden, CO) hosts a week long short-course on grouting. It’s attended by Who’s Who in the geotechnical grouting industry.

On the afternoon of June 19, 2013, the school hosted a Field Day and participants were able to view a live demonstration of the permeability of different grouts through Sand Column Testing. I’m pleased to announce, US Grout’s Ultrafine Cement excelled over other cement grouts by reaching the top of the sand column (60 inches) in just 80 seconds. No other cement grout came close.

Preserving the Underground Infrastructure at Miami-Dade

Communities large and small face a delicate balance of improving their underground sanitary sewer collection system and reducing flow to their treatment plant while being good stewards of the rate-payer and protecting quality of life. The intrusion of groundwater and soil files are sabotaging system efficiencies causing the plant to treat twice the volume, increasing sanitary sewer overflows, and polluting our clean water systems.

Preparation--Key Critical for Chemical Grout Repair Projects

Avanti Staff - February 25, 2013 - Views 3813

Planning for repair work is more than setting a date. Just like a good paint job is all about the preparation, so is chemical grouting. With work often in confined spaces, after hours, and sometimes requiring equipment shut down, it is vital to have everything ready to facilitate starting on time so you can finish as planned.
