Rehab Technology



In 2019, Avanti is offering for the first time, a certification program for grouting technicians. The objective is to validate knowledge and competence in solution grouts and application of best practices to seal the collection system from infiltration of groundwater, exfiltration of sewerage, and stabilization of the sewer trench from further erosion of supporting soils.

Conducted at the company’s Webster- Texas, headquarters, the two-day “Advanced Insitu Grout Chemistry & Best Practices” course, or “Level 300,” provides grout technicians with both classroom and hands-on lab experiences to better equip decision-making in response to variable conditions, such as soil types, temperature extremes and presence of groundwater.

The first day focuses on the process of injecting a two-component acrylamide grout through pipe joints and defects into supporting soils to create an impermeable seal, which stabilizes the sewer trench. With controllable gel-strengths, set-times and additives that change outcomes, specialized knowledge and skills are necessary.

Day two focuses on best practices and is instructed by a different guest expert quarterly. The first one will be John Manijak, services manager-Midwest for Michels Corporation.

With 20 years of injection grouting experience, he has performed as project manager, business development manager and is now mentor to dozens of people reporting to him at Michels. Recognized with the Golden Manhole Award in 2015, Manijak is an active member of CSWEA, APWA, NASSCO and ICGA, and is a popular speaker and author on I&I control using injection grouting.

Prerequisites for attending Level 300, include Level 100, Fundamentals of Municipal Grouting, and Level 200, Municipal Sewer Grout School, focusing on the mechanics of grouting. Avanti also requires certification on Safe Operating Practices Program.

Upon successful completion of the prerequisite courses and the Level 300 written test, candidates will receive certification validating their knowledge and achievement.
