Tech Tips
Touring NASSCO’s new sewergrouting.com website
By NASSCO Board Member & ICGC Committee Chair John Manijak, Hoerr Construction
Information about what is believed to be the oldest trenchless technology has just gotten easier to find. ICGC – NASSCO’s Infiltration Control Grouting Committee –has just completed a full revision of its website found at SewerGrouting.com.
NASSCO’s vision is “To increase the awareness of aging underground infrastructure and to provide viable solutions through education, technical
resources and industry advocacy.” Creating a viable source for information that is easily available was just one of the many reasons for the update of SewerGrouting.com. The website is linked to NASSCO.org to make it quick and easy for trenchless professionals to find valuable information and guidance on the topic of infiltration control / grouting.
In line with the NASSCO vision, there is excellent information found on the website that can help educate, provide technical resources, and advocate for grouting as a proven trenchless technology. At the top of the home page is a six-minute video on chemical grouting. First released in 2021, this introductory video was produced by members of ICGC and is filled with important information on grouting processes, I&I control, and historical statements.
The website contains eight distinct segments, each one specifically designed to provide a collection of information on their respective topics:
Applications – Injection grouting is often used to stop water infiltration and provide structure stabilization. Each of the following website pages provide a detailed description of the processes used along with a short video of those methods used to seal.
- Mainline – Means and methods used to seal mainline pipes.
- Lateral – Means and methods used to seal lateral pipes and the mainline/lateral
intersection. - Manhole – Means and methods used to seal access structures.
Safety – Released in 2022, The Unified Safe Operating Practices Program (USOPP) and accompanying Grout Safety Exam is aimed at the protection of not just the industry’s field workers but also warehouse personnel, engineers, transporters, and inspectors. In line with NASSCO’s overall safety focus, the safety section of SewerGrouting.com provides additional information for everyone that is involved with grouting operations.
- Dos and Don'ts – A great source for toolbox talks for grouting job sites.
- Grouting Safety Exam – Description of the USOPP program and a link to the course within NASSCO’s training source website. Successful completion of the Grouting Safety Exam earns students 3 PDH or .3 CEU credits.
