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

Don Rigby - August 28, 2014 - Views 2884

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.

Safety, not just some of the time!

Avanti Staff - April 15, 2013 - Views 3124

Anyone who has spent time in the military understands and accepts you may have to give your life at some point. No one should be ready or need to give their life rehabilitating a sewer. Sadly and unintentionally, this is what happened here.

"Briceno…had removed his harness to reach a confined space and was carried away by the rushing water, according to police officials at the scene. The other worker was strapped into his harness and was pulled to safety,” the officials said.

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 3496

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.

How to Choose a Grout for Sealing Mainlines and Laterals

- February 25, 2013 - Views 3155

Below are some questions to consider when choosing a grout for sealing mainlines and laterals--before, after, or independent of lining:

  1. Cost: Cost should only be one factor. What is more important is that you are using the appropriate product for the job and the grout is applied correctly--in accordance with the 2012 NASSCO recommendation is a good start.
  2. Cost vs. Cure Time: Grouts have different cure times. Be sure to check tech data sheets to determine how much control over cure time you will have in the field. Better yet, you can do a more thorough investigation by performing your own tests. The more catalyst you need to reach the desired goal, the more money you'll spend on product.

Joint Failure Not Always Obvious--Test Every Joint

- February 25, 2013 - Views 2922

I visited a job site a few weeks ago and talked with the grouting operator. I found three things very cool:

  1. It was nice to visit a grout truck that was kept clean and orderly. This was a municipality that only has one crew responsible for each grout truck, so they treat it like their own.
  2. They air tested every joint. There is no point in grouting only the visible leaking joints and ignoring the ones that are not noticeable. The joints must pass an air test or should otherwise be grouted. If not, once you grout the leaking joints, the groundwater simply migrates to the next joint and enters there.
