Northeast Seawall Repair - Banner

Northeast Seawall Repair - BodyAs Alchemy-Spetec's Northeast Regional Geotech Lead, I am the point-person for contractors and property managers in this area of the country.  I also represent the NJ coastal, oceans, ports, and river engineers through the NJ COPRI, the Institute arm of The American Society of Civil Engineers. COPRI is responsible for evaluating data on ports, providing them with report cards on inefficiencies, and making recommendations for improvements. COPRI members also meet with leadership in Washington DC to give expert testimony on how funding should be appropriated for sustainability of US coastal areas, ports, and rivers.

I have developed feasible procedures for seawall remediation using polymer grouts, and have consulted with engineers and contractors to develop the standards for polymer seawall repairs. These standards are used throughout the US, and I regularly give presentations on them at engineering lectures and conferences.

In this blog post, I provide a simple introductory overview of seawall issues in the Northeastern United States.

Seawall Repair in New York, New Jersey, Pennsylvania, Massachusetts, Rhode Island, Connecticut, Delaware, Maryland and Virginia

Many Seawalls along the northeastern United States are in a state of disrepair, for a wide variety of reasons. Rising water levels, corrosion, seasonal freeze/thaw cycles, storms and extreme weather events all contribute to seawall deterioration over time. Properly built seawalls include a drainage system to handle the daily influx and outflow of water from rain, tides and waves. Over time, these drainage systems can sometimes become clogged. Seawalls without an effective built-in drainage system face a unique problem in that the water has no way to escape except to force its way down and out from underneath the base of the wall. When this occurs, sinkholes will appear alongside the wall.

Seawall Repair Options

Property owners facing seawall deterioration have a few options:

  • Do Nothing
    The problem with this option is obvious: longer you wait, the more expensive the eventual repair.

  • Replace the Seawall
    Rebuilding a seawall (or even a section of a seawall) can be messy, time consuming and expensive.

  • Repair with Cement Grout
    Cement grout seawall repair requires heavy equipment, large drill holes and the use of weighty cement grout which may sink over time.

  • Repair with Polymer Foam
    The polyurethane seawall repair process is accomplished with small mobile equipment, durable material that doesn’t sink, and small drill holes. This procedure makes less of a mess than replacing the seawall or repairing with cement grout.

Alchemy-Spetec structural foams are stronger than crystalline bedrock. Combined with proper drainage, polyurethane seawall repair can greatly extend the life of the structure.

Environmentally Safe

Alchemy-Spetec polyurethane seawall repair resin products have received the official NSF seal of approval for contact with drinking water (this also protects water-dwelling wildlife as well). This designation ensures compliance with the Safe Water Drinking Act (SDWA) and guarantees peace of mind for in-the-field stakeholders on construction projects of almost any scope and size.

Adam Tracy on How Long It Takes to Develop Field Competency for Leak Seal Grouting

Body - Adam Tracy on How Long It Takes to Develop Field Competency for Leak Seal GroutingThis article is an excerpt from Episode 4 of The Injection Connection, featuring Adam Tracy of A-1 Foundation Crack RepairThe Injection Connection is hosted by Jim Spiegel: Vice President of Alchemy-Spetec and Board Member at the International Concrete Repair Institute.  (If you'd rather listen, an audio version of this exchange is posted at the bottom of the article.)

Jim: Where do we find talent? That’s a big thing in our world especially being so niche of an application. How do you find talent? One of the things that we like to look at is, getting somebody with an engineering mind, such as yourself - engineering or architectural mind that just knows buildings and knows the X’s and O’s of the construction world and just get them on site, just to learn. We think that could be the one-two punch to really get good, competent people out there. You’re a perfect example of it. You come in with a very high level of understanding of the construction world and building in general and then couple that with some field training and you’re pretty lethal as far as your effectiveness in the field.

To that point, how long do you think it takes? Say somebody coming out of college: I have a bachelor’s in engineering, maybe I don’t want to work in an engineering firm, maybe I want to get into the sales side with the manufacturer building products. How long do you think it takes in field time with chemical grouting until you’re up and running and you really know the nuances of a lot of what happens out there?

Adam: That’s a tough question. I’ve used myself as a little bit of an example because while I’d been around it for a while because I had gone my own path for a period of time right out of school, it was kind of just there and didn’t really know much about it. Doing it every day, it was a good with my educational background being an engineer in the civil engineering space.  Knowing building and construction, it took me a good two, three months of every day (hands-on application to really understand the limitations, the successes, how it works, why it works, which product is going to be most successful, in which application) until I was comfortable being able to see the solution before I even put a drill to a wall. The fortunate thing is that I was able to rely on years of construction experience and being in these green builds whereas somebody who might be right out of school has never been on a site, has never thrown on the hardhat and the vest and walked around. So there’s a whole learning curve to that as well. But again, the field experience I think is critical in any industry. Especially as you get into more and more isolated niche industries, your opportunity to learn is few and far between on a study level. The field experience becomes your classroom.

When we bring people on, talking about finding good people, if we find somebody who has any experience in injection grouting, it’s a diamond, it’s a needle in a haystack so to speak. There’s a significant training curve on our end to bring talented people who have this construction experience to a level of being able to be proficient in the trade.

It’s a tough thing because everyone’s individual but the more time in the field, I think, is critical because, again, if you happened to be taught it in some educational level, it was a leap on the radar and it was quickly moved past as part of envelope education study whereas the actual time in the field really becomes your classroom, like I said.

Jim: Absolutely. It’s your point though or kind of to the point, two or three months was effectively your gut, visceral reaction there to time in the field. Compared to some other industries, that’s not all that long.

Adam: No but that was an everyday obligation.

Jim: Exactly. You take like a manufacturer rep for instance who might be on site once a month for a few hours to add that time up to be two months, constant trained would take years to become that well-versed.

Adam: In like anything. I’ve lived in that sales role as a manufacturer sales rep and while you may know the spec sheet of your product inside and out, that doesn’t tell you the whole story of the product that you’re going to use. It’s when it’s applied in the field whether it’s a pump or a truck or a crane or chemical grouting, it’s the performance in the real world beyond the spec sheet that tells you or completes a picture of your education on the product.

For those who are on the manufacturing side, the time in that field, actually doing the work I think is one of the most critical parts of it.

Jim: For sure. We liken it to a mechanic who can listen to an engine and give you a pretty good of what he’s up against. Very similar in the field, Charlie, who I mentioned, I think he’s been in the field services role for 15, 16 years as well and he can tell you what’s happening by the way the hose is jumping for instance on each stroke, and the sound of the stroke for instance. There’s a lot of that mechanic level field support that just isn’t that readily available in the chemical grouting world. We put Charlie in the field services director role because, and this is not intended to go into a sales pitch but just to your point that a lot of manufacturers are kind of shying away from the field support where you have to be out there seeing so many customers and making so many calls and it’s like a telemarketing solution sometimes for an industry that is so critical for accuracy in the field.

I agree with you completely. We actually tell our guys, you said you had experience on the sales side of it from manufacturer, and we tell all of our guys and girls – get in the field and spend time with the contractors. I still go out in the field. I was just on a job a couple of Fridays ago, we were doing polyacrylate gel injection. I was on the gun and I was saying to the technicians – you guys tell me, instruct me a little bit what you see out here because a couple of people who were out there had significant experience.

To your exact point, manufacturers can read spec sheets and tell you little nuances of performance from TDS but until you know what the gun feels like, the guys in the field are still probably head and shoulders above you.

Adam: Yeah, for sure. And it’s always tough to be in that role where you’re supposed to be the expert and asking for help. I’ve been in those situations, it’s always uncomfortable as being on the manufacturer side to say, "okay, what would you guys do here?"...you know, being the guy with 30 years of experience.

Adam Tracy on What Can Be Improved in the Chemical Grouting Industry

Posted by Kreg Thornley on Mar 3, 2020 3:20:58 PM

Banner - Adam Tracy on What Can Be Improved in the Chemical Grouting Industry

Body - Adam Tracy on What Can Be Improved in the Chemical Grouting IndustryThis article is an excerpt from Episode 4 of The Injection Connection, featuring Adam Tracy of A-1 Foundation Crack RepairThe Injection Connection is hosted by Jim Spiegel: Vice President of Alchemy-Spetec and Board Member at the International Concrete Repair Institute.  (If you'd rather listen, an audio version of this exchange is posted at the bottom of the article.)

Jim: In a more general sense with the chemical grouting industry, what do you think, and I may be putting you on the spot here a little bit, but what do you think is lacking or what could be improved in the industry? Do you have opinions on that? Maybe from a product standpoint, maybe from a service standpoint, from the manufacturer’s side? Do you have any thoughts on that?

Adam: I’ve had a pretty unique entry into this industry because I’m from totally outside of the industry. Even though this is a family business, I actually spent the first ten plus years of my career as a manufacturer rep in the fire protection space. So, I’m coming at this industry as a very different set of eyes. I’m actually an engineer in civil engineering and I would definitely say that it’s a niche industry in a lot of ways, which prevents its usage I think because I don’t think it’s well taught on an educational level and I don’t think the awareness is very high amongst a lot of engineering firms as well. 

It’s a process that is unique in a lot of ways but it’s not revolutionary. I think while it’s one tool in the tool belt as we discussed, I think having that in an engineer’s hands is very important because a lot of times solutions that are tried more often or may have a higher success rate on the positive side are just cost prohibitive. And the building is not set up to be able to do that kind of stuff post construction and where chemical grouting is really just the best, most cost-effective, high result solution for that particular application.

I would definitely say that on a commercial level the grouting process needs to have a little bit higher expansion in educational areas to make sure that kids coming out of schools and going in for their PEs and trying to get their feet under them and provide solutions to their clients know that this is a proper solution that is tried and true and is very successful.

In my world, where it’s a lot of residential, that’s half of what my job is on a day to day conversation with a customer is explaining what we’re doing because it’s a lot of black magic in their eyes because it’s something totally different. They were looking for the black spray in the can that you used to spray in the bottom of your screen door boat there, off the shelf as a solution and they‘re trying to figure out why it didn’t work. And really, we’re trying to just educate them a little bit as well.

We’ve had projects in the past where they’ve spent a tremendous amount of time on the specifications and the procedures on how to address an issue. We had a project at a wastewater treatment plant where it’s 24-inch walls, thick walls with rebar everywhere, and they were tall. And they’re just trying, there’s not a lot of experience, there wasn’t a lot of manufacturer help in terms of how to really identify the process to do this successfully. So, when we get in there and we look at the specifications, it’s hobbled together by somebody who’s never seen this process in the real world. It was essentially set up for failure in a lot of ways because the process was wrong for this particular application, and trying to go through change orders of the process was a very difficult situation - just because we knew as a contractor doing it for as long as we have that the amount of time and effort that they were going to be focused on their particular process was going to be set up incorrectly and set up for failure mostly because, again, they had a set of people on this thing who have read about it and were very unaware of the infield techniques that are required to be successful in it, and really just tried to be by the book on it without any sort of experience.

I think that in the industry, there would be a huge benefit across the board in my eyes to really start at the educational level, civil engineering programs, construction management programs, to really focus on that. I think manufacturers have some responsibility as well as contractors to give a two-pronged approach so that people are educated both on the technology itself and the actual application and how it gets done.

Jim: I couldn’t agree more.

Deep Soil Stabilization with Polyurethane - A Case Study

Posted by Andy Powell on Feb 28, 2020 3:08:30 PM

1.Banner-Deep-Soil-Stabilization

2.Body-Deep-Soil-StabilizationI'd like to share a case study from a recent job that I consulted on with one of our contractor customers.

A two-story residential house in North Carolina was built on poorly compacted fill dirt. After about 20 years, it began showing evidence of settling. Interior cracks appeared in the sheetrock and some of the floors were no longer level (indicating that the footings were slowly sinking). These symptoms of unstable soil were caused by about 1 inch of settling. The engineer on the project determined that the problem was not severe enough to require helical piers. The contractor was called in to stop the sinking and reinforce the soil via deep soil polyurethane injection.

Powerful Polymer

Among the most dependable products for geotech applications, AP Lift 440 structural foam provides an exceptional DOT grade solution for these types of situations. This 4 lb. density, high-strength, hydro-insensitive structural polyurethane foam is perfect for densifying soil and stabilizing foundations (as well as lifting).

Painless Procedure

I worked with the contractor to draw up a plan, indicating exactly where the injection points would be located. The engineer reviewed the plan for feasibility. The contractor installed 18 injection tubes to a depth of 7 feet. 50 lbs of foam were administered through each tube, split between two different depths: 7 feet and 3.5 feet below grade. First, they injected from outside the house, installing foam beneath the exterior footings. Next, they injected from inside the house, installing foam beneath the load bearing interior walls. Spacing between injection points was approximately 5 feet.

Rapid Result

The deep soil stabilization process densified the soil and stopped the settlement. In addition, the contractors achieved a half inch lift from the exterior injections and another half inch lift from the interior injection sequence. The customer was extremely happy with the results. The engineer was impressed as well and said he would recommend this procedure in similar future scenarios.

Polyurethane Seawall Repair Explained

Posted by Michael Binyaminov on Feb 18, 2020 2:43:14 PM

Polyurethane Seawall Repair Explained

Polyurethane Seawall Repair ExplainedWhy Do Seawalls Deteriorate?

The Elements
Salt corrosion, tidal action, currents, boat wakes, storm surges and heavy rain events all deliver a constant beating on the seawall. Every time it rains, or the irrigation system runs, and every time the tide goes out; all of the groundwater above the waterline has to vent or equalize. Tremendous pressures can build up if that water is trapped and cannot make its way into the sea or the storm water system.

Structural Aging
Correct construction of a seawall includes a drainage system to handle the bulk of the water that comes from rain in addition to check valves, weep holes, or seams to handle the daily influx and outflow from tide and wave action. Over time the materials degrade or can be disturbed by settling. The result is a loss of soil and the inevitable sinkholes and / or low spots that will occur along the wall. Other times, the weep holes and vents become clogged and the water has no way to escape except to force its way down and out from underneath the base of the wall. When this occurs there will again be sinkholes and sometimes wall failure.

Why Use Polyurethane for Seawall Repair?

Non-Intrusive Application
Polyurethane can be injected through pipes directly into voids and loose sandy soil using small portable equipment.

Proven Solution
Seawall repair resins are used extensively seal cracks, voids and defects as well as for filling voids and stabilizing the soil.

Creates an Impermeable Mass
Polyurethane seals leaks along the wall, fills the voids that have occurred, and mixes with the soil to form a solid, impermeable mass.

What Are the Results of Polyurethane Seawall Repair?

Long Lasting Solution
Alchemy-Spetec seawall repair resins cure to a strength greater than crystalline bedrock. Combined with proper drainage, this method can greatly extend the life of your seawall.

Water Tight Seawall
The resin reacts with water or moisture in the soil and expands to fill voids while it permeates sandy soil to form a solid, strong, watertight mass.

Environmentally Safe
Alchemy-Spetec offers seawall repair resins that are approved for contact with drinking water (certified to NSF 61-5). That means they can be used anywhere without having an adverse effect on water quality.

Quantifying Chemical Grouting Effectiveness with The QP Factor

Posted by Jim Spiegel on Feb 13, 2020 3:24:16 PM

Quantifying Chemical Grouting Effectiveness

Quantifying Chemical Grouting EffectivenessThis blog post features Episode 2 of Alchemy-Spetec's The Injection Connection podcast.

This is a presentation given to an engineering firm regarding the new patented leak seal QA/QC system The QP Factor: the first patented method to quantify leak seal grouting and leak seal effectiveness.

As mentioned in our previous post on this system...

The method of testing requires additional drill holes to be placed at pre-determined locations along the crack, joint, or substrate being sealed. Prior to injection of chemical grouts such as Spetec PUR F400, Spetec PUR HighFoamer, or Spetec PUR GT500, the test hole is connected to a digital touch-screen device that is calibrated to provide water pressure, flow, and flow/pressure information that is extractable in excel format from a convenient USB port.  Following initial testing, the test port is then plugged during chemical grouting operations to avoid false-positive results after injection. 

The presentation was first unveiled at the International Concrete Repair Institute, National Convention in Jacksonville, Florida, in 2019. Due to the context, there may be some points that seem a little abstract to the average viewer. If you have questions or need more details, please call Alchemy-Spetec at 404-618-0438.
