Stop Erosion Through Your Seawall with Polyurethane

A seawall is like a living, breathing thing: especially in the way that it is designed to function. But like all living breathing things, seawalls have a finite lifespan. For many of them, it's a mere 20 – 30 years. Depending on where you live, replacing a seawall can cost anywhere from $150 to $500 per foot. That's enough for some homeowners to choose to move instead of rebuilding their seawalls. Today however, signs of seawall distress can be solved before they get too bad through the application of polyurethane grouts to seal leaks, fill voids, and stabilize the surrounding soils.

An In-Depth Look at Polyurethane Seawall Repair

In this blog post we’ll look at an innovative way to repair seawalls instead of replacing them by stopping high flow leaks, filling the voids behind concrete structures and binding loose soil with polyurethane foam. As tidal flows rise and fall, water pushes its way in through cracks, joints, and defects in seawalls. The water pushes in on incoming tides and flows out on outgoing tides. As the water flows out, it carries sand and soil with it which causes undermining of the structure. Click here to read more...

Residential Seawall Repair

If you love the ocean, then living near the water can be an ideal situation most of the time. You can enjoy scenic views of the sea, easy access to the water, and gentle ocean breezes as you sit out on your deck. But one challenge many oceanfront home owners eventually find themselves facing is leaking seawalls. You depend on seawalls to keep water on the outside and the the soil that supports your property on the inside. The seawall protecting your property is vulnerable to many degrading factors.

Signs a Seawall is in Need of Repair

Salt corrosion, tidal action, currents, boat wakes, storm surges and sometimes hurricanes all deliver a constant beating on the seawall. Contrary to popular opinion, many of the forces also come from the side of the wall facing the land. Did you realize that rainfall/storm events create more hydrostatic pressure than rising and falling tides? Every time it rains or the irrigation system runs, and every time the tide goes out; all of the groundwater above the waterline needs a place to vent or equalize. Massive pressure can build up if that water is trapped, making it impossible for it to drain into the sea or storm water system. That is a recipe for disaster which can easily be avoided with proper surveillance. Let's take a look at some of the external signs a seawall is in need of repair. Click here to read more...

Whether it’s your first time or you’re a seasoned veteran, this guide can serve as a simple checklist to keep your equipment and 16-20 foot trailer safe as you travel to your next project.

Give Yourself Plenty of Room to Stop and Turn

When towing a trailer, the distance required to stop is more than most people realize. The amount of space between you and the vehicle in front of you must be doubled if not more compared to driving without a trailer. The same is true with turns. Allow more space than you think you may need between you and any curbs or other vehicles. And don't jackknife the trailer (a turn so sharp that it touches your bumper) as this can cause damage.

Keep Your Trailer Grounded

Winds, downhill grades, and momentum can all lead to trailer swaying. We recommend utilizing a hitch stabilization device to negate some of these effects. You can also release the gas pedal and manually apply the trailer brakes with a brake controller as needed. Your trailer can start swinging back and forth behind you if you are not monitoring your surroundings and speed.

Look Twice While Changing Lanes

Your blind spots significantly increase with a trailer and it’s much harder to make quick lane changes. Give yourself plenty of space and move slowly from one lane to the other after double-checking your blind spots and the positions of surrounding vehicles.

Patience is Key with Passing

You also have to allow more distance and time when passing other vehicles. Give yourself plenty of room to get your vehicle safely up to speed with the trailer in tow. Be patient and remain calm at all times, even when other drivers may impatiently speed up and pass you.

Avoid Blocking Yourself In

Just because you can get in doesn’t mean you can get out. It’s a lot easier to get stuck or blocked in with a trailer than most people realize. Make sure there's plenty of space to make a complete turnaround or choose a spot where you can exit straightaway.

Practice Backing Up with the Trailer

Backing up with a trailer can be counter-intuitive for newbies. New trailer drivers should take some time in a parking lot or other spacious area to practice slowly driving in reverse. You’ll find that you have to turn the steering wheel left in order to move the trailer towards the right and vice versa. For most people it doesn’t feel right at first, so it’s definitely worth practicing in a safe environment.

Perform Regular Maintenance and Carry a Spare Tire

If you have electric brakes on the trailer, be sure to calibrate them so they are receiving the correct amount power. Follow the calibration procedures in your brake controller manual. Check the lug nuts with a lug wrench periodically to make sure they aren't coming loose. Grease the bearings on the axels every 10,000 miles or once a year, whichever comes first. Carry a spare tire, a lug wrench, and a jack that is strong enough to lift your trailer. It's tough to change a tire without the proper equipment.

Stay Alert

The #1 reason people get into accidents is because they are not paying attention, driving faster than they should, or simply lacking foresight. Look further down the road than you normally would because it takes longer to speed up, brake, change lanes, and turn with a trailer. This way you can spot and anticipate problems from a mile away.

Concrete starts decaying immediately after it cures. Even brand new construction can require leak seal follow up work. Older concrete structures are even more susceptible. 

Leaking concrete structures can be permanently repaired with concrete crack injection procedures using water-activated polyurethane grout. Pressure injection forces the material into leaking cracks. After the injection is complete, the polyurethane grout rapidly reacts with water to form a watertight seal.

The demo video below covers the 5 steps of concrete crack injection:

• Drilling Holes
• Flushing the Holes
• Installing the Ports
• Flushing the Cracks
• Injecting the Resin

This article is an excerpt from Episode 10 of Alchemy-Spetec's podcast The Injection Connection, featuring Alchemy-Spetec independent rep John Ziebell. Formerly the Vice President of Operations for Deneef Construction Chemicals, Inc., John has 36 years of experience in the chemical grout industry and is currently a member of the International Concrete Repair Institute (ICRI). (If you'd rather view or listen, an audio/visual version of this excerpt is posted at the bottom of the article.)

Charlie Lerman: What do you feel about this trend where we're seeing these large, major corporations coming in and buying up companies like De Neef and Prime Resins? How do you think that's going to affect the industry?

John Ziebell: I think it's a two-edged sword. The problem, when it was just the small people, when I first started - you had De Neef, you had Avanti, 3M was still in the business. We really didn't see a lot of other grouts. Occasionally, we'd see something coming from Germany, a couple of other guys that I can't think of right now. But nobody really had any good technical data or technical support. What I mean is if you looked at a data sheet, if you put a De Neef data sheet and Avanti data sheet and a 3M data sheet side by side on comparable material, they all had different test methods. Some of them used rubber industry, ASTM rubber, test methods. Some used ASTM plastic industry test methods, etc. So, it was really hard for a customer, for an engineer or somebody to compare apples and oranges to see exactly what he was getting.

The technical support was pretty weak and sparse in those days, but you did get more personal attention as a contractor. I think with the advent of the big companies, hopefully, they will spend the time and the money to develop better technical information, better tools, better case histories, things like that to offer to the industry. But I see guys out there now who are giving technical support and sales support in the field, who really don't know anything about chemical grouts. They have a degree. They're nice looking young people. They have a - well, they don't have a catalog in their hand anymore - they have an iPhone or some kind of cell phone. But they themselves when you talk to them at society meetings and stuff, they don't really know anything about chemical grout.

Charlie: I've seen that with some of the larger companies where, I mean, they're known for great customer service. But they cover such vast lines that they don't have that intrinsic knowledge of grouting that you need on that level. So, I agree with you on that.

John: And one thing that they could never do, they could never do something you do and something that I used to do before I got old - they could never get down in a hole, get down in a manhole or go underground in their coveralls and actually show a contractor how to inject. They don't even try; they don't even want to.

Charlie: Right. I had a proud moment, and I am known for wearing like severely grouted clothes and stuff like that, kind of people even make fun of it. But I showed up at a job site in the Portland, Oregon area and it was for a manhole; and as I'm walking up, there's the two classic guys you're going to picture for going down in a manhole. They're standing there and one is handing a dollar to the other one. And I said, “What's going on here? Just handing out money?” And he goes, “No, I bet him that you're going to show up wearing a suit.” So, they thought as a manufacturer rep, I was going to come out there in a suit and try to tell them how to grout. But I was wearing my waders and everything, ready to get down in there. So, that is, I think, an important thing in the chemical grout industry - having that kind of support.

It has become an Alchemy-Spetec annual tradition to re-post this classic holiday season safety blog I wrote a few years ago.  Merry Christmas and Happy New Year!

This time of year, most people will spend a little extra time with their loved ones.  It is also a time to reflect on the loved ones we miss that are no longer with us.  Like most of us, I know people who have either been lost or have suffered through a loss.  In those cases there was nothing that could have been done to stop it.  However, there are things that we can do to guard against job related safety hazards.

I've been fortunate enough to spend time in an OSHA safety training class.  It was required in order to be present supervising a project at a chemical facility.  Signing in at 6 AM, I’ll admit I was not looking forward to spending all day there.  By the end of the day I was glad that I went.

In an intro video, the narrator said that every morning when you kiss your loved one goodbye before you go to work, keep in mind that someone, somewhere will not come home from work that day.  Workplace accidents are almost entirely preventable.  Investigations typically find the cause quite easily. 

The class I attended contained a dozen or so modules, each one with a video case study followed by the teaching.  Every case study module covered a different accident where people didn’t come home from work that day.  All of them could have been prevented.  I learned about fire, electrical and chemical safety; as well as confined space, ladders, scaffolds, and working in trenches.  I have worked in the construction industry since my teenage years, so it was sobering to look back and think about some of the close calls I had.

If you're a contractor or industry related business owner looking for a good investment, send your employees to one of these classes.  It’s an excellent opportunity for them to learn safety principles that can protect you, your other employees, and your business from being lost.  It’s a gift that will keep on giving.  You don’t need Christmas as a reason to do this, but in the spirit of the season, you may want to make it the reason.

Merry Christmas and Happy New Year.

This article is an excerpt from Episode 10 of Alchemy-Spetec's podcast The Injection Connection, featuring Alchemy-Spetec independent rep John Ziebell. Formerly the Vice President of Operations for Deneef Construction Chemicals, Inc., John has 36 years of experience in the chemical grout industry and is currently a member of the International Concrete Repair Institute (ICRI). (If you'd rather view or listen, an audio/visual version of this excerpt is posted at the bottom of the article.)

Charlie Lerman: What are some of the most common mistakes you see over and over again?

John Ziebell: The two biggest by far are my pet peeves and they're my number one problems for all 36 years. Number one, the contractor does not know or does not determine the thickness of the structure that he's trying to drill into to seal leaks. He puts his injection holes too close to the crack or joint and he drills at such a shallow angle that - let's just say it's a 12 inch thick wall and he's actually intersecting the crack two or three inches in.

This leads into problem two - he starts pumping the grout and as soon as he sees the milky white liquid at the surface, he stops pumping and goes to the next injection hole, the next injection packer. So, he may have filled four or five inches at best of that 12 inches. All the rest of that crack is wide open, the water is still on the reinforcing steel, corroding it. It's finding hairline cracks, it's wicking off into other areas. So, those are number one and number two above everything.

Number three, and this is mainly contractors who make this mistake. A lot of old-time contractors simply do not want to use any type of grout that requires an accelerator because they think it's like an epoxy and once they mix it up, they've only got a short period of time before it's going to gel their pump. And I have talked until I'm blue in the face about this, but they still use hydrophilics on everything. Now, if you're down in a sewer, I know you've got a lot of experience in sewers and manholes and stuff, you're okay because it's wet all the time. But boy, you get up in the kind of thing that I've done mostly through the years here in Texas where you got wet-dry cycling, and you put the hydrophilic in there? It's almost assuredly going to weep at some point in the future. So, those are really the three biggest problems. The first two are the biggest by far.
