Polyurea Coatings Provide Safe, Reliable, and Flexible Waterproofing

by on September 21, 2020





Cities across the country depend on decades-old water reservoirs, ponds, and tanks to store potable water as well as for fire suppression. 


Although steel and fiberglass are mostly used for smaller tanks, the largest and most enduring outdoor tanks and reservoirs that contain millions of gallons are constructed of cement or asphalt. Unfortunately, several factors can cause these constructions to develop sizable cracks through which large quantities of liquid can escape (exfiltration) or enter the water supply.

When this happens, facility managers must decide whether to demolish and reconstruct the aging structure or find a way to extend their service time. Fortunately, advanced polyurea coatings and liners are showing ideal for the tank, pond, and reservoir restoration by presenting strong, flexible waterproofing that not only links large existing cracks but can elongate up to 400% without breaking.





Concrete/asphalt cracking

Cracks can occur in aging concrete reservoirs and tanks for numerous reasons ranging from ground movement to daily or seasonal heat changes that cause expansion and contraction. The weight of water in a big reservoir or tank can also cause concrete to move many inches. In doing so, tiny cracks in a drained tank can open to cracks 1/4" or larger when filled with water.

To address the issue, waterproof layers such as epoxies are often applied to the exterior. However, these traditional coatings lack the flexibility to budge and sway with concrete or asphalt and crack.

Instead, water facility managers turn to polyurea coatings and linings, one of the few protective coatings that can work on the expansion and contraction cycles of substrates such as asphalt, steel and concrete. Some advanced polyurea coatings have high tensile strength and the flexibility to stretch 400% and sizable bridge cracks.







Rehabilitation instead of demolition

Redstone Arsenal, a large U.S. Army base in Huntsville, Alabama, had a decision to make: demolish or repair an important, working, 5-million-gallon water tank. The tank, built-in 1941, has had a beneficial life as a water storage tank for fire suppression, as well as a back-up water supply. However, the tank had numbers of cracks and leaks and was losing water at an significant rate.

The tank was missing a significant amount of treated drinking water, which is more expensive. The Army base had attempted to use different liner types over the years, but those were not working adequately.

Redstone Arsenal's Public Works Department evaluated their options for more than ten years with no apparent solution. After the current success of a polyuria-rehabilitated water storage pond adjacent to the tank, they recognized that they could use a similar approach. The contractor on the pond was also awarded the tank project.



The spray-applied waterproof coating creates a seamless, waterproof, durable protective liner that stops leaks and strengthens the entire storage structure's integrity. It is designed to withstand decades of freeze-thaw cycling, wide variations of heat and humidity. In the late 1990s, Parsons Brinckerhoff issued a 75-year lifespan on the famed Boston Tunnel Project.

With minimal crack repair and surface preparation, the polyurea coating can be thick film-applied directly to the concrete, asphalt, or similar substrate. An alternative application method that can sometimes mitigate the need for surface or crack repairs is to pre-spray the polyurea to geotextile fabric panels placed above the onsite substrate, fusing the panel edges with more polyurea.

With either application process, the polyurea coatings exhibit preferred physical properties such as high elongation, crack bridging, hardness, and tensile strength to create a robust industrial liner that protects, strengthens, and waterproofs concrete reservoirs and vessels.

The polyurea's ability to set and cure fast also reduces water tank or reservoir downtime. This can translate into thousands of dollars per hour savings in facilities requiring potable water and a source of emergency water for fire protection.

The polyurea sets up in seconds and can be put back into service as fast as an hour. It can take days for epoxy to cure enough to do the equivalent. The time saved can provide tremendous savings to a facility. 


After repairing all cracks over 1/8″ wide with a concrete repair grout, the contractor primed the 5-million-gallon water tank's concrete surfaces with primer and applied 80-100 mils of pure polyurea. The walls were completed first. Next, they removed the heavy equipment from the floor. The tank base was re-cleaned and primed before the polyurea's last application was applied to the floor. From start to finish, the project lasted two months.

Two years later, both Redstone Arsenal's polyurea-rehabilitated 5-million-gallon water tank and the water storage pond adjacent to the tank have been investigated and remain in excellent shape, with decades of extended life expected.

Guide to Products and Equipment

The procedure for coating these types of systems is very easy. A clean concrete surface area with a rough profile can even be sprayed on without any primer/sealer. If there is running water, the ArmorCrete Primer/Sealer can offer an immediate barrier, and the 510 can be sprayed right over it to firmly coat and seal that area.



The sanitation protection and rehabilitation market has actually long utilized elastomeric coatings to kept existing structures and devices in working order. ArmorThane polyureas like the HighLine 510 have actually shown to supply the following benefits to concrete and steel rehabilitation tasks, and particularly to the sewer and sanitation market.

1. Increased Use protection- the service length is considerably improved, in some cases even by a factor of 4 or more.
2. Corrosion Resistance- destructive elements that might possibly cause structural failure with time are obstructed by the chemically resistance polyurea coating
3. Easy to Tidy- even a basic cleaning can eliminate refuse and natural develop
4. Reduction of Bacterial Development-- The mix of the inert and impermeable nature of a cured ArmorThane coating does not permit bacteria to "acquire a grip" and consequently, the much easier to clean environment sees a slower build-up of bacterial hairs.
5. Sound Dampening-- the motion of layered containers, or the effect and collision of refuse to the structure does not produce the exact same level of noise. In addition, crashes within the coated structure have their sounds reduced to those outside of the structure who would typically undergo the noise of moving sewage.

ArmorThane elastomeric coatings are utilized the world over. Impact and corrosion protection in mines in Peru, roofing coatings and waterproofing along the coast of Nigeria, Truck and heavy equipment protection in Australia, and even explosive blast mitigation and protection for the US Armed force are all effective applications which reveal the strength of our products, and our ability to discover the best material for each application. For this type of concrete rehabilitation application, specifically with its wetness heavy environment, for the purpose of a sanitation control structure, the HighLine 510 will have superior efficiency to any other coating choice.

HOW POLYUREA COATINGS PREVENT DISEASE

by on January 17, 2020


Polyurea and the Food Processing Market
What's one of the greatest concerns of the food processing industry? As you may guess, it's not almost taste or supplying sustenance. Instead, food processing plants have a significant obligation. Without appropriate protection, contamination represents a significant health risk. The reality is that polyurea coatings can lower the intrinsic dangers associated with all kinds of exposure.

If you remain in business, you currently know how foods get contaminated. Some things are simpler than others to manage. For example, some food processing plants do not pay enough attention to securing surface areas. All things thought about, excellent practices are critical to guaranteeing food is prepared effectively and in a safe environment.

If you listen to the news, you'll observe increasingly more cases of food contamination. Fact be informed, there's a high possibility for the growth of germs and bacteria in food processing plants. It's not like the prospective harm is noticeable to the human eye. In fact, it's in some cases the things we can't see that are the most hazardous of them all.

DANGER DIRECT EXPOSURES IN THE FOOD PROCESSING MARKET
More than likely, you currently understand the significance of keeping the work environment tidy. For sure, there are a variety of disease-causing representatives that can penetrate completion product. Listeria is among the most fatal. Those impacted with it will wind up with listeriosis, which represents a big offer. In fact, the Centers for Disease Control and Prevention (CDC) reports that one in 5 people with listeriosis will pass away.

Listeria monocytogenes is in fact a bacterium. Federal government guidelines such as the Food Security Modernization Act offer assistance concerning food production in addition to safe handling of foods. On the other hand, listeria is not the only potential threat.

What about the effect of unwanted animals in the food processing location? It's no big trick that rodents, cockroaches, and flies are attracted to all kinds of components. That said, pest control is not enough. They not only carry illness through various bacteria-- but they also bring it from one place to another.

POLYUREA COATINGS IN THE FOOD PROCESSING INDUSTRY
The concept of creating an environment that's simple to clean is vital. Believe for a moment. Even if you're preparing in the house, you know the risks connected with working with chicken. Unless you're careful, there's an opportunity of infecting surface areas with salmonella bacteria. As soon as once again, this opens the capacity for severe health problems.

Employees might believe it suffices just to reject preparation locations and hastily proceed to the next job. The issue? If there are indents or even small cracks in the surface-- the bacteria seeps in and invites the start of cross-contamination.

How can polyurea coatings assist with this? It's a great deal much easier to sterilize a surface if it's been properly secured. Polyurea coatings serve as a sealant. They ward off possible issues, such as seepage of sitting liquids or wetness.

Other areas of a food processing plant might be of issue. What about broken concrete or dripping pipes? Polyurea coatings also play a crucial function when it comes to protection of the workspace.

Reshaping Processing Plants Using Polyurea

by on January 17, 2020



With news of more food processing facilities pulling product off the market and having to shut down due to possible contamination from Listeria Monocytogenes, the concern of plant sanitation, as well as style and building structures, are at the forefront of the agenda for those in the industry.

At issue are food and meat processing plants located in aging industrial buildings with extensive ware and tear, in addition to ideal angled building. In these plants, walls and ceilings are typically built with angled steel, i-beams, concrete block, interlocking metal and fiberglass panels, double-t ceilings and tiles with concrete grout.

This supplies a virtual breeding ground for standing water, dirt, dust, mold, and pathogens such as Listeria, E. Coli, and Salmonella. With many fractures, pits, and seams, plants are at danger in spite of aggressive power cleaning and chemical sanitation strategies.

Plant Recalls from Listeria
The fallout from a public recall due to Listeria extends well beyond lost earnings and extended plant shutdown as well as a decrease in overall business value. Lawsuits, due to customer health problem and even death, along with the disastrous impact to the brand name's credibility, can put a processor out of service.

The difficulty with Listeria is that it is proficient at evading detection. It can aerosolize or connect to equipment and individuals, and will prosper in cold temperatures. As an outcome, it is difficult to control in the processing environment. To fight this pathogen, lots of centers depend on a robust sanitation program to avoid Listeria from getting in or polluting the environment. In addition, many processors participate in continuous environmental sampling programs to keep track of the efficacy of those efforts.

If any bacteria or contamination is discovered, called "testing hot," it can lead to an instant shutdown. Closing down a food processing plant that is running 24 hours a day, 7 days a week, can cost the processor millions in lost profits. There is also the danger of fines by the USDA for recurring violations.

In the majority of instances, business just react to a positive test by performing magnified cleaning and sanitization. Once the company's follow-up tasting of the affected websites is negative, the problem is normally thought about to be dealt with.

In addition to issues about bacteria, contamination likewise comes from facility maintenance concerns, such as breaking paint, spalled and broken concrete, and areas in the walls and ceilings that can gather dust, dirt, mold and other contaminants.

Perpetual Cleansing, Painting
Until now, the expensive and labor heavy solution was merely to clean up more frequently and mitigate the issues utilizing FRP panels or layer upon layer of paint to try to create a cleanable surface.

The aggressive cleaning agents like bleach and cleaning agents and heavy high pressure power cleaning cycles take a heavy toll on the paints, epoxies, concrete, fiberglass and metal surfaces eventually use them away until they need a total replacement, or even worse, they jeopardize a plant shutdown and or fines.

This is an extremely costly, labor-intensive program that duplicates itself in perpetuity at practically every food processing plant throughout the nation.

To resolve this issue, new patented techniques are being used to deliver a complete rehabilitation of the walls and ceilings, typically throughout planned maintenance weekends.

Many other coatings take 1-4 days just to treat, which is too long when you require to get the plant back online. Polyurea cures within minutes. Additionally, the space is "reshaped" through this procedure so just smooth, curved lines stay to remove areas where water, dirt, grime or pathogens can collect.


Among the key elements of the Fixxus process is application of an incredibly fast curing, pure polyurea coating designed for usage in food processing plants. Given that the material is spray used, it can be applied quickly by qualified applicators and constructed up to any required thickness and formed into the modified wall and ceiling design. Polyurea is the only coating system readily available that can create a monolithic surface area in the brief time frame needed to minimize plant downtime.

The majority of other coatings take 1-4 days simply to cure, which is too long when you need to get the plant back online.



Industrial Systems makes use of a special, private label formulation of pure polyurea for food contact facilities from ArmorThane, a worldwide provider of high-performance polyurea coatings, liners and joint sealants for a wide variety of industrial environments. The company uses two systems that are third-party ranked for FDA Direct Food contact.

Due to the aggressive nature of plant wash downs, a custom-made polyurea topcoat is required to finish the process., The final topcoat creates a very slick surface, making it difficult for standing water, dust, dirt, or bacteria to take hold. To finish all this work, Fixxus deals with the food centers to strategy and optimally time rehabilitation operations.

Before any coatings are used, there are several actions to restore an aging food facility., No quantity of cleansing will effectively prepare a surface that needs repair. So the initial step is to resolve any areas with spalled or split concrete, chipping and peeling paint, or heavy corrosion.

The next action is an intensive cleaning process to remove grease and gunk and other surface area contaminants that build-up as an outcome of meat processing, cooking, and basic facility maintenance. This involves using specially authorized wash down options and self-contained high powered water blasting techniques. All holes, voids, joints, and penetrations are filled, along with additional adjustments for the reshaping. A combination of concrete and molded foam products are utilized to transition any flat surface areas from 90 degrees to 45 degrees to avoid standing water from accumulating.

These areas usually consist of the cove joint from wall to floor, steel I beam bases, welded and frame bolted angle iron, and gaps in the existing construction or wall/ceiling fascia. Standing water is one of the numerous contributing aspects for Listeria and other pathogens, in addition to mold and corrosion. Finally, every piece of devices, pipe, flooring, and other exposed locations must be wrapped in plastic or covered prior to spraying starts.

In numerous applications, such as the within of big tanks, sprayed polyurea is not required to be cosmetically appealing.

For food processors in aging centers this type of total interior wall and ceiling rehabilitation-- regardless of the surface or substrate and level of disrepair-- might be the quickest method to break the cycle of constant degeneration and ongoing repair, while decreasing danger of pathogen-based item recalls.
