Spetec PUR H100 is widely specified by engineers for the cut-off of large water leaks. It is a one-component, closed-cell, hydrophobic, water-reactive, solvent, and phthalate-free, low viscosity resin. Its low viscosity and hydrophobic properties make it ideal for both soil stabilization and cutting off large water leaks.

Spetec PUR H100 Applications

There are a plethora of applications for Spetec PUR H100. Some specific uses include cutting off sewer water leaks and soil stabilization around sewer structures. Other uses include water cut-off of leaks in foundations such as diaphragm walls, piling sheets, and secant piles. Spetec PUR H100 is also good for stabilization and water cut-off of large cracks, voids, and gravel layers. It has also been used to stabilize soil and anchors in porous geology and gravel layers in concrete structures. In addition, it is an ideal resin for probe grouting below-grade pipes and manhole injections. Last but not least, injections in combination with cement-based grout work very well with pre and post injections in mines, tunnels, pipe jacking, drill & blast, and TBM applications.

Spetec PUR H100 Advantages

The one component, closed-cell structure allows the cured polyurethane resin to seal large water leaks in cracks and joints permanently. It is also possible to alter the reaction times by adjusting the percentage of accelerator. When cured, it exhibits high strength and good chemical resistance. This in turn makes it harmless to the environment and resistant to biological attacks. Not to mention it is also certified for contact with drinking water.

• Manholes

• The Grand Canyon

This is not a game of which one doesn't belong, as they all channel water and can cause erosion. The Grand Canyon is breathtaking. Likewise, washouts or sinkholes caused by leaking and neglected infrastructure are breathtaking - but in a completely different way. They're breathtaking in regard to the high costs of emergency repairs and the potential damage they cause.

This quote, from an article on KCCI.com, sums it up nicely...

“At first, crews resurfacing the pavement thought a large piece of machinery had fallen into a sinkhole 10 feet deep… It turns out an original clay storm sewer pipe had disconnected, leaking water for what appears to be a long time, eroding the earth around it.”

There is no downside to fixing these common infrastructure issues before they get out of control. Any repair costs are quickly offset by the reduction of sewer water requiring treatment. Who is not for lower sewer rates, a healthier environment, longer-lasting infrastructure, and fewer manmade washouts/sinkholes?

So why don’t we address infiltration more? It is as simple as the old adage "out of sight out of mind". Infiltration is a preventable and treatable sewage collection system problem. We have neglected our infrastructure for too long and we need to raise public awareness of the issue.

We at Alchemy-Spetec not only manufacture quality polyurethane chemical grouts for these types of repairs, but we also provide top-notch training and support for leak seal crews. Call 404-618-0438 and let us know how we can assist you in raising awareness about or repairing infiltration. We are all in this together.

The Central Davis Sewer District (CDSD) is a publicly owned collection system and water treatment plant that serves three local cities in Northern Utah. With a new highway being constructed just outside their facility, a new pump station had to be installed on the premises. After installation of the new pump station, a large leak appeared in the manhole which caused it to fill up with about 10 feet of water. The CDSD contacted PolyFoam Solutions to see what could be done to seal the leaks. The PolyFoam Solutions crew pumped all the water out of the manhole and discovered that two of the manhole’s horizontal joints had large leaks. These leaks were allowing about 10-15 gallons per minute (over 20,000 gallons per day) of water to infiltrate the pump station.

Powerful Polymers

PolyFoam Solutions worked closely with Charlie Lerman, Alchemy-Spetec's Director of Technical Services for the Leak Seal Division. Together, they devised a plan to seal the large leaks using Spetec PUR F400. Spetec PUR F400 is a solvent and phthalate-free, water-reactive, hydrophobic, closed-cell, low viscosity, shrink-free, flexible, one-component polyurethane injection resin designed to stop water leaks. It is also certified to NSF/ANSI/CAN 61 (approved for contact with drinking water).

Painless Procedures

The crew drilled four holes around the lower manhole joint and then installed injection ports. As they pumped the polyurethane grout into the ports, it began to travel around the joint, sealing the leaks. Once the grout had traveled as far as it could from one port, the technician moved on to the next port until the entire joint had been sealed watertight. They used oakum to temporarily seal some of the larger leaks until the grout had time to cure. The upper joint only required 3 port injections due to the speed at which the grout traveled.

Rapid Results

The crew only took about 3 hours to completely seal all of the leaks and return the manhole to service. There was no way the leaks could have been left un-repaired due to the water treatment cost and the potential damage the erosion would have caused. Replacing the manhole would have easily cost three or more times the price of grouting. In this case, the community wins as many tax dollars are being saved.

From hairline concrete cracks to gushing leaks, virtually any defect can be sealed with the Spetec series of polyurethane resins, optimized for leak seal applications.

Leaking concrete structures can be permanently repaired with concrete crack injection & curtain wall procedures using water-activated polyurethane foam. Pressure injection of these liquid polyurethane resins forces the material into cracks and joints, behind walls, pipes, manholes, and any kind of infrastructure in need of controlling water intrusion and leaks. After the polyurethane injection is complete, the polyurethane resin rapidly reacts with water to form a watertight gasket to seal off the affected areas.

The products offered by Alchemy-Spetec deliver the ultimate solution for hairline cracks, gushing leaks, and other leak seal issues.

One of the many joys of my job is going to all corners of North America and participating in unique projects. While I am a seasoned traveler, cement is not. Cement grout often requires heavy equipment. Shipping cement grout and related equipment can be expensive. While often not a concern for most projects, it is a driving factor for remote locations.

I have been involved with numerous projects in which cement grout would be an acceptable repair and more cost-effective than chemical grout - until the project location gets factored in. Dams are found in many remote locations. The very remote ones are often built using a temporary road that can handle heavy construction traffic. Fast forward some years and these roads no longer can support cement trucks or other heavy vehicles.

Chemical grouting equipment can easily be loaded into a pickup truck or even on the back of an ATV. While the material cost of polyurethane chemical grout is more than cementitious grout, getting polyurethane materials and equipment to a remote site can be a lot less expensive.

Lightweight polyurethane is much easier to mobilize with a small to non-existent footprint. This means it is less disruptive to sensitive sites. (Seawalls are a good example where chemical grouting can be done without tearing up the home owner’s yard with heavy cementitious grouting equipment.)

There are many factors to consider for every grouting job. It helps to have the Grout Geek and Alchemy-Spetec in your corner to help design the right plan for your project.

Polyurethane chemical grout injection can be a bit of a Pandora’s box at times. So, what can be done to help combat some of these uncertainties? Well, how about the easiest and most cost-effective solution first. Oakum! Not only is it amazing what you can accomplish with it, but it is vital to have on every job. YES, I SAID EVERY JOB.

There are only two things that have to happen for successful water mitigation. One, get the grout to the right location. Two, keep it there long enough to react. With tight cracks, it can be difficult to get the grout to travel in the crack, but once you get it there it is good to go. With wide cracks or high flow leaks, getting to the right place is easy, but keeping it there long enough to set up can be challenging.

You can use oakum to control grout and keep it where you want it in the crack or joint. Remember we are doing the injection work to stop the flow of water, so let’s make the least amount of holes possible in the concrete. But what does that have to do with oakum? Cracks are irregular, and often have sections that are wider in some sections. When this wider area is at the surface it can allow an easy escape path for a grout under pressure. That means you are wasting grout and not getting it where it needs to be, deep in the crack. Sure, if you have raw resin coming out of the crack you can just wait for it to cure. Once cured you cannot reinject that packer, so it is best to surface seal that crack and stop or slow down the loss of grout. This allows you to continue effective pumping into the crack or joint.

If the crack or joint is wide, grout impregnated oakum can be packed in place. While messy, this is the equivalent of finger painting with chemical grouts and is an easy process.

If you're thinking "I have rags, I don’t need oakum", think again. Oakum is stronger, can be pulled apart into just a few fibers if needed, and can be stuffed into very tiny defects where rags cannot fit.
