This post is part of the Alchemy-Spetec Contractor Lens series, featuring views, news & case studies written by our customers. This article, written by J.R. Crowell of Helms Polyfoam, explains why polyurethane slab lifting requires less downtime than alternative repair solutions (and why that's an advantage for property owners & managers).

When deciding on a repair plan for a commercial facility, no matter the type of repair, one very important factor to consider is downtime. That old expression “time is money” is not a joke, especially when we are talking about downtime for a business.
A large portion of repairs in the commercial market, whether it be concrete lifting, soil stabilization, or void fill, are in areas with high traffic. This traffic usually consists of forklifts, heavy equipment, and semi-truck and trailers, all of which have a dollar amount tied to their load or run time. Every minute they are aren’t running is a minute they 1) are not making money or 2) are losing money on a late delivery or late project completion.
How is Polyurethane Foam Beneficial to Downtime?
Small Footprint:
Polyurethane repairs generally require only one truck or trailer or even smaller equipment. Crews can work around high traffic areas and times to ensure that daily workflow is minimally impacted.
No Excavation:
Repairs are completed using polyurethane resins injected through a 3/8” – 5/8” hole. These injections are completed from the equipment mentioned above, requiring no heavy equipment. No heavy equipment means that employees will not have to alter their site flow to navigate around a large excavator or concrete truck.
Fast Cure Time:
When it comes to concrete lifting, polyurethane resins begin to set up within 15 seconds after injection and are 90% cured within 30 minutes. This means that by the time the crew leaves the site, the treated areas are ready for “business as usual” and can allow normal traffic. Compare this to demolition and concrete pouring (days of labor and curing), and you see a huge savings on downtime.
If time truly equals money, and we all know it does, the above three reasons show how a polyurethane repair can keep downtime to a minimum and maintain an efficient workflow, thus keeping the bottom line in order. When comparing estimates of various repair methods, don’t get stuck on the dollar figure, always compare the total repair plan and what it could cost on the back end.




Storms, tidal action, and soil erosion constantly cause damage to seawalls. It is essential to identify any problems as early as possible. Here are the most common warning signs of seawall failure:

For hand sanitizers, the CDC website recommends a >60% ethanol, or >70% isopropyl version in healthcare settings. However, the CDC is only one agency. Comparatively speaking, the FDA will adhere to their own claims as to what is acceptable in healthcare, food processing, home use etc. And within each of these segments, there will be different approvals for different uses. For instance, a poultry plant will require specific claims to the efficacy to kill salmonella. The resulting EPA claim registration will be different for the chemical used to clean a cleaver to butcher a chicken compared to a surface on which the chickens are stored. In addition to this, the same product may have registered claims to kill 99.9% salmonella in 60 seconds, while another producer had the same claim, for the same chemical, approved with a 90-second kill claim. These could be different products at the retail level. Also, EPA approval does not constitute FDA approval, and vice versa. It’s easy to see that agency regulations can be very confusing. 

The INJECTR Series single cartridge houses grout and accelerator in two separate interior compartments. The grout and accelerator are thoroughly blended when injected through the static mixer. This cartridge is compatible with standard caulk guns. 
Seawalls are built to create a strong and stable barrier between a body of water and adjacent land, but why do they fail over time? Here are three common factors that can damage a seawall.

Major water infiltration in precast manholes often occurs at the pipe penetrations. Failure to seal these leaks quickly could lead to the loss of thousands of dollars. It can also suck in soils and fine particlesThis process creates voids outside the manhole. With time, these voids grow larger and become sinkholes.

What happens when a joint in a precast manhole begins to leak? The answer is it may as well be leaking money.
