Sika - Building Trust

When two road trips meet!

The MTU tests as close to ASTM standards as possible.

Loveland, CO -Sika’s mobile technical unit (MTU) is a high-tech laboratory on wheels. Marc Boudreau and Robert Kruck, the real Sika road-trippers, travel to ready mix and precast concrete customers across the country to optimize mix designs and troubleshoot problems. As you can imagine, mailing samples back and forth to a Sika lab can be a tedious process when testing a new mix design, especially for a new customer that wants to get up and running. Marc and Rob test samples onsite to find the ideal ratios between Sika’s concrete admixtures and the customer’s materials. While Marc and Rob’s combined experience have led them to recognize most issues, each stop provides a new challenge for the MTU.

 

Each cabinet and drawer has a different tool or piece of equipment for testing.

The unit is deceptively well stocked with equipment. It has the capability to mimic and control a wide variety of variables that may affect the customer’s mix design. Marc explained that the most useful tool is the Calorimetry System (Sika named it Sika SemAment System) developed by Sika Technology AG. The system can relate the heat signatures between different samples throughout the curing process. Marc will use this information to alter the admixture concentrations until an optimal mix design is reached. As various types of aggregate and sand can react differently with Sika’s concrete admixtures, each customer will have a unique mix design. This process involves a great deal of problem solving, and so the MTU may be stationed at a site for an indefinite amount of time. Also, some customer’s may have specific requirements for their mix, such as sulfur resistance or a quick set time. As Marc mentioned, no stop is ever the same.

 

We were surprised by some familiar faces, Danny and Erica, from the Lyndhurst offices. Danny and Erica spent the week working in the MTU and helping Marc as needed. Extra hands are always helpful in the MTU, because many samples need to be tested to find the best design. Customers can also work on the design themselves with Sika’s SCC Mix Design Tool. Keep an eye out for the MTU on the road, the next stop is Bakersfield, California!

The real Sika road trip!

  • Tomorrow Sika is hosting #GiveBack day with @rebuildingtogether in San Francisco.  Last year, we provided some much needed updates to a Community Center in Chicago, as well as donating a Sika roof system which @protechnj101 installed! We look forward to seeing everyone tomorrow at Adam Rogers Park for another great volunteer day! #sikaeveryday #throwbackfriday
  • Summer vacation time is coming to an end.  As you are traveling back home, you'd be surprised how many #SikaSarnafil roofs you pass by on a daily bases. 
Pictured here is the Cyril E. King Airport in St. Thomas U.S. Virgin Islands which is just one of many airports covered by the leading thermoplastic roof membrane!  #Sikaeveryday #successwithsika #safetravels #roofinglife #constructionworld
  • What a stunning sight on a Monday morning! Not only is the light grey #SikaSarnafil Decor roof protecting US veterans from the Nevada elements but it is also helping cut down energy cost by 50 percent (compared to the previous standing seam metal roof) #SikaEveryDay #Successwithsika #sustainabilitymatters #sustainableroofs

  • The National Museum of the Marine Corps carries on their mission:  to commemorate the past, present, and future of the Corps. 
James Myers Company was called upon to install a new #SikaSarnafil roof on the building expansion that would house new exhibits focusing on Operation Desert Shield and Operation Desert Storm such as the Genesis II, a fully restored M60A1 battle tank, a F/A-18 Hornet jet, expanded educational facilities, and a one of a kind theater. #roofinglife #constructionworld #successwithsika #sikaeverday
  • Sika's products can turn up in unexpected and remote locations.  Any guesses on which country this picture was taken?  #sikaeveryday
  • The @theloftsatrivereast  roof in Chicago, has many different elements on it, including a party deck, elevator penetrations, lots of new duct work, HVAC equipment and a vegetated green roof. “Anything you can think of that can be on a roof is on this roof,” said August Mitchell, vice president of construction for Ghafari Associates of Chicago, the construction manager of this project. #SikaSarnafil #GreenRoof #sikaeveryday #successwithsika #ChicagoRoofing #ChicagoGreenRoof #sustainableroofs
  • How strong is Sika Post Fix?  This chain has been embedded in one bag of Post Fix to secure a bike rack.  This innovative product was the prefect replacement for a bag of concrete - no water or messy mixing needed and it sets much faster. #sikaeveryday #concrete #sucesswithsika
  • Sika admixtures are playing a key role in repairing the Oroville Dam Spillway back to its original design capacity. In February 2017, engineers noticed concrete erosion on the flood control spillway at the Oroville Dam. Rising water levels beyond the dam’s height required use of the emergency spillway for the first time in the dam’s history.  What concrete wasn’t washed away on the lower part of the main part of the spillway is being removed to allow for construction of a replacement.  #Concrete #OrovilleDam #Oroville #SuccesswithSika #SikaEveryDay #Construction
  • Turn your rooftop into a valuable, long-term and highly cost-effective advertising piece like the Bankers Life Fieldhouse, home to the NBA Indiana Pacers and WNBA Indiana Fever. 
Midland Engineering, South Bend, installed this custom logo made from #SikaSarnafil evergreen roof membrane. #Sikaeveryday #successwithsika #roofinglife #roofingworld
  • The Coastal Biology building in Santa Cruz supports research and teaching on coastal conservation, ecology, habitat restoration, climate change impacts and policy. RP Coatings of Hayward, CA, an Elite Sikafloor partner, installed a custom Comfortfloor System in three colors to help complete the stunning facility. In addition to laboratories and offices for faculty and researchers, the building will feature a 125-sear seminar room; a core seawater laboratory; analytical labs and rooms; and meeting spaces and conference rooms. #flooringworld #sikafloor #sikaeveryday #successwithsika
  • The Federal Aviation Administration (FAA) requirements for  aesthetics and a watertight roof for the LAX Air Traffic control tower was met with a #SikaSarnafil Decor roof system. @bestcontractingservices took on the challenge to install this roof while the building was still occupied. #roofinglife #roofingworld #sikaeveryday #successwithsika
