The Lab at Troutbrook Renewed as AASHTO Accredited Laboratory

June 11, 2020 – The Lab at Trout Brook , an independent testing department for TCC, ACP, Akona, Dakota Aggregates and Cemstone Companies is pleased to announce they have renewed their designation as an AASHTO – accredited laboratory. The American Association of State Highway and Transportation Officials (AASHTO) is a body that sets standards, publishes specifications, sets quality control protocols, and other guidelines. Accredited labs undergo rigorous on-site, third-party assessments conducted by ASTM (American Society for Testing and Materials). This assessment, which is conducted every 24-30 months, includes evaluation of the laboratory’s quality management system, records of technician training, a rigorous competency evaluation for each test method that the Lab is certified to perform, and equipment calibration records. Additionally, material samples are sent to the lab every year in order to measure technician and lab competency. The test results of these material samples are compared to all other certified labs and graded according to their accuracy. In addition to being certified to test concrete, aggregates and mortar, The Lab is now also certified for CMU testing. Areas of testing include CMU, rock, pavements, cementitious material, concrete, aggregates, grouts, mortars, fly ash, and lightweight aggregates.

David Morlock, P.E., TCC Materials Technical Services Manager, who led this enormous project said, “I am very proud of our technical staff’s work on this effort. They came together, supported each other, and demonstrated their training and professionalism. Their skill and execution brought us across the finish line along with the investment in state-of-the-art testing equipment. We understand the importance The Lab plays in meeting our customers’ needs, while offering the technical support they need, to be successful dealing with the architectural and design communities in the Midwest. They need the assurance that our products will perform as designed and our laboratory can provide that assurance.”

Featured Project: Mr. Car Wash

April 29, 2020 – Mister Car Wash in Eden Prairie, Minnesota recently completed a remodeling project that included the addition of stone veneer accents to existing brick walls. The remodel was designed so that the vertical stone veneer accent columns would appear as if they were unchanged since the building was constructed. With this in mind, TCC Materials recommended the use of ProSpec Masonry Veneer Mortar HB to direct bond the manufactured stone to the existing brick. This saved the contractor from having to apply lath and scratch coat and reduce the cost of heating, materials, and labor.

I was surprised and pleased with the performance of the ProSpec Masonry Veneer Mortar HB. Not only did it save my crew the step of lath and scratch coat, but they were able to install more stone per day than they usually would using traditional mortars. We definitely plan to use the ProSpec Masonry Veneer Mortars for future thin veneer installations.” ~Rob Scott, Owner of H&R Masonry

ProSpec Masonry Veneer Mortar HB is very different from traditional masonry mortars. It is a high-performance, heavy-duty, non-sag mortar that uses technology from the ceramic tile trade. With this formula, it is critical to measure the water during the mixing step. If not familiar with this mortar the tendency is to add more water as it appears too dry and unworkable. Once properly mixed the ProSpec Masonry Veneer Mortar HB can be applied to the substrate with a notched trowel and lightly back buttering the veneer before placing into the spread mortar. Typical mortar thickness is only ¼” installed and bucket life is 3-4 hours.

The non-sag properties allow for installation from the top down. This allows for cuts on the bottom course (less noticeable) and reduces mortar smear that can occur when working from the bottom up. Any mortar residue must be removed from the veneer before the mortar sets. Once mortar is set on the face of the veneer it can only be removed by grinding. The veneer was grouted the following day with Spec Mix Adhered Veneer Mortar. The installation was heated for at least 48 hours after completion of installation. The veneer installation of this project was approximately 600 sq. ft.

Featured Project: US Bank Stadium

August 5, 2016 – The 2016 NFL season is right around the corner and fans are especially eager for the first kickoff this year. For the last two seasons the Minnesota Vikings have been anxiously waiting for their home opener in the brand new U.S. Bank Stadium in downtown Minneapolis. A little over two and half years ago business leaders, elected officials, and Vikings fans partook in the ceremonial groundbreaking for the new stadium. Within the last month, M. A. Mortenson Co. wrapped up construction of the impressive 1.75 million square foot, 65,000 seat facility, a project that TCC Materials was proud to be a part of.

TCC Materials supplied masonry contractor Northland Concrete & Masonry Co. of Burnsville, MN with over 900 bulk bags of Type S mortar and 1,863 bulk bags of core fill masonry grout throughout the project. These products were used to set, bond, and fill masonry block throughout the stadium, including block in concourses, stairwells, locker rooms, and restrooms.

TCC Materials Spec Mix core fill masonry grout is a preblended mix with outstanding fluidity and increased cohesion over conventional core fill grout. It has excellent resistance to fluid grout mix segregation and easily fills masonry cores without voids and with no consolidations effort. With core fill being preblended and having no consolidation effort, it helps significantly minimize labor costs and provides batch to batch consistency.

TCC Materials Spec Mix Type S mortar is manufactured and packaged dry using specialized blending equipment and following strict quality controlled procedures. TCC Materials Type S mortar offers batch to batch consistency. This allows the product to meet the requirements ASTM certification and exceed contractor expectations with excellent workability and strength.

Both the grouts and mortars were supplied to the project in 3,000 lb. bulk bags which work in conjunction with the Spec Mix silo system, reducing time and waste on the jobsite. Additionally, some of the 3,000 lb. bulk bags utilized TCC Materials low-dust additive to reduce the output of dust as it become an issue in more confined quarters towards the end of construction.

TCC Materials low dust additive can be added to any TCC grout or mortar mix to reduce dust by 50-80%, helping to maintain clean job sites and prevent inhalation for employees and pedestrians in neighboring areas. For more information on low-dust additive including a video and FAQ, visit TCC Materials and search for “low-dust”.

U.S. Bank Stadium is the pinnacle of all stadiums, not only within the NFL and the United States, but also around the world. Visitors and fans will be amazed by the size and open feel of the stadium, providing an excellent environment for watching football games, and other exciting events.

Featured Project: Athlos Academy

March 31, 2015 – In 2014, New Visions Academy, one of the oldest charter schools in Minnesota, joined Athlos Academies of Boise, Idaho to create a new Pre-K through 8th grade public charter school in Brooklyn Park. The project specified 90,000 sq. ft. of stucco to be installed on the exterior of the building. Winroc Corporation supplied Quikrete® Pump Grade Stucco Base Coat in 3,000 lb. bulk bags to Stephen Donnelly Stucco for the base coat installation. The building is located across from Eidem Historic Farm, and opened for its first school year in Fall of 2015.

Quikrete Pump Grade Stucco Base Coat is a Portland cement based stucco, designed to be used as the scratch and brown coat in a 3-coat stucco application, or the first coat in a 2-coat application. This product contains special additives which prevent premature loss of mixing water and provide increased workability.

Featured Project: Franklin Avenue Bridge Restoration

The Franklin Avenue Bridge that links south Minneapolis to southeast Minneapolis over the Mississippi River is undergoing a two-year restoration and upgrade beginning in 2015. Originally completed in 1923, the Franklin Avenue Bridge or FW Cappelen Memorial Bridge (Hennepin Co. Rd. 5), was the longest arch of any bridge in the world with its 400’ long steel-reinforced concrete arch. The bridge has a span of 1,055 ft, is 55 ft. above the water, and a navigation channel width of 275 ft. The bridge was repaired in 1970 and 1971 and was listed on the National Register of Historic Places on November 11, 1978.

The work in 2015 will repair damaged concrete on the piers and arch work. An estimated 50,000 sq. ft. of repairs will be done with Shotcrete using approximately 1,000 cu. yd. of material. The preferred method of Shotcrete is a dry application where water is introduced to the mix at the hose nozzle. Some of the challenges of this project are the sloped river banks, height of the bridge, and detailing to match the original casting. The dry application gives the nozzleman more flexibility to start and stop shooting without worrying that mixed material would set up in the hose or pump. This saves significant down time by not having to clean out hoses or the pump.

The Shotcrete mix contains silica fume, poly fibers, air entrainment, and integral color pigment to closely match the color of the original structure and the repairs made in the 1970’s. Project Manager David Graham of PCI Roads worked with David Morlock of TCC Materials to formulate the mix designs that required approval from the Hennepin County Engineers and Historical Society. Kevin Fitch with Prism Pigments developed the two color matches.

TCC Materials was chosen to supply the Shotcrete because of the local technical and support staff and short lead times with the St. Paul plant only 11 miles from the project.

The bridge decking will be replaced in 2016. The decking will be precast off site at the Bohemian Flats Park and floated down river to the bridge and put in place by crane. The new deck will be wider to accommodate a bike lane and walkway. The railings will be rebuilt and different lighting installed. The total cost of the project is $43.1 million.

Featured Project: Worthington Event Center

July 20, 2015 – In 2013, the City of Worthington, Minn. worked with its community members to build a new event center which opened its doors to the public that spring. Last year they found they were having issues with the landscaping mulch blowing around due to the extreme Western Minnesota prairie winds. They City had talked about removing all the mulch and replacing it with rock, which would have been a costly update. As an alternative, the landscape contractor Ideal Landscape and Design, Inc. suggested trying TCC Material’s new Nurserymen’s Preferred® Landscape Loc® Mulch & Rock Bond to see if it would solve the issue before moving forward with the costly task of digging out the existing mulch and replacing it with landscaping rock.

Landscape Loc Mulch & Rock Bond is a non-toxic bonding agent which locks mulch in place to prevent movement often caused by wind, rain, children, pets, and other outside forces. This keeps the mulch in its intended location rather than migrating to other areas of lawn or landscape. Ideal Landscape and Design had recently heard about the innovative new product from Concrete Materials, one of their materials suppliers.

The plan needed to go through the stages of City government in order to receive their blessing. The plan was approved and the City saved time, money, and labor by applying the Landscape Loc Mulch & Rock Bond at the Event Center. They were pleased with the results and plan to use it again in the future. For more information on Landscape Loc Mulch & Rock bond, please visit the Landscape Loc Mulch & Rock Bond product page on our website.

TCC Materials Updating SDS and Packaging to Comply with new OSHA GHS Regulations

March 1, 2015 – TCC Materials has been busy updating their information in order to comply with OSHA’s revised Hazard Communication Standards. The transition has been a two-part process for TCC Materials. The first step began at the end of 2012 as TCC Materials began the transition from the old MSDS (Material Safety Data Sheet) format to the new SDS (Safety Data Sheet) format. The new format will have 16 distinctive sections. Sections 1-8 will cover general product information including identification, hazards, composition, safe handling practices, and emergency control measures so that is easily accessible to jobsite workers. Sections 9-11 will cover more technical information including physical/chemical properties, stability/reactivity info, toxicological info, and exposure control info. Sections 12-15 will cover ecological, disposal, transport, and regulatory considerations while section 16 covers other information. The SDS’s for most TCC and Akona products have already been updated and are available on the individual product page for each product on

The second step was to comply with OSHA’s adoption of the United Nation’s Globally Harmonized System of Classification and Labeling of Chemicals (GHS). This step began in early 2013 as TCC Materials started the process of updating their product bags and labels to comply with either the OSHA’s GHS labeling requirements, the Consumer Product Safety Commission requirements, or both depending on the intended product use. Customers can expect to see the revised labels with the required health & hazard information in early 2015.

Featured Project: Loring Park Minneapolis (LPM) Apartments

February 15, 2015 – TCC Materials began supplying product to the Loring Park Minneapolis (LPM) Apartments project in 2013. Due to the extremely confined space of the jobsite, the masonry contractor Weise Masonry needed to get creative with products and equipment.

The footprint of the project took up an entire city block which left no outside staging area for silos and product. Additionally, there were issues with using gravity-fed silos on each of the 36 floors due to the restrictive ceiling heights of the high-rise apartment complex. The normally generous 9’ Loring Park Minneapolis (LPM) Apartmentsceilings did not allow for enough room to load a silo with a 3,000 lb. bulk bag of mortar or grout. This prompted Weise Masonry to contact their TCC Materials sales representative who was able to provide a powered auger-silo which sits lower to the ground allowing for enough room to load the silo.

Since Weise Masonry was dealing with such confined spaces and close proximity to downtown Minneapolis, TCC Materials saw this project as a unique application which could utilize their new Low-Dust Additive option for mortars and grouts. The Low-Dust Additive is designed to reduce the amount of dust generated during the handling and use of dry concrete, masonry, shotcrete, and other mixes by 50-80% without compromising the strength or workability of the mix. Low-Dust Additive is an option for use with most TCC Materials products. For a video of the product being used on the LPM Apartments, please visit the Low-Dust Additive product page.

New Akona Plant Set to Open for Business Early 2015

January 23, 2015 – TCC Materials announces that their new Akona facility in Rosemount, Minnesota is expected to be fully operational in the first quarter of 2015. TCC Materials acquired the existing Rosemount facility in February, 2014 and has been adapting the facility to accommodate their operations. This facility will replace their current facility in Maple Plain, Minnesota to become their new super-plant for specialty products. The plant’s manufacturing capabilities will include a wide variety of products for the concrete and masonry industryAkona Specialty Plant - Rosemount, Minnesota, including their new line of ProSpec commercial concrete repair products.

The building is conveniently located at the intersection of County Road 42 and Biscayne Boulevard in Rosemount, just a few miles from TCC Materials’ sister company Dakota Aggregates mining operation and just 13 miles south of their corporate headquarters in Mendota Heights, Minnesota.

The plant has inventory in stock and will soon be making the transition from shipping out of the Maple Plain facility to directly shipping out of the new facility.
