Grasscrete Provides Solution to Storm Water Management for City of Denver

The City and County of Denver needed to make improvements to the existing 38th & Holly Detention Pond. During small and larger storm events, water was collecting in Holly Street at depths up to approximately 1.5 feet. The water would then overflow the pond embankment along Holly Street to enter the pond and caused severe erosion to the embankment, meanwhile creating on-going maintenance concerns and repairs.

The City and County of Denver moved forward with plans to significantly re-landscape the detention pond along with planting trees for pedestrian shade to mitigate the issues, prevent future erosion and provide storm water management.

In order to tackle the innovative decorative concrete design by the Landscape Architects, Stream Design, a gabion drop structure was constructed utilizing architectural concrete finishes to create this storm water improvement at 38th & Holly Detention Pond in Denver, CO that included the partially concealed Bomanite Grasscrete system that uses the Molded Pulp Formers. Stream Design met with the contractor early on to discuss some of the ideas to create more beautiful and functional drop structures to help not only enhance the storm water design and erosion control, but also to bring extra value to the neighborhood. Collectively they came up with concrete finishes that tie together nicely in a tiered design and encourage the flow of storm water. A combination of Grasscrete, stamped concrete, exposed aggregate and stained concrete, was the answer to the design decision.

By utilizing Bomanite Grasscrete, the project incorporated a pervious concrete element to the paving. Grasscrete is a continuously reinforced monolithic cast-in-place concrete solution that allows water to flow through and plants to grow within the voids. The Grasscrete was filled with a variety of different plants to blend with the adjacent planted areas syncing together the beauty of concrete and landscaping. By creating voids within a monolithic, continuously reinforced, cast-in-place concrete slab, plants have the opportunity to thrive within concrete. These voids also allow water to penetrate the slab, providing a sustainable yet durable solution for pervious pavement and storm water management. The partially grassed Grasscrete System is robust enough to withstand the Colorado winters and additional water flow while creating that feel good factor of greenspace.

The project now safely directs storm water into the detention pond while improving the water quality and aesthetics for the surrounding neighborhood. By incorporating different concrete finishes but utilizing uncolored concrete as the base of all of the paving, cost effective yet decorative concrete was provided for the City and County of Denver Public Works project.

Estate Chooses Bomanite Toppings Systems and Bomanite Grasscrete for Desired Architectural Concrete Surfaces

The owners of this grand estate in Essex County, Massachusetts installed several Bomanite systems throughout their property. The estate contains an indoor swimming pool, BBQ house, several patios and courtyards, a Barn and two garages, plus a full indoor basketball court that doubles as a Hockey Rink.

Bomanite Licensee, Premier Concrete Construction, LLC was contacted by the owner to provide a solution to a badly poured concrete garage foundation. Premier Concrete Construction remedied the garage issue, and then installed the Bomanite Broadcast Flake Toppings System in a salt and pepper finish for two separate garage units combining a total of approx. 2,700 sq. ft.

The homeowner wanted a durable flooring surface for luxury as well as off-road vehicles. Bomanite Broadcast Flake floors are multi-colored flakes encapsulated in high performance, two-component primer, body and top coats that give an architectural design and at the same time create a protective flooring system for long term use wear and tear. The Bomanite Broadcast Flake System utilizes Bomanite Florspartic 100 to create a highly durable, low maintenance surface and provides superior chemical resistance including gasoline, oil and de-icing salts.

The Bomanite Broadcast Flake System contains zero VOC’s and is a fast track flooring system that can be applied over prepared concrete and suitable cementitious toppings to form a seamless surface ideal for residential and light commercial applications such as garage floors, basements, indoor recreational facilities, schools and light manufacturing.

Various graphic designs or patterns, such as logos, family crests, homeowners’ initials, favorite sporting team emblems may be incorporated into a Bomanite Broadcast Flake System. Flake color blends are available in several sizes and custom flake colors such as metallic and fluorescent shades, glow in the dark and silver sparkle deliver unlimited creativity.

After working with Premier Concrete on the garage project and reviewing additional needs, the homeowner acquired Premier Concrete’s services for a Bomanite Pervious Concrete System. The homeowner wanted a pervious cobblestone driveway for the tradesmen estate entrance. The driveway needed to reflect the exterior design of the home and be able to handle storm water runoff.

Bomanite Grasscrete is the green alternative to standard concrete surfaces providing a variety of landscape solutions while maintaining a sustainable green product design used for emergency access lanes, delivery access routes, overflow parking areas, and for intermittent drainage channels that help prevent erosion.

Grasscrete has been used as an exposed utilitarian product for functional applications and as a concealed system with vegetation such as grass or native ground cover installed over the concrete allowing consumers to mitigate drainage issues while maintaining strong structural integrity for some of the heaviest vehicles to operate unencumbered. The Partially Concealed Grasscrete System provides the differential spacing you see with cobblestones giving the homeowner the look desired.

The Grasscrete single-use molded pulp formers were shaped and laid on the sub grade at approx. 1,300 sq. ft. to create the access for the service vehicles. Concrete was poured and placed over the formers and then voids were opened after the concrete hardened, allowing for grass to be planted.  Grasscrete offers the ability to provide year-round access for a variety of applications requiring structural paving surfaces without compromising the aesthetics of the exterior landscaping.

Premier Concrete Construction received Silver Awards for both the Best Bomanite Grasscrete Project and Best Bomanite Toppings Project.

Grasscrete Provides Access for Fire Trucks and Emergency Vehicles for Office Complexes

The office complexes at 16845 Von Karman Ave, Irvine California received an emergency vehicle access area that uses the Bomanite Grasscrete System. Bomanite Licensed contractor, T.B. Penick & Sons, Inc. worked with Wolcott Architecture to select the sustainable pervious concrete system that would work best with the intended use for the commercial development property.

The Partially Concealed Grasscrete System is engineered to provide long-term durability, low maintenance and structural strength. Access around or to buildings for fire trucks or other emergency vehicles are typically concealed with grass and defined with curbs, bollards or landscaping to complement the design of the structures and walkways. The Partially concealed Grasscrete emergency fire truck lane creates a walkway between buildings providing greenspace for employees.

Grasscrete, pervious concrete, constructed with one time use formers is time proven. Because of its structural integrity and continuous reinforcing, Grasscrete is not subject to the differential settlement that can occur with precast blocks and thin plastic products. The combination of concrete, steel and aggregate interlock ensures that Grasscrete can bear isolated loads; such as downriggers placed in an emergency situation with no support blocks. The robustness of the system minimizes the potential for failure during critical use.

The sustainable Grasscrete Molded Pulp Former System, used for the office complex project, has been engineered and field proven to bear the continuous weight of up to 114,000 pound vehicles along with such customized applications as military tank use or light speed rail track access– even when the sub-base becomes saturated making this ideal for this Emergency Access area.

An Artist Studio Utilizes Grasscrete to Manage Stormwater Runoff and Vehicle Accessibility

The residential backyard space, adjacent to an Artists/Musicians studio located in Massachusetts, required an access area to accommodate large delivery vehicles. More importantly, it required a permanent solution for stormwater management and yet still maintain landscape aesthetics necessary to help nurture the creative minds of the occupants.

Bomanite Licensee, Premier Concrete Construction worked with the homeowner in planning out the space for the Bomanite Pervious Concrete Grasscrete System. Grasscrete not only augmented the landscape architecture by handling the stormwater runoff but added benefit of a very long lifespan. Grasscrete has been a Bomanite System for over 40 years with installations throughout North America in all climate types. Grasscrete can handle the harsh New England winters and has zero potential for freeze-thaw or clogging issues. The Bomanite Grasscrete Molded Pulp Former System has been engineered to provide long-term durability, low maintenance and structural strength.

The backyard project incorporated 3,000 square feet of the Grasscrete System. A subbase was prepped to facilitate stormwater management via proper drainage and to create the outer forms of the project. Next, the Molded Pulp Formers were placed with rebar for continual reinforcement. The concrete then poured, leveled, broom finished, and allowed to dry. Voids were created to put the final finishing touches on the entire project. At the time of installation, the owner was contemplating having half of the Grasscrete fully Concealed and the half closer to the building Partially Concealed.

Grasscrete can be used as an exposed utilitarian product for functional applications or as a concealed system with vegetation such as grass or native ground cover installed over the concrete. This system allows you to mitigate drainage issues while maintaining strong structural integrity that allows for some of the heaviest vehicles to operate unencumbered. A perfect solution for this Artist Studio space.

Premier Concrete Construction, LLC won the 2018 Bomanite Gold Award for Best Grasscrete Project.

 

 

Hope Fellowship Completes Third Campus Renovation with Bomanite Polished Concrete and Pervious Systems

Bomanite Licensee, Texas Bomanite has worked with Hope Fellowship Church in Frisco, Texas for several years in different construction phases throughout the main areas of the building. Mycon General Contractors brought in Texas Bomanite for several architectural concrete applications that needed updating at the Frisco campus. Working with Small Architects, and Mycon, Texas Bomanite installed Bomanite polished colored concrete for the floors of the lobbies, stairs, hallways, auditorium and sanctuaries and upgraded the church parking lot to a pervious Grasscrete stone filled system to accommodate the need for pervious requirements and stormwater management.

Hope Fellowship is a 3-campus Bible Church located in Frisco (East campus and West campus) and in McKinney, Texas with services in Prosper, TX.  The Church broke ground with the Frisco East campus in April 2017 and completed the expansion late 2018 that included renovating all of the children’s areas, adding a 1,700-seat auditorium and adding more ministries, such as Hope Students, Adventure Kidz, a recovery ministry and a marriage ministry.

The concrete finishes that were installed included 31,890 square feet of Class B exposure with Level 3 gloss Bomanite Patène Teres polished concrete flooring throughout the campus interior, along with 4,850 square feet of Patène Artectura dyed and sealed concrete and 2,820 lineal feet of joints filled with polyurea joint filler. Two custom brown dye colors were selected by the architect to create a warm, earthy and inviting feel.

The main challenge in this project was working around the schedule of the parishioners and staff who utilize both the inside and outside of the building for classes, church services, and gatherings. The church asked that the work be completed with minimal daytime disruption. This required Texas Bomanite to work overnight on numerous occasions to remain on schedule. A crew of 5 worked through the evenings to complete the Bomanite Patène Teres polished concrete system on time.

 

In addition to the interior floors, the church was required to decrease the sites overall impervious percentage and to allow for stormwater drainage. By having Texas Bomanite install 1,800 square feet of Bomanite Grasscrete pervious concrete using the biodegradable Molded Pulp Former and filling the voids with crushed stone the criteria and requirements were met.
