part of concrete’s strength is in the thickness of the slab. Grasscrete formers are designed for a 5 1/2-inch thick concrete pan.
One of the most unique features of Bomanite’s formers
are that they are made of recycled paper pulp and are 100
percent biodegradable. Rather than being removed after the
concrete is cured, the pulp formers slowly begin to dissolve as
soon as the pour starts. Despite being a durable pavement,
the Grasscrete system results in 37. 5 percent surface and effective void, meaning almost a third of the entire surface is
open and can be planted. This allows the vegetation to truly
blanket the concrete. In the case of the NREL project, Colorado Hardscapes added an integral color to the concrete mix,
making the structure largely disappear altogether.
Due to Grasscrete’s long-term durability, high compressive
strength, and pleasing aesthetic possibilities, Colorado Hardscapes and other licensed Bomanite contractors across the
country are pouring it on a wide range of projects. Because
it produces a hard, drivable surface capable of supporting the
weight of a 114,000-pound fire apparatus, Grasscrete is often
used where emergency vehicle access is a code requirement
but the owner desires a planted lawn. Overflow and industrial
parking lots where surface drainage can be beneficial, as well
as roadway shoulders and embankments are all opportunities
for engineers to consider this application.
“Colorado Hardscapes is proud to be a 34-year Bomanite li-
censed contractor,” said Buteyn. “They bring very high brand
standards, training and technical expertise that increase our
opportunities to provide clients like NREL with unique, innova-
tive construction solutions. We’re able to add to that hands-on
craftsmanship, collaborative relationships with local architects
and general contractors, and an established quality mix that we
source from a single ready-mix supplier.” Together, Bomanite
and licensed contractors are working with clients, designers, and
builders to tackle flatwork challenges and opportunities of all
kinds from complex to simple, decorative and practical. WW

Grasscrete allows vegetation to be planted into voids, enabling the root
systems to form below the surface of the concrete.

sionals and your engineer.
It pays to use high-quality products that are exceptionally
durable, even in harsh conditions, and designed to prevent
future pipe damage. For example, Krausz products, such as
the HYMAX, allow for repairs to maintain a flexible connection to prevent damage from post-installation ground shifts
and temperature changes, protecting your investment over
the long term.
Remember, there’s a difference between the lowest responsible bidder and the lowest bidder. The lowest bidder will
sometimes leave things out of the bid and come back with a
change order — which can dramatically increase the budget.
When it comes to using the right contractor and parts, do
your homework and get references to avoid surprises.
Have a realistic schedule. Make sure that your work sched-
ule is fair to all of those involved. Customers will expect a
project that adheres to a schedule that has the least effect
on them. Your contractor will want a tight schedule so they
can continue to their next job and avoid penalties for not
meeting the scheduled completion date. Be realistic and
stay in close communication with all those involved in the
project, especially when plans change during construction.
If all goes well, there should be no surprises. Contractors
and engineers should walk away happy, and the utility and
customers should have a well done project.
Determining whether to repair or replace pipe is not an
easy decision to make. It requires recording and analyzing
data and costs, and close communication between customers, engineers, contractors, inspectors and the utility. It’s hard
work but the long-term benefit of reliable service will last for
