ϐigure out what you really need, but I
always tell everybody to be prepared,
because you may not like what you see."
Those comments are echoed
by Michael Tharpe, national sales
manager at Rainier Industries Ltd. in
Tukwila, Wash., who contributed to the
development of the ballasting study and
is currently chair of the TRD.
"The most common cause of ballast
failing is simple," says Tharpe. "It's not
using enough ballast. And a tent will not
remain erect unless it's secured to the
ground on which it sits. That's the cold
hard fact of it."
Besides using the Ballasting Tool,
Tharpe says it's important to have and
use the manufacturer's installation
instructions and any pertinent
engineering documents that reϐlect the
loads placed on the tent. "What you

need for ballast in normal conditions
with no weather is important," he says.
"But you need to use the engineering
information to tell you the wind load
criteria; you have to go up to the point
where the tent will tip, or wants to tip."
And there's nothing wrong with erring
on the heavy side, says Bains. "I like to
see an overweighted tent," she says. "You
feel good in an overweighted tent."
"It is costly to move all this concrete
weight around," concludes Eisenstein.
"It costs more than water barrels. And to
move 700-pound blocks you need some
pretty strong guys. But it's safer. I can
sleep at night. My insurance claims are
down and wind isn't getting underneath
our tents and blowing them away."
