The Million Pound Concrete Home
The award-winning 'House
at Empyrean Ridge' in Fort Collins, CO continues to gain accolades
for its green building design. The Colorado Built Green Program awarded
this home 252 points (the average is 70) and a 5-Star Energy Star
The home features a Quad-Lock R-38 configuration and one-million
pounds of concrete was used in the walls, the floors and the roof.

Of late, the ICF industry has been abuzz with all kinds of news
- Steve Heller has accepted the position of Executive Director for the
ICFA, effective in August. Steve has a storied background in leading
many association and advocacy groups. His talents will be fully utilized
to structure the association and its members to effectively promote and
communicate the advantages of building with insulating concrete forms
across North America.
ICFA Conference & Expo
The ICFA's annual Conference and Expo is

September 24th to 26th. A contractor track has been added that will
highlight sessions hosted by some of the industry's most notable
contractors. Influential keynote addresses will be made that you won't

Value & Service Prevent Dump & Run
Customer Service should begin with the first contact and continue
through to the project's completion. This includes timely, accurate
estimates; engineering assistance; pre-construction meetings; on-time,
complete shipments; technical support and local inventory,
representation and training. When choosing an ICF system, like most
other building materials, price alone should not be the deciding factor.
For all residential builders, this has been an especially trying
year. For ICF builders, who realize the importance of value-add service
and support, choosing the right ICF company to work with is paramount.
Why is Quad-Lock seen as the industry leader for product, service and
'Value and Service' Prevents 'Dump and Run'.
Technical and Training
Controlling Concrete Pressure at First Row
We all know that the highest concrete pressure during a pour is at
the bottom of the wall, which sometimes can cause deflection in the
first row of panels. This can be especially troublesome when working off
a slab-on-grade structure, where no backfill will be added.
In order to combat this issue, Quad-Lock has introduced a new
technique in our Product Manual and our new installation video (both due
to be released before the end of the year), as follows:
- Before panels are placed into the metal track on the first row
(of any floor elevation), a bead of spray-foam adhesive is placed in
the outside corner of both tracks for a distance of about 8 to 12
feet ahead. (Apply only as much foam as you can cover in 2 to 3
minutes, as spray foam should not be allowed to "skin over")
- Panels are then pushed down into the track, forcing the foam up
into the tie slots, adhering the panel to the track.
- Continue to place foam and first row panels, applying only as
much foam as you can cover in 2 to 3 minutes, depending on ambient
The application of spray foam into the track will help the bottom
panels resist concrete pressure.
In addition to the above technique, you can further reduce pressure
on the bottom panels by keeping the slump to 5" (127mm) or less and
vibrating the steel only. Limit the first lift height to 2 rows of
panels and limit the drop of the concrete to reduce the force of impact.
A "tremmi hose" is recommended in tall-wall applications, or pouring
from the side, as recommended in the Product Manual.
Take a tip from some of us "graybeards"; controlling concrete slump
is critical and excessively high slump will cause problems
with ICFs, especially in cold weather. Order concrete at a 3" (maximum)
slump. When the concrete truck arrives, climb up and look down into the
drum while it is turning at idle speed (NOT mixing speed). If the
concrete breaks over the fins in "chunks" or exhibits cracking as it
spills over the fins, it is too dry. Add plasticizer (not
water) SPARINGLY and have the driver go to mixing speed for 30 to 40
revolutions. Now check again, repeating the process if necessary. At the
point where the concrete just begins to "flow" over the fins
without cracking, it is ready to pour your ICF job. Depending on
the plasticizing agent, you now have about 45 minutes to offload the
concrete; PLENTY of time (if you have
installed the forms right).
Remember: It's your job, your concrete and your money. The mix
should perform the way you want it to.

Old Dog, New Tricks
When Jerry Trottier, a master carpenter for years, was involved in a
serious car accident, he thought he would have to look for a new line of
work. Not so, when Jerry researched ICF and found out how easy they were
to move around the job-site, he resurrected his custom home building
Jerry's second hurdle was to find a crew to work with - his all-woman
team ramped up very quickly. For the full story,
Green Homeowners More Satisfied
A new home buyer survey finds a high rate of customer satisfaction
among those who have purchased green homes - and that 63% of buyers are
motivated by the lower operating and maintenance costs that come with
energy- and resource-efficient homes.
These homeowners say they are extremely happy with their investments,
with 85% saying they are more satisfied with their new green homes than
with their previous, more traditionally built homes.
The research found that:
- The new green homeowner is affluent and well educated, in
his/her mid-forties and married, and also more likely to be from the
Southern or Western states. Women are also more likely to be green
- 63% report lower operating and maintenance costs as the key
motivation behind buying a green home. Additionally, nearly 50% said
they are motivated by environmental concerns and their family's
- More than 60% of those surveyed say that consumer awareness,
additional costs and the limited availability of homes are obstacles
to green homes gaining a bigger market share.
Full survey results are published in McGraw-Hill Construction
SmartMarket Report series.
