LEVELROCK Brand Underlayment RH Creates a Smooth Level Surface for
Granite and Hardwood Flooring Finishes

Complex specs on a
new 3,500-sq. ft. residential radiant heat floor called for granite in some
areas and hardwood flooring in others. The dilemma was how to create a smooth,
level surface that would lock radiant heat tubes in place even though the
finished flooring products - granite and hardwood - were of differing
thicknesses.
LEVELROCK Brand Floor Underlayment RH (Radiant Heat)
proved to be just what the doctor ordered. "By using LEVELROCK RH, we were able
to float the floor to different elevations," said Jeff Morrison, president and
owner of Morrison Construction Company, Senora, Calif. "LEVELROCK RH created a
level flooring surface, even though the finished floor products were of varying
thicknesses."
Morrison's five-man crew poured the LEVELROCK RH
underlayment 1¼-inch thick in the areas that were to receive granite and
1½-inch thick in the hardwood floor areas. The result was a perfectly
level floor surface throughout the home.

"It was great. The
contractor framed the floor to one level," said Morrison. "We then adjusted the
height of the pour to accept the various flooring products."
The
luxury home is being built in Los Altos Hills, an exclusive subdivision in the
Bay area peninsula south of San Francisco. The stucco split-level features
stone fireplaces and a guesthouse on the lower floor. Radiant heating was
specified for both floor levels.
Easy Pour
Despite the
complexities of the two-level floor surface, the installation went quickly and
easily. Fielding a five-man crew, Morrison Construction completed the entire
3,500-sq.-ft. pour -- 160 bags of LEVELROCK underlayment -- in only one day.
Alternative Energy, a company specializing in Radian Floor Heating
for over 20 years, designed and installed the hydronic system. The underlayment
was poured over the tubing, providing a thermal mass substrate which adds
increased efficiency to the heating system.
"Even though we had to
float the floor to different elevations and pour to different thicknesses,"
Morrison said, "we were still able to install the radiant heat underlayment in
only one day… with no muss, fuss or complications."

Strength Characteristics

In addition,
Morrison Construction was extremely pleased with the superior strength of the
LEVELROCK underlayment. It is formulated to provide minimum compressive
strengths of 2,500 psi. "We were able to get an average compressive strength of
2,683 psi," Morrison said. "That's an excellent reading."
LEVELROCK
RH underlayment also proved to be ideal for locking the radiant heat tubes in
place during construction. The non-shrinking nature of the underlayment
prevents noise and tube chafing. And its special formulation prevents damage
and breakage that is often associated with the high temperature of radiant heat
flooring.
