THE GROUT LINE
strength of the mortar bond can vary
widely and can be almost zero in older
structures. Displacement of the indi-
vidual elements is thus a continuous
risk when grouting masonry, and ex-
treme care must be taken to limit inter-
nal pressure and prevent damage of the
section being injected.
Closing thoughts
Structural grouting is a much in de-
mand technology and one that many
established grouters tend to avoid. This
results in substantial opportunity for
those that master such work, and pro-
vide these services. The procedures
have been well established for many
decades, so resources are readily avail-
able. Likewise grouting materials, both
cementitious and resinous are widely
marketed especially for structural ap-
plications. With such opportunity, ev-
ery grouter should consider working in
this market.

Frederick Lionel Peckover
1921-2015
Frederick Lionel (Peck) Peckover
passed away on February 8, 2015
in his 93rd year surrounded by his
family. Lionel was a pioneer in geo-
technical engineering in Canada. He
graduated in Civil Engineering from
the University of Toronto in 1944 and
was encouraged by Dr. Robert Legget
to pursue studies in geotechnical engi-
neering which he did through a schol-
arship at Harvard where he graduated
with an S.M. Degree in 1947.
Lionel had a distinguished career in
applied geotechnical engineering.
He served with The Saint Lawrence
Seaway Authority in a senior capacity
from 1953 to 1959 where he super-
vised design and construction of the
foundations of locks, bridges and other
structures as well as the Seaway chan-
nels and dykes. He then joined Cana-
dian National Railways and became
Engineer of Geotechnical Services
with coast-to-coast responsibility and
particular emphasis on such issues as
design of railway roadbeds on soft
ground, improvement of ballast and
reduction of frost heave, and treatment
of unstable rock slopes. In 1976 he
joined Canac Consulting Group where
he carried out terrain appraisal for a
proposed high speed rail line from
Montreal to Windsor. He retired in
1984. In professional matters, Lionel
attended the 1
st
Canadian Geotechni-
cal Society Conference in Ottawa in
1947 and maintained contact with
the Society throughout his career. He
published over 40 technical papers
and discussions in publications which
included The Canadian Geotechnical
Journal and the Journal of the Ameri-
can Railway Engineering Association,
with contributions also to a number of
technical books and manuals. In 1982,
in conjunction with the Late Doug
Piteau, he received the prestigious
Award from the Geological Society of
America for the best paper in Engi-
neering Geology.
