Terra cotta usually a light weight facing material hanging
on the side of the building. Oringally there was a lot of
supporting material in the form of masonry fill behind the
facing bricks, but today don't like to hang addition weights on
these structures. The GRC pieces will weigh less than the
orignal terra cotta.

Glass fibre used is 5 per cent by weight.’ GRC was
developed by Pilkinton and is a patented process which
came to Canada in the mid 70s; manufacturers licenced under

Strict control. US distributor is Cem-fil in Nashville, Tenn.

The project is worth $160,000 to Supercrete; total
project is $1.8 million, and involves major interior alterations
and replacement of glass brick windows.

The GRC form work took a substantial amount of time

and_they spent eight weeks on engineering details. Had to go

to the site and take a lot of measurements. Took about 4 months
in total to produce all the forms. pp

The glass fibres used cost about $2.75 per pound,
but in total cost the GRC is comparble to normal precast.
This product really stands out ina molding application, and is
able to capture very fine details. 0

"I would think that in more remote areas, like
northern Manitoba, we could see a much more economical movement
of/gigcast building facade material than normal precast.”

Could use GRC because it's lighter, and transportation costs

are important in the north. This would be a primary market.
