I'm going to make a small water feature consisting of a "pond" (about 60 cm
square and 30 cm deep) with a fountain (well, more of a dribble, so as not
to blow over the edges).
I already have a concrete base, and brick wall on two sides, was going to
build short brick walls on the other two sides.
What should I seal the bricks and cement with to prevent the water soaking
in? I'm concerned by the loss of water, and the wet bricks being frozen and
consequently damaged in the winter.
As always, thanks in advance to the people on this group.
