Small Bridge Problem

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Dear Paul,
Thank you for this revelation.
I did not know that concrete swells so much when surrounded
by soil. Is it because of lack of air?

Gregory,
You can use regular concrete for injection, you do not need a special "swel=
ling liquid." Be careful during injection - it is relatively easy to over i=
nject and raise the structure higher than desired.
