I am looking for a calking to put in the expansion gaps of a 30 year
old concrete slab under the house.

I hope to prevent water seeping in when I hose it and hopefully stop
the ants from carrying dirt up through the joins.

I have seen several tube calking solutions but was hoping for something
more viscous that could be poured in.

A lot of the joins in the Queen street mall (Brisbane) seem to be done
with a rubbery compound that looks to be poured rather than piped.
