...So you started to pour the slab, all though the
weathermen are saying there is an 80% chance for rain
that day, and as a concrete contractor you gotta do
your job that day.Living in Vancouver, BC.this could
happen to you often, mainly in the winter, which is
rainy, and mild.
And guess what... while working wouldn't you know?!It
has started to rain.Well if you're smart, you already
have enough poly with you to cover the whole slab,
or have made arraignments to deal with it beforehand .
In case if you didn't know, as soon as water hits the
concrete,you start loosing time, and the chances of
getting aquality finish deteriorating by every drop
of rain falling on your concrete.
So my advise to you is to cover it as soon as possible
to control the damage to a minimum, unless you're into
much concrete repair..., or don't take a chance,
unless it's an absolute must to get the job done.
You can still make the cuts, edges, and broom a
sidewalk with your college lifting up the poly, while
you working underneath, but with a patio, or bigger
driveway, it gets tricky.
Let suppose you're pouring a big slab on grade in the
rain, and it has to be machine finished. there is no
way covering a large surface like that.the best next
thing is for damage control is to wait until is hard
enough to machine without mixing in the water, than
sweep trowel it as you go.
As an experienced concrete contractor,and a cement
finisher I could go on about details for a while...
