Hi,
I've just moved this to the "building" section (from "gardens"). I'm re-doing the steps through our front garden to our front door (see pic below). I've dug and set out formwork to pour concrete into for the footings of my risers. These will eventually support two bricks courses. The treads will be made of concrete slabs, with a layer of sub base below.
My question is, can I pour concrete into the formwork if there is a tiny amount of water at the bottom of these? (I'll scoop out as much as I can beforehand). What if it is forecast to rain within 24h? I can cover the footings but water will still run down into them. I appreciate that concrete is heavier than water and will displace water, but am also aware of the risk of diluting or washing out the cement. Thank you for any advice you're able to give.
