Yes, you can pour concrete if it rained the day before, but you’ll need to drain the construction site to ensure there isn’t standing water where your slab will sit. You might need to manually remove any puddles and set up drainage on your site to dry it before pouring. Moist soil won’t be an issue, but standing water will throw off your concrete mix ratios. Additionally, ensure there isn’t more rain expected in the near future before you pour.

Drying concrete faster after rain is tricky because you’d need to increase the temperature or airflow over your slab, both of which are challenging to do outdoors. It can help to remove water from your concrete quickly, though, as the faster you remove rain from the surface, the lower the risk of the water affecting the ratio of your concrete mix. Use squeegees or mops to remove water, and consider covering your slab with a tarp to protect it from future rainfall.

Underlayment is the barrier between the concrete floor and the hardwood flooring. Adding this barrier is a vital step when installing hardwood over concrete, and it’s essential for protecting the wood from moisture coming from the concrete. Some adhesives are also manufactured to contain a moisture barrier that can protect hardwood from moisture, even if it’s glued directly to the concrete.

Pervious concrete can last from 20 to 40 years when properly mixed, poured, and maintained. Pervious concrete requires yearly maintenance to remove debris from the surface that can block the voids and interfere with effective drainage, but properly maintained pervious concrete can last as long as traditional concrete.
