Water In Deck Footing Holes
If you have a high water table or it has just rained, you may find that your footing holes have flooded with water. This is not usually a problem. Water can be bailed or pumped out, and the soil at the base of the hole can be compacted. The concrete you pour into the hole will displace the water, this is called wet-placing concrete. Big Foot form tubes can also be installed to keep the water out of your concrete pour. The bell shape of the footing form will help keep the footing in place and prevent it from floating up to the surface. Once the footing is poured, you may want to backfill some gravel around the footing to promote drainage. Concrete poured in wet conditions will actually have more strength. The slower the concrete cures, the stronger it will set.
