Preparing Foundation Holes in Saturated Soil
When the water table is high or after heavy rains, it's common for the holes for your composite deck to fill with water. This is not a major obstacle to installing your composite deck. Here's how to effectively manage this situation in the context of patio Québec and outdoor living spaces.
Managing Water and Compaction
Before pouring concrete, you need to:
- Drain the water: Using a pump or a bucket, remove the accumulated water.
- Compact the soil: Ensure the bottom of the hole is well-compacted to guarantee stability.
Wet-Placing Concrete
Wet-placing concrete involves pouring concrete directly into the water present in the hole. The concrete will gradually displace the water, ensuring a solid footing for your structure. In wet conditions, concrete tends to cure more slowly, which strengthens its final resistance.
"The slower the cure, the more the concrete develops its full strength, essential for supporting the loads of a quality composite deck."
Using Big Foot Footings
To prevent water infiltration during pouring, Big Foot footings are ideal. Their bell shape prevents flotation and keeps the concrete in place.
Backfill and Drainage
After pouring, add gravel around the foundation to facilitate drainage and prevent water accumulation under your composite deck.
