Drainage Holes Explained: Why they Matter

Wondering what drainage holes are and why they matter in a pool demolition project? If you’re filling in your pool and asking what happens to rainwater after demolition, drainage holes are the answer. These specifically cut openings in the base of your old pool allow water to move naturally through the ground. Without drainage holes, water could collect and cause damage to the soil and structures around it. For homeowners choosing partial removal, drainage holes are a must for long-term peace of mind.

In a partial pool removal, we saw cut 3 to 4 drainage holes directly into the bottom of the pool shell. Each drainage hole is typically around 2 by 2 feet, but this can vary based on city codes. Drainage holes are what allow rainwater to pass freely, avoiding future problems like soil shifting or water pressure buildup. These holes make all the difference in protecting your yard after the backfill process is complete. Without proper drainage holes, you run the risk of flooding beneath your lawn.

The purpose of this step is simple but essential: to allow water to flow through, not collect. Once the holes are made, we install a mesh layer to stabilize the opening. Then, we add gravel for filtration and drainage, compacting everything tightly. This creates a safe, breathable space for rainwater to pass through the ground over time. In just one day, the installation helps prevent years of potential issues. It’s a vital step for a smooth and successful pool demolition.

Drainage Holes After Pool Demolition: Keep Your Yard Safe and Dry

Keep in mind, this step is only part of a partial pool demolition—not full removals. When the entire pool shell is taken out, added drainage measures aren’t necessary because no structure is left underground. But if the shell stays, allowing water to escape becomes non-negotiable. Without a way for water to exit, the leftover shell would act like a basin. So if you’re going partial, make sure your contractor understands how critical proper drainage is for both code compliance and your yard’s long-term health.
