Underground Downspout Extensions & Routing in Des Moines

Your gutters do a great job catching rainwater from your roof, but if your downspouts are dumping hundreds of gallons of water right next to your foundation, you are asking for trouble. Above-ground plastic accordion tubes are an eyesore, a trip hazard, a nightmare to mow around, and they easily get crushed or blow away.

HCS Concrete specializes in burying downspout extensions. We connect your existing gutters to durable, underground PVC or heavy-duty corrugated piping, routing it safely to a pop-up emitter or discharge point far away from your house, driveway, and patios.

Our Downspout Routing Process:

1. Sizing & Trenching: We calculate the volume of roof runoff and trench a precisely sloped path away from your foundation.

2. Secure Connections: We cleanly adapt your metal downspouts to thick, underground piping, ensuring a tight seal that won't leak at the foundation wall.

3. Discharge Installation: We install flush-mounted pop-up emitters in your lawn or route the pipe directly to a curb, creek, or storm drain, then backfill the yard.

Frequently Asked Questions:

• Will buried downspouts freeze and burst in the winter? When properly pitched by our team, all the water drains out completely by gravity, leaving the pipe empty so there is nothing inside to freeze and burst.

• Do you use corrugated pipe or solid PVC? We offer both! Solid PVC is incredibly durable and easy to clean out, while heavy-duty corrugated is highly flexible for navigating tree roots and complex landscaping.
