Downspout Extension & Drainage Specialists
Downspouts are designed to move roof runoff away from your home, but when they discharge too close to the structure or surrounding concrete, water can collect in areas where it may contribute to erosion and changing soil conditions. Olympic Concrete Lifting installs downspout extensions, including buried underground systems, to help direct water farther from vulnerable areas.
Downspout extensions can be completed as a standalone service or combined with Concrete Leveling & Polyjacking, Void Filling, and other concrete repairs when drainage is contributing to settlement around the property.
Why Downspout Drainage Matters
Your gutter system collects water from the roof and directs it through a relatively small number of downspouts. Without an effective discharge path, large amounts of runoff can repeatedly enter the same areas around your home.
Water concentrated near concrete, landscaping, or the foundation can gradually contribute to erosion, soft soil, and loss of support beneath nearby slabs.
Extending or burying downspouts helps control where that water goes. It is a targeted drainage improvement that can play an important role in protecting the conditions around your home and concrete.
What Happens When Downspouts Drain Too Close?
Benefits of Downspout Extensions
Properly extending downspouts helps control where roof runoff travels instead of allowing water to discharge immediately beside your home. Buried systems can move water farther from vulnerable areas while providing a cleaner and less intrusive finished installation.
Redirect Roof Runoff
Extensions carry water farther from the home and give runoff a more appropriate path away from vulnerable areas.
Reduce Soil Erosion
Moving concentrated water can help limit continued soil washout around concrete, landscaping, and slab edges.
Protect Nearby Concrete
Better drainage can help reduce conditions that contribute to settlement around driveways, walkways, patios, and steps.
Improve Water Management
Downspout extensions provide greater control over where roof water is discharged around the property.
Cleaner Appearance
Buried extensions keep drainage piping underground instead of leaving long sections exposed across lawns and landscaped areas.
Complements Concrete Repairs
Downspout drainage pairs naturally with Concrete Leveling & Polyjacking and Void Filling when water has contributed to settlement or lost support.
Where Can Downspout Extensions Help?
Our Downspout Extension Process
Evaluate the Drainage
We look at where existing downspouts discharge, how water moves around the property, and nearby areas that may be affected.
Plan the Route
Our team determines an appropriate path for moving roof runoff farther from the home and surrounding concrete.
Install & Bury the Extension
The downspout is extended to the planned discharge area. When appropriate, the drainage line is buried underground for a cleaner, more discreet installation.
Finish & Review
After installation, disturbed areas are restored and the system is reviewed to make sure runoff has an appropriate path away from the original discharge point.
Bury the Downspout. Improve the Drainage.
Above-ground extensions can move water away from the home, but long sections of exposed pipe may interfere with mowing, landscaping, walkways, and everyday use of the yard.
When conditions allow, Olympic Concrete Lifting can bury the downspout extension underground. This creates a cleaner finished appearance while carrying roof runoff farther from the home and nearby concrete.
The best setup depends on the property, surrounding grade, available discharge location, and existing drainage conditions.
Downspout Drainage as Part of Concrete Protection
Downspout extensions are often most useful when they are considered alongside the overall conditions affecting the concrete.
A driveway may need Driveway Lifting while nearby roof runoff is also contributing to erosion. A residential path may require Residential Walkway Lifting, while a void beneath another slab could require Void Filling.
Olympic Concrete Lifting can evaluate both the concrete and surrounding drainage conditions so the repair addresses more than just the visible settlement.
Downspout Extension FAQs
What are downspout extensions?
Downspout extensions carry roof runoff farther from the point where the gutter downspout reaches the ground, helping direct water away from vulnerable areas.
Do you bury downspout extensions?
Yes. Olympic Concrete Lifting installs buried downspout extensions when underground routing is appropriate for the property.
Why should downspouts be extended away from the home?
Moving roof runoff farther away can help reduce concentrated moisture and erosion around the home, landscaping, and nearby concrete.
Can poor downspout drainage contribute to concrete settlement?
Yes. Concentrated runoff can contribute to erosion and changing soil conditions. When support beneath concrete is affected, settlement can occur.
Will downspout extensions fix concrete that has already settled?
No. Drainage improvements do not raise an already settled slab. Existing settlement may require Concrete Leveling & Polyjacking.
Can you fill voids caused by erosion?
Yes. If empty space has developed beneath concrete, Void Filling may be used to restore support beneath the slab.
Can downspout extensions be installed with concrete lifting?
Yes. When drainage and concrete settlement are related, both can be addressed as part of the same overall project.
Do all downspout extensions need to be buried?
No. The appropriate installation depends on the property’s layout, drainage conditions, surrounding surfaces, and available discharge area.
