A splash block sits beneath a gutter downspout to guide rainwater away from your home in a controlled path. Instead of water digging a trench or pooling at the base of your wall, the block spreads and redirects the flow onto the yard or a landscaping area.

• Helps protect foundations: By moving runoff away, it can reduce soil saturation near the house.
• Controls erosion: Limits washouts in mulch and garden beds.
• Cuts splash-back: Less muddy water splattering onto siding.

You’ll find options in plastic, rubber, composite, concrete, and decorative metal styles. Choose a style and size that fits your downspout area and complements your yard.

Costs can vary based on what the splash block is made of, how big it is, and whether it’s decorative or basic. Multipacks and kits may change the per‑piece value, too.

• Material: Plastic is typically lightweight; rubber and concrete tend to be heavier.
• Size and weight: Larger or heavier pieces often cost more to ship.
• Design: Decorative shapes or cast details usually add to the price.
• Pack size: Singles vs. 2‑packs or more.
• Bundled features: Some include extensions or drainage components.

On our site, you can filter by material, length, and customer ratings, compare pack sizes, and choose store pickup or delivery to help manage total spend.

If you’d like to make one, there are simple approaches, but results can vary with materials and weather. Focus on stability and safe water direction.

1. Concrete mold: Build a small form, pour concrete, and shape a gentle channel. Wear gloves and eye protection when mixing and allow proper curing.
2. Paver channel: Set flat pavers on compacted base with a slight slope away from the house. Edge with small stones to guide flow.
3. Stone tray: Create a shallow “tray” with flat stones over gravel to disperse water.

Aim runoff away from foundations and walkways, keep the surface stable and level, and check local guidelines for water discharge. Prefabricated options offer quick, consistent results if you prefer ready-to-use pieces.

They manage the surge of water coming out of a downspout by spreading and directing it away from the base of your home. This can help reduce erosion, minimize puddles near the wall, and limit muddy splash on siding.

• Grade matters: For best performance, the ground should slope away from the house.
• Stable base: Set on compacted soil or gravel so it doesn’t shift.
• Alignment: Center under the downspout outlet so water hits the block, not soil.
• Pairing: In heavy rain, combining a block with a downspout extension or a yard drainage feature can move water farther.
• Maintenance: Clear leaves and sediment so water flows freely.

Position it directly under the downspout outlet with the open end pointing away from your home. The goal is to carry water toward lawn or landscaped areas that can absorb runoff.

1. Start at the outlet: Slide the block’s top lip beneath the downspout so water lands on it.
2. Point it downhill: Aim toward a spot that slopes away from the foundation.
3. Stabilize the base: Use compacted soil, paver, or gravel to keep it level.
4. Direct the flow: Avoid sending water onto walkways or neighboring properties.
5. Check and adjust: After a rainfall, confirm water is moving as intended and clear debris.
