Best Asphalt Driveway Water Diverters for Managing Runoff
The best direct asphalt driveway water diverter in this selection is the PIG Rainwater Diverter, a reusable barrier made to control runoff on smooth surfaces. For water coming from a gutter downspout before it reaches the driveway, consider a splash block instead. The options below include a modular driveway barrier, decorative plastic blocks, and rubber trays in different pack sizes.
| Product | Best For | Type |
|---|---|---|
| PIG Rainwater Diverter | Runoff across a smooth driveway | Interlocking water barrier |
| Master Mark Splash Block | Decorative downspout control | Plastic splash block |
| Sekcen 3 Pack Gray | Several downspouts or locations | Rubber splash blocks |
| Sekcen 2 Pack Brown | Smaller projects and brown landscaping | Rubber splash blocks |
| Rocky Mountain Goods | Large, no-anchor downspout block | Decorative splash block |
PIG Rainwater Diverter For Driveways
The PIG Rainwater Diverter is the most directly relevant choice for directing water on an asphalt driveway. It is a 10-foot-long barrier designed to confine and divert runoff without absorbing it. Its listed dimensions are 2.25 inches wide and 1.375 inches high.
Best for: Homeowners who need to redirect nuisance water or manage wash-down water on a smooth driveway or garage surface. Interlocking end joints let users connect sections to extend the barrier without extra parts.
Limitation: The product is described for smooth surfaces, so it may be a poor fit for rough, uneven, or heavily cracked asphalt. It redirects water rather than absorbing it.
Master Mark Decorative Splash Block
This 24-inch gray plastic splash block is intended to direct water away from a downspout and nearby foundation, lawn, or landscaping. Its chevron design adds a decorative element, while a tab can be used to anchor it. Stakes may be purchased separately.
Best for: Buyers managing gutter discharge before it runs onto an asphalt driveway, especially when appearance matters. Set it so water flows toward a suitable drainage area rather than pooling beside the pavement.
Limitation: It is a downspout splash block, not a long barrier for channeling water across a driveway. The listing does not include stakes.
Sekcen Three-Pack Gray Rubber Blocks
This three-pack is a practical option for managing runoff from multiple downspouts or placing splash blocks at several locations. The blocks are made from recycled tire rubber, and their sloped design is intended to spread water away from a foundation while reducing standing water on the trays.
Best for: Homeowners who want several rubber downspout diverters to help limit soil erosion, mud splashes, and water reaching the driveway edge.
Limitation: These trays direct water near downspouts; they are not described as interlocking driveway barriers. Check that the available area gives redirected water somewhere to go.
Sekcen Two-Pack Brown Rubber Blocks
The brown Sekcen set offers the same listed sloped-tray design as the gray three-pack, in a two-block quantity. Recycled tire rubber is specified, and the product is intended to direct downspout water away from foundations while helping reduce erosion and mud splatter.
Best for: Buyers who need fewer blocks or prefer a brown color near landscaping. Choose this over the three-pack if two downspout locations are the main concern.
Limitation: Like other splash blocks, it manages water at a downspout rather than creating a continuous runoff channel across asphalt.
Rocky Mountain Goods Large Splash Block
This large 24-inch black splash block disperses gutter water away from a downspout. Its listed features emphasize a heavy-duty design, decorative finish, and installation without an anchor.
Best for: Buyers who want a single, larger downspout diverter to protect lawn or flower beds and keep water from flowing directly toward a driveway or foundation.
Limitation: It is designed to disperse water from a gutter, not to contain or channel runoff across the driveway surface.
Buying Guide: How To Choose A Driveway Water Diverter
Do you need a barrier on the asphalt or a downspout extension?
Choose a driveway barrier when water is already flowing across the pavement and needs to be redirected along a different route. The PIG model is the direct match here: it is reusable, non-absorbent, and has interlocking ends. Choose a splash block when the water source is a gutter outlet and you want to direct discharge away from the pavement, foundation, or landscaping.
What should you check about the surface?
Surface contact matters for a loose water diverter. PIG specifies smooth surfaces, so consider whether your asphalt is level enough for the barrier to sit in place. For a splash block, plan the direction of its slope and make sure redirected runoff will not simply collect at another low point.
How many pieces do you need?
A single splash block may be enough for one downspout. Multi-packs can suit homes with several outlets or locations. For a longer driveway barrier, the PIG product’s interlocking joints allow sections to be joined. The listed product information does not specify how many sections are needed for a particular driveway.
Which material and appearance fit the site?
The listed options include plastic and recycled-rubber splash blocks, as well as a flexible-style barrier intended for smooth surfaces. Compare color and shape with the surrounding driveway and landscaping, but prioritize a clear drainage path. No diverter can correct a larger drainage problem by itself if water has nowhere to flow.
Frequently Asked Questions
What is the best type of diverter for water crossing an asphalt driveway?
A low water barrier designed for smooth surfaces is the most direct option in this list. The PIG diverter is specifically listed for driveways and can connect with additional sections.
Will a downspout splash block divert water across a driveway?
A splash block directs gutter discharge away from its downspout. It is not described as a continuous channel for carrying water across a driveway.
Can the PIG diverter absorb rainwater?
No. Its listed function is to confine and divert water without absorbing it.
Do splash blocks need to be anchored?
It depends on the product. Master Mark includes a tab for anchoring, with stakes sold separately; Rocky Mountain Goods says no anchor is needed.
How can I reduce water pooling near my driveway?
Direct runoff toward a suitable drainage area and avoid placing a diverter where water will collect. If pooling persists, assess the slope and drainage conditions around the pavement.
