Master Mark Splash Block 24 in 5-Pack - Foundation Water Diverter

In this review the Master Mark Splash Block 5-pack is judged as a practical, low-cost solution for homeowners who need a simple way to divert downspout water away from foundations. The reviewer found the plastic Chevron design effective at channeling runoff and praised its durability and ease of use; for anyone looking to prevent soil erosion and reduce pooling near a home's foundation without complicated installation, this product delivers straightforward performance and value.

Key Features

• 5-Pack Chevron design: Five decorative splash blocks provide multiple downspout outlets so several vulnerable spots can be protected at once.
• Foundation protection: The downspout diverter directs heavy rainfall away from the foundation, helping reduce water pooling and potential damage.
• Soil erosion prevention: The molded splash face spreads runoff to minimize washouts and preserve surrounding soil near downspouts.
• Universal compatibility: The splash blocks are sized and shaped to work with most downspouts, making them useful across different gutter systems.
• Durable HDPE construction: Made from plastic that resists cracking, chipping and rot so the blocks hold up outdoors season after season.

Who It's For

The Master Mark splash block 5-pack is best for homeowners, renters, or property managers who need an inexpensive, no-tools way to control stormwater at several downspout locations. It suits yards with modest slopes where directing water a few feet from the foundation reduces pooling and limits soil displacement.

It is less appropriate for properties that require heavy engineered drainage, custom underground diverters, or very large roof runoff volumes; those situations need professional drainage systems rather than surface splash blocks alone.

Pros & Cons

Pros

• Effective at redirecting rainwater away from foundations when placed under downspouts.
• Durable HDPE plastic construction that resists cracking and fading.
• Simple, tool-free installation and an attractive Chevron look that blends with landscaping.

Cons

• Surface splash blocks alone may not suffice for very heavy runoff or complex drainage problems, where more robust solutions are required.
