How one heavy-duty permeable grid paver solved erosion and elevated the look of a hillside patio.
The short answer: TERRALOCK PAVER is a permeable concrete grid paver used to control erosion on slopes, driveways, and walkways. Its interlocking cells lock soil in place and let water drain straight through, preventing the runoff that washes hillsides away. Each unit is made from 5000 psi fiber-reinforced concrete, covers 1.56 sq. ft., and weighs 39 lbs.
Every great outdoor space has a problem lurking beneath the surface — and for this backyard, it was water. Set on a slope behind a stone retaining wall, the patio area was losing ground to runoff and erosion with every rainfall. The homeowners needed a solution that could stand up to the elements without sacrificing curb appeal. Enter the TERRALOCK PAVER.
As the photos show, the crew laid the interlocking grids in a clean, flowing pattern across the graded slope — fitting them snugly against boulders, garden beds, and the base of the retaining wall. Because each grid locks into the next, the field went down fast and stayed put, creating a stable, permeable surface built to channel water straight into the ground instead of washing soil downhill.
Which Paver Is Best for Slope Erosion Control?
TERRALOCK PAVER is a heavy-duty interlocking permeable grid paver system — engineered for parking areas, walkways, and erosion control alike. Once filled with grass or gravel, the open-cell grids all but disappear into the landscape, delivering the kind of high-end, finished aesthetic that turns a functional fix into a design feature. This is erosion control that looks like it belongs.

Frequently Asked Questions
- How do you stop erosion on a backyard slope
- Install a permeable grid paver system across the graded slope. TERRALOCK PAVER grids interlock to hold soil in place while their open cells let rainwater drain into the ground, eliminating the surface runoff that erodes hillsides. Filling the cells with gravel or grass adds further stability.
- What are permeable pavers and how do they work?
- Permeable pavers are paving units with open cells or gaps that allow water to pass through the surface and soak into the soil below, instead of running off. This reduces flooding, erosion, and drainage problems while still providing a firm, load-bearing surface for foot or vehicle traffic.
- Can grass grow through TERRALOCK PAVER?
- Yes. The open-cell design is made for it. After the grids are laid, they’re topped with loam and grass seed; the grass grows up through the cells for a green, seamless finish while the concrete grid carries the load and holds the soil in place.
- Where can TERRALOCK PAVER be used
- TERRALOCK PAVER is versatile enough for grass or gravel parking areas, driveways, walkways, and slope erosion control across residential, commercial, and municipal projects.
- How much does one TERRALOCK PAVER cover and weigh?
- Each unit measures 15″ × 15″ × 4″, covers 1.56 square feet, and weighs 39 lbs. It’s molded from durable 5000 psi fiber-reinforced concrete.
