NOBOROKKA is designed for use on slopes with inclinations between 25° and 45°.
The system is secured by driving metal stakes into the ground with a hammer.

NOBOROKKA is not suitable for installation in the following ground conditions:

• Extremely hard bedrock
• Soil containing large buried rocks
• Sandy or loose ground where stakes cannot achieve sufficient hold

Installation may be possible on the following surfaces:

• Concrete or other hard surfaces, provided pre-drilling is available

To ensure proper installation, we strongly recommend confirming your ground conditions in advance using our Fit Check.

Each step is typically spaced approximately 16 inches (40 cm) apart, aligning with a natural walking stride.

A standard 6-step set covers approximately:
→ 8.2 ft (2.5 m) of slope

For steeper slopes, we recommend reducing the spacing between steps to provide enhanced stability and a more secure footing.

Example calculations:

For a 32.8 ft (10 m) slope:
32.8 ÷ 8.2 = 4 sets → 24 steps total

For a 9.8 ft (3 m) slope:
9.8 ÷ 8.2 ≈ 1.2 sets
→ A combination of one 6-step set and one 2-step set is recommended

We recommend measuring the full length of your slope and adjusting the number of sets as needed based on the slope’s steepness.

NOBOROKKA is designed to support users weighing up to approximately 330 lbs (150 kg), including gear.

For safe and stable use:

• At least 80% of each step should be supported by direct ground contact
• If the soil shifts over time, such as after heavy rain, the stakes can simply be re-driven to restore stability

Yes.
Multiple units can be connected side by side using standard M10 hex bolts to create a wider walking surface.

• Standard width: 20 inches (50 cm)
• Expanded width: up to 40 inches (100 cm)

This configuration is ideal for side-by-side use and areas with higher foot traffic.

No special tools are required for installation.
For best results, we recommend having the following on hand:

• Shovel or rake for light ground leveling
• Hammer, preferably a wooden or rubber mallet
• Work gloves for added safety during installation

NOBOROKKA is designed as a DIY installation system and requires only minimal site preparation.

Installation typically involves:

• Light ground preparation
• Hammering the stakes into place

No heavy machinery, professional construction, or concrete work is required.

To help prevent weed growth, we recommend installing NOBOROKKA over weed barrier landscape fabric.

Recommended installation steps:

1. Clear any existing vegetation
2. Lay the weed barrier fabric
3. Install NOBOROKKA on top

This approach not only helps suppress weeds, but also makes ongoing maintenance, such as mowing and general upkeep, much easier.

No.
NOBOROKKA is made from a high-quality composite of recycled polypropylene (PP) and bamboo, offering long-term durability in outdoor environments.

Key benefits include:

• Will not rot like wood
• Resists moisture and moss buildup
• Maintains grip and safety over time

Under typical residential use and in moderate climates, NOBOROKKA is designed to last 15 years or more, depending on environmental conditions and usage.

For slopes exposed to heavy rain or erosion, additional reinforcement can be added to improve stability.

We recommend:
→ Connecting the steps vertically using coated wire rope (approximately 3/32 in / 2.5 mm)

This helps reduce the risk of movement or washout in challenging conditions.
