Mosolut Heavy 103R – heavy-duty permeable ground grid

Mosolut Heavy 103R is the solution for all situations where you need to reinforce a surface without sealing it with concrete or asphalt. It forms a strong structural base while still allowing natural water movement. The result is a surface that holds its shape, does not shift, does not turn into mud, and remains permeable.

How Mosolut Heavy 103R works in real use

The grid acts as a load-bearing base structure that fixes the infill material (gravel, soil, or grass) and distributes load over a larger area. Thanks to this:

• vehicle wheels do not sink into the ground
• ruts and muddy patches do not form
• water infiltrates directly where it falls
• the surface remains stable even under repeated load

Typical difference in practice:
Without grid → damaged grass, puddles, mud
With grid → stable, dry, functional surface

Real-life application examples

• Residential use
  Parking on lawns or driveways without concrete. You maintain greenery while gaining a solid parking surface.
• Commercial parking
  Stabilised parking areas for employees or visitors without the need for drainage systems.
• Industrial and logistics areas
  Handling areas where trolleys or light machinery operate – the grid stabilises the ground and extends its lifespan.
• Temporary surfaces (events, construction)
  Temporary parking or access roads that can be removed without damaging the terrain.
• Slopes and embankments
  Stabilisation of slopes, ditches, or retention basins – protection against erosion.
• Grass reinforcement (eco grid effect)
  Allows grass to grow through the structure, keeping a natural green appearance while maintaining load capacity.

Infill options depending on use

• crushed stone / gravel → maximum stability and drainage
• fine aggregate → compact and aesthetic surface
• soil + grass → natural look with preserved greenery

Key benefits

• Strength without concrete
  A stable surface without sealing the ground.
• Natural water infiltration
  No puddles, no drainage systems required – water stays on site.
• Mud prevention
  Maintains ground structure even in wet conditions.
• High load capacity
  Suitable for cars, vans, and standard machinery.
• Eco-friendly solution
  Supports natural water cycles and preserves landscape appearance.
• Versatile use
  Can be used as a final surface or as part of base layers.

Installation principle

Individual grids connect via locks into one stable surface that:

• holds infill material in place
• distributes load
• allows water infiltration
• protects the ground from degradation

The result is a long-term solution without frequent repairs.

Comparison with common solutions

Practical tip:
Combine Mosolut Heavy 103R grids with Mosolut panels (132, 123) to create multi-functional areas – e.g. parking + reinforced handling zones.
