## Long description

Prosperplast Mosaic black IAK401-S411 is a plastic permeable walkway and drainage grid engineered for outdoor surfaces such as paths, terraces and green areas. Its openwork lattice enables effective water infiltration to reduce surface pooling while providing a stable walking surface. The grid is lightweight yet durable, allowing easy installation as either a temporary or permanent solution for stabilising gravel, improving lawn access and enhancing permeability in landscaping projects.
Advantages
The design of the Mosaic black grid combines high permeability with mechanical stability to allow foot traffic without significant sinking or displacement of aggregate. Made of weather-resistant plastic, the grid withstands outdoor conditions and resists moisture and corrosion. Its modular, interlocking format simplifies handling and installation and reduces the need for heavy tools or long curing times typical of rigid paving systems.
Suitable for
Garden and park paths
Terraces and outdoor seating areas
Gravel stabilisation and driveway reinforcement for light vehicle traffic
Lawn protection and access routes over soft ground
Temporary event flooring and permeable landscaping solutions
Key specifications
Material: weather-resistant plastic
Color: black
Structure: openwork lattice for water permeability
Application: pedestrian surfaces, gravel stabilisation, lawn reinforcement
Weight: lightweight for manual handling and modular installation
How to use
Prepare the base by clearing vegetation and levelling the surface. For improved stability, lay a compacted layer of sand or fine gravel before placing the grids. Snap or interlock the grid modules together across the area to be covered, trim modules where necessary to fit edges or obstacles, and fill openings with desired aggregate such as gravel or turf. Ensure modules are aligned and secured to maintain a continuous surface and restore any disturbed edges after filling.
Usage recommendations
For best results on soft or uneven ground, use a compacted sub-base layer and select aggregate size appropriate to the grid openings. Regularly inspect interlocks and filled material after freeze–thaw cycles or heavy loads to maintain performance and drainage.
