The NeXT Generation version of the 128mm stormwater grate: same 10.2 tonne driveway rating, 13mm tile tray, and lifetime rustproof build, with the NeXT Generation channel system behind it.
The 19mm deep top tray suits 13mm tiles or pavers for a flush finish, the Midnight Black surface is UV-stabilised with a 25-year colour guarantee, and the non-ferrous aluminium will not tea-stain in coastal air.
Set the falls at 1-2mm per metre and cut with a non-ferrous blade on site to keep the anodised edge clean.
Frequently asked questions
Can this NeXT Generation 128 grate handle vehicle traffic?
Yes, the NeXT Generation 128 is rated for loads up to 10.2 tonnes. This makes it suitable for driveways and other trafficable areas where structural integrity under vehicle weight is critical.
What is the maximum tile thickness this grate supports?
The top tray accommodates tiles or pavers up to 13 mm thick. This ensures compatibility with common outdoor tiling and paving systems without extensive modification.
Can I cut this aluminium grate to size on site?
Yes, the aluminium extrusion can be safely cut on site. Use a mitre or drop saw with a fine-tooth blade for a clean cut, and deburr edges to prevent injury.
Substrate guide
Proper surface preparation is crucial for a secure and functional drainage system. This guide covers common substrates for NeXT Generation 128 installation.
Concrete channels
Surface prep: Ensure concrete channels are fully cured, clean, and dry. Remove laitance, oils, dust, and loose debris. The surface must be level to ensure a flush grate fit.
Primer: Not required. The aluminium grate installs mechanically into the channel. Primer is only necessary if a sealant is used for waterproofing the junction.
Plastic stormwater channels
Surface prep: Wipe channel edges with Adheseal Surface Prep or isopropyl alcohol to remove any manufacturing residues or grit. Verify fitment tabs are intact.
Primer: Not required. This grate acts as a mechanical replacement top. If sealing against tile edges or preventing uplift, use Adheseal MS Construction Sealant without primer.
Tiled or paved surrounds
Surface prep: Dry-fit tiles or pavers first to ensure correct alignment. This grate accommodates surfaces up to 13 mm thick. Ensure the interface provides seamless water flow without a lip.
Primer: Optional. If sealing between tiles and grate edges, apply Adheseal Non-Staining Tile Silicone directly for a flexible, waterproof joint. No primer is required for the silicone.
