Lauxes Grates Midnight Storm Water NeXT Generation 128 is an extruded aluminium stormwater grate engineered for high-traffic residential driveways and corrosive coastal environments. This 128mm wide profile supports vehicle loads up to 10.2 tonnes and features a 19mm deep top tray specifically compatible with 13mm tiles or pavers for a flush architectural finish.
The UV-stabilised Midnight Black surface ensures 25 years of colour integrity, while the non-ferrous construction provides a lifetime rustproof warranty against tea-staining or oxidation. Driveway contractors should maintain a 1-2mm/m fall and use a non-ferrous metal blade for onsite cutting to maintain the structural integrity and corrosion resistance of the anodised profile.
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.

Applying Lauxes Grates NeXT Generation 128: Enhanced Protocols & Best Practices
-
1. Surface & Channel Preparation
Inspect the existing plastic stormwater channel for cracks, obstructions, or deformation. Remove debris and ensure the surface is clean, dry, and level before installation.
Pro Tip: Wipe the surface with Adheseal Surface Prep to remove oils or residues for a precise fit and improved adhesion of sealant beads if applied. -
2. Cutting to Custom Length
Measure and mark desired length using a fine-tip marker. Secure the grate before cutting to avoid vibration. Use a drop saw with a non-ferrous metal blade for clean, burr-free edges.
Pro Tip: Allow a 2 mm expansion gap per metre of length to accommodate temperature-based expansion and contraction. -
3. Installation & Alignment
Fit the top grate into the existing stormwater channel, ensuring even contact along its full length. Confirm tile or paver height aligns with the 19 mm top profile for seamless water flow.
Pro Tip: Use a level to check alignment and flow direction—slight fall of 1–2 mm/m ensures optimal drainage.
Product limitations
- Not for: Continuous exposure to highly acidic or corrosive chemical processing environments. Aluminium may degrade over time in such conditions.
- Avoid: Using abrasive cutting discs designed for steel. These can damage the anodised surface, leading to premature dulling and compromising the finish.
- Requires: Installation with proper slope and flow direction. Incorrect alignment can lead to backflow, water pooling, and ineffective drainage.
Safety and handling
Personal protective equipment
Use cut-resistant gloves and safety eyewear when handling or cutting aluminium profiles to prevent burr injuries.
Ventilation
Perform cutting operations in a well-ventilated area to prevent aluminium dust accumulation. Use dust extraction equipment where possible.
First aid
- Eyes: Flush with clean water for at least 15 minutes. Seek medical advice if irritation persists.
- Skin: Clean with mild soap and water. Cover any cuts or abrasions immediately.
- Inhaled: Move to fresh air. Seek medical attention if breathing difficulty occurs.
- Swallowed: Rinse mouth. Do not induce vomiting. Obtain medical assistance promptly.
Storage and disposal
Store in a dry, protected environment to prevent surface damage. Aluminium itself is non-combustible; however, fine dust can pose an ignition risk. Keep away from open flames during cutting or grinding operations.
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.
