30mm Domestic Grids

IBRAN-X-30 is our 30mm octagonal ground reinforcement grid: the shallowest grid in the range and, cell for cell, the strongest. The octagonal geometry distributes load across eight faces instead of four, which is what lets a 30mm section carry the same 500 tonnes per square metre as grids half again its depth.

That matters most where dig depth is the constraint. On a driveway that has to meet an existing threshold, a path alongside a building, or a project where you are working to a fixed finished level, every 10mm of grid depth is 10mm of excavation and 10mm of spoil to remove. IBRAN-X-30 gives you the load capacity without the depth.

Where it works best

• Gravel driveways and parking. The octagonal cells hold angular stone tightly and stop the migration that turns loose gravel into ruts and bare patches.
• Paths and walkways. Filled level and blinded, it gives a firm, even surface that walks well and takes a wheelbarrow or a wheelchair.
• Shed, bin and hot tub bases. A free-draining, load-spreading base that goes down in an afternoon, with no concrete and nothing to mix.
• Shallow build-ups. Anywhere the finished level is fixed and you cannot afford the depth a deeper grid needs.

How it compares to the 40mm

Both carry 500 t/m2. The difference is depth and what follows from it. IBRAN-X-30 needs less excavation, less spoil removal and fits 25% more grids on a pallet, which brings the delivered cost per square metre down on any job of size.

The 40mm IBRAN-X is the better choice for reinforced grass, where the extra depth gives the root zone room to establish under traffic. For gravel surfaces, IBRAN-O is what we would specify.

Installation

Excavate to your sub-base depth plus 30mm plus a 5-10mm blinding. Lay a woven geotextile, then compacted MOT Type 1 in layers of no more than 75mm. Blind with grit sand, screed level, push-fit the grids together and fill the cells with angular 10-20mm gravel. Add no more than 10mm over the top: anything deeper is unconfined stone and will migrate. Full sequence in our installation guide.
