S4 · Honeycomb-finish concrete · On request · built by teams we train

The visible-hexagon concrete road, built flush by teams we train

OC-HD 40 wet-set into a bed of the same M30–M40 concrete (or laid on plastic) and filled flush in one pour with a flowable blend on 10 mm aggregate: one monolithic layer with no cold joint, and the cell tops are the finish. No overlay, no grinding. U-nails anchor the grid to the base at the SOP spacing; the cell walls act as the joints, with expansion joints only at bay edges and structures; steel is kept to the minimum the site condition calls for.

Why it wins

  • Concrete stops at the top of the cell. No overlay, no groove cutting, no grinding: the hexagon pattern is the finish.
  • Built by teams we train. We train your contractor’s execution team and give our SOP and installation guide: for orders of 2,000 m² or more, our trainer comes on site for up to 3 days, once you confirm in writing that the site is ready and your execution team is available, and demonstrates about 100 m² of installation to the project agreement and the SOP; smaller orders are trained online at no extra cost. Mix design approved, slump per truck, finish height checked at the cell top, curing compound photographed.
  • The only concrete we sell. Offered on request where a client wants a concrete look and accepts the method. We never put the grid under a slab.
  • Faster than a jointed slab. Light traffic 24 h, 40% load at 7 days, full load at 28 days.

Where it fits

Plant roads · township and campus roads · premium parking · airport service corridors.

Method

Base by load class and CBR; a 75–100 mm bed of the same M30–M40 concrete with the grid wet-set into it and the cells filled flush in the same pour with a flowable blend on 10 mm aggregate (one monolithic layer, no cold joint), or the grid nailed on plastic; curing compound. Built by your contractor’s team, trained by GridMats with our SOP and installation guide; mix design approved before the pour; slump per truck; finish height checked at the cell top.

Choose S4 when

  • The client or consultant requires a concrete finish
  • A visible hexagon concrete surface is wanted
  • Areas where the specification calls for concrete

Not ideal when

  • Lowest cost or permeability is the priority: S1 or S2 usually costs less
  • Full load is needed before 28 days

What we need from you

  • Area: length × width, or m²
  • Location: city or a map pin
  • Heaviest vehicle and vehicles a day
  • Soil CBR if you have it, or the soil type
  • The finish you want
  • A site photo or layout drawing

On site

Installation at a glance

The six steps, what you need and when it opens, on one page. The installation guide comes by email on request; the SOP, the hold-point checklists and the method statement for your site come with your order. We train your contractor’s team: on site for up to 3 days for orders of 2,000 m² or more once the site is confirmed ready, online at no extra cost below that; on-site training is built into the product rate (one PO).
