Systems and products
A system is what gets built: the finish you see, the load it carries, the base and the method. A product is what GridMats supplies for it. Start with the three questions below: they give you a system, its installed cost per square foot and when it opens to traffic. Product prices for procurement teams follow further down.
Cell confinement is not new: it was developed with the US Army Corps of Engineers in the late 1970s and has been used worldwide since. In India, cell-filled concrete pavement is among the new technologies for rural roads under PMGSY. GridMats adds a recycled-plastic grid, tested at IIT Hyderabad and patented in India (Indian Patent 398992).

Four questions. The answer is your design and price: the system, how it is built, the cost per sq ft and for your whole project, and when it opens. Your free estimate then prices your own site.
Gross vehicle weight. The pavement itself is designed on the axle loads from your axle survey or VDF.

*Indicative, from completed sites and our cost sheets. Your free estimate prices your own site from its area, soil, rainfall and levels. The geotextile separation layer is a separate BoQ item, not included.
2 · Installed cost and time, system by system
Installed ranges from completed sites and our cost sheets, with the time to traffic. Every site is designed and priced from its own survey.
| System | Installed cost, indicative* | Opens to traffic | Heaviest vehicle | Finish | Product supplied |
|---|---|---|---|---|---|
| S1 Cement-treated gravel lead | ₹130–177/sq ft (₹1,400–1,900/m²) | Light vehicles at 3 days; trucks at 7, once the cubes reach 2 MPa | Vehicles up to 49 t gross | Hard grey, dust-free | OC-HD 40 (trucks) or OC-LW 40 (lighter traffic) |
| S2 Stone chip, gravel, pebble | ₹130–177/sq ft (₹1,400–1,900/m²) | Same day | Cars to trucks | Natural stone, permeable | OC-HD 40 or OC-LW 40; the 30 mm grid for paths and campus roads |
| S3 Grass and soil | ₹125–167/sq ft (₹1,350–1,800/m²) | At once on foot; vehicles in 4–6 weeks | Cars; fire-lane access on a designed base | Green | Grass paver 30 mm (cars), 20 mm (walkways) or OC-LW 40 |
| S4 Honeycomb-finish concrete | On request, priced per site; materials ₹214–265/sq ft (₹2,300–2,850/m²) on our cost sheets | Traffic at 7 days; full traffic at 14 days; full load at 28 days | Trucks up to 49 t gross | Concrete, visible hexagon | OC-HD 40 + concrete |
| S5 Grid at the GSB/WMM interface | Design-specific | Your contractor's asphalt programme | By design | Asphalt | OC-LW 40 (OC-HD 40 for the heaviest) |
| S6 Temporary roads and surfaces | ₹181–204/sq ft (₹1,950–2,200/m²) for the mats, reused site after site; ground levelling and a geotextile only | Same day; lifted and reused | Site traffic, crane pads | Top-covered mats, in colour | TC mats, Heavy Duty or Light Weight |
*Installed cost varies with local material availability, labour, transport, base design and site conditions; every site is priced from its own design. The geotextile separation layer is a separate BoQ item, not included. For comparison, an IRC:58 concrete road runs ₹269–297 per sq ft (₹2,900–3,200 per m²) on our cost sheets and needs about 28 days of curing before full load. Heaviest vehicle is the gross weight; the pavement is designed on the axle loads from your axle survey or VDF. Product prices for procurement are in section 3.
Defect liability: 1 year (DLP), our standard practice. After the training visit, your team shares project status updates (photographs, test reports, and any roadblocks or challenges) at each hold point and at the intervals set in the project agreement; the DLP applies only when these updates have been shared.
3 · Products for procurement
For buyers ordering the grid itself: sizes, lab tests and the price by order size. Most projects start from the installed system cost above. On a project quote the product rate also carries the training of your contractor’s team, so there is one PO. Datasheets are under Resources.
Every product ships with its dimensions, mass, material (100% post-consumer polypropylene for the grids), certificates (GreenPro, patent 398992, PCT WO2023/100191), load tests with the laboratory named, pack size and the lead time confirmed with each purchase order. Terms: 100% advance with the order, GST 18% extra, transport at cost.

Load tests are laboratory compression tests on a single panel. They compare panels; the capacity of a pavement comes from the base designed for its traffic and soil.

The ladder is the base product price. On a project quote, the on-site training of your contractor’s team is built into the product rate: one PO. Online training is at no extra cost. The tier is set by the square metres on one purchase order. A 12-month rate contract for a group, a park or a repeat buyer is priced in the last column whatever the size of each call-off. Prices ex-works Bengaluru; GST 18% and freight extra.
