Ridge-town retaining walls, the Teesta valley road and rockfall. Gabion boxes, revet mattresses and wire mesh made to IS 16014:2024 by an ISO 9001:2015 certified manufacturer.
Gangtok is built along a steep ridge, and almost every road, building plot and terrace in and around the town stands on a retaining wall. The main road down to the plains follows the Teesta valley, where slopes slip and rock falls every monsoon and walls are rebuilt every season.
We deliver gabion boxes, facia units and rockfall netting to contractors working in and around Gangtok from our Ethelbari works in North Bengal, by way of Siliguri and the Teesta valley.
Gabion walls hold up road formations and building terraces on the ridge.
Walls and rockfall netting along the cut slopes between the plains and Gangtok.
Reinforced soil walls with facia units where the hillside leaves no room for a wide gravity wall.
Gabions and mattresses at stream crossings and drain outfalls on the steep slopes.
Gangtok is reached from our Ethelbari works by road through Siliguri and up the Teesta valley. Monsoon slides close that road, so order and deliver material for the season before June.
Folded gabions are light and compact for the climb; stone is usually found on or near the site.
Heavy rain from June to September brings the slips that the walls are built to stop. The working season is October to May, with the clearest months in autumn and spring.
Hill walls: heavily galvanized boxes, 10×12 mesh, 2.70 mm wire; 3.00 mm where walls are tall or the boxes are handled hard.
Where land is short: PVC coated facia units for reinforced soil walls.
Rock cuttings: rockfall netting anchored at the crest — for large blocks the slope needs a designed system.
Send the clause from your drawing or BOQ and we will confirm the mesh type, wire diameters and coating against it before quoting.
Works 2 — Ethelbari, Birpara 735204. Our Ethelbari works in the Dooars of North Bengal serves Sikkim, Bhutan, North Bengal and the North East. Send your BOQ or drawing with the site location and we will quote a delivered price.
Yes — by road from our Ethelbari works through Siliguri and the Teesta valley. Plan deliveries before the monsoon, when slides can close the road.
Gabion walls suit them well: flexible and free-draining, so they cope with slow ground movement and heavy rain. Where space is tight, reinforced soil walls with facia units take less width.
Tell us your dimensions, wire specification and quantity — we'll come back with a quotation and lead time.
