Walk-behind petrol slab cutter with diamond blade for concrete control joints, road trench edges and industrial floor work — stocked at Multi Trade Combines, Guwahati.
A slab cutter — also called a floor saw or road saw — is a walk-behind machine fitted with a large-diameter diamond blade that cuts straight, controlled lines through concrete and asphalt. It is fundamentally different from a handheld angle grinder or a brick cutter in scale and application: it can cut 60–100 mm deep in a single pass on a 150 mm thick concrete slab, maintaining a straight line over 30 metres or more. This makes it indispensable for two operations: cutting control and expansion joints in large-area concrete pours (industrial floors, airport aprons, plaza decks), and cutting neat, parallel edges in road pavements before utility trenches are dug for cables, water mains and drainage.
Guwahati's rapid urban expansion — new road widening projects, flyover deck slabs, large industrial plots being paved for logistics parks — creates strong demand for slab-cutting equipment in the Northeast. Road maintenance contractors cutting bitumen and concrete patching edges, civil contractors laying HDPE conduit under recently paved roads, and industrial floor contractors laying large format concrete pads all need walk-behind floor saw capacity. Multi Trade Combines supplies this equipment from our AT Road, Guwahati counter. Petrol-driven models are the standard for outdoor road work; enquire for electric models for indoor factory-floor use.

Road agencies — PWD Assam, Guwahati Metropolitan Development Authority, and national highway project contractors — specify slab cutting for all utility reinstatements and for scheduled joint cutting in cement concrete road projects funded under PMGSY and Smart City schemes. An uncut concrete road slab in Northeast India's temperature range of 5°C (winter) to 38°C (summer) will develop random cracking within weeks of pour without properly timed joint cuts. The slab cutter makes these cuts at the right time with the right depth and spacing. It pairs on a project with the concrete mixer for the pour, the concrete vibrator for compaction, and the plate compactor for sub-base preparation — all available from Multi Trade Combines as part of a complete construction machinery supply.

A walk-behind floor saw (slab cutter) is used for cutting control joints and expansion joints in newly poured concrete slabs, cutting through existing concrete or asphalt pavements for utility trench installation, and resurfacing road patches to defined edges. The diamond blade produces a clean, straight cut that a handheld grinder cannot match for length or depth. Call +91 91812 13332 for specifications.
Control joints should be cut within 4–12 hours of concrete finishing, before random shrinkage cracking initiates — this is the critical window where the concrete has hardened enough to walk on and resist blade chipping but has not yet developed internal shrinkage stress that causes uncontrolled cracking. In Northeast India's variable temperature and humidity, timing varies by season and mix design. WhatsApp +91 76359 98826 for equipment availability and delivery schedule.
