Quality-focused River Sand sourced through verified suppliers and arranged by OM Group for construction projects across North and South Goa, subject to current availability, source documentation and applicable regulations.
River Sand is naturally deposited sand formed through the weathering, transport and deposition of mineral material by rivers and streams. It is used as a fine aggregate in construction when its grading, cleanliness and other relevant properties meet the applicable project specification.
IS 383:2016 recognises natural sand as a fine aggregate source for concrete, alongside crushed stone sand, crushed gravel sand and manufactured sand — River Sand is defined by its natural geological origin, not by any particular processing or application. Particle characteristics, grading and suitability vary by the specific deposit and lot, and are properly confirmed by actual testing rather than assumed from the material's name.
OM Group does not extract or manufacture River Sand. Instead, we operate as a construction-materials sourcing and supply partner, coordinating River Sand procurement through suitable external suppliers and sources where the required permissions, documentation and commercial availability are in place.
Our role is to simplify procurement for contractors, builders, developers and project teams — coordinating sourcing, quantity requirements, delivery and project-specific material requirements through one supply relationship, alongside the rest of OM Group's construction-materials range.
River Sand is a regulated natural resource in Goa. Extraction, transport and supply are subject to applicable environmental, minor-mineral and transit-documentation requirements administered by the relevant state authorities — including the permit and transit-pass framework maintained by Goa's Directorate of Mines & Geology for sand and other minor minerals — and these requirements, along with sourcing conditions, can change over time.
Because of this, source verification is a standard part of how OM Group coordinates River Sand supply — current availability and applicable documentation are confirmed as part of the procurement process for each requirement, rather than assumed from historical availability. Current source and availability should always be confirmed directly rather than assumed from this page.
Coordinated through verified external suppliers rather than an owned quarry or extraction site.
Checked as part of the procurement process for each requirement.

IS 383:2016 is the primary Indian Standard recognising natural sand as a fine aggregate source for concrete. IS 2386 (Parts 1–3) covers the relevant test methods — particle-size distribution, deleterious materials and organic impurities, and specific gravity, density and water absorption. Where River Sand is supplied for plastering or masonry mortar, IS 1542:1992 and IS 2116:1980 are the relevant references respectively. These standards are cited as general technical reference; OM Group does not claim conformity for any specific supply without current test documentation for that material.
IS 383 classifies fine aggregate into Zones I–IV by sieve analysis. "River Sand is always Zone II" is false — grading varies by the specific deposit and lot, and is established by testing the actual material, never assumed from the product name.
Fineness modulus is a numerical index of average particle size, derived from cumulative sieve results. A higher or lower value isn't inherently better — it's only meaningful against the specific mix design's target.
Sample → sieve stack of decreasing mesh size → material retained per sieve → percentage retained and passing calculated → particle-size distribution compared against the applicable specification. This is the method that establishes grading zone and fineness modulus for the specific material supplied.
For natural sand, IS 383 sets a silt-content limit, assessed either by the field silt-jar method or by laboratory determination of material finer than 75 microns. These two tests are not interchangeable and can produce different practical readings — a supplier or buyer citing "silt content" should be clear which test the figure comes from. No specific silt percentage is published for OM Group's supply without current test data for that material.
Moisture content affects a sand's apparent volume — bulking — which matters directly for volumetric measurement and batching. No assumed tonnes-to-cubic-metre conversion is published, since the relationship depends on bulk density, moisture condition and measurement basis at the time of loading — genuinely variable information, not a constant.
River Sand and M-Sand are both used as fine aggregate, but they differ in how the material originates: River Sand is naturally deposited sand, while M-Sand is manufactured by processing rock.
| River Sand | M-Sand | |
|---|---|---|
| Material origin | Natural | Manufactured |
| Formation | Weathering, transport, deposition | Crushing and grading |
| Particle characteristics | Often rounded to sub-rounded, varies by source | Typically more angular |
| Grading | Determined by actual sieve analysis | Determined by actual sieve analysis |
| Concrete standard | IS 383, where used for concrete | IS 383, where used for concrete |
| Supply | Dependent on lawful natural source availability | Produced through OM Group's own manufacturing operations |
| Source traceability | Particularly important given current regulatory conditions in Goa | Production source is directly identifiable |
| Availability | Subject to extraction controls and current regulatory conditions | Dependent on plant production and logistics |
Neither is automatically "better" for every application — suitability depends on grading, cleanliness and project specification. OM Group provides M-Sand through its own established manufactured-sand supply capability, and can also coordinate River Sand sourcing when a project specifically requires natural sand and a suitable, documented source is available. For full production and grading detail on the manufactured option, see M-Sand.
Vs Plaster Sand. Natural sand is one of the source types IS 1542 recognises for plastering — but suitability still depends on the material's actual grading, not the source alone. See Plaster Sand.
Vs Washed Sand. Orthogonal concepts — a River Sand can be washed, and a manufactured sand can be washed. Washing is a process, not a source category. See Washed Sand.
Vs Concrete Sand. River Sand names a source; Concrete Sand names an application. A River Sand can serve as concrete sand when it meets IS 383's requirements — but what OM Group supplies for that application by default is M-Sand. See Concrete Sand.
Vs Sea Sand. Not interchangeable despite both being natural sources. Reinforced concrete use requires attention to chloride and other deleterious-material limits that sea sand's marine proximity makes particularly relevant — untreated sea sand should not be assumed suitable for reinforced concrete on the basis of particle size resembling river sand.
Vs Stone Dust. River Sand is naturally deposited; stone dust is a crushing by-product, not classified to any grading standard. Visual similarity establishes nothing about specification compliance.

River Sand is naturally deposited sand formed through the weathering, transport and deposition of mineral material by rivers and streams, used as fine aggregate when its properties meet the applicable project specification.
Natural sand is sand formed by natural geological processes rather than by crushing rock — River Sand is one type of natural sand, recognised as a fine aggregate source under IS 383:2016.
Concrete, RCC, RMC, masonry mortar and plastering, where the material's grading and properties meet the applicable project specification.
Yes, where its grading, cleanliness and other relevant properties meet the applicable IS 383:2016 requirements and the project's mix design.
Yes, subject to the same grading and specification requirements as any fine aggregate used in reinforced concrete.
Yes, where the material's grading matches the plant's mix design requirements.
Grading is the particle-size distribution of the specific material, established by sieve analysis against IS 383's zone classifications — it varies by deposit and lot and is never assumed from the product name.
Sieve analysis passes a sample through sieves of decreasing mesh size to determine particle-size distribution.
Fineness modulus is a numerical index of average particle size, derived from sieve analysis, used to characterise grading.
Silt refers to fine material within the sand, limited under IS 383 for natural sand and assessed by either the field silt-jar method or laboratory determination of material finer than 75 microns.
Not exactly — the field silt-jar method and the laboratory 75-micron determination are two different tests that can produce different practical readings. A silt figure should always specify which test it comes from.
Moisture affects the sand's apparent volume (bulking) and the effective water content of a batched mix, which matters for accurate volumetric measurement and batching.
Bulking is the increase in a sand's apparent volume caused by moisture content — it affects volumetric measurement and is not represented by a single fixed conversion figure, since it depends on bulk density and moisture condition at the time of loading.
Yes — natural sand is one of the source types IS 1542 recognises for plastering, subject to meeting the standard's grading and cleanliness requirements.
Yes, subject to the grading requirements relevant to masonry mortar under IS 2116:1980.
Yes — washing is a processing step that can be applied to River Sand, distinct from the sand's natural origin.
River Sand is naturally deposited; M-Sand is manufactured by crushing and grading rock. See the comparison table above for the full breakdown.
Neither is automatically better — suitability depends on grading, cleanliness and project specification, and in Goa specifically, on whether a lawful, documented River Sand source is currently available.
River Sand names a natural source; Plaster Sand names a grading specification under IS 1542. A River Sand can be plaster-grade if it meets that specification.
River Sand describes a natural source; Washed Sand describes a processing step. A River Sand can be washed, and a manufactured sand can also be washed.
River Sand names a source; Concrete Sand names a concrete application. A River Sand can serve as concrete sand where it meets IS 383's requirements.
Both are natural sources, but sea sand's marine proximity makes chloride and other deleterious-material limits particularly relevant for reinforced concrete — the two should not be assumed interchangeable based on particle size alone.
River Sand is naturally deposited and can meet a recognised grading specification; stone dust is an uncontrolled crushing by-product not classified to any grading standard.
