We are mining & infrastructure
Mine. Construct. Evolve. — engineered sand, aggregates and infrastructure for modern India.
{ Our Divisions }
Two decades of responsible quarrying. We extract black basalt rock and process construction aggregates under strict government compliance — supporting the core of every structure we serve.
Engineered concrete and plaster sand manufactured on Japanese VSI technology — zero silt, zero clay, consistent gradation. The eco-friendly answer to river sand, load after load.
The division we are building next. Roads, earthwork and heavy civil are the natural extension of a quarry, a crusher and a sand plant already under one custody chain. The material and the fleet are in place, and we are pursuing our first packages now.
Residential, commercial and industrial development, plus redevelopment work that upgrades ageing structures rather than simply replacing them. Smart use of resources, built on our own engineered materials.

{ How We Work }
We study the deposit, the site and your specification — grades, volumes and logistics — before a single machine moves.
Mining plans, environmental clearances and government compliance are locked in — responsibility is the first deliverable.
Controlled blasting, crushing and VSI shaping turn raw basalt into consistent, construction-grade material.
Every batch is tested for gradation, silt content and strength — so what reaches your site performs exactly as promised.
Our own fleet dispatches on schedule, with documentation and after-supply support that keeps your pour on time.

{ What Our Clients Say }
Silt-free, every single load. Our cube results improved within the first month of switching to Capitan concrete sand.
Dispatch discipline is what sets Capitan apart. The pour schedule has never slipped because of material.
Consistent gradation means predictable concrete. We stopped over-ordering cement to compensate for bad sand.
Their test documentation is the cleanest I've reviewed — gradation curves and silt reports with every batch.
One vendor for basalt, aggregates and engineered sand across three sites — logistics got dramatically simpler.
Plaster sand with no organic impurities — finishes cure evenly and rework has dropped to near zero.
Full strength in seven days, exactly as specified. The lab reports match what we see on site.
After the dredging ban we needed a river-sand replacement we could trust. We found it — and never looked back.
{ FAQ }
Sand manufactured from basalt rock on VSI (vertical shaft impactor) technology. Particles are cubical and consistently graded — free of the silt, clay and organic impurities found in natural river sand.
It meets river-sand standards with better particle locking, stronger cement bonding, lower water absorption and higher compressive strength — while being fully eco-friendly after the dredging ban.
Yes. Our concrete sand conforms to Zone II gradation requirements for RCC work, and every dispatch carries a batch quality certificate. Third-party lab reports are available on request.
We deliver across Vasai, Virar, Mira-Bhayandar and greater Mumbai on our own fleet. Minimum order depends on material and distance — send us your site pin and we'll confirm same day.
Every production run is tested for gradation, silt content and moisture. Quarry-to-plant sourcing means the raw material never changes — so neither does the output.
Yes — roads, earthwork and heavy civil packages, backed by our own material chain and machinery. Share your BOQ through the contact form and our projects desk will respond.
Use the enquiry form below or reach us on WhatsApp. Share material, approximate monthly volume and site location — quotes are typically issued within one working day.
Concrete sand is coarser and graded to Zone II for structural RCC work, giving better particle interlock and compressive strength. Plaster sand is finer and screened for a smooth finish on walls and ceilings, so renders cure evenly without surface cracking.
Yes. Alongside engineered sand we supply black basalt rock, 10mm and 20mm cubical aggregates, crushed stone dust, and GSB and WMM road-base mixes — all from the same quarry, so gradation stays consistent across your order.
We can. Our VSI plant lets us tune the output curve to a specified fineness modulus. Send us your mix design or target gradation and our technical team will confirm what we can hold and at what tolerance.
For sites within Vasai, Virar and Mira-Bhayandar we typically dispatch same or next working day. Greater Mumbai deliveries depend on load size and traffic windows — our dispatch desk confirms a slot when the order is placed.
In most cases, yes. Consistent gradation and zero silt mean less cement is needed to hit the same strength, and there is no wastage from washing or screening on site. Add stable supply pricing and the delivered cost per cubic metre usually works out lower.
Every quarry we operate runs under an approved mining plan with the required environmental clearances. Dust suppression, controlled blasting windows and phased restoration are part of the operating routine, not an afterthought.
Yes. We supply and execute for EPC contractors and institutional buyers, and can provide the batch documentation, test certificates and invoicing formats those projects require. Reach out through the form and our projects desk will take it forward.
