For decades, Concrete Lintels and Slab Casting have been the default choice for small-span roofing solutions in low-rise structures, walls, and sheds. But as construction practices evolve, so do smarter, faster, and more economical alternatives. One such innovation gaining attention across the industry is the use of Precast Plot Stones as Lintels.

With over 15+ years of precast expertise, Drsti Precast is a trusted name in innovative, ready-to-use construction solutions—and our high-quality Precast Plot Stones designed specifically to replace cast-in-place roof lintels in compound walls, pump rooms, toilets, garages, small sheds, and similar structures.

What Are Precast Plot Stones? 

Precast plot stones are reinforced concrete units designed to act as lintels or roofing panels in small spans. Unlike traditional cast-in-place lintels or RCC slab roofs, these stones are:

• Pre-manufactured

• Fully cured

• Easy to install

• Reusable and replaceable

They are ideal for non-load-bearing roofing needs, especially in compound walls, toilet blocks, pump rooms, guard cabins, agricultural sheds, and more.

Problems with Traditional Concrete Roof Slabs

Before we look at the benefits of plot stones, consider the challenges of conventional RCC roofing:

• Requires shuttering and centering

• Needs curing time of 7–21 days

• Involves higher labor and material cost

• Delays construction timelines

• Difficult to modify or repair

That’s where Drsti Precast Plot Stones provide a smarter alternative.

Why Choose Precast Plot Stones Over Concrete Roof?

• No Shuttering or Curing Required : Ready-to-use units that save time, materials, and water.

• Fast Installation : Complete your roofing or lintel work in hours not days.

• Cost-Effective Solution : Lower expenditure on cement, steel, and labor.

• Minimal Equipment Needed : No mixers, scaffolding, or formwork required.

• Removable and Reusable : Can be lifted, shifted, or replaced easily during repairs or layout changes.

• Cleaner Site Execution : No wet concrete, less mess, and zero curing delays.

Where to Use Precast Plot Stones

• Compound wall roofing/lintels

• Toilets, bathrooms & pump rooms

• Temporary site shelters or security rooms

• Farm buildings and animal sheds

• Rural housing and low-cost housing

• Rooftop tank platforms

• Shops, godowns, and garage openings

All units are factory cured and tested for strength and durability.

How to Use Precast Plot Stones as Lintels: Full Guidelines

• Determine Span - Use plot stones for spans up to 6 feet. For longer spans, consult a structural engineer.

• Proper Support - Ensure minimum 4–6 inches of end bearing on both walls.

• Tight Placement - Align stones side-by-side with no gaps. Fill joints with mortar if needed.

• Covering - Apply a waterproofing sheet or concrete screed above the plot stones.

• Avoid Point Loads - Do not place tanks, columns, or heavy machines directly on plot stones.

• Inspection - Check annually for cracks, joint gaps, or leakage, and replace damaged stones easily if needed.
