What is ¾ clear limestone? Uses, projects and delivery in the Toronto

If you have been researching materials for a drainage project, driveway repair, or a patio build, you have probably come across the term “clear stone” more than once. Homeowners searching for gravel delivery in Toronto often run into this product first and are not entirely sure what it is, when to use it, or how much to order.

At We Deliver Gravel, ¾ Clear Limestone is one of our most-requested aggregate products, and we get questions about it constantly. Here is a straightforward guide covering everything you need to know before you place your order.

What is ¾ Clear Limestone?

¾ Clear Limestone is a crushed, angular stone that has been washed to remove the dust and fine particles left over from the crushing process. It is roughly ¾ of an inch in diameter and has a clean, grey-white appearance.

The keyword in the name is “clear.” It refers to that washing step: the fines have been removed, leaving only the larger, clean pieces of crushed limestone behind. Because there are no fine particles binding the stones together, the material does not compact into a solid layer. It stays loose, with open space between each piece.

That might sound like a drawback, but it is actually the entire point. Water passes freely through the gaps rather than pooling on the surface or pressing against your foundation. This is what makes ¾ Clear Limestone the go-to aggregate for drainage applications across the GTA.

Does ¾ clear limestone compact?

No. Because the fines have been washed out, ¾ Clear Limestone stays loose rather than binding together under pressure. This is intentional. It is chosen precisely for situations where you want water to flow down and away rather than be blocked by a dense, compacted layer. If you need a material that compacts firmly for a driveway or patio surface, Granular A or Limestone Screenings are the right call for those layers instead.

Common uses for ¾ Clear Limestone

This is where the product really earns its reputation. The applications are broader than most people expect.

• Foundation and perimeter drainage: One of the most critical uses for ¾ clear limestone is around the perimeter of a home’s foundation. When placed alongside weeping tile or a perforated drainage pipe, it creates a free-draining channel that carries water away from the foundation walls. If you have ever noticed moisture seeping into your basement or damp patches along your home’s exterior walls, this material is often part of the proper long-term fix.
• Under patios, sheds and outdoor structures: Before laying a patio base or building a shed pad, many contractors place a layer of ¾” clear limestone beneath the compacted base material. It acts as a drainage barrier that prevents frost heaving and moisture buildup under the structure over time.
• Window well drainage: A very common issue in older Toronto and Vaughan homes is water pooling at the bottom of basement window wells and eventually seeping through. Placing 6 to 10 inches of ¾-clear limestone at the base of the well resolves this quickly and cost-effectively.
• Backfilling around pipes and utility work: Plumbers and utility contractors use ¾ clear limestone to backfill around sewer lines, catch basins, and underground installations. It supports the pipe without trapping water around it.
• Driveway sub-base layer: While ¾ clear limestone is not typically used as the top surface of a driveway, it works well as a drainage layer beneath the main base, particularly in areas where the native soil drains poorly. For more on building a solid driveway foundation, see our guide on driveway gravel suppliers in Toronto.
• Pool surrounds and outdoor entertaining areas: Because it drains quickly, stays clean, and holds up to foot traffic, ¾ Clear Limestone is a practical choice around inground pools, patio edges, and outdoor entertainment zones.

Why ¾ Clear Limestone is the top choice for drainage

The reason this product keeps showing up in drainage guides and contractor specifications comes down to one thing: permeability. When the fines are washed out, the void space between the stones is significant. Water flows straight down through the material instead of running sideways or sitting against your structure.

Compare that with compacted aggregates like granular A or limestone screenings, which are specifically designed to bind together and resist water movement. Each material has a purpose, but when drainage is the primary goal, ¾ clear limestone is the right product. Our post on sand vs gravel for drainage breaks down how different aggregates handle water flow if you want to compare your options before ordering.

Is clear stone the same as ¾ clear limestone?

Yes. In most GTA contexts these terms refer to the same product. “Clear stone” is the shorthand contractors use on job sites and in quotes. The “¾” specifies the stone size. roughly ¾ of an inch, and “clear” means the fines have been washed out. Some suppliers also carry ½ clear limestone, which is smaller but used in similar drainage applications. If you are ever unsure which size a project calls for, our team at We Deliver Gravel can help you confirm the right spec before you order.

¾ Clear Limestone vs limestone screenings: Which one do you need?

These two products get mixed up regularly, so it is worth being direct about the difference.

Limestone Screenings are fine-grained and compact firmly when wetted and rolled. They are used for levelling surfaces, bedding interlock pavers, and building firm, walkable pathways. You can read more about their specific construction applications in our post on why limestone screenings work for construction projects.

¾ Clear Limestone is not compact. Its entire value is in staying loose and letting water pass through freely.

The short version: if you want a firm, stable surface, use Limestone Screenings. If you want drainage, use ¾ Clear Limestone.

How much ¾ Clear Limestone do you need?

The right depth depends on the application. Here is a general reference:

• Foundation drainage alongside weeping tile: A minimum of 12 inches around and above the pipe
• Window well base: 6 to 10 inches
• Under-slab drainage for patios or sheds: 4 to 6 inches below the base layer
• Pool surrounds and surface areas: 3 to 4 inches as a top layer
