Picking the right topsoil in Kingston can make or break a new lawn, garden, or grading job. Get it right and your grass fills in fast, your beds drain well, and your yard sits level. Get it wrong and you fight weeds, puddles, and thin patches for years. So before you order a load, it helps to understand what you are actually buying.
At M. Riddle Excavating, we have hauled and spread soil across Frontenac County for over 20 years. In short, we know the difference between good dirt and cheap fill. This guide walks you through the choices so you order the right product the first time.
Topsoil Kingston Basics: Screened Topsoil, Triple Mix, and Fill
Not all “dirt” is the same. When you shop for topsoil in Kingston, you will usually hear three terms. Each one suits a different job, so matching the product to the task saves you money.
- Screened topsoil: natural topsoil run through a screen to remove rocks, roots, and clumps. It is clean, uniform, and easy to spread.
- Triple mix: a blend of topsoil, compost, and peat or manure. It holds moisture and feeds plants, so it shines in gardens and raised beds.
- Fill: lower-grade material used to raise grades or backfill holes. It is not meant for growing.
Because these products serve different purposes, mixing them up is a common and costly mistake. For example, spreading fill under new sod almost always leads to poor growth. That said, using pricey triple mix as levelling fill wastes good money on the wrong job.
When to Use Each Type
Here is a quick match-up to help you plan.
- New lawn or sod: screened topsoil, roughly 100 to 150 mm deep.
- Raised beds or vegetable gardens: triple mix for nutrients and moisture.
- Levelling low spots or grading: fill for the base, then a topsoil cap on top.
- Overseeding a thin lawn: a thin layer of screened topsoil to top-dress.
If you are unsure which product fits your yard or how much you need, just call and describe the project. We will steer you to the right load rather than the biggest one.
How to Judge Quality Before You Buy Topsoil
Good soil looks and smells alive. Poor soil looks pale, dry, and lifeless. Because photos can hide flaws, ask to see a sample before a large delivery. We break this down further in our guide on how to spot good soil, but here are the key signs.
- Colour: dark brown or black usually means good organic content.
- Texture: crumbly and loose, not sticky clay or loose sand.
- Smell: earthy, not sour or chemical.
- Debris: few rocks, no plastic, glass, or big roots.
- Moisture: slightly damp, not soaked into mud or baked into dust.
Grab a handful and squeeze it. Quality topsoil holds together lightly, then breaks apart when you poke it. However, if it stays in a tight, shiny ball, it likely carries too much clay.
Questions to Ask Your Supplier
A straight answer tells you a lot about a supplier. So ask these before you order:
- Is the topsoil screened, and what screen size did you use?
- Where does the soil come from?
- Has it been tested or checked for weed seeds and contaminants?
- What is the delivery charge and minimum load?
- Can I see a sample first?
Because we source and screen our own topsoil and gravel, we can answer all of these plainly. In short, you should never feel like you are guessing about what lands in your driveway.
How Much Topsoil Do You Need?
Ordering the right amount saves a second delivery fee and avoids a leftover pile. Topsoil is sold by the cubic yard. One cubic yard covers a set area depending on how deep you spread it.
Use this simple table as a starting guide for coverage per cubic yard.
| Spread Depth | Approx. Coverage per Cubic Yard | Best For |
|---|---|---|
| 25 mm (1 in) | ~30 m² (325 sq ft) | Top-dressing a lawn |
| 50 mm (2 in) | ~15 m² (160 sq ft) | Overseeding, light fill |
| 100 mm (4 in) | ~7.5 m² (80 sq ft) | New sod, garden beds |
| 150 mm (6 in) | ~5 m² (55 sq ft) | Deep beds, low spots |
To estimate, measure your area in square metres, then multiply by your depth in metres. That gives you cubic metres, which we convert to yards for you. If math is not your thing, no problem. Send us your measurements and we will size the load.
A Worked Example
Say you are laying new sod on a 60 m² back yard. You want a 100 mm bed of screened topsoil. At roughly 7.5 m² per cubic yard for that depth, you need about 8 cubic yards. So one delivery does the job with a little to spare for settling.
We always suggest a small buffer, because soil compacts after rain and foot traffic. In short, a touch extra beats coming up short near the finish line.
Delivery and Seasonal Timing in Frontenac County
Timing matters more than most people expect. Because our springs are wet and our winters are long, the calendar shapes your plan.
- Spring: great for lawns and gardens, but wet soil can be hard to spread. Wait for it to dry a little.
- Summer: good all-round window; water new sod well in the heat.
- Fall: excellent for seeding and levelling before winter.
- Winter: deliveries slow down; frozen or snow-covered ground is tough to grade.
Because demand spikes in spring, book delivery early. That way you get your soil when the weather cooperates, not weeks after.
Think about access, too. A dump truck needs a clear path and a firm spot to tip the load. So clear vehicles, low branches, and gates before we arrive.
Where Should the Pile Go?
Pick a spot close to the work but off soft lawn if you can. A driveway or gravel pad protects your grass from ruts and stains. For larger projects, we can place multiple piles to cut down on wheelbarrow trips.
Grading, Drainage, and When You Need More Than Topsoil
Sometimes topsoil is only the last step. If your yard slopes toward the house or holds water, you may need proper grading first. In that case, we bring in fill, shape the grade, then cap it with screened topsoil.
Water flow is not just a nuisance; it can also be a rule. If your property sits near a creek, wetland, or floodplain, larger regrading may need approval. Your local conservation authority handles permits and floodplain rules for that kind of work. So check before you move a lot of earth near water.
For clearing brush and stumps before soil goes down, our land clearing services prep the site properly. In short, a clean, well-graded base makes your topsoil work far harder for you.
Building Up a New Lot or Bed
For a fresh lawn on rough ground, the layered approach works best:
- Clear debris, roots, and large rocks.
- Rough-grade with fill to set drainage away from buildings.
- Add a topsoil cap of 100 to 150 mm.
- Rake, roll lightly, then sod or seed.
Because each layer has a job, skipping one usually shows up later. For example, sod laid straight over hard fill dries out and yellows fast.
Why Local Knowledge Pays Off
Every yard in the Kingston area has its own quirks. Some sit on rock close to the surface. Others hold water in spring. Because we work this ground every week, we read a site quickly and match the right soil and grade to it.
We also keep our loads honest. When you order screened topsoil from us, you get clean, consistent material, not a mystery mix. That is how we have earned a 4.9-star reputation over two decades here.

Frequently Asked Questions
What is the difference between topsoil and triple mix?
Screened topsoil is natural soil cleaned of rocks and roots, ideal for lawns and levelling. Triple mix blends topsoil with compost and peat, so it holds moisture and feeds plants better in gardens and raised beds.
How deep should topsoil be for a new lawn?
Aim for roughly 100 to 150 mm of screened topsoil under sod or seed. That depth gives roots room to grow and holds enough moisture through our hot summers.
How much topsoil comes in one load?
Load sizes vary by truck and by your access. We match the delivery to your project, so send your measurements and we will confirm the cubic yards you need before you commit.
Do I need a permit to regrade my yard near water?
Small topsoil jobs rarely need approval. However, larger regrading near a creek, wetland, or floodplain may require a permit from your local conservation authority. Check first to stay onside.
When is the best time to order topsoil in Kingston?
Late spring through fall works best for spreading and growing. Because spring demand is heavy, book early so your soil arrives when the ground is workable and the weather holds.
