Concrete & Heavy Debris Dumpsters in Janesville, WI

Concrete is a different rental to everything else we do. With household junk or demolition debris you are buying space in a box. With concrete you are buying weight, and you will hit the weight limit long before the container looks full. That is not a rule we made up to sell more boxes — it is what a truck axle can legally carry down Milton Avenue.

Here is the arithmetic. A cubic yard of broken concrete runs somewhere around 3,700 to 4,000 pounds. Fill a 10 yard container to the rails and you are asking a driver to lift close to twenty tons. It will not happen. In practice a clean concrete load sits two to four feet deep in a low-side 10 yard, and that is a full load. Everyone who has never done it before looks at the box on pickup day and thinks it is half empty. It is not.

The second rule is just as important: concrete has to be a dedicated single-material load. Clean inert material — concrete, brick, block, asphalt, rock, and dirt in its own separate load — can go to a crusher or recycler and come back out as base course. Throw in a few 2x4s, a bag of household trash, some old fence posts and a roll of carpet and the whole thing is now mixed waste headed for a landfill, at landfill pricing. One contaminated corner ruins the whole box. Keeping it clean is the cheapest thing you can do on the job.

Little J's has been running these loads out of the yard at 103 S Grant Ave since 2012. Flat rate covers delivery, pickup, the weight allowance for that material, disposal and tax, on a standard seven-day rental with same-day or next-day delivery when we have a truck free. Every residential drop gets driveway protection boards, which matters more here than on any other job we do. Call (608) 531-8367, tell us the square footage and the thickness, and we will tell you how many boxes it takes.

Every other kind of dumpster runs out of room. This one runs out of pounds. Understanding that up front stops most of the surprises.

Rough weights you can plan around

• Broken concrete: about 3,700-4,000 lb per cubic yard
• Brick and block: roughly 3,000-3,500 lb per cubic yard, a bit less if it is hollow block
• Broken asphalt: about 3,000-3,500 lb per cubic yard
• Dirt and soil: about 2,000-2,700 lb per cubic yard dry, considerably more when it is wet clay
• Sod: heavier than people expect, because it is mostly wet soil

Translate that into a slab. A hundred square feet of four-inch concrete is about two and a half tons. A twenty-by-twenty two-car driveway apron at four inches is therefore near ten tons before you count the thickened edges — that is more than one load. Six-inch work, which is what most farm pads, silo bases and commercial aprons are, is half again heavier per square foot.

What this means practically

We give you a fill line on the container and we mean it. If the box comes back over weight the driver either leaves material behind or the load costs more, and neither of those is a good morning for anybody. Break slab into pieces you can lift and stack rather than heaping rubble — flat pieces laid in courses fit more tonnage per box than jagged chunks with air between them.

If your project is bigger than one box, say so when you book. We would rather schedule three staged 10 yard swaps than have you discover it halfway through a Saturday. See the 10 yard container spec for dimensions and the fill line we work to.

Most of the concrete we haul in Janesville comes out of the ground for one of two reasons: it heaved, or it is being replaced as part of something bigger.

Frost heave season

Southern Wisconsin's freeze-thaw cycle is brutal on flatwork. Water gets under a slab, freezes, lifts it, thaws, and drops it back slightly out of line. Do that thirty winters running and you get the cracked, tilted, trip-hazard sidewalks and aprons you see all over the older neighbourhoods. Once a panel has heaved there is no fixing it with patch — it comes out. Spring and early summer, once the ground has dried out, is when most of that work happens here, and it is our busiest stretch for 10 yard concrete boxes.

Sizing common jobs

• City lot sidewalk, 4 ft wide, 4 in thick: roughly forty to fifty linear feet per load
• Single-car driveway, 10x40 at 4 in: plan on three or four 10 yard loads
• Patio, 12x16 at 4 in: usually one full load, maybe a bit over
• Garage slab, 20x22 at 4 in: four loads or more, plus thickened edges and footings
• Front steps and stoop: almost always heavier than they look — solid pours, not hollow

Footings and dirt

Footings are deep, dense and often have the most steel in them. Dirt from a footing dig should go in its own container rather than on top of concrete — crushers do not want soil in their feed. If you are digging new footings after the old work comes out, call 811 first; that is a legal requirement, not a courtesy.

Teardowns that produce both structure debris and slab are covered on our demolition debris page — run two boxes, not one.

From roughly March into April, town and county road authorities across Wisconsin post seasonal weight limits. The reason is simple: as frost comes out of the ground, the subgrade under a rural road turns soft, and a heavy axle will pump and break the pavement. Concrete loads are exactly the kind of weight those postings exist to keep off.

How it affects your job

• Deliveries and pickups on posted town roads out toward Orfordville, Footville, Clinton and Brodhead may be delayed or rerouted until restrictions lift
• We may need to run a lighter load, meaning more swaps on the same amount of material
• Farm lanes and gravel drives soften badly in thaw — a fully loaded truck can rut them or sink
• Postings can come on and off with the weather rather than on a fixed calendar

None of this is a reason to avoid spring work. It is a reason to book early and to be honest with us about where the site is. If the address is on a gravel town road eight miles out, tell us at booking. We will plan the route, the load size and the timing around it rather than discovering the problem with a truck already committed. Postings are published by the relevant road authority; general information on Wisconsin's seasonal weight restrictions is available from WisDOT.

Once the ground firms up in late spring, everything opens back up and we run full loads anywhere in the county. That is also when the flatwork replacement rush starts, so if you know you are tearing out a driveway in June, put yourself on the schedule in May. Coverage across the county is listed on our service area page, including Orfordville and the surrounding townships.
