Ultrasac 42 gallon contractor bags are 3 mil trash bags made in the USA from at least 90% recycled material, with tie flap handles at the top and one at a time dispensing. They handle the heavy, bulky, and sharp waste that comes out of yard renovation, demolition, and property cleanouts, and they also work for storing soil in batches.
Homeowners, gardeners, and DIYers tackling dirty jobs will get steady use from a box. With dense material like soil, fill each bag partway so the finished load stays light enough to carry.

Contractor Bags for Sod Removal, Soil Storage, and Demolition Cleanup
If you are stripping weedy sod from a new bed, digging out soil you want to keep, or hauling debris from a remodel, you need bags that will not split at the bottom or tear at the neck when you carry them. These 3 mil bags handle that work.
You can seal up pulled turf and roots, hold excess topsoil until you are ready to fill raised beds, or stage bagged material for your compost pile. Indoors, they hold drywall, tile, and fixtures from demolition. The flap ties give you handles for carrying and a secure closure without separate twist ties. For the bulkiest jobs or big piles of loose fill, a wheelbarrow or bulk bag will move material faster than any trash bag.
What to Expect from the Ultrasac 42 Gallon Contractor Bags in Real Use
Verified purchasers consistently note the thickness right away and report that the bags hold their shape when packed with bulky or sharp edged debris. Owners describe them as thicker and larger than standard lawn bags, opaque enough to hide contents, and leak proof even with discarded drinks from large events. The flap handles hold up without stretching or tearing at the top while carrying.
On the land side, one gardener uses them to store soil in batches for neighbors to pick up. The same owner sealed weedy dug sod with heavy root soil inside and left the bags in a sunny corner, and within weeks the turf had mostly broken down into near compost. A family cleanout loaded with broken glass and sharp items produced no punctures.
Sharp ceramics are the main limit. A bathroom demolition job went well overall, but two bags tore from jagged tile and porcelain, so wrapping or breaking down those pieces before bagging helps.

Frequently Asked Questions
Can you kill sod and weeds by sealing them in plastic bags?
Yes. Sealing pulled sod or weeds in opaque plastic bags and leaving them in full sun blocks light and builds heat, which kills the grass and roots and starts breaking them down. Expect the process to take several weeks in warm weather and longer in cool seasons. The result can go into a compost pile to finish, but be aware that some weed seeds and tough perennial roots may survive if the bags do not get hot enough.
How much soil can you put in a 42 gallon contractor bag?
Volume is not the limit, weight is. A 42 gallon bag holds about 5.6 cubic feet, and a full bag of soil would weigh several hundred pounds. Five gallons of moist garden soil weighs roughly 40 to 50 lbs, so filling each bag with 5 to 10 gallons keeps loads manageable to carry. Set the bag in a wheelbarrow or cart before filling if you plan to move larger amounts.
Are contractor bags safe for bathroom demolition debris?
Contractor bags handle most bathroom demo waste, including drywall, cement board, fixtures, and tile, but broken porcelain and ceramic edges can slice plastic. Break large pieces down, set jagged pieces in with flat sides against the bag, and add a layer of cardboard or drywall scraps around sharp edges. Keep bags light enough to lift from underneath, and check your local disposal rules for toilets and large fixtures.
