Rock Salt (Treated)

Think of a square box or a kitchen stove that is 3ft by 3ft by 3ft.

One cubic yard is roughly 9 - 14 wheelbarrow loads.

Our trucks can carry 1 cubic yard to 6 cubic yards per truck load. We have no minimum order quantity, and simply charge a flat rate.

We pretty much deliver anywhere in and outside of Boston. Our trucks travel up but not limited to 50 miles in any direction.

We also service the cape. Think you are to far? Just call us and check.

Rock Salt (Treated) – High-Performance Ice Melt for Extreme Winter Conditions

Our Treated Rock Salt is enhanced with liquid additives to deliver faster, longer-lasting ice melt performance—even in sub-zero temperatures. Designed for serious winter weather, this pre-treated salt clings better to surfaces and starts working on contact, making it ideal for high-traffic areas like driveways, walkways, parking lots, and commercial sites.

Why Choose Treated Rock Salt?

• Fast-Acting & Long-Lasting – Begins melting ice immediately and stays effective longer than untreated salt.
• Low Temperature Performance – Works in colder conditions where standard salt falls short.
• Improved Adhesion – Sticks to surfaces better, reducing bounce and scatter during application.
• Cost-Effective Coverage – Requires less product per application thanks to increased efficiency.

Perfect for Boston’s unpredictable winter weather, our treated rock salt helps homeowners, contractors, and municipalities keep surfaces safe and clear with less effort.

Order in bulk or by the bag and get ready for whatever winter throws your way.

🚚 Delivery Options & Scheduling

We offer same-day and next-day delivery services based on order timing and availability. Delivery windows vary depending on the day of the week:

• Weekends tend to fill up quickly, so we encourage customers to place weekend orders early to secure preferred time slots.

Once your order is placed, we’ll reach out to confirm your delivery window and any special instructions for drop-off.

📍 Where We Deliver

All deliveries are made via dump truck, with options for:

• Curbside Delivery – We'll unload your materials directly onto your driveway or just off the public roadway.
• On-Property Delivery – Upon request, and with customer permission, we will drive onto your property to unload materials in your yard or another designated area.

Important: If you request on-property delivery, you must agree to waive liability for any potential damage to driveways, lawns, or other surfaces due to the weight of the loaded dump truck. Our team takes every precaution, but customer acknowledgment is required for this type of service.

• No minimum order required – we’re happy to deliver whether you need a small amount or a full load.
• Full truckload capacity: Up to 6 cubic yards per delivery.
• All materials are delivered loose – not bagged – and unloaded from the rear of the dump truck.

📝 Before You Order

To ensure a smooth delivery, please consider the following:

• Make sure the drop location is clear of vehicles, obstructions, or overhead wires.
