Shipping & Freight

For an order containing products from a single brand, shipping is a flat rate based on your order total:

  • Orders up to $5,000: $279
  • Orders $5,000 to $10,000: $347
  • Orders $10,000 and over: $517

These rates cover standard freight delivery to a commercial address. After you place your order, our team will confirm your delivery timeline within 1 to 3 business days.

Ordering from more than one brand? Multi-brand orders ship on separate freight and are quoted individually rather than at the flat rate above. Place your order or contact us first and we will confirm total freight before anything is finalized.

Liftgate service is not included in these rates. If your delivery location has no loading dock or forklift to unload the freight from the truck, liftgate service is required and will be added to your shipping charge. If you are unsure whether you need it, contact us before ordering.

Commercial delivery locations are preferred when available. Residential delivery, limited-access locations, and appointment scheduling may affect handling.

Lead times vary by product, manufacturer availability, and selected options. Some configured, special-order, or non-stock items require additional processing time before they ship.

Please inspect all freight shipments at delivery before signing. If you see visible damage, note it with the carrier and contact us as soon as possible.

If you need freight, delivery, or lead-time guidance before ordering, contact our team before you purchase.

Compatibility / Fitment

Compatibility varies by product type, machine setup, selected options, and intended application.

For machine-mounted equipment and attachments, buyers should confirm fitment before ordering using the relevant machine information, including model, attachment style, mount type, coupler type, hydraulic requirements, and any other product-specific requirements listed on the page.

Hardscape Heavy can assist with pre-order fitment guidance based on the information you provide. This guidance is limited to purchase and compatibility review before ordering and does not include field installation, hydraulic modification, fabrication, or on-site setup support.

If you are unsure whether a product will work with your machine or application, contact us before placing the order.

Returns & Warranty

Warranty coverage is provided by the product manufacturer where applicable. Warranty terms, coverage periods, exclusions, and claim procedures vary by brand and product type.

Hardscape Heavy does not create separate warranty coverage beyond the manufacturer’s warranty unless explicitly stated on the product page.

Returns are governed by our store return policy. Because many products in this category involve freight shipping, special ordering, or configuration-specific selections, return eligibility may vary by product and condition.

Please review our full return policy before purchase. If you have questions about return eligibility or manufacturer warranty coverage for a specific item, contact us before ordering.

The Mark-IV Dust Buggy cleans out control joints, removes old joint filler, and makes straight, accurate cuts in concrete for repair and decorative work. Paired with Tiger Tooth blades it strips polyurea filler out of joints, which is the job that wears out lesser rigs.

The blade guard covers most of the blade for dust control while still leaving it visible to the operator, which is what makes the cuts accurate. The aluminum alloy chassis carries a lifetime warranty and keeps the machine stable through the cut, the blade depth is fully adjustable with a lock that prevents overcutting, and the current build adds a magnetic switch that eliminates accidental restarts plus a combined voltage and amperage gauge so the operator can load the grinder without burning it out. This is the saw for the joint and decorative concrete contractor who wants clean-out precision on ordinary 115 V site power.

Common Applications

  • Joint clean-out and joint filler removal
  • Decorative concrete cutting
  • Straight repair cuts in concrete slabs

Selection Notes

  • Ships with an 8 in concrete blade; accepts 7 and 8 in blades up to .375 in wide
  • Pair with Tiger Tooth blades for polyurea filler removal
  • Plan dust collection around a 200+ CFM extractor such as the Ultra Vac 1250
