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. Special-order, custom-configured, used, damaged, or installed items may not be eligible for return.

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.

This is the top grade of three U.S. Saws publishes on its small-diameter concrete blade line, and it is a narrower range than the grade below it on purpose. Every size here is a thick section, .250 in or .375 in, which is the width a joint needs when the fill goes back in behind the saw rather than the width for opening a hairline. The grade below runs from .080 in up and covers the thin work; this one starts where that one leaves off.

Eight of the ten sizes are a plain 7/8 in arbor for a grinder or a joint clean-out saw. The other two are built for the CC-100 crack chaser and mount on a 5/8 in bore with a drive pin hole, which is what stops the blade slipping on the arbor when the saw loads up in a deep chase. Those two are the most expensive sizes in the line by a wide margin, and U.S. Saws says why in its own copy: the highest grade of diamond it stocks is what makes them acceptable on that machine.

Common Applications

  • Joint clean-out on concrete ahead of a polyurea or epoxy fill
  • Crack chasing on concrete and masonry
  • Cutting on the U.S. Saws Dust Buggy series joint clean-out saws
  • Crack chasing on the CC-100, on the two sizes built for it

Selection Notes

  • Match the mount to the machine before the diameter: the two 5/8 in crack chaser sizes will not fit a plain 7/8 in arbor and the reverse is also true
  • Both section widths are published at every diameter from 4 in to 6 in; the 8 in is published at .250 in only
  • Two 8 in part numbers share one size and one bore and are priced $4.60 apart, and the only difference U.S. Saws states is which saw each names
  • U.S. Saws publishes no weight that distinguishes one size in this line from another
