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.

The P800 is the largest grinder National builds and the one for open floors with no service to plug into. It pairs the 32 in head of the M800 with a propane engine, so a warehouse shell, a new slab or an outdoor deck gets the same coverage per pass as the electric machine.

Its emissions monitoring is the feature that decides whether the machine can be used indoors at all. EcoSense watches the exhaust and shuts the engine down automatically when levels run too high, which turns an operational risk that depends on someone noticing into a machine behaviour that does not.

Handling follows the M800. Automatic planetary lifting raises the head for transport, a third wheel carries the frame during loading, and the transmission is fully geared rather than belt driven, which removes the belt service interval on a machine putting engine torque through the drive.

Common Applications

  • Large-area concrete grinding and polishing without an electrical supply
  • Warehouse shells, new slabs and outdoor decks
  • High-output surface preparation on propane in enclosed space

Selection Notes

  • Propane engine with automatic emissions shutdown
  • Step to the M800 for the same head size on 230 V three phase
  • Ships with Fast Change and Wedge tooling plates
