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.

IMER's Gerris 800 is a self-propelled, tracked concrete placing boom built to distribute pumped concrete anywhere within a 26 ft reach and up to 37 ft of height, for crews placing concrete in tight or multi-level sites where running pipe by hand is not practical. Four self-leveling outriggers set it up on uneven terrain, expandable tracks add stability once positioned, and the three-section boom folds down small enough to pass through a standard doorway despite its reach.

Both configurations are the same machine above the power pack: one hydraulic three-section boom carrying a 4-inch heavy-duty pipe to a 4-inch flex hose at the working end, pairing directly with any concrete pump using 4-inch HD fittings, positioned by a wireless remote controller that comes as standard. What the buyer is choosing is what drives the hydraulics. The bi-energy build runs a Honda GX390 with electric start and carries a 120V auxiliary motor beside it, so the same unit works outdoors on gasoline and switches to shore power when it is taken inside. The lithium build has no combustion engine on board at all, which removes the question of ventilation entirely rather than managing it, and IMER rates its battery pack for a full work day. Where a site bars engine exhaust outright, the lithium is the configuration that qualifies; where it does not, the bi-energy build does the same placing work for less money.

Common Applications

  • Placing pumped concrete at height or in hard-to-reach positions on a jobsite
  • Working in enclosed spaces, on the auxiliary 120V motor or on lithium battery power

Selection Notes

  • Bi-energy runs on gasoline outdoors and on a 120V auxiliary motor indoors; lithium carries no gas engine at all
  • Pairs directly with any concrete pump using 4-inch HD fittings; the boom does not pump concrete on its own
