Grass Paver Molds: Open Cells, Ribs and Trial Checks

Author：HAWEN Block Mould Manufacturer TIME：2026-10-11

Grass pavers combine a concrete framework with openings intended for grass or another specified infill. Their molds must reproduce both the external outline and the open-cell pattern. Before ordering, define the finished paver, the intended landscape use and the required production method. A generic hollow block mold is not a substitute for a grass paver mold, even though both products contain visible openings.

Dimension the cells and ribs

Provide the overall length, width and thickness together with the shape and position of every opening. Dimension the concrete ribs between the cells and the outer edges. If an open-area ratio is part of the product requirement, have it checked from the approved geometry. Include edge connections and spacers where used. Common grid patterns may look similar while differing in cell size, rib thickness and mating details.

Review filling and demolding

The concrete must form continuous ribs around the openings. Discuss how the selected mix and machine feed the proposed cavity arrangement, and review the matching core and tamper components. The tooling should be checked for alignment and for access during cleaning. Pay particular attention to the narrower ribs and intersections when inspecting trial pavers, since these areas need to retain their shape through release and handling.

Keep the landscape system in view

Approve a sample panel with the intended infill and joint arrangement. Suitability for parking, access routes or pedestrian areas must be established for the complete installed system, including support layers and maintenance. Open cells alone do not prove drainage capacity or a load rating. Treat product testing and installation design as separate requirements alongside the mold specification, and retain the accepted unit drawing for future replacement orders.

Prepare a practical inquiry

Bring the following information into the first technical discussion. A clear product brief helps the supplier review the proposed configuration and identify the details that need confirmation.

Overall dimensions and detailed open-cell pattern.
Rib widths, edge details and specified open-area requirement.
Intended infill and landscape application.
Machine model, pallet size and trial-sample acceptance points.

Does a grass paver mold guarantee drainage performance?

No. Water movement depends on the finished product, infill, supporting layers and site conditions. Evaluate the intended installed system separately.

Contact HAWEN with your product drawings, machine information and production objectives. The next step is a review of the proposed configuration, followed by a quotation based on the confirmed technical requirements.
