Structure:
The Traverse boulders are handcrafted from specially mixed, 9500 psi, fiberglass reinforced concrete (GFRC). Pumice is added to the mix for weight reduction. The concrete is additionally reinforced by rebar and two integral layers of steel mesh. These small boulders are shipped on a pallet and can be placed on to the prepared concrete pad.
Hairline cracking is natural, and structurally does not in any way affect the structural strength of the piece. These boulders are designed to have a realistic but friendly finish. After sculpting and curing the Traverse boulders are hand finished with an abrasive stone to duplicate natural glacial polishing and weathering.

Holds:
The Traverse line which includes 3 sizes, Small, Medium and Large, are a great introduction to climbing and can be used as stepping stones or paired together to create a boulder field. All include self-draining ledges to eliminate water collection and freeze/thaw cracking.

Finish
The Traverse is hand painted and clear coated for protection from the elements. It is available in sandstone, and granite. The clear coat sealant allows graffiti to be removed easily. However, RockCraft’s experience has been that little or no tagging actually takes place.
Custom sculpting and painting may be provided to match the boulders to the look of your local stone.
