The Ascender is hand-crafted from specially mixed, 9500 psi, fibreglass 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. A lifting eye is located at the center balance point for moving and shipping.
Hairline cracking is natural and structurally does not in any way affect the structural strength of the piece. The boulder is designed to have a realistic but friendly finish. After sculpting and curing the Ascender is hand finished with an abraisive stone to duplicate natural glacial polishing and weathering.
The Ascender’s holds are all self-draining to eliminate water collection and freeze/thaw cracking.
The Ascender is hand painted and clear coated for protection from the elements. It is available in sandstone, granite and quartzite colors. 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 Ascender to the look of your local stone.
