Supply and install "monotec" wire mesh baskets
Supply and install wire mesh baskets with fill of frost and weather resistant stone material. The containers consist of electric spot-welded steel wire screen mats, held all round with welded eyes.
The tensile strength of the eyes corresponds to that of the wire tensile strength. The basket manufacturers are certified in accordance with ISO 9001. The individual parts are fitted together in-situ, using push fasteners, to form containers in accordance with the manufacturer's instructions, the cavity filled, and then closed.
All verifications are to be carried out before the contract is awarded. Earthworks are separately accounted.
