Edging is important where disabled access is intended. To curve edge-rails make sawcuts % way through at app. 100mm intervals. NOTE: For a trim appearance it is essential that the boards at the bend are out to an even taper - use a line and peg to make it thus:- Drawing exaggerated forclarity NOT TO SCALE ©C.C.S revised 1989 offcut COMPLETE BOARD PLAN Isometric View To maintain a regular curve use the stake and line as compasses to position the outer ends of the boards. Countryside Commission for Scotland Battleby, Redgorton, Perth PHI 3EW Telephone: (0738) 27921, Fax: (0738) 30583 Edge rail shown 6.9 N o t e s 1A board-walk is an obtrusive element in the landscape, and should be used selectively. They can add interest to wildlife interpretation by allowing close access to interesting vegetation. The use of curved runs adds interest and enables the board-walk to be fitted into natural uneven terrain. They are most useful for the protection of fragile areas to which controlled access is required, and provide a smooth, firm surface for wheelchair users. If used as ramps, the maximum gradient should not exceed 1:12, but 1:20 is better. 2Surface coatings or pressure treated timber should not be used where subsequent damage to adjacent wildlife may occur. This is specially important in Sites of Special Scientific Interest. In such cases use larch for ground/water contact members and check regularly for rot. FINISHES 3Subject to note 2 above, all timber should be pressure-treated against fungal rot. For a non-slip surface spray boards with hot tar and dust with grit, or fix chicken wire to surface, using galvanised staples.
