Use this mat for vehicle entrances to farm and disease-sensitive premises. The mat is very durable, and will withstand considerable vehicular traffic - even loaded trucks - if driven over carefully. The mat is sufficient length that all tyre sizes will make a full rotation on it. The mat is supplied in two parts that are domed together along the centre line for use. There are stainless steel eyelets in the corners for securing to the roadway if required. The road surface must be smooth under the mat. Asphalt is excellent, chip seal is acceptable if it is fine chip. If the road is coarse chip seal, or plain gravel or sand, it should be covered with plywood under the mat. To use for the first time, prepare about 40 litres of disinfectant solution in 20-litre jerry cans. Pour slowly on each side of the mat. (When the mat is new it can be slow to take in solution.) For subsequent daily or twice-daily refilling, apply 20 litres to each side of the mat, or such amount as required.
