| Notes |
| Lines 3,4 and 5 | The sizes and percentages are nominal. By the nature of these products, it is not practically possible to be exact and there might be a small variation. |
| Line 6 | pH is measured using the ADAS method. |
| Line 9 | This is the minimum effective spreading depth after settlement for the product to function adequately.For improved effect, the depth could be increased. |
| Line 10 | This is the minimum reduction in product depth 30 days after laying. |
| Line 11 | These figures are taken from our practical experience. The life expectancy of all mulches depends on the grade, the original spreading depth prior soil preparation, and subsequent topping-up and maintenance together with frequency of use. |
| Line 12 | These products have been independently tested by WIRA Testing Centre for fire resistance, according to BS 4790:1987 |
| Line 14 | These products are pest, disease and weed free, and have not been treated with methyl-bromide or any additive, colorants or dyes. |
| Lines 14-21 |
|
| Line 22 | The guidance costs have been calculated assuming a full articulated trailer load of material was delivered to site, within half a days driving distance from one of our processing depots.Due allowance has been made for the minimum settlement factors as stated in line 9. The cost per m² have been calculated using the following formula :- Product cost delivered to site per m³ ÷ [ ( minimum spreading depth + minimum settlement depth ) ÷ walk surface life in years ]
