Size/Weight Conversion

To calculate cubic volume simply multiply length by breath by depth.

To convert cubic volume to tonnage the general rule is:
Sand and Soils multiply by 1.3
Pebbles and heavy products multiply by 1.8

Product Units

Sand, soils, pebbles and all heavy products are sold by the tonne (weight), whereas all mulches, composts, barks and litter products are sold by the cubic metre (volume). So when ordering heavy products sold by the tonne, use the Size/Weight Conversion rule to estimate the number of tonnes per cubic metre.


Pebbles are an expensive product and we think it is vital that you get the most out of your order. When using pebbles as a decorative cover always allow at least 2.5 times the diameter of the pebble you are using for the depth of pebble cover, e.g. for 20mm depth use a 0.050mm pebble. Also if you have a great depth to fill use a cheaper product to fill the majority of the depth, e.g. blue meal or river sand.

Mixing different pebble colours or sizes together will allow your garden to make a greater visual impact. The use of other rocks/stones types in your pebbled area can also act as a feature.


When laying new turf always lay a bed or good soil first. This provides the new grass roots with easy downward growth, securing a good water and nutrient supply for the grass. Never make the bed soil too sandy, this will slow down the water loss. If you have a clay soil add gypsum. It is always a good idea to check the soil pH before laying new turf. A pH around 6-6.5 is optimal for growth. 

Garden Soil

When filling your new garden bed or when topping up existing beds always order slightly more than the raw cubic measurement to allow for settling of the soil. Also, when planting natives make sure they sit above natural ground level as this will prevent a number of root diseases.


Decorative mulches can improve the look of your garden. Before you select your ideal mulch however, it is worth investing some time to improve the quality of your soil. We recommend using some compost such as cow manure, mushroom compost, forest floor or leaf mulch. This will improve the soil condition and further help with water retention. You can then add the surface cover of your choice.


Always water your gardens and lawns heavily once or twice a week to encourage your plants to grow deep root systems. This helps them to become more drought resitant.


DIY constructions can raise a number of questions. Feel welcome to visit Menai Sand & Soil and we will be only too glad to set you in the right direction. If the construction is difficult or too large a job for you to handle we can recommend a number of reliable and trustworthy contractors. We even have a comprehensive list of designers.
