Besides many shops in all kinds of articles it is now also possible to order large batches over the internet. Sand, gravel and soil hereby is one of the possibilities.
Ordering sand is no longer just through trucks and a large pile of sand outside the door. For several years, the so-called big bags ?? ?? on the market that make possible supply of sand in small pockets. The bags are available in different formats but the most common size is the big bag of 1m3 ?? ??. The Big Bags are disposable bags and can be disposed in the housing container after use.
More and more municipalities are not allowed to deposit a large pile of sand, gravel or soil on municipal land. The Big Bags provide a solution here because the sand is delivered packed and this is therefore no clutter and loose sand.
Given the large amounts and the weight of sand can obviously not be transported through the regular transportation. The sand is or transported by truck or lorry on which the Big Bags are sorted. By means of a clip, the Big Bag is delivered for at the street. To be able to order a Big Bag is therefore necessary that the saw can be delivered to a paved road where trucks are allowed.
Before the sand can be ordered, it is necessary to know how much sand you actually need. Sand is calculated in m3, or length x width x height. Then multiply the result again with 1.1. This is necessary because the sand still locks into place.
Filling a sandpit of 2m by 2m. In total, the sandbox is filled with 20cm of sand. At first you calculate the length x width or 4m2. The square footage x 20cm = 0,8m3. As a final step you calculate the subsidence, or 0.8 x 1.1 = 0,88m3. To fill this sandbox you need so 0,88m3.
Sand comes in many species all its own specific characteristics and purposes for which it is used. For example, road sand used under tiling and drainage sand to let the water well.
The type of sand is also expressed in terms of Mu ?? s. The number of mu stands for the grain size. As will be depending on the particle size of sand and clay classified as follows:
gravel: more than 2000 mu;
coarse sand: 200 to 2000 mu;
fine sand: 50 to 200 mu;
loam: 16 to 50 mu;
Sludge: less than 16 mu;
clay: less than 2 mu.
The coarser the sand, the better the water goes back through the sand.
