Pool Construction Tips

Hi, I'm Mandy. If you're looking for tips on pool construction, you've come to the right place. We've just had a new pool installed and I'm full of advice! When I started on our pool I thought it would be an easy build. Boy, was I wrong. I didn't know anything about building a pool apart from the fact I wanted one. Luckily, our construction company set me straight. They helped me work out how big the pool could be and they showed me which shape would suit our yard space. They sorted out permits and even gave me advice on fencing. To find out what I learned, read through my blog. Hope it helps!

Pool Construction Tips

Two situations in which you should use non-destructive digging techniques

by Bessie Beck

If you need to have construction work done on your property that will involve digging and you're in one of these situations, you should request that your contractor use non-destructive digging methods (such as using suction or pressurised water to dislodge the soil, instead of digging it up with an excavator).

The digging area is close to a protected tree

If you have a protected tree on your property that the law prohibits you from damaging or removing and your construction project will involve digging up soil that is near this tree, you should ensure that the contractor and their team use non-destructive digging techniques to remove this soil. Whilst the tree itself might not be directly within the area that you intend to dig, its roots (which, if it's a fully grown tree, could be several metres long) might be. If your contractor were to dig up the soil mechanically with a standard excavator, there is a chance that this excavator's bucket could cut and damage some of the protected tree's roots. Because the roots of a tree help to transport nourishment to the other parts of it, damage to them can result in damage to the entire tree.

Conversely, if the soil is removed from this area using, for example, suction equipment, that can remove the soil in a more controlled manner using a relatively narrow suction tool that doesn't have the sharp edges that an excavator's bucket does, and that won't subject the soil and the roots or debris that's within it to any forceful impact like an excavator would, the chances of the digging process leading to the destruction of the protected tree's roots will be negligible.

You need to dig in an area where you know there are underground utility lines

Another situation in which this form of digging might be needed is if you have to dig in an area of your property where you know that there are underground utility lines, such as water pipes or electric cables. In this situation, breaking through the soil with a heavy excavator bucket could lead to the breaking of these utility lines, which could then cause many issues.

For example, if the excavator hits a water pipe and breaks it, this could completely saturate the soil in the area you're working in. The saturated ground could become too unstable to stand on or park the excavator on and could be harder to scoop up due to its muddy, watery composition. Additionally, your property's water supply might be affected until the pipe is fixed, which could take quite a while. If however, your contractor was to use a specialised suction tool for this task, there would be no possibility of them hitting and damaging this water pipe; instead, the soil would be drawn up from the ground in a relatively gentle manner.
