Excavation is a big branch of the construction industry. If you’re performing any major landscaping on your property, or if you’re laying any type of new cable in your garden, you might find a need to have it excavated, as it includes both filling and digging various kinds of openings in the ground. Hiring a contractor to perform it is always the safest way to go, but if it’s not a too complicated kind of project, you can perform it yourself. You do, however, need to know how to take the proper safety precautions.
Involvement by authorities
The first thing you need to know is that you won’t be able to avoid involvement from any authorities completely. You need to know about what’s under the ground in your garden. It’s important to know exactly where all electrical cords and water pipes run; digging into them could cause destruction, but also produce large fines. You also shouldn’t try to perform excavation if it involves deep openings, or if you need to construct any particularly complicated retaining walls. If it does, you should most certainly get in touch with an expert.
Stabilise the structure and make sure it doesn’t break even after the work is done
When you perform the excavation, you should try to stabilise the cavity as you go along. Even if you’re not digging particularly deep, it can still cause you to get injured if it were to collapse. Also protect the edges of the cavity with some sort of barrier so that people around you won’t accidentally fall into the hole. Your barriers should be sturdy enough to not break if someone runs into them. Regarding the edges of the hole, you should also make sure they’re free from vegetation before you start digging. Roots penetrating the walls of the cavity could seriously destabilize the structure and also ruin your retaining walls when the excavation is done and the roots are allowed to keep growing.
Make sure you’re also providing proper drainage for the excavation, and protect the work when it’s raining. Water getting in to the structure can undermine your retaining walls, especially if you’re using concrete. If the retaining walls were to crack and become porous, you will have to do all the work all over again. But what is more complicated is that you will also have to destruct any existing, malfunctioning structures. This will lead to you spending an excessive amount of money on a project you took on to save money in the first place.
If you feel you cannot accomplish these things during excavations, it would be better and safer to involve a professional contractor.
