Build balcony with ground screws
To build a patio or a deck on a foundation of ground screws do not differ appreciably against when building on a foundation of concrete blocks. The essential difference is that the regulatory framework is based on a number of ground screws is about 1 meter deep into the hill.
The advantages from using ground screws
The advantages from using ground screws is that there is no need for excavation work and so no need to turn the garden upside down as you would when digging by hand or with a small excavator. Installing ground screws is quick and you can put them exactly where the wooden framework is going to sit and at exactly the height you want. Prior to installing the ground screws, holes are pre-drilled to ensure safe and accurate placement. Any rocks up to about 30 cm are broken up, while the smaller ones simply move.
Work can begin immediately the screws are installed.
Different screws for different soil conditions and jobs
We have four different basic screw models. The primary choice when building a deck is to use beam-screws, or possibly post-screws if you want to insert an upright post to cover differences in ground levels beneath the deck. Both beam and post screws are available in different lengths and dimensions so as to cater for varying soil types and load requirements.
When the conditions are not suitable for ground screws on a deck or patio
In most cases a ground screw is an effective and stable method for securing various types of constructions and items that are required to sit fast upon the ground. But there are of course times when a ground screw is not appropriate. This will be the case if there is solid rock where you have to build, and then it is usual to drill holes in the rock and anchor with a steel tie. Or, if you are building partly over solid rock, we can help you put the screws into ground where there is no solid rock and use an anchor or tie where there is.
Another example of when a ground screw is not suitable is if the ground is soft and unstable down to a level of 50 cm or more. Then you need the ground compacted before you can be sure that the structure will be solid and stable. EXTREMELY rocky ground can be a problem, but in most cases we can install the ground screw even in rocky soil as we pre-drill for all the screws, and that then breaks up any rocks up to about 30 cm in diameter.
Other examples of building with ground screws
When it comes to construction in and around a garden, there are many other uses for ground screws. For example:
- • Building fences with ground screws
- • Building a garden shed with ground screws
- • Building larger garden buildings (offices, summerhouses, etc.) with ground screws
Other situations where ground screws can be used to good effect are, for example, the installation of bicycle racks, parking bays, signs, rubbish bins, jetties, play equipment etc.
