Getting the Ground Ready Before the Frame Arrives
Not every project needs new groundwork, but where existing paving is unsuitable or a freestanding structure needs its own foundations, preparation happens before the main frame is installed. Understanding the typical sequence helps set expectations for how much disruption to expect beforehand.
Assessing what is already there
The starting point is establishing whether existing paving or concrete is sound enough to take new structural loads, which was covered during the survey. Where it is not, some or all of the affected area needs digging out before new foundations go in.
Excavating and forming new pads
Where new pad foundations are needed, this typically involves excavating to an appropriate depth, positioning any required reinforcement, and pouring concrete that then needs time to cure before posts can be safely fixed to it.
Working around existing paving
In many gardens, only the specific post positions need new foundations, meaning the surrounding patio can often be left largely undisturbed, with the new pads later covered or blended with matching paving where possible.

Common questions
Will groundwork make a mess of my whole garden?
Not usually the whole garden, since work is typically concentrated around the specific post positions or foundation footprint rather than the entire plot, though some disruption in that immediate area is normal.
How long does new concrete need to cure before building on it?
Curing time depends on the mix and conditions, and your installer should factor an appropriate gap into the overall schedule rather than rushing straight from pour to frame fixing.
Can I keep my existing patio and just add new pads?
Often yes, where only specific post positions need new foundations, meaning the rest of an existing patio can usually be retained and worked around.
What happens to spoil from the excavation?
This is normally removed by the installation team as part of the project, though it is worth confirming this is included when discussing your quote.
Curing time and its effect on scheduling
Concrete needs adequate time to cure before it can safely carry structural load, which is why groundwork is often scheduled as a distinct earlier stage rather than immediately followed by frame installation on the same visit.
In short
Groundwork is usually concentrated around specific post positions rather than the whole garden, with new concrete needing adequate curing time before the frame goes on.
