What the foundation needs to do
A flag creates a large changing wind load at the top of a slender pole. Foundation size therefore cannot be estimated safely from pole weight alone.
We install the concrete foundation and bolt cage or ground socket to the flagpole supplier's approved schedule, setting hinge direction and finished levels before the concrete cures.
Options, assessed properly
Suitable foundation methods
The methods below are possibilities to assess—not interchangeable specifications. We match the foundation to the product, loads, support points, ground and access.
A written price for the approved detail
Specialist foundations are quoted from the actual product, support plan and site information. No VAT is added to the guide prices shown.
Before installation
Dimensions, approvals and responsibilities
Supply the exact pole, flag and site-exposure data. Foundation tables often change at particular pole heights and between heavy-duty grades.
Planning permission and flags/advertisement controls may apply depending on height, flag type and location. Resolve these before concrete is placed.
JustBases quotes the agreed foundation and groundwork. Product installation, specialist connections, commissioning and third-party design remain outside our scope unless the written quotation expressly includes them.

"Craig and his team were very professional throughout the job. They worked tirelessly and extremely hard. The job involved digging up a thick reinforced concrete base. Then creating a whole new base with precision engineering in preparation to accept a new building on top. The result was an excellent job all round."
