A small equipment pad provides durable support for proprietary feet or an installer-specified frame.
Often worth considering for: Permanent domestic and light-commercial condenser units
Specialist base installation
Air Conditioning Outdoor Unit Bases
An outdoor AC unit needs a stable mount that keeps the condenser clear of standing water and leaves room for airflow and servicing.

What the foundation needs to do
Outdoor condenser units can become noisy or difficult to maintain if they are left on an uneven or cramped platform. Their feet, pipe entry and required clearances vary between models.
We prepare the agreed ground base for the air-conditioning installer, coordinating levels and condensate or surface drainage without undertaking refrigerant or electrical work.
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.
Paving slabs
Paving-slab base
A heavy-duty proprietary slab or prepared paving base can suit selected units where approved by the installer.
Often worth considering for: Compact condensers in accessible garden positions
Ground screws
Ground screws and support frame
Screws may support a raised equipment frame on a slope, subject to the equipment designer's acceptance and suitable ground.
Often worth considering for: Special locations where a conventional pad is awkward
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
Ask the AC installer to confirm the unit position, mounting system, clearances and condensate route first. Screening added later can obstruct airflow.
Multiple condensers may need a larger coordinated plant area rather than separate improvised slabs.
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."
