Concrete
Concrete foundation
A compact concrete pad gives a firm ground-mounted platform and can receive the installer-approved anti-vibration feet or frame.
Often worth considering for: Permanent ground units beside houses and plant areas
Specialist base installation
Air Source Heat Pump Bases
A heat-pump base must keep the outdoor unit level while preserving airflow, service access and condensate drainage.

What the foundation needs to do
An air source heat pump is not simply placed wherever a small slab will fit. The outdoor unit needs the clearances, vibration control, fixing arrangement and condensate route stated by its manufacturer and system designer.
JustBases installs the agreed ground base ready for the MCS or competent heat-pump installer, without moving responsibility for the refrigerant, electrical or commissioning 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 purpose-prepared heavy slab or proprietary base may suit some units when the heat-pump supplier accepts it and the sub-base is sound.
Often worth considering for: Smaller domestic units with an approved mounting system
Ground screws
Ground screws and support frame
Ground screws may support an engineered equipment frame where the designer accepts the arrangement and clearances can be maintained.
Often worth considering for: Sloping ground or locations where a raised mount is advantageous
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
The heat-pump designer should select the unit position with noise, airflow, pipe runs and permitted-development rules in mind before the foundation is installed.
We need the exact mounting footprint and condensate detail. Catalogue cabinet dimensions alone do not show the feet, frame or required clearances.
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.

Reviews of our foundation work
"I couldn't recommend Craig highly enough! Communication prior to the job was outstanding even considering our ever changing goal posts. Craig and his team turned up exactly at the agreed time, were well presented, friendly and professional. The cleanliness, attention to detail and quality of the job was outstanding."
"Good standard of workmanship. Friendly and efficient. Prompt response for estimate and fitted into our timescale. Will be using the firm in future and thoroughly recommend 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."
