A suitable base is essential for the correct installation, performance, and longevity of your Tiger building. If a building is installed on an insufficient or unsuitable base, it can lead to a range of issues over time.
This article explains why a proper base is important and what can happen if base requirements are not met.
Why a proper base matters
All Tiger buildings must be installed on a base that is:
Firm
Flat
Level
Durable
Able to support the full weight of the building
A correctly prepared base ensures the building remains stable, weather-resistant, and aligned as intended.
Common problems caused by an insufficient base
If a building is installed on an uneven, soft, or unsuitable surface, the following issues may occur:
Doors and windows not aligning correctly
Doors may stick, drop, or fail to close properly
Locks may become difficult to operate
Windows may not sit squarely in their frames
These issues are often caused by the building settling unevenly over time.
Gaps and water ingress
Gaps can appear between panels or logs
Roof lines may become uneven
Water may enter through joints or around doors and windows
Even a small amount of movement in the base can affect weatherproofing.
Structural movement or distortion
Floors may dip or flex
Walls may twist or lean
Roof sections may no longer sit correctly
This can place stress on fixings and joints, reducing the lifespan of the building.
Increased wear and maintenance
Timber movement can increase
Components may loosen more quickly
Ongoing adjustments may be required
Over time, this can lead to avoidable repairs or replacements.
Impact on warranty and aftercare
Installing a building on an insufficient base may affect warranty support.
If issues arise that are caused by:
An uneven base
Inadequate support
Ground movement
Installation on grass, soil, or soft ground
…these may not be covered under the product warranty.
This is because the building has not been installed in line with the required installation guidance.
What is considered a suitable base?
Suitable base options typically include:
Concrete slabs
Paving slabs laid on a solid sub-base
A properly installed timber base
A purpose-built plastic or eco base (where appropriate for the building size)
The base must be:
Completely level in all directions
Larger than or equal to the footprint of the building
Fully supported across the entire floor area
Before you install your building
Before installation, we strongly recommend:
Checking the base is level using a spirit level
Confirming the base is firm and stable
Addressing any slopes or soft areas in advance
Taking the time to prepare a proper base will help ensure your building performs as intended for years to come.
