A proper portabase allows airflow to the floor, extending the life of your building. It also helps water to run off the side of your building, keeping the floor dry. Another benefit is that the floor is strengthened, avoiding ‘bounce’. Rodents are also kept at bay because they do not like the larger gap under your building.


  • Gives the floor proper airflow
  • Allows water to run off the ‘skirt’ of the shed
  • Gives the floor extra strength
