All of our buildings require a concrete base as a foundation.
The base must be flat, square and level. It will ideally be slightly higher than the surrounding area so water cannot settle at the bottom of the garage wall panels.
The concrete base itself should be a minimum of 100mm (4”) in depth, and be 150mm (6”) longer and wider than the external size of the building. Please note that if your building has brick fronts then the overall length of the building will be between 2 and 4” longer.
In order to ensure that your base is square, measure out a 3-4-5 triangle before securing the shuttering prior to concreting.
To check that the base is square, measure the diagonals of the base. Both measurements should be the same.
