METHOD FOR FORMING A BUILDING FOUNDATION, BUILDING FOUNDATION, SYSTEM, SPACER, CONNECTOR AND INSULATING BLOCK

摘要

Various methods and systems for forming insulating building foundations are disclosed. The methods and systems are for use with fibre-reinforced concrete and allow increased speed and ease of construction because conventional reinforcement is not required. In one embodiment, a method of forming a building foundation comprises: preparing an area of the foundation to substantially the same level; providing shuttering around the outer perimeter of the prepared area of the foundation; arranging at least a plurality of first insulating elements and a plurality of second insulating elements abutting each other within the shuttering to form a continuous layer having a flat lower surface over the prepared area of the foundation, wherein the first insulating elements have a first height and the second insulating elements have a second height which is less than the first height; connecting the plurality of first insulating elements and the plurality of second insulating elements to each other using a plurality of connectors; and pouring fibre-reinforced concrete within the shuttering. The insulating elements are connected to each other using connectors and therefore any tendency of the insulating elements to float during pouring of fibre-reinforced concrete is reduced. Other embodiments relate to the features of the insulating elements and connectors for use in forming insulating building foundations using fibre-reinforced concrete.
