<p>In order to provide a form of foundation on which light-weight shuttering may be erected prior to pouring the concrete into the foundation, there is provided a method of forming a foundation for an excavated construction, comprising excavating to a predetermined depth, arranging pre-formed footing elements (2) in a required configuration on the base of the excavation (1), the said footing elements (2) having upper surfaces with means for locating shuttering (3, 4) for walls to be erected on the foundation, the footing elements also being adapted to receive reinforcing bars (5, 5a) for the foundation and/or the walls, and subsequently pouring a concrete mix into the excavation to bond substantially monolithically with the footing elements. The footing elements need considerable strength, and they are preferably pre-formed in an open construction of concrete or a light-weight aggregate. The invention further includes footing elements as set forth above, and foundations made by the method.</p> |
