Building Structure and a Method of Forming a Building Structure

Abstract

A building structure comprising a footing (21b), wherein the footing (21b) includes a channel (23), and at least one panel (24), wherein the panel (24) is located within said channel (23), wherein the footing (21b) is disposed on a waterproofing membrane (22) which membrane extends along side walls of the footing (21b) and into said channel (23) and wherein the panel (24) has an external waterproofing membrane (25) that is in waterproof engagement with the membrane of the footing (21b) in the channel (23) and wherein the waterproofing membranes (22, 25) comprise an absorptive clay disposed between water permeable layers.

Description

TECHNICAL FIELD [0001] The present invention relates to a building structure and to a method of forming a building structure, in particular to a building structure and method that provides improved waterproofing properties in the building structure. BACKGROUND ART [0002] Larger structures which are built on inground foundations are notoriously difficult to waterproof and current procedures that are used to provide waterproofing require peripheral excavation which are time consuming and costly and depending on site conditions, may restrict economic use of a site. [0003] In addition, excavations for inground foundations often are made at or below the water table which increases the need or an efficient means of waterproofing same. [0004] We have now found a building structure and a method of forming a building structure which increases land use efficiencies and provides improved waterproofing. [0005] Further objects and advantages of the present invention will become apparent from the...

AI Technical Summary

Benefits of technology

[0027] Advantageously we have found that by the use of the building structure of the present invention, the need to over-excavate is substantially reduced or eliminated as there is no longer a requirement to access the external side of the wall as the panels may be placed in situ with the waterproofing membrane in place. As such, it is possible to allow for the maximum utilisation of the building site as there is no need to allow space for the over-excavation of the walls.

[0028] As a result of the use of the building structure of the present invention a dramatic reduction in the construction program for the basement work may be achieved. We have found that up to 50% of the work required to construct the basement of a building structure may be saved. In addition, the requirement for a variety of trades may be reduced or eliminated. We have found that it is possible to reduce or eliminate the need for concreters, form workers, steel fixers and waterproofers.

[0029] The building structure of the present invention may be produced in a manner which permits the saving of a variety of other services such as water, electricity, cranage and the like. In addition the need for onsite storage and accommodation may be reduced.
