Precast concrete paving in the urban landscape: A dissertation submitted as partial fulfilment of the requirements for the Diploma in Landscape Architecture at Lincoln College, University of Canterbury

Abstract

Precast concrete paving units are becoming a popular paving choice in all sectors of the urban landscape, be it domestic, commercial or industrial. Their handIing and installation, and their attractive appearance and durability have resuIted in the increased demand for this type of product throughout New Zealand.

As the basic constituents which make up concrete (cement, aggregate and water) are so abundant and readily obtainable, it is not surprising that this material features as one of the predominant paving surfaces in New ZeaIand. Until more recently this was in the form of in situ concrete, however the growing demand for a precast concrete paving product is changing this and could have a direct effect on the future visual character of the urban landscape.

Bearing this in mind the study has been divided into three parts. Part One sets the scene by reflecting on the traditional use of paving and discusses the reasons for the development of precast concrete Bearing this in mind the study has been divided into three parts . Part One sets the scene by reflecting on the traditional use of paving and discusses the reasons for the development of precast concrete paving in New Zealand. The types of precast concrete paving units available and their manufacture and installation techniques are also described so that a better understanding of the product and its characteristics is obtained before analysing its applicability in a variety of situations. Part Two includes a table showing the range of products available in Christchurch and analyses their use within the domestic, commercial and industrial sectors of the urban landscape. Part Three looks to the future and discusses what direction this form of paving is Iikely to take and how better use can be made of existing products paving in New Zealand.
