Drainage, Civil & Environmental
Durability, strength and appearance factors determine the suitability of precast for a variety of civil, environmental and drainage products including noise walls, culverts, pollutant traps and street furniture.
The requirements for landscaping and municipal products are functionality, durability and aesthetics. All three of these can be met by using precast concrete. There is no limit to the types of municipal and landscaping products which traditionally are supplied in precast instead of insitu, with the added features of precision-moulded products and wide range of colours and textures.
The introduction of precast concrete drainage pits and associated products into the market in the early 1980s, revolutionised the industry by making the installation of pits much simpler and substantially reducing construction times. Previously, all drainage and junction pits had been built insitu. Precast pits not only reduce the installation time, but minimise the problems associated with wet weather. Today, precast pits are accepted by most local government and state road authorities as alternatives to insitu construction.
Precast concrete wall systems to control traffic noise are used extensively on road projects in Australia. Design options include panels curved in two directions, a wide range of surface textures, colours and sculptured surfaces.
