During the developmental stage of subdivisions, earthworks and civil works leave large areas of ground exposed and subject to wind erosion for long periods of time. Subdivisions are usually located close to other, already occupied residential areas. Airborne dust quickly becomes a nuisance and can lead to complaints from neighbours. Whilst spraying water from a water truck will reduce dust it is not effective for long periods of time. DustBloc is not only far more effective than water it needs to be applied far less often, reducing labour and site traffic. DustBloc is also highly effective for use when the site will be shut down for extended periods negating the need for water truck visits during shutdown periods.
