Gramm Barrier Systems can offer guidance and supervision in the complete barrier construction process to ensure that all British and European standards are met in full including CE Marking under CPR 2013.
With the increase of traffic on our major highways and the rising level of public complaint, noise barriers, properly designed, still provide the most effective and long lasting solution to highway noise.
Brownfield sites close to motorways are being increasingly used for new large-scale housing developments. The impact of traffic and onsite construction noise can greatly affect the value of the built homes. Relying on low-level basic wooden fences for noise insulation can leave the properties virtually un-sellable.
Gramm Barrier systems offer a full design service from start to finish. We will work out wind loadings on the system, Foundation and post sizes plus barrier types best suited for your location. i.e Timber Reflective, Metal Absorptive. Once we have worked out a guaranteed design we will produce full design calculations, Drawings + certificates.
By measuring noise level variations throughout the day, and by assessing the background level and frequency spectrum we are able to find out just how intrusive the noise really is.
Computer modelling enables us to predict how the noise spreads from the road or factory to the surroundings. Taking into account topographical features, weather and ground conditions, we can build up a clear picture of where noise reduction is most needed.
Using the model, we calculate the optimum design of barrier for the job. We “tune” the barrier to the noise to give the most cost-effective solution and provide a comprehensive design specification in terms of type, performance, dimensions, structure to satisfy local environmental and planning requirements.
