Gwynedd Council Waste Treatment Service needed to contain wind blown litter at their Ffridd Rasus site outside Harlech. On windy days when bin wagons were emptying loads, litter was blown onto adjoining properties.
We installed approximately 130m of 7.8m high fencing with an overhanging arm. The netting had apertures small enough to catch all the litter but not cause too much wind loading, allowing the posts to be of a gauge to meet a limited budget. The fence was suspended above an existing 1.8m high fence and designed so it could be moved further down the site once that particular area of tipping had reached the end of its serviceable life.
All posts were specially designed to be bolted down to a concrete foundation and each intermediate post fitted with additional lugs to attach a backstay for added strength. Installation was completed in two visits. First digging and setting the 1m3 concrete foundations, then delivery and installation of almost 8m (26Ft) long posts secured using resin anchors. For cladding the fence an all terrain Mobile Elevating Work Platform (MEWP) was used together with over 900m of 6mm multi strand wire rope and over 9500 plastic ties.
The success of this project has led to the client requesting a further 100m on the same site.
