Lime/Cement Stabilisation In-situ soil stabilisation is used throughout the building and civil engineering industries. This is a quick and cost efficient method cheaper to modify existing soils with binders such as lime and cement to create pavement and ground slab foundations, than the traditional method of disposal and import of materials to profile a construction site. Most cohesive and granular sub - soils can be stabilised. Natural soils as well as made ground and recycled materials can be utilised. Stabilisation eliminates the removal of unstable or unsuitable material from the site, such as soft clay or wet sands and gravels, utilising materials onsite to stop import and export of material. Instead the soil is can be treated with lime/cement to increase strengths, reduce MCV’s required for structural fill and capping/sub-base layers dramatically reducing the requirements for stone.
Cement stabilisation (HBM) Reeds have developed methods of hydraulically binding existing or imported granular material to act as hard standing areas, recycling yards, haul roads etc. With the use of binder materials a slab can be created with very high durability, fibres can be added if required for extra strength leaving a re-enforced concrete slab up to 300mm thick. Once the process is completed the material is trimmed, compacted and power floated to leave a solid, sealed, impermeable surface.
Cement stabilisation of solar farm roads Reeds are able to use HBM methods to stabilise existing onsite material to give quick cost efficient and long lasting roads for access and long term maintenance on PV farms. Material and ground conditions are tested for suitability and a road design is created. Natural material is treated with binders to a depth of 300mm and stone is imported to act as a running course, this in turn is treated back into the below treated layer to give a strong wear resistant slab. This method has been proven on various projects over the UK.
Stehr compaction systems are flexible to use and adapt to many difficult compaction problems. The Stehr-compressor disks do not have a feed, but are towed or pushed by the carrier. This means that the force generated by the two counter-rotating eccentric shafts is directed vertical to 100%; this results in a much higher compression efficiency than conventional vibratory plates, and a lower risk of vibration affecting rails, footings and other areas of risk surrounding the working site. See the comparison in the video above between the Stehr compactor plates and a conventional roller against a cup of water!
Stehr Compaction Control SCC This plate compactor meter is included with all plates.
The electronic meter displays the compaction results and frequency to the user in a simple way on a clear display. This can avoid unnecessary or too slow crossings, since the operator can always optimally adapt the driving speed of the compaction result, ensuring huge savings. There are fewer pollutants and CO sup2 generated.
