Complicated repair to occupied warehouse
CG Flooring Systems has recently completed a substantial joint repair project at a warehouse in Milton Keynes occupied by an international quality tyre company
G Flooring Systems was invited to submit a proposal for the repair works by Paragon LLP which acted as project manager on behalf of LaSalle Investment Management and the occupier. The repairs were required on two expansion joints, each of 70 metres in length running the entire width of the warehouse, mainly in Free Movement (FM) Areas including a 35 metre sec- tion through the Very Narrow Aisle (VNA) area of the warehouse. The repair method carried out on both joints by a previous tenant had failed exhibiting signs of poor concrete com- paction around the metal angles, excessive signs of premature wear and degradation once subjected to opera- tional traffic from the customer’s mate- rial handling equipment (MHE). With the emphasis on ensuring the joint repair works could proceed with minimum impact to the customers ongoing operations, the repairs were to take place over four phases treating half the length of each joint at a time. Based on good engineering practice the new repair detail involved cutting back to sound concrete within the existing floor effectively forming a channel. The old and damaged concrete was cut into blocks, which in turn were lifted out and removed for disposal.

This method of removal ensured a vir- tually dust free process without the need for erecting structures to prevent dust from contaminating warehouse stock. The newly formed clean arris edges to the concrete slabs then had holes drilled into them at regular inter- vals, into which dowel bars were resin fixed in order to provide a load trans- fer mechanism to prevent differential vertical movement at the joint, which can be caused by the movement of MHE across the joint. Consolidation of the sub-base, application of a physical damp proof membrane and a layer of reinforcement mesh completed the preparation works. An early strength, micro-silica concrete was then poured into the channel which received a power floated finish.
There were a number of reasons for choosing this repair detail, mainly the use of a concrete mix of this nature ensured the floor could achieve a very high standard of abrasion resistance within a short period and be returned to the customer within seven days of each phase being completed. This compares favourably with a signifi- cantly longer period of 28 days if a standard concrete mix was used. The installation of the load transfer mecha- nism will not only provide better sup- port for daily operations, it has the

very strong potential to reduce future maintenance costs for both MHE and floor repairs.
Completed joint repairs for VNA area or warehouse
This project demanded a considered and measured approach in order to deliver the high standard of repair required, within an acceptable time frame. Each phase was completed over one working week and this could only be achieved by adopting a dynamic approach with clear commu- nication paths and undoubtedly, an understanding warehouse occupier. The appointment of a specialist indus- trial flooring contractor whose knowl- edge and understanding of not only concrete floors, but experience of warehouse operations to work in tandem with a professional project management services and clear com- munication by Paragon LLP, demon- strate the benefits of what can be achieved by using specialist project managers on challenging projects. Richard Estrop MRICS, Partner at Paragon LLP comments: “The proac- tive approach and knowledge of CG Flooring played a key part to success- fully delivering a complicated project in an occupied warehouse. The works were completed to a very high stan- dard and I would not hesitate to rec- ommend CG Flooring for any other floor repair works.” CG Flooring Systems T: 01484 600085

Shelving range acts as add-on to traditional racking systems A
PEX Linvar, the specialist in quality cost-effective racking and shelving solutions for the food pro- cessing, packaging and logistics sector, has introduced Speedcell a new industrial shelving range. SpeedCell is made up of vertical columns made from ‘technical’ textiles, each of which contains multiple shelves. Columns hang from a unique track system mounted at the top of the lower tier of pallet racking, allowing them to slide aside, revealing even more shelf-filled columns.
Speedcell is designed to work as an add-on to tra- ditional racking, transforming the lower floor of pallet racking into a fast hand-picking area. Elimating dead space to the rear of shelving, it utilises flue space and its thinner, reinforced fabric shelves are said to give impressive storage density.
S14 Despite appearing soft and light, the textile shelving
columns are surprisingly strong and hard wearing. They are guaranteed for at least five years, but with correct usage, they could last much longer. Each SpeedCell
column supports a 100kg load and with over 20 columns easily fitting into a standard 2.7m bay of pallet racking.
APEX Linvar has own manufacturing and manage- ment facilities in Milton Keynes, while its Storage Direct Catalogue offers thousands of complementary products. Chief executive Anthony Finlayson-Green says: “The name APEX Linvar is synonymous with quality and that’s why we can list among our impres- sive client base well-known brands including, Tesco, Sainsburys, Argos, Marks & Spencer, River Island, TNT and more.” APEX Linvar T: 01908 561222
