case study facilities management l
the warehouse included a large number of columns, and around 40% of the aisles were located very close to these columns. This made it difficult to achieve the DIN 15185 specification during the floor construction. If these columns had not been so close to the aisles, only around 30% of the aisles could have been found to be out of this specification, lowering the grinding cost even more.
Ioannis Masoutis, chairman of the board, commented: “The high standards required by D. Masoutis S.A. throughout our operations demanded the construction of an industrial floor of the highest quality. The technical solution offered by the main contractor Vermion S.A. and executed by Eurolit Industrial Flooring in co-operation with Concrete Grinding Ltd fully justified our choice. "The laser grinding process did not interfere at any time with other ongoing works. We had a very strict programme and the whole floor construction and grinding process was completed according to schedule and without any deviation. It also proved cost effective; as the floor was laid to a high standard,
Concrete Grinding Ltd identified areas within the aisles that already complied with the
specification, meaning the
amount of grinding was minimised. "As a result, the operation of our VNA trucks within the 107 aisles
totalling more than 4,500 linear metres of our 50,000m2 facility is flawless.
The trucks operate effortlessly and efficiently at the maximum speed specified by Linde Materials Handling of 9km/h, even with the operator cabin located at the maximum height. "We are extremely pleased with the overall results and highly recommend Eurolit Industrial Flooring and Concrete Grinding Ltd.”
Thanasis Giouletzis, branch manager Northern Greece of Ergotrak S.A. - the official distributor of Linde Materials
Handling in Greece – added: “We confirm that due to the high flatness standards achieved by Eurolit Industrial Flooring and Concrete Grinding Ltd (DIN 15185) of the floor at the new warehouse of D. Masoutis in Kavalari, our VNA fork lift trucks operate at their maximum designed speed of 9km/h regardless of their elevation point.” The new DC was fully operational in September. ●

Concrete matters A
Twintec, a producer of ‘jointless’ steel fibre reinforced concrete (SFRC) floors, is producing a series of Advisory Papers covering a range of subjects. TAP01 focuses on warehouses and storage facilities in the 21st century.
modern 21st century warehouse is a very different place from its predecessor of the 1980s and 1990s. Developments in logistics
technology and software, along with advances in storage systems and mechanical handling equipment (MHE) have allowed manufacturers and distribution companies to become dramatically more efficient. Racking systems are becoming higher, aisles narrower and automated systems commonplace, providing operators with efficient stock retrieval and faster delivery to the customer.
But the higher demands placed on the warehouse and its floor slab are causing building owners to be increasingly aware of maintenance problems associated with traditionally designed and installed floors,
particularly the stress relieving saw-cut joints (planned cracks). As a result, ‘jointless’ industrial flooring systems designed and installed by specialist contractors such as SFRC are becoming more frequently specified and have proven to be a successful solution. A SFRC ‘jointless’ slab is designed to eliminate the need for saw cut induced contraction joints.
Adopting a SFRC ‘jointless’ system will not only minimise the problems identified above, but also improve the flexibility of the building in terms of future-proofing it.
There is a down side to this interesting innovation: the construction of SFRC ‘jointless’ slabs is technically and practically very demanding. When building owners, consulting engineers, architects and general contractors have decided to opt for a ‘jointless’ SFRC slab,
they must take precautions in choosing the right flooring specialist for the job by carefully reviewing the following items: • The flooring specialist's track record in ‘jointless’ SFRC floor slab design, detailing and construction;
• Visit SFRC reference floors and ask the opinion of their users;
• Check the site quality control procedures proposed by the flooring specialist contractor;
• Check the CVs of managers and workers, particularly their expertise with SFRC;
• Ensure early co-ordination with the flooring specialist to optimise design and adjoining interfaces;
• Limit the number of split responsibilities within the contract. To download a full copy of the paper visit Twintec's website. ●
