Concrete Grinding Ltd has successfully completed its largest ever floor grinding (in linear metres) for a global glassware company in Italy.
Italian job T
he client’s new DC floor was originally built by a flooring contractor using laser screed construction to meet with DIN 18202 floor flatness
specification. Whilst the racking was being installed, Trimmer S.r.l Profileograph surveyed sample aisles and found they all failed to meet DIN 15185, the required floor flatness standard for VNA operation. Trimmer contacted Concrete Grinding Ltd, whom it represents in Italy, and Concrete Grinding was then commissioned to grind the aisles to tolerance.
The very busy and operational warehouse facility consisted of 64 aisles, which were split into seven different compartments, totalling just over 5,700m. Before corrective work commenced, Trimmer surveyed the remaining aisles; Concrete Grinding analysed the data and identified that only 80% of the total aisle length required remedial grinding. As Concrete Grinding is the only
superflat floor grinding specialist in the industry that could laser grind exact areas out of specification rather than the whole aisle, the client
commissioned Concrete Grinding to grind the aisles to specification. This also benefited the client as precise corrective grinding provided a cost- saving solution.
To meet with the client’s deadlines, Concrete Grinding operated two laser grinders and carried out two-wheel track grinding x 400mm cut paths on 4,570m of aisles. The facility operates BT (Toyota) four-wheel fork lift trucks where the wheels fit perfectly within the 400mm cut path. The grinding was executed on a five-aisle rolling programme so that the client’s warehouse operation could continue to function as normal.
Concrete Grinding was also asked to carry out floor joint repairs in the facility. With assistance from CG Flooring Systems Ltd, the team carried out 110m of joint arris repairs and 1,200m of joint reseal repairs within the 400mm ground path to cater for the wheels of the trucks. This resulted in an
additional cost saving as the whole aisle width did not have to be
repaired.The saw cut joints were resealed every four metres along each aisle. Fifty metres of joint repairs were also completed within door openings between the seven separate compartments.A large portion of the joint repairs were completed immediately after Christmas, during the client’s shutdown, ahead of grinding work. After grinding, Trimmer re- surveyed the aisles using the FACE DIN Profileograph to prove the floor flatness specification had been met.
The client's managing director and project manager were involved in the project. They were very happy with the work Concrete Grinding and Trimmer had carried out, saying: “We were very impressed with the quality of Concrete Grinding’s and Trimmer’s work and commitment to the project. The laser grinding work did not interfere at any time with our busy warehouse operation. We also had a very strict time table and the grinding and repair work went according to schedule. “We chose Concrete Grinding because of their precision laser grinding system and their flexible approach to our requirements. We are extremely pleased with the overall results.” ●
