ALEESCO recognize the importance of quality control, and have built up a Technical Department to provide full coverage of all quality aspects. The department is staffed by a qualified Engineer, who oversees all the testing for the Company. ALEESCO obtained ISO9001 certification many years ago, and strives towards continual improvement, through implementation of properly thought out and conceived procedures. Our central laboratory is equipped with all the necessary equipment to handle virtually all raw material tests, with highly trained laboratory personnel, to carry the tests out in accordance with the Company Inspection and Test Plan (ITP). This ensures that only high quality materials are used in the production of ready mixed concrete. Our satellite facilities have plant laboratories, equipped and staffed to carry out in process tests on the concrete prior to delivery to the customer, and can when required provide site technical staff to assist the contractor in monitoring the concrete on arrival at site. All testing is documented, so that a huge data base on all ALEESCO mix design performance is maintained
HOT WEATHER CONCRETING
To facilitate temperature requirements during hot weather, Aleesco batching plants are all equipped with water chillers, and our main depot has ice making plants, to deal with extreme temperatures. All ice is weighed and combined with the chilled water, to maintain the design w/c ratio of the concrete, ensuring that quality is not compromised
Aleesco has a fully equipped workshop, including turning machines and lathes, to provide a full maintenance and servicing program for our extensive fleet of vehicles, and fixed plant. Records of all servicing and repairs are maintained by the Workshop. The Workshop is managed by a qualified Engineer, and all maintenance staff are trained in their specialized discipline.
