How to lay concrete cobbles
When laying cobblestone pavers or cobbles, you should perhaps consider the following factors.
Guidelines
The following guidelines are recommended as the correct way to install wet cast cobble paving
products. C.E.L. Paving as manufacturers do not provide an installation service, nor can the company be held responsible for any defects which may arise from incorrect installation by contractors or clients. We therefore stress the importance of only using experienced installers and contractors. Refrain from using installers
who are unfamiliar with or inexperienced at laying cobblestone paving or any wet cast concrete pavers.
All installations are done at the users own risk.
Storage and Handling
All Cobbles must be handled with care to avoid damaging the edges and surfaces of the product. Cobbles are delivered to site shrink-wrapped to prevent damage. On delivery it is important that stacks are placed on level and stable ground. Once goods have been offloaded on site it is very important that cobbles are taken
randomly from various pallets to ensure good colour distribution between the various batches. Offloading of the Cobbles on site should always be handled with care to avoid breakages and chipping of the product prior to laying. Cobbles are heavy and bulky, so suitable lifting and handling equipment should be used. The correct safety gear and protective clothing must be worn at all times including gloves, dust masks, and safety boots.
Preparation for laying cobblestones
Before bringing in the Cobble concrete block paving, remove approx.100mm of ground, making it lower than the required finished level of the paving for commercial use. Ensure that the bedding sand is free of
roots and clay and other inperferfections, prior to compaction. A 20mm-50mm topping of clean white
builders sand (sharp sand) is then compacted and prepared for the screed (thickness to be decided by installer/contractor). For high traffic, steep or inclined driveways or roadways we recommend that the topping and screed be a mix of 10:1 sand and cement to give added stability to the base.
The screed consists of a layer of slightly damp sharp sand 20mm-40mm thick. The total thickness of topping and screed is not to exceed 50mm-60mm unless cement stabilized).String lines and a straight edge are needed to level and get the correct falls and finished heights. The area is now ready to be paved with the concrete block cobbles.
