6 Steps to the perfect driveway
Firstly we do a driveway site survey using a Cable Avoiding Tool to locate electricity, gas, water, phone lines services. We then set level pegs to ensure the surface area is dug out to the correct depth of 225mm. This allows for the paving blocks, bedding and the sub-base. If there are any soft spots they are filled and compacted. Any remaining weeds or debris are removed. We lay a geotextile membrane to keep the sub-base in one solid layer and to avoid any weeds and roots appearing in the future.
Next we lay the sub-base which is the main load bearing layer of the driveway. We use good quality materials, which are compacted in layers by going over several times. Good preparation is the key to a good driveway.
After laying any necessary driveway drainage, we then start laying the bedding layer. Again using the best quality materials is the key to a good driveway. We use around 40mm of course grit sand and not building sand (like some other companies) as the sand will get washed out in the winter and cause movement of the blocks. The nice flat surface is achieved by setting stainless steel rods and scrapping off the very top layer of grit with a length of timber. We are now ready to lay the paving blocks.
Having already decided upon the design of the driveway with the client we then start to lay the paving blocks. Just like tiling, blocks are used from different packs to ensure any variation in shade is spread over the whole driveway. Patterns are added after the initial lay of blocks to ensure the design is just where you want it to be. When all the full blocks have been laid the edging is set out. These are sometimes a different colour or style, which can add a decorative frame to the driveway. We then have the laborious task of cutting in all the part blocks. Each block is cut at just the right angle to ensure a tight fit. Drain covers can be fitted with a special tray to hold the paving blocks which give a great, unbroken effect. The tray can be removed for access to the drain cover. It is these finishing touches which make our drives stand out from the crowd.
We then concrete the edging to avoid sideways movement. By doing this the edges are strong enough to cope with the weight of vehicles and they therefore protect the rest of the driveway.
We are now ready for the driveway finishing touches. Before we use the vibrating plate to compact the paving blocks, the whole area is checked and we replace any blocks that may be chipped or cracked. We then compact the paving using a vibrating plate with a rubber mat. After that, dry kiln sand is brushed into the joints to create a finished result.
