20.06.2016 - How to lay Block Paving
First impressions count!
Block paved path and driveways can add a real ‘WOW’ factor to your property. With all the right tools and advice, you can tackle this project as easy as the professionals.
7 Easy Steps How to…….
1. Design – Draw up a layout that suits your need, taking in to consideration the block shape, colour and finish. This will help make estimates on materials required.
2. Excavation – Mark the areas to be excavated. Dig down 240mm for the sub-base, screeding and paving, ensuring the finished level is 150mm below the damp proof course of any adjoining building. Create a slight slope of 1:40 fall (width) and 1:80 (length) of the driveway to allow for drainage.
3. Edge Restraints – Lay Concrete foundation, 100mm thick of 6 parts Ballast and 1 part Cement. Install the Kerb units or Edge restraint with a trowel and rubber mallet, using a string line and spirit level to guide. Apply Concrete to the rear of edging, half the depth of kerb to provide strength.
4. Sub-base – Rake 50mm layers of MOT Type 1 inside the restraints, level and compact using a Vibrating Plate, passing over 7 times leaving a 100mm base.
5. Screeding – Add a layer of slightly damp Sharp Sand to a 50mm depth, compacting thoroughly before adding a further 20mm of Sharp Sand, levelling to the desired fall.
6. Paving Installation – Begin at the bottom of the slope, starting at a straight edge, ensuring the blocks are 10mm above the desired finish level. Continue with the pattern, laying all full blocks before returning to fill any gaps that required cutting blocks.
7. Finishing Touches – Sweep drive to remove debris before applying soft Sand across the entire surface to fill any gaps between the blocks. Finally, run the Vibrating Plate over the drive, using a neoprene faced or rubber sole to reduce scuffing.
