The first sight your guests are presented with is the front of your house. This includes the driveway. We all understand the importance of good first impressions; therefore, if you have decided to take up the task of re-constructing your driveway, we are presenting you with 5 easy steps to create the perfect block paved driveways.
Step 1: Plan and Prepare
It is always best to start with a detailed plan in mind before you go and begin excavating your driveway. There are a number of things you will need to consider. These include:
- A Design: A detailed layout based on your customized requirement.
- Blocks: What types of blocks do you intend to use?
- The Colour: Are you aiming for a pattern, or simply want something to match your house’s colour?
- Once decided, ask yourself if you want to replace or extend your existing driveway.
Step 2: Excavate
Using a mini excavator, the existing driveway must be dug up. Start by marking the area that needs to be dug up. Once sure, start excavating to the desired depth, which should ideally be 150mm below the proposed finishing level. Next, the excavated area must be scrutinized for its level of inclination. If the area appears to be flat, it could very well retain water instead of dispersing it. When constructing an inclined plane using bricks, it should be at 1:80 fall along the length and 1:40 fall across the width of the driveway.
Step 3: Edge Restraints
For the perfect cement mixture, mix 1 part cement with 6 parts of ballast for the 100mm thick edge restraint. Using a spirit level and a string line, make sure that the edge restraint unit will ideally sit at the desired finishing level. Next, using a trowel, concrete and a rubber mallet, mortar the edge restraint unit to form a haunch which is at least ½ of the block height.
Step 4: The Sub-base
When laying the sub-base for the block paved driveways, use MOT Type 1 Roadstone or Type 1 crushed concrete to fill the edge restraints and scrape in layers to a desired level of 50mm. Using a vibrating plate, ensure that it is well levelled. The vibrating plate must be passed over at least 7 times to ensure detailed compaction of the area. After compaction, the Roadstone must be at least 150mm thick.
Next, using the vibrating plate, layer the surface with slightly sharp and damp sand to a depth of 40mm, ensure maximum compaction, and ensure that the area is properly levelled as per the design. For this purpose, string lines, straight edges and screeding rails should be used.
Step 5: Installation and Finishing Touches
It is advised to always start from a straight edge or a right angle, ensuring that they sit at least 5mm above the desired finishing level. If you are using different coloured blocks, pick them one at a time from the packs to minimize colour patching.
Next, you will be required to cut off some blocks to fill the end space in the area. This can easily be done using a diamond disc cutter or a block splitter. Before you do this, go through the manual for cutting blocks. Look for proper instructions, equipments and the accurate level of exposure to make sure it is done properly.
As for the finishing touches, using a yard broom and kiln sand, brush the newly block paved driveway to ensure that the joints in between the blocks are thoroughly compacted and are at an envisioned finished level. Layer another kiln to re-compact any joints that may be in need of a filling.
