A block paved driveway is usually more expensive than a concrete one when you add everything up. The blocks themselves cost more to make and there is a lot more labour involved in laying them one by one and getting the pattern right. It takes more time and a bit more patience to do properly which adds to the price.
Concrete is quicker to pour and finish so the labour costs are lower even if you are using a decent mix. If you go for extras like colour or a stamped finish the price can creep up but plain concrete still tends to come out cheaper than block paving.
That said, block paving is easier to lift and fix if something goes wrong or if you need to get to a pipe underneath so over time it can save you a few headaches. Even if you get a bit of settlement or the odd dip over time you can take up just that section of blocks, level it back out with fresh sub base and put them back like nothing happened.
Yes a concrete driveway generally handles heavy loads better than block paving especially if it is poured thick enough and done right from the start. Concrete is a single solid slab so the weight is spread evenly across the whole surface. That makes it ideal for things like vans trailers or anything heavy that is going to be parked up for long periods.
Block paving can still take plenty of weight if it is laid properly with the right sub base and edge restraints but each block works on its own and relies more on the compaction underneath. Over time if the base starts to shift or if water gets in you might see some dips or loose areas forming especially where heavy vehicles are turning or braking.
So for heavier use concrete tends to hold its shape better and needs less attention over time. Block paving can still do the job but it needs that base done properly or it will start to show wear quicker under constant load.
For uneven ground block paving is often the easier option because it can be adjusted as you go. The base gets compacted and shaped to suit the slope and the blocks are laid one at a time which gives more control over the levels. If the ground shifts later or you get a bit of settlement you can lift a few blocks reset the base and lay them back down without too much hassle.
That said it is absolutely possible to lay a concrete slab on uneven ground but it takes more prep. The ground needs to be properly levelled or built up with a solid sub base and sometimes you will need formwork or shuttering to hold the concrete in place during the pour. On bigger slopes you might also need to include a step or retaining edge to keep things neat and supported.
So block paving gives a bit more flexibility and is easier to tweak if the ground is awkward but concrete still works fine if the base is done properly.
Both block paving and concrete can hold up well over time if they are laid properly but they each have their own way of wearing in. Concrete is one solid slab so if the base is strong and it is poured to the right thickness it will last for years with very little movement. It is less likely to shift about and does not get weeds growing through the joints. But if it cracks it is harder to fix and any patch will always stand out a bit.
Block paving might move a little more over time especially if the base was not compacted right or if water gets underneath. But it is much easier to repair. You can lift individual blocks level the base again and drop them back in like nothing ever happened. If you keep the joints topped up with kiln dried sand and clean it now and then it will last just as long as concrete.
Yes you can seal both a concrete and a block paved driveway and it is a good idea if you want to keep them looking sharp and help protect them from stains moss and general wear. Sealing concrete helps stop oil water and dirt from soaking in and can also bring out the colour if you have gone for a decorative or coloured finish. It gives the surface a bit more protection and makes it easier to clean.
Block paving can be sealed too and it helps lock in the jointing sand so it does not wash out in heavy rain. It also helps stop weeds and algae from taking hold in the gaps and gives the surface a bit more resistance to marks and fading. Just make sure the blocks are clean and dry before sealing or you will trap in dirt and moisture.
Both types of sealers come in different finishes like matte satin or gloss depending on what look you are after.
