To DIY or not to DIY?


Although it may look easy to perform block paving, the truth is that this is a job that is best left to experienced professionals. We have several available that will be able to provide you with reasonable quotes for having this work done.

When doing block paving in a DIY capacity, you will not have any form of warranty. In the event of anything going wrong during or after installation, you will most likely have to hire the services of a professional to rectify what has been done – which will ultimately cost more than if you had simply hired them initially.

Another consideration to factor in is that block paving takes a lot of time to complete properly. Many homeowners simply don’t have the time to do this. In cases where your block paving is not fully level, water will dam up and blocks can end up loosening over time.

Steps Involved in Performing Block Paving


Here is a basic overview of the steps required to perform block paving to perfection:

1. Marking out the work area

Your tradesperson will determine which parts of your yard are going to be paved, and these will be marked by using string lines or spray markers. In cases of larger than average projects, it may be beneficial to have a construction plan drafted.

2. Excavating

The whole area that has been marked off will need to be excavated. Most tradespeople will hire a small excavator or digger so that work can be completed quicker. Existing cement can be broken down with a jackhammer, and skips must be hired to remove excess sand. Digging should be completed to between 20 and 25 cm below the planned paving level.

3. Preparing the sub-base

A sub-base will have to be spread, levelled and compacted and scalping stone is normally used for this. A minimum of 10 cm is recommended for this so that holes can be levelled and the proposed paving profile can be matched. It’s strongly recommended that a geo-membrane be used on top afterwards.

4. Placing edging stones

A restraining edge will be required to keep the paving block in place. An existing kerb can be used or new edging stones can be laid. It’s recommended that your tradesperson secured these within approximately 7.5 cm of cement.

5. Laying Coarse Sand

Coarse sand will have to be spread and levelled out, and then thoroughly compacted with a vibration plate. Using screed can create a solid base for the block pavers because it has to be smooth and match the planned level of paving. It’s recommended that this be between 2.5 cm and 4 cm thick.

6. Laying down the blocks

Each block will now be pressed closely together as they start bedding into the sand.

7. Cutting in and aligning

The alignment of your blocks will then be checked with a string line. It’s recommended that bricks be laid with overlapping joints, and cuts can be made to fit the final blocks with a disk cutter.

8. Final touches

Gully covers and recess trays will now be fitted if needed.

9. Jointing

Kiln dried jointing sand will be spread over all of the paving, and this should be brushed down into all of the joints. The whole area should then be evenly vibrated for a few minutes without removing excess sand.

10. Repeating

More jointing sand should now be spread and the blocks vibrated again for a few more minutes. This process must be repeated until such time as all of the joints have been filled with sand.

Is Planning Permission Required?


Official UK regulations state that no planning permission is required if you want to lay permeable concrete block paving along a driveway or in a yard.

In cases where impermeable blocks are being installed, allowance must be made for water to seep into a suitable drainage area like a border or lawn. If no appropriate drainage areas are available, planning permission will need to be obtained of mire than 5 square metres of block paving is going to be installed.

Available Paving Options


The two most common available options for paving blocks are cement and clay. Below is some basic information pertaining to each type of block:

Clay

  1. More durable and hardwearing
  2. Longer lifespan
  3. Their natural colour doesn’t fade
  4. Various pattern option can be purchased
  5. Sizing may not always be exact with each block
  6. They are prone to moss growth
  7. Available block depths are limited
  8. Challenging to cut and difficult to work with
  9. Costlier per block than cement

Cement

  1. Lower priced than clay
  2. Sizing of each block is more accurate
  3. Different shapes, block depths and textures are available
  4. Can last approximately 20 years
  5. Colour can fade over time
  6. Aggregate can become exposed as they age

How Long will Block Paving Take to Complete?

An experienced team of professional block pavers will be able to have a 55 square metre driveway completed within five working days.

On day one, a small team of workers will complete the initial groundwork, and this can be quite a noisy process. The days thereafter will often only require a few labourers to prepare the surface and lay the block paving. After everything has been laid, the compacting process will start. This can also be quite noisy.
