Premium Block Paving

Block paving is one of the most flexible paving options in terms of where it can be used. Whether it's for a driveway, a pathway or even a patio, there's probably a block paving product which would suit your requirements. Whether you're looking for a time-worn, cobble effect or sleek and contemporary chic, block paving can be used to completely transform both the front and back of your property.

Simply Paving supply Concrete Block Paving (CBP), we do not supply clay block paving.

As with any type of paving, your first consideration is the exact area of use and the type of use for that area. If you are looking to pave a standard domestic driveway (for your average family car), pathway or patio, then a 50mm product is generally sufficient. However, if you are looking to pave an area where particularly heavy vehicles are likely to overrun or where there is very frequent traffic passing over, a more heavy duty 60mm or 80mm product is advisable. These products are suited to more commercial applications and can be found in our Heavy Duty Block Paving section.

Budget will also have a bearing on the type of block you choose, with products ranging from the more economical 200x100mm rectangular block paving that is familiar to most, to products that may have multiple sizes available or more premium finishes.

Many of the more established ranges are manufactured with the same mix and colouring throughout the block but there is an increasing trend for block paving products to be manufactured with what is known as a 'face mix'. This is where the high quality colour and finish mix is only used on the upper most part of the block i.e. the part that is visible when laid. The rest of the block (the back mix) is manufactured from a more cost effective mix - quite often recycled aggregate. This results in a high quality finish, without the expense of a block manufactured entirely from premium materials. Both parts of the block cure as one and therefore, there is no risk of weakness or delamination of the layers.

If you are using the block paving at the front of your home, there are also drainage regulations that you will have to consider and this may well be an important factor in the type of block you choose. Information on the drainage regulations and permeable solutions for driveways can be found in our Advice Centre. If a permeable solution is required for your property, these can be found on our website and are generally identified as "Infilta" permeable block paving products. These products are laid using a different construction method to standard block paving.

The most common and the recommended method for laying domestic block paving is what is known as a flexible construction. This means that the blocks are laid on an unbound (cement free) laying coarse and jointed with a fine sand (kiln dried sand). Concrete block paving is not laid on a mortar or bound laying coarse. For further information on laying block paving, please refer to our Advice Centre.

As with any other type of paving, regular maintenance is important to keep the area clean and free from moss and algae. We recommend thoroughly washing paved areas with warm soapy water and brushing off with a stiff broom three or four times a year. High pressure washers are not recommended for regular use, however, they can be used once a year with care being taken not to wash the sand from between the blocks. Even with careful pressure washing, it may still be necessary to reapply kiln dried sand to the area once dry.

With regard to weeds, it is not normally the case that they are growing through the sub base and laying course, they usually seed in the sand joints between the blocks. Therefore, it is not generally possible to prevent weed growth with a barrier or membrane, however, it may be worth treating the area on an annual basis with a general purpose weed killer. For information on weed killers, please contact the manufacturer.

Efflorescence can be a characteristic of all quality manufactured products with a high cement content. It appears on concrete paving as white patches or a lightening of the surface colour, but seems to disappear when wet. It is formed by a normal chemical reaction between cement and water which causes calcium hydroxide (lime) to migrate through damp concrete to the paving surface and then react with carbon dioxide in the atmosphere resulting in a deposit of calcium carbonate crystals. Efflorescence is very unpredictable in its occurrence but is more prevalent in winter when concrete becomes wet and dries more slowly. Although there are cleaners available, efflorescence is a natural phenomenon and will generally disappear with the natural weathering process and the passage of time.

As block paving products are likely to have vehicular overrun in most applications, there is a risk of oil spillage. As such, sealing the area can be worthwhile. For further information please contact Simply Paving or the Bradstone customer care team. For information on specific sealants, please contact the manufacturer.

Depending on the range and the style of product that you choose, mainly whether you choose a single size or mix of sizes, there are various different laying patterns available. A single size block allows for a greater number of actual laying patterns, whereas, a mix of sizes limits the number of patterns available but allows for the finished area to appear more random without a repeating pattern. Examples of laying patterns for single size blocks include herringbone, stretcher bond and basketweave. Mixed size blocks are generally laid in a random stretcher bond pattern.
