About grey block paving

Types of grey block pavings

Grey block paving comes in different types, all with unique features, aesthetics, and practical applications. Strongly used for roads, town centers, and shopping streets, the first type is the unreinforced concrete block. The second is the clay paver, uniform in size, manufactured through a natural process. Another type of grey block paving is the tumbled paved stones. They are designed to give the appearance of authentic aged paving and are often used in estate drives and traditional town centers.

The modern method of grey block paving manufacture involves carefully controlled mixing, molding, drying, and firing processes, which result in a uniform product.

A special kind of grey block paving called permeable block paving allows water to pass through the surface into the sub-base, where it can be stored and then discharged into the drainage system. Grey permeable block paving allows water to drain from the surface and can also help reduce water runoff in rainy weather.

Another variant of the grey block paving system, hydraulic interlock paving blocks, usually made of concrete, have unique shape designs that allow them to interlock when laid. This interlocking feature provides a stable, flexible surface that is often used in heavy-duty applications such as industrial parking areas, container yards, and heavy traffic roads.

Specification & Maintenance

Main specifications for grey block paving include block size, thickness, laying patterns, joint width, permeability, compatibility, and load-bearing capacity.

  • Block Size

    The typical dimensions for grey concrete block pavers are length x width x depth= 200mm x 100mm x 60mm. Other dimensions are 300m, 200mm, 150mm, 120mm, and 100mm.

  • Thickness

    The thickness of grey block paving usually varies from 60 mm to 80mm depending on the specific use purpose. 60 mm thick blocks are suitable for pedestrian areas and light traffic zones, while 80 mm thick ones are suitable for heavy traffic zones and vehicular areas.

  • Laying Patterns

    Grey block paving can be laid in a variety of patterns according to people's preferences. Common patterns include herringbone, basketweave, square, stretcher bond, and random pattern. Herringbone pattern blocks are easy to install and suitable for use areas with moderate traffic. Herringbone pattern blocks are suitable for use areas with pedestrian to moderate traffic.

  • Joint Width

    Grey block paving joint width usually differs. 2-5mm is standard, while 10mm is wide. 2-5mm is common for sand-filled and rigid joints, while 10mm works for open-graded joints.

  • Permeability

    Permeability characteristics of grey block paving products are very important. The permeability of the blocks allows surface water to drain quickly through the joints into the subgrade, preventing surface flooding.

  • Compatibility

    Grey block paving is often used with other materials, such as kerbs, circles, and steps. Grey block paving is often installed with a haunched, dry, and mortar joint, which improves structural stability and makes the joints less vulnerable to weathering and erosion.

  • Load-Bearing Capacity

    The load-bearing capacity of the grey block-paved surface is very important if it is used in heavy traffic areas like high-grade roads, airports, ports, and parking lots. High-load capacity grey blocks should be chosen to prevent cracking and structural failure.

Usually, grey block pavement only needs routine maintenance. The recommended routine maintenance procedures and schedules for grey block paving are as follows:

  • Weekly Inspection

    Users should inspect the entire grey block pavement weekly to confirm there is no damage, displacement, or cracking. They should pay extra attention to the joints and edges of the blocks. Besides, users should check if there are any weeds or debris growing in the joints.

  • Monthly Cleaning

    Grey block paving should be cleaned monthly. Users can remove debris and dust using a broom or blower. For stubborn stains, they can use a pressure washer to clean them up. Before pressure washing, they need to make sure the pressure won't damage the blocks.

  • Quarterly Weed Control

    If weeds grow in the joints of grey block paving, they can damage the integrity of the blocks. Therefore, users should implement quarterly weed control and use herbicides carefully to prevent weed growth. They can also use joint sand to fill the gaps after weeds have been removed to improve stability.

Usage scenarios of grey block paving

Grey block pavings are beneficial in various usage scenarios for homeowners and business owners. The most common usage scenario for grey block pavings is for driveways.

Homeowners can install grey block pavings to improve their property's curb appeal. Also, the paving creates a functional and attractive path for vehicles. In high-traffic areas, grey block pavings can be used to reduce the impact of heavy usage on the existing surface. Businesses can install grey block pavings on paths, driveways, and streets within the premises. The pavings create durable and robust surfaces that can withstand frequent usage.

Grey block pavings are typically used in public spaces. They are used to create durable and aesthetic surfaces in city streets, urban plazas, public squares, parks, and retail areas. Additionally, grey block pavings can improve accessibility in healthcare facilities, educational institutions, and other public buildings. The grey block pavings create functional paths for easy movement.

Landscapers commonly use grey block pavings in outdoor spaces. The material adds an aesthetic quality to patios, garden pathways, and terraces. Besides, grey block pavings are often used for architectural enhancements. The material creates attractive focal points like entrance features, border detailing, and staircases. Thanks to its design versatility, block paving is an excellent material for combining construction and landscaping.

How to choose grey block pavings

Grey block pavement shopping can get overwhelming due to the options available. Shopping for block pavements for resale requires thoroughness. When choosing grey block pavings, the following factors should influence the buying decision:

  • Colour and design options

    Block grey pavements come in various colour and design options. Buyers should consider options that will complement landscaping. Additionally, choose designs that will appeal to potential customers. Consider different hues of grey and options that incorporate other colours.

  • Quality and durability

    This is an important factor to consider because the pavement's lifespan relies on its quality. Choose block pavements manufactured with robust materials like concrete, natural stone, or clay. These materials will guarantee strength and longevity. Also, opt for pavements resistant to wear, moisture absorption, and UV radiation.

  • Surface finishes and textures

    Block grey pavements come with various surface finishes and textures. Consider the options that impact aesthetics and functionality. Customers often prefer pavement with skid resistance, dust control, easy cleaning, and glare resistance.

  • Installation and maintenance requirements

    Customers will likely prefer block pavements that aren’t complicated to install. Choose pavements that come with installation guidelines and straightforward maintenance requirements. Also, opt for block pavements compatible with standard sealing and cleaning products.

  • Pricing and budget considerations

    This is an important factor whether buying for personal use or resale. Buyers should consider pricing and determine if it aligns with budgets and potential profit margins. While quality should not be compromised, take advantage of pricing differences between suppliers and select those with competitive rates.

  • Supplier reliability and reputation

    This factor is crucial when buying in bulk. Find more information about the supplier and check buyer reviews to determine their reliability. Work with suppliers that offer excellent customer support, prompt delivery, and reasonable return policies.

Grey block paving Q&A

Q1. What is the difference between block paving and slabs?

A1. Block paving is typically smaller, and the geometry is generally rectangular. Stone paving slabs are usually larger, with irregular shapes and a more natural look.

Q2. Is block paving stronger than concrete?

A2. In general, block paving is often considered stronger than concrete because it can handle more weight. Just like a grey brick pavement, when a single block is damaged, it can be replaced without affecting the rest of the surface.

Q3. What is the life of block paving?

A3. High-quality block paving can last for 20 years or even longer with proper maintenance and installation.

Q4. Does block paving sink?

A4. Block paving sinks due to insufficient sub-base, poor-quality sand, or unbalanced load on the surface. However, in most cases, it can be repaired with proper lifting and re-laying techniques.

Q5. Which is better, block paving or tarmac?

A5. Durability and aesthetics are usually considered better than tarmac. However, block paving is more expensive than tarmac, which makes the latter a better option for some people.
