Block Paved Surfaces
What? Professionally laid block paving driveways, guaranteed for 10 years as standard. Otherwise known as brick paving, it is a flexible and decorative driveway solution which allows individual blocks to be removed and replaced when necessary. The most common materials in use for the block paving brick are concrete and clay.
Why? O’Hanlon is the premier contractor in the south east.
When? When it is suitable for you.
Where? Anywhere in southeast England.
How? With quality materials and skilled craftsmen.
Technical: Proven 30 tonne stress loads; and working to a 3mm tolerance.
Our design to completion approach ensures you have one point of contact for your project, which we will manage from your initial enquiry through to final satisfaction.
Once the design has been decided by the customer, constructing an O’Hanlon driveway is a 12-stage process:
Break-out and remove surface (including any existing driveway and/or other surface) and excavate the ground to a depth of 11” (28cm), in preparation for the various layers.
A blinding layer of sharp sand is evenly spread across the excavated area and compacted. This layer helps create a level surface to begin laying the subsequent layers upon.
A high quality geo-textile fabric terram membrane is laid on top of the layer of sand to prevent any plant growth, which could cause potential damage to the sub-structure over a period of time.
Stages 4 & 5:
Both stages are a layer of type 1, compacted down to an inch (2.5cm) in depth for each. These are the first layers that will provide real strength for the driveway as they act as the foundation of the whole driveway.
A concrete bed laid around the perimeter in preparation for the individual laying of the edging blocks.
Laying of the edging blocks and/or kerbing to a 5mm tolerance.
Stage 8 – 10:
All three stages are a layer of type 1, compacted down to an inch (2.5cm) in depth for each. This provides further structural integrity for the driveway, culminating in a proven 30 tonne stress-load.
A layer of compacted sharp sand, screeded off to a 12mm ride height, set by the determinable height of the edging block.
The final stage is the laying, cutting and compaction into place of the paving blocks to a 3mm tolerance.
