At Unique Choice our Driveways and Patios are some of the finest to be found in this area. We have unrivalled expertise. All are laid on the correct foundations for your particular site, application and for the drive you choose. Please see below the various types of drives we offer, just click to see.
With our in house designers we can design the driveway or patio that you had in mind.
As with any project PLANNING, PREPERATION, MATERIALS and the quality of WORKMANSHIP is paramount. Cutting corners or quantities used can result in devastating consequences for the consumer further down the line.
Points to consider when assessing a project;
1. What is to be achieved by the work, i.e. to improve aesthetics or functionality?
2. If the driveway or patio has become uneven or broken down WHAT HAS CAUSED IT?
3. If the area to be looked at has not got any surface i.e., lawn to be paved to extend a drive or new patio area where there is none then we must consider:
- The ground to be worked on is it boggy, muddy or bone dry (how deep to excavate)
- Where would surface water go to (drainage requirements etc.)
- Does the project require planning approval?
- The overall finished height of the project and how would this affect the damp course integrity (regulations in UK state all finishing courses should NOT be higher than 2 x 73mm brick courses below the damp course line.
- Does the required or desired product cover all aspects of the above and will it provide a project when completed that will outlive our GUARANTEE OF 10 YEARS COVERING:
- Sinking (natural land movement or act of god i.e. Tremors subsidence)
- Movement – if excessive movement is apparent and not caused by the above or due to excessive weight.
- Water retention (puddling or holding surface water and not draining effectively or naturally)
Drainage is a major issue and this is paramount and MUST be looked at from a common sense approach to provide the correct way for the water to disburse, this can be done in two ways:
1. Natural run off (getting levels and falls correct)
2. Soakaway (this is an area where the water has no natural permeable disbursement so an aggregate is installed to 1m3 (cubic meter) prior to sub base to allow water down to drain to the section naturally.
3. ACO or gully channels to disburse water to a manipulated point (gully etc.) by creating falls and levels to run water to a collection or collections points, which also help to protect damp course integrity and stop puddling.
4. French Drains – A channel of aggregate that runs around a building perimeter no wider usually than 100mm. This allows a natural soak away to provide protection against damp and also protects and stops footings and foundations from drying and cracking.
All groundwork that is completed without the correct depth of excavation and amount of material installation will either, SINK, MOVE or SUBSIDE as the substrate (base) is the most important installation of all, and without the correct type of stone used with the correct quantity this will eventually fail.
When installing a substrate there are many types of stone to use,
– the types are as follows:
CRUSH AND RUN – a term used for crushed rubble that is reclaimed, usually concrete and bricks. This is NOT adequate as there is NO consistency in type or size so when this is compressed it leaves pockets of weakness in the layers.
BALLAST – this is ONLY appropriate to be used where soakaways are to be installed for permeation and it is used with permeable block paving as a second course after hard-core has been installed.
MOT TYPE 1 LIMESTONE ROADSTONE – this is the CORRECT material to be used as it is recommended by ALL government agencies, for strength, loadbearing, compression and permeation.
Large aggregate with lime grit that once compressed is VERY solid and if depths are correct will prevent movement, however most companies will not use this as it is more expensive or they will put down less than is needed due to cost saving.
SECOND OR BINDER COURSE
Different surface courses and conditions require different solutions to maximize longevity of the surface providing support and flexibility to stop excess movement.
A typical substrate depth of hard-core is 150mm (6 inches), the second course will typically be 80 – 100mm (3 – 4 inches) of sharp sand, lime grit with block paving, compressed and excess is screeded to the correct levels to create a perfect laying blank canvas.
THE SECOND COURSE IS AS IMPORTANT AS THE BASE
