Installation Process

Imprinted Concrete Installation Process
Stage 1 - Consultation and Confirmation
  • One of our surveyors will visit you at your home at a time that is convienient for you.They will discuss with you, your prefered designs and colours and offer you friendly experienced advice on how to maxamise the aesthetics and practicality of your future pattern imprinted concrete installation.

  • If you are unfamiliar with the processes involved our surveyor will go through they key points of the installation which may effect you during the your imprinted concrete installation.

Stage 2 -Setting a Start Date
  • When you are satisfied with your choice of design and colours, contact us at Paul O'Flynn Pattern Imprinted Concrete and relevant paperwork will be completed. We will then agree on a date in which the installation process will begin.

  • Weather is a major factor with imprinted concrete. The installation process heavily depends on what the Irish weather throws at us. As the agreed installation date approaches, we will reconfirm the starting date. We are usually able to carry out the initial steps of the installation process in most weather conditions. However, we require dry weather on the day concrete is to be poured and hence sometimes the start date may be delayed. We will try our best not to deviate too far from the start date but unfortunately the weather is the main predictor.

Stage 3 -Job Site Preparation
  • Generally most sites have previously installed paving brick, tarmac, concrete or slabs. Removal of these will be carried out using suitable plant machinery for the job site. For tight small areas, hand excavation may be carried out if mini excavators cannot access the area. Preparation usually takes one day, but can take longer if the scale of the work is larger.

  • 804 and surface blinding is generally used to achieve the desired levels and falls for the pattern imprinted concrete installation.

  • Drainage requirments, addition of Aqua drains, recess man holes and other requirments are addressed and installed at this stage. These are all set at the correct finshed levels prior to pouring.

  • Shuttering to achieve your choosen outside perimeter shape are erected and also set at the correct finish levels.

  • At this stage we are ready to pour the concrete the next day, provided of course that there are no delays due weather conditions or any other unforseen factors. If the weather forcast is not favorable, the site is left in a tidy manner so that you can use the area until we can return to pour the concrete as soon as the weather picks up..

Stage 4 -Imprinted Concrete Installation (Pour Day)
  • On the day of imprinted concrete installation we will arrive on site about an hour before the concrete is due to arrive. Usually we will arrive on site at 7:30-8:00AM.

  • During this first hour we will prepare our equipment and lay down polythene to protect walls, windows, doors and any other areas which need protection from concrete splashes, colour surface hardner and release agent..

  • Our supplier will deliver the specially mixed concrete in a cement truck.

  • The concrete is poured and levelled to the required predetermined levels and falls, screeded, roller bugged (to bring up the fat) and troweled. Generally it takes two hours to do this on a 50m2 pour. This may vary depending on the accesibility to the job site and unloading of the concrete.

  • The concrete is then coloured with the powder colour surface hardener (your main colour of choice). One bag per 10m2 is cast out over the wet concrete.

  • The concrete is then closed and when the condition of the curing concrete is suitable, the colour powder relase agent (your secondary colour of choice) is broadcasted over the closed coloured concrete.

  • The colour powder release agent prevents the imprinting mats from sticking to the concrete during printing. It also adds a secondary antique colour to the imprint, which gives the imprinted concrete its natural stone like effects. Finially it is hydrophobic by nature, hence it can repel small quantaties of water from the surface and protect the concrete surface during the curing stages.

  • Once imprinting has been completed, the site is closed off. Pets need to be kept away just in case they wander over the imprinted concrete. The release agent is a very fine dust which you must try to avoid getting on your shoes and bringing into your home until it is power washed after a few days.

Stage 5 -Cutting Of Expansion Joints
  • During summer months expansion points (control joints) need to be cut within a 24 hour period after the concrrete has been poured.

  • During winter months, this 24 hour period is not as critical as the concrete surface may not have cured enough within the 24 hours. Hence the cutting of control joints is usually delayed by two days or more.

Stage 6 -Removal of Powder Release Agent
  • Once we are satisfied that the concrete surfcae is fully hardened and cured (usually after a few days), we will remove the release agent from the surface of the concrete.

  • Firstly we remove the excess release agent powder by brushing the surface clean.

  • The surface is then treated with a release agent wash. This will break down more surface release agent and remove the majority of the remaining powder.

  • The surface is then immediately power washed to remove both the acid wash and remaining free release agent.

  • The above steps are repeated if we feel that more removal is required.

Stage 8 -Sealing
  • The pattern imprinted concrete surface must be throughly dry before sealing can be considered. The Sealing process is also weather dependent. On days with a strong risk of rain, we may decide to postpone sealing until a more suitable day.

  • During summer months sealing maybe carried out the same day as the removal of the release agent. This alll depends on the drying conditions.

  • After sealing, the control joints (expansion joints) are then filled with a bead of silicone filler. This prevents the build up weed harbouring dirt.

Stage 9 -Completion of Installation Process
  • After sealing is completed, Aqua drains, gulleys, manhole covers will be checked to ensure that they lift freely and easily..

  • Any remaining items from the intallation process will be removed and the site will be cleaned .
