Floor Screeding Holyhead Wales (LL65): When you're upgrading your Holyhead property that has damaged or uneven floors, or perhaps converting a basement or cellar to useful living space, a competent floor screeding company can provide you with a firm starting point. A screed is used to generate a smooth floor over a rough concrete sub-base and provide a solid base for you final flooring material. A floor screed is a fundamental element of most building and restoration projects in Holyhead.
FLOOR SCREEDING CONTRACTORS HOLYHEAD
It does not matter how big or small the area you need to be levelled, an established floor screeding firm in Holyhead will have the appropriate equipment, expertise and knowledge to give you a superb standard of service. After a meticulous assessment of your project, they will be in a position to inform you about which method of laying is best suited to your circumstances, and what is the best screed.
Your screeding contractor will also inform you if a structural engineer is required for your undertaking, in order to evaluate flex strength, load requirements and point loadings that your screed floor might need to conform with British Standards and building regulations.
Qualified and skilled tradespeople are necessary for a successful outcome and will extend the life of your floor through the use of the right kind of screed for your room's intended purpose. Picking the correct screeding materials and the method of installation is critical if you want to finish up with a quality and durable finish for your floor surface.
Ensure you get more than one estimate for your Holyhead based floor screeding project and also ask what standard of finish each quote is for. The SR (Surface Regularity) finish is the number to keep your eye on when reviewing a quotation from your Holyhead screeding contractor. SR1 is the best quality, and whilst SR2 and SR3 might be less expensive at first glance, they do not guarantee a totally even or flat floor surface. An SR2 or SR3 level may mean there are flat spots or ridges that could cause issues when installing your final floor surface.
The regulations and guidelines set out in in the British Standards BS8204 have to be followed by any Holyhead floor screeding contractor and they should also hold accreditation with the manufacturers of specialist screeding materials (Gypsol, Flowcrete, Cemfloor etc.) to prove their safe working practices and competence. A contractor holding accreditations demonstrates that they have been assessed and trained in using these screeding products and can offer a high quality service in all aspects of their installation.
Holyhead commercial screeders may be involved in the screeding of floors in boutiques, factories, shops, schools, warehouses and hospitals.
TYPES OF SCREED
Standard Screeds - A blend of sand and cement which is okay for normal residential use. The standard screed is a mix of five parts sand to one of cement. The standard flooring screed dries at a rate of 1mm thickness each day.
Fibre Reinforced Screed - The professional's choice for domestic use over the top of under floor heating. The greater flex and strength offered by the special fibres in this screed help protect the flooring from thermal cracking and shrinkage. At about one millimetre per day, it has a similar curing rate to standard screed.
Polymer Screeds - A high strength solution where a reduced screed thickness is needed. Polymer screeds are available from a number of screed manufacturers and owing to their different chemical compositions have distinct drying times for each product.
Fast Drying and Advanced Drying Screeds - As the name suggest, these screeds dry quickly and allow you to use the floor area much sooner. These are typically a fibre reinforced type of screed that dries out at a rate of between 3-7mm/day per day and are employed in time critical projects.
Self-Levelling or Liquid Screeds - A cement and latex material which can produce the highest standard SR1 finish. Mostly used to improve a poor substrate level or damaged floor so as to lay a brand new flooring surface, such as tiles over it. The liquid screed can be laid to a depth of only one millimetre, but will still provide a high strength base to take a wide variety of flooring materials.
Industrial and Heavy Duty Screed - Made for maximum durability and strength on floors where traffic is expected to be high or specific loading of the floor base is required.
SCREEDING PREPARATION AND INSTALLATION
Preparation is vital for a high quality screed surface that will be hard wearing and durable. Any paint, grease, debris and oil on the existing floor level can adversely affect the bonding of the screed, and should be eradicated.
If any products were used in this process it's important to ensure that no residues of soaps or other cleaning products are left on the floor surface and it is allowed to dry out naturally. At this stage cracks should be repaired as these can travel up through your laid screed and be reflected in the finished surface. During a site survey your Holyhead screeding company will notice what preparations are needed before any actual screeding work commences.
Before any screeding can be laid a damp proof membrane (DPM) must be put down to protect the screed and final flooring from moisture. The damp proof membrane is made from thick polythene sheeting and various layers could be used to act as a moisture barrier for the screed.
If the area where you live is at risk from radon then one additional barrier is needed to prevent the gas from entering via the ground. If radon gas occurs in large amounts then a complete ventilation and extraction system may be installed beneath the screed which will remove any gases that might seep in from the ground.
The final stage of the surface preparation process is the spraying or painting of a sealer or primer. These primers and sealers will make certain the screed bonds successfully to the base and help create a quality finished floor. Devices such as airless sprays are used to apply a primer or sealant, which should be done by certified screeding contractors in Holyhead sticking to the manufacturer's guidelines.
Now is the time that under floor heating can be installed and laid out in the correct manner. Insulation panels can be arranged and the heating pipes and cables will be securely fastened so that there is no movement while the screed is applied. When properly installed an under floor heating system is an effective way to warm up a room and decent quality screeding retains its heat, creating an even level of warmth across the floor.
If you are not putting in under floor heating the screed can now be prepared in situ and poured. Your screeding specialist will have given you advice and guidance on which screed type is suitable for your requirements, according to your proposed use of the room. Remember that even quick drying screeds have a minimum of twenty four hours before you're able to walk on any screeded surface and at least 72 hours before any floor coverings can be fitted. Manufacturer's drying instructions for standard and heavy duty screeds should be observed in order to achieve a quality finish and end up with an even and stable surface.
The SR level of your screed can be ascertained once it's hardened enough to be walked upon. Using a two metre straight-edge the surface is examined for any dips, ridges and deviations in the screed surface.
- SR1 - Disparities of 3 millimetres or less as measured across the entire area shows your screed floor to be of the highest quality and is specified as SR1.
- SR2 - SR2 is for normal standard commercial and industrial floors and can deviate from the straight-edge by up to 5mm.
- SR3 - If the deviation is 10mm or less the screeding quality is classed as SR3 and is the standard required for utility and garage areas.
If your screed has been laid with particular loading in mind then a qualified structural engineer will be required to perform tests. The assessment will make sure that your new screed is viable for the load point requirements set down in the site survey. The screeding should be subjected to a drop hammer test to determine strength and flexibility in distinct areas. The precise measurement and testing tools mean this can only be carried out by a trained structural engineer heeding the guidelines of the British Standards BS8204.

Latex Floor Screeds
When a degree of flexibility is necessary in the surface of a floor you might find that the use of a latex self-levelling screed will be advantageous. Normally coming in two parts, latex floor screeds comprise a cement-based compound, and a liquid latex additive. Whereby water is normally used in a screed mix, this is replaced with the latex liquid, meaning that it's more flexible than other types of screed, and quicker drying.
This latex screed compound is used to level a subfloor before the final decorative surface is laid. This is appropriate for use on sub-floors of sand/cement, asphalt, concrete, wood and stone tiles, to give a smooth, durable surface which is ideal for the application of adhesives. If there happens to be a bit of movement in the sub-floor this latex screed will give you a flexible, crack-free finish on which you can lay your chosen floor coverings.
When a screed is being laid over a layer of either acoustic or thermal insulation (i.e. a "floating" screed), latex floor screeds are not appropriate, because in this case (normally when screeding on top of underfloor heating), you'll probably require a thickness of 50-75mm.
Screed Floor Removal
The process of removing screed from a surface involves extracting and disposing of the pre-existing layer. Often, when upgrading or renovating a a floor in Holyhead, it is a necessary undertaking. To effectively break down and remove the screed layer, specialised equipment and techniques are indispensable in the removal process. It permits the surface to undergo preparation for new flooring or other alterations. Skilled professional contractors in screed floor removal guarantee the efficient and safe elimination of the old screed, enabling a renewed beginning for the floor, be it for repairs, changes in design or upgrades.
