Floor Screeding Welwyn Garden City Hertfordshire (AL7): When you are upgrading your Welwyn Garden City property with damaged or uneven floors, or maybe converting a basement or cellar to useful living area, an established floor screeding company can provide you with a firm starting point. Floor screeding provides a smooth, level finish to a rough sub-base, and allows you to lay a suitable flooring material, (carpets, boards, tiles etc) on top of it. If you would like your floors to last a long time then a floor screed is one of the most important factors in any renovation or building task.
FLOOR SCREEDING COMPANIES WELWYN GARDEN CITY
A professional floor screeding specialist in Welwyn Garden City will have all the experience and knowledge to help you achieve a perfect floor in whatever size or shape of room you are renovating. They'll assess the project and verify the appropriate kind of screed you need and how best to apply it.
They'll additionally assess if a structural engineer is necessary to make certain any point loadings, flex strength and load bearing are met as set out in the building regulations.
The training and skills that a certified screeding specialist brings to your project will guarantee a successful end result and help in prolonging the lifetime of your flooring. The correct blend of screed and the methods used in laying it are also crucial to ensure the final intergrity of your floor surface.
There are a number of screeding contractors in the Welwyn Garden City area so see if you can get multiple price quotes for your floor screeding project before picking a contractor and know to what standard of finish is it for. The SR (Surface Regularity) finish is the figure to keep your eye on when receiving an estimate from your Welwyn Garden City screeding contractor. SR2 and SR3 may be less costly options, but the floor screeding finish may have errors and deviations, whilst SR1 guarantees a pretty much perfect quality of finish. Any error in the screeding (as might arise with SR2 or SR3) can cause issues with laying flooring due to indentations, flat spots, ridges in the floor surface.
British Standards BS8204 lays out the guidelines and regulations that all Welwyn Garden City screeding contractors must follow, and if applying specialist screeding solutions, (Flowcrete, Cemfloor, Gypsol etc), they should be approved by the manufacturers as being skilled and trained in their use. A contractor holding such accreditations demonstrates that they have been assessed and trained in the use of these screeding products and can offer a high standard of service in all areas of their installation.
For larger screeding projects in warehouses, schools, shops, factories, boutiques and hospitals, dedicated commercial screeders in Welwyn Garden City will be required.
TYPES OF SCREED
Standard Screeds - This is perfect for regular domestic use and comprises a mixture of sand and cement. 5 parts sand to 1 part cement is the usual mix for standard flooring screeds. The standard screed dries at a rate of one millimetre thickness per day.
Industrial and Heavy Duty Screed - Where levels of traffic are expected to be high or heavy loading of the floor is necessary, heavy duty screeds provide maximum strength and durability.
Polymer Screeds - A high strength flooring solution where a reduced thickness is needed. The drying times vary in accordance with proprietary product guidelines.
Fast Drying and Advanced Drying Screeds - If you need to move forward urgently with the work on account of time restraints, this screed dries more speedily than standard flooring screeds. The vast majority of the fast or advanced drying screeds are fibre reinforced and are suitable for a wide array of projects where the swifter drying rate of 3-7mm is a big advantage.
Self-Levelling or Liquid Screeds - Used to provide the highest quality of finish, especially where SR1 levels are needed, by a cement and latex mixture. Largely used to finalise a damaged floor or poor substrate level so as to lay a new flooring surface, such as tiles on the top of it. They can be as little as 1mm in depth, and because of the latex polymers, will still provide a high strength finish.
Fibre Reinforced Screed - The first choice where under floor heating is being installed in domestic homes in Welwyn Garden City. The special fibres in this screed improve it's strength and durability while also safeguarding against thermal shrinkage and cracking. At around one millimetre per day, it has an identical curing rate to standard floor screed.
SCREEDING PREPARATION AND INSTALLATION
To enable the screeding to be of a good quality finish which is durable and hard wearing, time must be devoted to fully preparing the area prior to any screed being poured. Any paint, oil, debris and grease on the existing floor surface can affect the adhesion of the screed, and should be eliminated.
Any cleansing chemicals used during this stage shouldn't leave any residues, and the floor base must be allowed to dry out naturally. At this stage any cracks need to be mended because these can travel up through a newly laid screed and be reflected in the completed surface. A skilled Welwyn Garden City screeding contractor will take note of these issues during the site survey and make sure that all preparations are complete before pressing on with the next stages of the screeding process.
Before any screeding can be laid a damp proof membrane (DPM) must be put down to shield the final flooring and screed from moisture damage. The DPM is made out of thick polythene sheeting and different layers may be used to serve as a moisture barrier for the screeding.
If the area where you live is at risk from radon then another barrier is required to stop the gas from entering from the ground. This can be just a simple airtight membrane, or in more serious instances an extraction and ventilation system will be installed underneath the screeding to draw out any inflow of radon gas from ground level.
As soon as the floor base has been prepared and any DPMs installed, a sealer or primer is then put on. A primer helps with the screed bonding process to the base surface and different types exist depending on which type of screed is being applied. On account of their specialist nature, only professional screeding contractors in Welwyn Garden City should be entrusted with using them safely and correctly and using bespoke equipment for the task.
Underfloor heating can now be installed and checked before the screed is poured. The heating pipes and wires are securely attached to insulation panels to stop any movement and make certain that they are positioned correctly. When expertly installed an under floor heating system is an effective way to warm a room and decent quality screed will retain its heat, creating an even heat right across the floor.
If you are not fitting under floor heating the screed can now be prepared in situ and poured. Your use of the room will help your screeding company on which form of screed is best for your needs. For advanced and quick drying screeds there will be at least a 24 hour delay before it is able to be walked over, and a further 72 hours minimum before you can lay any flooring materials. If you're looking to end up with a well finished and long-lasting floor surface you should follow the manufacturer's guidelines with regard to standard and heavy duty screeds where this waiting period will be longer.
The SR standard of your screeding can be checked once it's set sufficiently to be stepped onto. Through the use of a 2 metre straight-edge the floor surface is examined for any ridges, deviations and dips in the screed surface.
- SR1 - SR1 is the best level and permits only three millimetres of deviation from the straight-edge.
- SR2 - SR2 is the classification for standard commercial and industrial floors and can deviate from the straight-edge by up to five millimetres.
- SR3 - SR3 is utility standard where a perfect finish isn't necessary. This specification can have a maximum permissible deviation of 10mm.
It may also be necessary for a qualified structural engineer to conduct a soundness test. Using specialist equipment the structural engineer will establish the screed strength and its suitability for use in a load bearing setting. An assessment called the "drop hammer test" is carried out at several areas on the screed layer and the results recorded. Any screeding that has point load requirements must be sanctioned by a certified structural engineer following the BS8204 guidelines.
