There are many types of screeding that we can provide for you and we have created a list that explains the different sorts available. We can provide you with these as a full package or as a labour only service for your domestic and commercial projects within the London and South East area. Call us today for advice and a free quotation for your project.
Sand and Cement Screed is otherwise known as traditional screed. Sand and cement are the basic components and are combined together with water using a pump or mixer. It is ideal for every situation and can be used over insulation and with underfloor heating. It can be combined with other products known as admixtures to alter its performance.
Fibre screed, also called PP fibre or reinforced screeding, is excellent in any situation especially sites with high foot traffic. Polypropylene fibres (refered to as PP fibres) are combined with the sand and cement. The use of fibres reduces shrinkage and settlement cracking, increases strength, permeability and is more shatter and impact resistant. It can also be used over insulation and with under floor heating.
Reinforced screed is best for public sites that have to endure heavy loads and high foot fall. Galvanized wire mesh reinforcement is layered within the screed to improve its strength. It can be combined with other types of screeds to improve the floors performance.
Anhydrite screed, refered to as flow, poured and liquid screeding, is ideal for large, continuous spaces. It is self leveling and is poured directly onto a floor for a fast application. Anhydrite reduces cracking, is light weight, protein free and high strength. It can be used over insulation and with underfloor heating.
Fast Drying screed is a combination of sand, cement and an admixture such as Isocrete K-Screed, Ronacrete Uniscreed, Mapei Topchem, Knopp or alternatives. It is a specialist hydraulic binder which allows for rapid drying and will harden within 1 - 4 days depending upon depth and product type. It is suitable for interiors and exteriors and can be used over insulation and with underfloor heating.
Polymer Bonded screeds are ideal for concrete ground floor slabs, precast concrete, suspended floors and when a thinner depth is required. A polymer resin is combined with the sand and cement. The polymer resin is a high quality bonding agent in which a carboxylated styrene butadiene copolymer latex replaces conventional PVA. This increases durability, reduces shrinkage and cracking, increases flexibility and toughness, permeability and bonding strength. It can be used over insulation.
Latex Screed has increased strength and adhesion to the substrate. It is a synthetic rubber latex that improves adhesion of cementitious mortars and is based on synthetic polymers, which cannot be re-emulsified in water after hardening.
Lytag Screeding is a product that is added to the sand and cement. Lytag is a made from fly ash, which is a waste material from coal-fired power stations. The fly ash is added with water to form rounded pellets that are heated at temperature between 1000-1250°C. Lytag screeding is lightweight and fast drying, floor finishes can be laid within 24 hours. It also offers increased thermal and sound insulation.
