Trowel Applied Screeds

 

Traditional sand and cement has been the most common type of floor screed for the past 50 years

Benefits include:

  • Cost effective
  • Can be laid bonded, unbonded or floating
  • Popular for use over under-floor heating systems where the pipes are fully encapsulated

Fibre reinforced screed incorporating polypropylene fibres

Benefits include:

  • The fibres help reduce the risk of plastic shrinkage cracking (replaces previous methods such as D49 mesh or Chicken/Hex Wire)
  • By improved residual strength and durability this screed has a high resistance to impact, shatter and abrasion

Polymer modified floor screeds are traditional sand and cement floor screeds incorporating water based polymer emulsion

Benefits include

  • Emulsion increases the bond strength of these screeds allowing them to be laid as little as 10mm thickness
  • They have an improved physical, compressive, flexural, tensile and abrasion resistance
  • When granite chippings are incorporated into the mix, the polymer screed becomes a wearing finish floor

Proprietary Screeds such as Isocrete K Screed, Flexidry Floor Screeds, Tarmac Truscreed, Mapei Topcem, Ardex A35 and EB2 are modified versions of traditional sand and cement screeds

Benefits include

  • Valuable where speed of curing and hardening are of paramount importance on fast track construction projects
  • All can be used in conjunction with under floor heating systems

Lightweight floor screeds where the most common is Lytag, a base layer of lytag floor screed is laid then topped off with a sand and cement screed

Benefits include

  • Popular for use on roofs and buildings where weight is a concern
