Tag: Anhydrite Screed in Reading

If you are going to lay flooring in a building, and most people do (!), it obviously needs to be as flat as possible for people to walk on, perhaps push a push-chair over, or maybe you are building a skate park and people are going to skate on the final floor, but whatever, it needs to be flat.

When constructing a new building, or carrying out a major renovation, one of the most important considerations is the floor. It may seem obvious, but everything and everybody is going to be standing or walking on that floor and it has to be both safe and sound, and level.

One of the most critical parts of any construction project is making certain that the substrate upon which the final flooring is going to be laid is as flat and level as it can possibly be. The usual answer is to lay a screed on top of the concrete in order to produce a level surface, and the ideal is the measurement SR1 – Surface Regularity 1. SR2 is fairly good, although not perfect.

For many years, the traditional screed has been made of sand and cement and has been laid with a trowel. This has many disadvantages, not the least of which is when underfloor heating is going to be installed as well. Laying a sand and cement screed is also a long-drawn-out job, being installed as it is by a man on hands and knees.
