A new flooring solution was required as part of a large, high-specification self-build housing project on a country estate in North Berwick.

Underfloor heating had been specified for the ground floor of the house and it was important that the chosen floor solution would help to optimise heating efficiency.

Given the scale of the project it was also important that the chosen screed solution could be installed quickly over a large area to fit within the build programme.

The flooring contractor appointed to complete the work were based in the North East of England and regularly used flowing liquid screeds for this type of application.

Following initial discussions and a successful pump trial, the customer decided to use Tarmac’s TOPFLOW Screed C for the job.

TOPFLOW Screed C is a free-flowing cement based liquid screed that can be trafficked after just 24-48 hours and dries within 21-28 days. It can be pumped into place and allows large areas to be covered quickly with up to 120m2 laid in as little as 45 minutes.

Fast drying times mean it can be laid later in the programme when the building is fully water-tight and still hit deadlines for installation of flooring.

It is ideal for use with underfloor heating systems. As a self-compacting screed, it fully encapsulates heating pipes without leaving any voids and is also a more conductive medium than traditional sand and cement screeds, improving the thermal performance of the system.

It is also compatible with the most cement-based adhesives, meaning it can be used with a wide range of flooring types.
