IS IT RIGHT FOR THE JOB?

Damp Proof Membranes

Damp Proof Membranes are required to protect the screed and toppings from moisture. Various types of polythene are used to separate screeds and insulations from a damp substrate and generally used on ground floors to protect against rising damp. A 1200 gauge polythene is normally used in this instance and a 500 gauge is used as a separating membrane to ensure that the moist screed is separated from the insulation layer.

Radon Barriers

Radon Barriers are installed to deter Radon from entering a building by airflow from the underlying ground. There are passive and active methods of achieving radon protection. A passive system consists of an airtight radon proof membrane throughout the floors and walls and an active system that provides a natural or mechanical underfloor ventilation or a powered extract system as an integral part of the services system which will have active running and maintenance costs.

Primers

There are a whole host of primers that can be used as both a mechanical and chemical key as well as sealers. Many come as a system with specialist materials but can be used independently. Primers are a very important part of the bonding / sealing process and should always be incorporated into their correct applications. Standard primers for a mechanical key, consist of an SBR, cement and water mix where a screed is applied wet on wet. Chemical primers are generally more difficult substrates that are smooth and non-porous. Primers are generally applied with a brush or roller but specialist applicators may use airless sprays particularly on rough substrates. Always refer to a specialist contractor prior to application.

Accessories

Accessories such as flexible floor jointing materials, fibreglass fracture membranes, penetrating hardening systems, measuring jugs, buckets, brooms, shovels, protective high visibility barrier tapes, gloves, glasses, high visibility waist jackets, trowels, levels etc. can be purchased. Please call or fill in a contact sheet with your requirements. Due to our wide knowledge of the industry we have specialist products such as bio mixer protection, cleaners, retarders, frost protectors and many more.

CSC Screeding are members of Constructionline, CHAS and Builders Profile where a predefined Health & Safety questionnaire is pre-completed and our clients have direct access to the information. Documents contained in the pre-qualification system are updated throughout the year, ensuring continued compliance. We have focused on developing the business through constant innovation, implementation and collaboration.

We were an early adopter of FORS – gaining Bronze accreditation – as we recognised this would become more widely requested on construction sites.

We are now ready for the business to grow with the increasing demand.
