Installation Service The installation should be carried out by a Flowcrete approved contractor with a documented quality assurance scheme. Obtain details of our approved applicators by contacting our customer service team.

Substrate Requirements Concrete or screed substrate should be a minimum of 25N/mm2, free from laitance, dust and other contamination. The substrate should be surface dry to 100% RH or less (as per BS 8204) before the application of Flowcem. Note: Flowcem is not designed to resist hydrostatic water pressure. In such circumstances external tanking or pressure relief, e.g. by directed drainage, must be provided to the structure.

Environmental considerations The finished system is assessed as non-hazardous to health and the environment. The long service life and seamless surface reduce the need for repairs, maintenance and cleaning. Environmental and health considerations are controlled during manufacture and application of the products by Flowcrete staff and fully trained and experienced contractors.

Life Expectancy Flowcem is in practice a permanent membrane to protect final finishes from moisture related damage for the life of the floor, subject to there being no structural movement nor failure of the concrete slab, no severe thermal cycling nor exposure to
