Deck sheets are designed to butt join with the ribs of the profile lined through to avoid gaps and minimise grout loss.

Metal deck is not intended to provide a watertight solution, therefore small quantities of grout and water loss are inevitable. Gaps in excess of 5mm should be sealed using either tape or expanding foam. Generally, gaps less than 5mm are acceptable with no special provision as they are too small to allow aggregate to escape, although grout loss will occur.

If the soffit and trim is intended to be fully exposed in its final condition, consideration should be give at tender stage to the taping of all joints prior to concreting or alternatively jet-washing the underside of steelwork post concrete pour.

The use of needle head vibrating pokers is not recommended as these can encourage greater grout loss.
