Masonry construction

Subfloor Preparation
The building must be weatherproofed and wet trades completely dried out before commencing installation of flooring components. Isolated high points, mortar spillages and other debris should be removed from the area. All joints between concrete units and at perimeter walls must be grouted. Excessive moisture from cast insitu slabs and screeds which have not dried out can have adverse effects on flooring materials and timber components. BS 8201 : 1987 states that “it is reasonable to recommend that the concrete be considered dry when the relative humidity falls to 75% or less” (when tested by use of a hygrometer). Where the dryness of concrete cannot be guaranteed it is recommended that a vapour barrier is installed (minimum 1000 gauge).

Areas of Heavy Loading
In areas where heavy loadings are anticipated (such as kitchens and bathrooms) centres should be reduced to 300mm between the Danskin Reflex Bearers to provide additional support. On areas of concentrated loads such as beneath baths, W.C.’s and kitchen appliances Danskin High Load Bearers can be supplied to provide additional support. High Load Bearers should only be used for isolated support and not laid in general areas as they do not provide acoustic insulation.

Partitions
Partitions should normally be erected from the subfloor. Where lightweight non-loadbearing partitions are built from the top of the floating floor a double row of Reflex Bearers should be placed directly below.

Perimeter Bearers
Place Danskin High Load Bearers around the perimeter of the room approximately 50mm away from the wall.
