Installation Systems

Flooring Installation Systems

There are several options when it comes to the installation system of a timber floor. These systems differ base on a number of factors including the product of choice, the sub-floor, and more. Below are the common system available to most timber flooring installations

You should discuss the following options with an NS Timber Flooring team member to identify the method that best suits your use and preferences, your budget, and the property’s structure.

Direct to concrete

The direct fixing method of gluing solid timber, engineered timber and other forms of timber flooring products to concrete involves using specially formulated adhesives to glue the product directly to the concrete sub-floor. It is important to note that many species and profiles of solid timber products are not suited to this form of installation. We can assist in selecting a product and species that suits this method.

Direct to concrete
Plywood over concrete

Using this method, a plywood sheet is mechanically fixed to the concrete slab over a .200um polythene moisture barrier. The floorboards are then fixed to the plywood by secret nailing. This method has a total profile depth of 34mm for 19mm thick flooring and 26mm for 14mm flooring.

Over a sheet floor

Similar to plywood over concrete, structural timber sheet floor is essentially a floor with a timber surface. This allows the floorboards to be fixed to the timber base by secret nailing. This method has a total profile depth of 14mm or 19mm thick depending on the flooring choice.

Over a sheet floor
Battens over concrete

This method is a series of timber battens fixed with masonry anchors to the concrete slab, over polythene sheeting at a spacing to suit the particular flooring product used. Solid timber tongue and grooved floorboards are then fixed to the battens (80×19 size board may be secret fixed, whereas 130mm and above must be top nailed). 35mm battens gives a total profile depth of 54mm. Another is a cost efficient 19mm batten can be used for a total profile depth of 38mm. 

A reducer may be required at the junction between the boards and lower profile flooring products (Carpet/Ceramic Tiles) used in the building. In a new building this difference can be more easily accommodated through a set down in the concrete.

Over existing timber floor

If you have an existing timber floor, the new floor can be installed directly over the top after an assessment of the existing floor is carried out.
