Timber decks continue to be an increasingly popular choice for a variety of both commercial and domestic applications.  However, many conventional deck boards can become slippery in wet conditions and hence present the danger of slips, falls and personal injury.  John Brash has long recognised this problem and the need to proivide enhanced grip for certain applications.

 

JB Antislip Plus® has been specifically designed to provide a durable and effective external antislip surface to minimise any risk of slipping - even in adverse weather conditions.  JB Antislip Plus® uses a unique formula of resin based aggregate inserts which are injected into the deck board grooves.  If smooth boards are required, grooves are specially machined into the boards to receive the inserts. 

 

John Brash recommends the use of JB Antislip Plus® for all decks where there is public access or where there is an anticipated high level of pedestrain traffic.  JB Antislip Plus® is also recommended for all stairs and ramps.

 

JB Antislip Plus® is available in treated Softwood (Decksure®), ThermoWood® and Western Red Cedar.  Hardwood is available to special order only.

 

 

John Brash has developed the JB Antislip Plus® insert in-house and have their own production facility.  Complete control is taken at all stages of the production process.  John Brash runs the production within their ISO 9001 quality assurance scheme. 

 

JB Antislip Plus® has been independently tested by the Health and Safety Laboratory (HSL) using a Stanley Pendulum Test (the operation and calibration of which are described in BS7976:2002 parts 1 and 3) operated to the current issue# of the United Kingdom Slip Resistance Group (UKSRG) guidelines (Issue 3, 2005).

 

The samples were tested with Slider 96 Rubber, also known as Four-S Rubber (Standard Simulated Shoe Sole), which was developed to represent a footwear material of moderate performance. Using Slider 96 Rubber, the Pendulum Test Values (PTVs) achieved significantly exceed the minimum required classification for ‘low potential for slip’.  Under the UKSRG guidelines, a surface is required to have a PTV of 36 or above to be considered to have a ‘low potential for slip’.

 

 The results of the HSL test are as follows:

 

JB Antislip Plus® with 2 inserts: Average* PTV = 63 when wet (27 above required standard)

JB Antislip Plus® with 3 inserts: Average* PTV = 69 when wet (33 above required standard)

 

JB Antislip Plus® with 2 inserts: Average* PTV = 78 when dry (42 above required standard)

JB Antislip Plus® with 3 inserts: Average* PTV = 81 when dry (45 above required standard)

*Testing carried out using castellated (grooved) boards to a variety of different orientations.

For most uses 2 antislip inserts are appropriate, however there are instances where 3 inserts should be used, for example on a public walkway which crosses water.
