Redwood timber anti-slip decking with two rubber crumb inserts of 1–3 mm black ethylene propylene diene monomer (EPDM) rubber and a 1–4 mm coloured EPDM. This allows rainwater to permeate through the board, back into the water course below. Traditional rubber infill decking boards can retain water, resulting in algae growth and water freezing in the board.

Gripsure Aquadeck™ is available in various colours and is an alternative solution to aggregate filled anti-slip decking boards. The rubber crumb infill is soft underfoot and the dual drainage channels allow surface water to drain away.

Features and benefits:

  • Permeable surface.
  • Made from high-quality, slow grown Redwood timber, with smaller live knots.
  • Close grain of the timber provides good working properties for machining to profile and is less liable to splitting or cracking.
  • The moisture content and cell structure of the Redwood timber allows better penetration of the preservative treatment.
  • Profile designed to retain the central timber strip.
  • Rubber crumb infill has high slip resistance and is soft underfoot meaning it is less abrasive in the event of a fall.
  • Colours can be used as a solid infill or mixed to create a flecked effect.
  • Low maintenance, no further preservative treatment is necessary.
  • Vacuum/ pressure treated to meet the requirements of Use Class 3.2 (BS EN 335), which gives an expected in-service life of 15-years.
  • Also available with preservative treatment to Use Class 4 for an expected in service life of 25-years and a preservative treatment that complies with the Highways Agency Sector 4 Scheme which gives an expected life of 30-years.
  • Pressure washable.
  • Operated to the United Kingdom Slip Resistance Group (UKSRG).
  • FSC® certified timber.
  • SuDS compliant.


Suitable for a number of residential and public sector applications where safety is a concern and in commercial developments, including:

  • Schools.
  • Playgrounds.
  • Retail outlets.
  • Hotels and restaurants.
  • Leisure and tourism facilities.
  • Pool areas.
  • Hot tubs and spas.

Any cuts, notches or drill holes to the decking during construction must be treated with an end-grain preservative to maintain the integrity of the treatment, and the in service life.

Stehle 250 x 30 mm bore Z=16 2.2 mm width PCD (poly crystalline diamond) saw blade is recommended for cutting the timber and inserts. Alternatively the decking board can be cut using a regular cutting blade, conventional hand saw or chop saw.

Gripsure do not recommend painting or staining Gripsure Aquadeck™ – however, it can still be stained or painted. Water repellent sealant can be applied every 12-months to give extra protection to the timber – consult manufacturer for further details.
