How do you ensure safe access for maintenance workers on a rooftop that has messy pipes, electrical conduits and frequent rain?

A large Tesco supermarket in the east of England needed a rooftop solution that would provide clear and safe passageways for maintenance workers to carry out essential tasks.

The problem

Like many other supermarkets of its size, the Tesco in Pitsea, Essex has a rooftop that’s covered in cables, pipes, slippery surfaces and surface units. With a steady stream of staff needing regular access to the roof, the building owners knew they needed to find an easy and safe way for maintenance engineers to access the roof without damaging the membrane.

The checklist

  • Loose laid, easy to install and have minimum maintenance over its life cycle
  • Remains stable in high winds and withstand extreme weather conditions
  • Quickly drains and dissipates liquids and debris
  • Resistant to bacterial growth and impermeable in all weathers.
  • Protects the roof membrane from damage

The solution

Creating safe walkways amongst the mass of cables and pipes was key, so the solution needed to be easy to install on a crowded roof, plus ensure extra traction underfoot. The answer was Crossgrip PVC, our specialised rooftop matting that's designed to be loose laid with no fixing required. Made from flexible PVC, it contours over uneven surfaces, including membrane seams, ramps and changes in levels, and is easy to cut to fit around obstacles.

Crossgrip's durable, two-layer construction protects the roof membrane, while the diamond-cut pattern and cross-directional top ribs ensures a firm under foot grip. The matting remains stable in winds up to 60mph (96km/h).

Highly durable, slip-resistant matting that provides safe access to the rooftop while protecting the membrane.

“Crossgrip has had a dramatic effect. In the winter time, even I was reluctant to go out onto the roof as the membrane was very slippery. Now we have safe access any time of the year and in all weathers. It’s made a big difference to us and the safety of our maintenance teams. The grip underfoot is very impressive and we feel a lot happier and safer negotiating the rooftop pipes, conduits and obstacles.”
