Durable Construction Temporary Road Mats Made of Recycled Polyethylene for Agricultural Roads and Working Platforms


Repy Board® & HELIBOARD®; Ideal Solutions for Farmers to Access Markets Even in Rainy Season  
Repy Board® (plastic ground plate) is manufactured from recycled polyethylene, which size is 1,230×2,200×13mm. HELIBOARD® (portable helipad) consists of a combination of Repy Boards®. These boards are quite rugged, but so lightweight that it is easy to transport and install by hand, without any assistance of heavy machines.

Technology Data

Possible applications

Repy Board® is ideal solution for construction of rural roads. Road surface of Repy Boards® remains rugged enough to support traffic of vehicles for 30+ years. Roads of Repy Boards® enable farmers to access markets even in rainy season, which helps motivate farmers for more production and income to get out of poverty. The following photos illustrate examples of use.

HELIBOARD® is an ideal helipad in developing countries where heavy equipment is rarely available. Rural areas are prone to natural disasters. In such an event, helicopters are deployed to transport first-aid team to inaccessible locations for aid to victims. Helipad is essential for safe flight of helicopters, and HELIBOARD® can be installed within a couple of hours.

Competitive advantage

For construction of rural roads, Repy Board® is much more advantageous than concrete/asphalt both in cost and time. Repy Boards® require no heavy equipment for installation. Repy Board® has long service life of 30+ years, which helps to save cost for maintenance.

Helipad is conventionally made of aluminum, stainless steel or concrete. HELIBOARD® is not as aesthetic as such helipads, but is equivalent to those helipads in practical use. In consideration of the lifespan of HELIBOARD® of 30+ years, HELIBOARD® is far better than conventional helipads in terms of cost performance.
