A strap drain material adapted for use in soil conservation in the hillside regions, in subterranean drainage for orchards and farmlands and in drainage system of the tunnels, road basement and basement of the buildings is formed on one surface of the flexible strap like or panel like body with a plurality of drainage grooves arranged parallel densely spaced-apart along the direction of the width and extending whole length along the direction of the length and including slit like openings capable of producing capillary action and interior channels expanding to form rounded holes. By the difference in water level at the two ends of the channels or the syphonic force so produced the capacity to absorb water is increased and water is collected and drained away. The interior of the part of the drain material where there is without drainage grooves is embedded with a plurality of longitudinally parallel arranged reinforcements of metal filament, synthetic filament or of crisscross network formed thereof. Also, on the two sides of the drain materials each is formed with a lap-joint part to provide for the adjoining drain materials to be connected in lap-joint manner and which has similar shape and is opposite in direction.
