CONCRETE POROUS PIPES

General

The use of E-RETE Concrete Porous Pipes for under drainage is a great advantage in both efficiency and economy. Their strengths are much greater than the ordinary clay subsoil pipes, and INCREASE WITH AGE, remaining unaffected by the absorption of moisture.

The unique property of concrete porous pipes is that infiltration of water takes place over the entire surface. A concrete porous pipe underdrain enjoy the best characteristics of a rubble drain with the additional advantage of a central duct for rapid removal of water. The porosity is so remarkable that small drains may be connected to larger ones merely by placing the end of the former over the latter without the need for piercing the wall of the main to enable it to recieve the flow from its subsidiaries.

Application

E-RETE Concrete Porous Pipes are being used under road verges and railway lines for subsoil drainage and the removal of surplus water. Porous pipes are used extensively for aerodrome drainage due to its adequate strength to withstand inpact load from air craft. They may be widely spaced, thus saving in cost and a minimum surface disturbance; and as the continuous inflitration principle banishes the possibility of subsidence, the risk of dangerous depressions in the surface of the aerodrome over the drainage system is absent.

E-RETE Concrete Porous Pipes are used extensively on Highways, Housing Sites, Aerodromes, Recreation Grounds, Race Tracks, Agricultural Land, Tennis Courts, open grounds. etc. They ensure rapid removal for all surplus water, yet by capillary action, retain sufficient moisture in the soil to promote a healthy condition of the turf.
