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 enjoys 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 receive the flow from its subsidiaries.
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.
E-RETE Concrete Porous Pipes are manufactured to both the Malaysia Standard MS 525 : 1986 and British Standard BS 1194: 1969.
E-RETE Concrete Porous Pipes are produced from finest quality materials on up-to-date equipment by a combination of high frequency vibration and extrusion method.
E-RETE Concrete Porous Pipes are strong, highly porous and of consistant quality. They exceed by a large margin all tests as set out for porous pipes in the above two standard specifications.
E-RETE Concrete Porous Pipes have rebated or ogee joints formed from using a special mix to ensure alignment and prevent silt, roots, etc from entering the pipe line.
