Description  :

Atal Flo Board 4e consists a high strength flexible polyethylene cuspated core with a non-woven geotexHle bonded onto one or both sides. The geotexHle filters a wide range of materials allowing water to perculate into the core to be efficiently transported away to a discharge point. The geotexHle is bonded to the core to ensure that it does not deform into the drainage passages under the load of the backfill material allowing conHnuity of the drainage void. The single cuspated HDPE core forms a high-performance drainage layer with clear void to allow flow in all direcHons. The compressive strength and creep resistance properHes of Atal Flo Board 4e ensures that the core maintains its drainage capacity, even when subjected to compressive loads. Atal Flo Board 4e is durable and sufficiently robust to resist the mechanical stresses imposed during installaHon and throughout the design life.
Use of Atal Flo Board 4e will eliminate the need for further protecHon of the waterproofing.

Advantages :

When compared with aggregate drainage layers Atal Flo Board 4e
geocomposites are much thinner yet offer superior flow characterisHcs. This reduces dead loads associated with aggregate drainage layers and may reduce required thickness of the roof slab construcHon. The wide roll Atal Flo Board 4e composites are especially suited for rapid installaHon on large block paving or roof drainage projects. Atal Flo Board 4e enhances structural waterproofing performance by providing an addiHonal barrier that prevents the majority of the water reaching the liner.
The high CBR puncture resistance of Atal Flo Board 4e provides protecHon and prolongs the life of the waterproofing.
