ESTERDAN 48 P ELAST

About this product

ESTERDAN 48 P ELAST is a waterproofing bituminous sheet with non self-protected surface of 4.8 kg/m².

Composed of a non-woven polyester felt reinforcement and covered on both sides with SBS modified bitumen mastic. A polyethylene film is used as anti-adherent material on both sides.

Tested according to standard EN test methods.

Underlay for self-protected double-layer bonded membranes.

Bottom or top sheet in two-ply membranes with heavy bonded protection).

Bottom or top sheet in two-ply membranes with heavy unbonded or floating protection.

Bonded single-layer membrane for the waterproofing of roofs with heavy protection.

Bonded single-layer membrane for waterproofing slabs and foundation slabs with hydrostatic pressure.

Bonded single-layer membrane for waterproofing wet areas (bathrooms, toilets, changing rooms, etc.) in all types of buildings.

Unbonded or floating single-layer membrane for the waterproofing of roofs with heavy protection.

It can replace the Esterdan 40 P Elast sheet in all systems where this sheet is used, especially when the durability of the waterproofing membrane is to be improved and the installation of the sheet is to be facilitated.

Tanking membrane.

Good performance in nailed systems.

It has a nominal mass of 4.8 kg/m², which is higher than the 4.0 kg/m² of LBM-40-FP). The higher mass of plastomeric bitumen increases the durability of the waterproofing and makes it easier to lay the sheet.

A membrane for instances where high waterproofing performance is required.

Suitable for zero fall roofs (see related certificates).

The sheet, being made of a bitumen mastic modified with SBS-type elastomeric polymers, substantially improves other bituminous mastics, providing much better performance in terms of reaction at high and low temperatures, elasticity and resistance to ageing, which leads to greater durability of the sheet and greater safety of the waterproofing membrane.

Has good piercing protection from possible mechanical damage, derived from the occasional pedestrian traffic typical of flat roofs.
