Product

​Take a look and you will see what we're talking about! Delta is the only dimpled membrane in the market that is being manufactured in a co-extrusion process, utilizing virgin polyethylene on the outside layers and post-industrial recycled HDPE in the middle. Thus the product is significantly more resilient to environmental influences like oxygen, acidic soils or alkaline environments (concrete wall), etc.

DELTA®-MS is a highly effective foundation protection system, based on a uniquely shaped air-gap membrane. It reliably keeps ground moisture away from the foundation wall – a key factor in achieving a permanently dry basement.
