Floor slabs collect moisture and mold when composed of porous concrete. In order to protect a building’s foundation and provide longevity, proper moisture control is necessary. A sub-base course will protect the footing and prevent the concrete from drawing moisture up from the dirt, which would allow it to seep through the slab.
DELTA®-MS 20
The Problems
The Solution
DELTA®-MS 20 is a compression-resistant, durable, dimpled sheet made from special High-Density Polyethylene (HDPE). It provides heavy-duty, long-term protection for permanently dry foundation.
This product is a heavy gauge version of DELTA®-MS with deep 20 mm studs. It is used where extra drainage capacity is required, on deeper structures or where a larger flow rate is required, for example. DELTA®-MS 20 can also be used as a “cavity former” for many types of new construction.
Product Details
Product Benefits
- Studded membrane composed of HDPE
- 20 mm studs create an air-gap at the foundation base, creating a free drainage path, allowing any water that gets past the dimpled plastic sheet to fall freely to the footer drain
- High drainage capacity
- Impermeable to water and water vapors
- Impervious to acids and other agents
- Tough, resilient, and durable – has an expected service life of more than 50 years
- Unlike a coating, product bridges all size cracks, ignores damage points, and deflects water
