PENEFOL® 800

Well-tried LDPE membrane protects against chemical, radon and aggressive ground water.

PENEFOL ® 800 is a long-term proven chemically resistant membrane. It is commonly used as a radon barrier up to medium risk.The most commonly used thickness is from 1.5 to 2.0 mm. To correctly determine the specific value, you need to make a calculation based on the radon index measurement and the layout of living rooms in the basement or on the ground floor - that is, on the floor that comes into contact with the soil. Based on the measurement results, we recommend a suitable membrane.

The PENEFOL ® 800 LDPE membrane is also used as a good waterproofing of the house. It is solid and serves as a barrier against aggressive groundwater and against the growth of roots.

PENEFOL ® 800 in practice

Insert LDPE membrane into the structure. Protect its both sides with IZOLTECH H geotextile to avoid UV light. Individual strips are connected exclusively by hot-air or hot-wedge welding, without use of open flames.
