Construction work, well sealing, drainage ditches
and moisture absorption

A comparison with other sealing materials shows
that DantoGran 0 - 30 mm is the safest method
of well sealing:

Advantages of bentonite sealing

• 100% pure natural product. • Membrane follows shape of substrate.

• Superior when sealing foundations and penetrations • Total establishment costs are kept low.
in lakes, canals and stormwater reservoirs.
• Laying out the membrane is a simple procedure.
• Long-lasting solution.
• Can be laid using ordinary construction equipment.
• No bonds/joints or leaks around penetrating pipes.
• The membrane is significantly denser, more robust
• If the membrane is damaged, it will repair itself. and flexible than traditional plastic membranes.

• Water cannot get under the membrane
and create bulging.
