Delta sealed systems are recommended for below ground waterproofing where soil is retained, for example, basements and vaults.

Membrane selection depends on the required finish and flow rate if applicable. All membrane junctions, fixing points, service entries and other protrusions are sealed with the Delta Seal range of sealing products. Where active ground water is evident or expected drainage of one form or another should be incorporated into the specification. Delta technical staff provide full technical support and advice.
