Quick tips
Waterproofing Preference: Choose bentonite sheet waterproofing where possible.
Alternatives to Bentonite: If bentonite isn't suitable, go for crystalline waterproofing or non-PVC thermoplastic sheet options.
When Using Asphalt-based Products: Opt for cold-applied asphalt emulsions. This is preferable over solvent-based products, self-adhering rubberized asphalt sheets, and hot-applied asphalt waterproofing.
Products to Avoid: Stay away from products that are mixed on-site, especially PMMA and polyurethane waterproofing.
Full Product Details: Always look for products that offer Health Product Declarations (HPDs) to understand their contents.
Additional Products: For adhered products, choose those that stick by themselves and either use a mechanical bond or non-bituminous/non-asphaltic adhesives.
