Drybase TS-Plus 5-Bar Waterproofer is a liquid polymer additive designed to enhance Drybase TS-Plus Tanking Slurry, creating a superior waterproofing solution. This additive improves workability and adhesion, and has been successfully tested to withstand up to 5 bar hydrostatic water pressure. It is suitable for use on concrete and masonry, making it ideal for foundations, slabs, and retaining walls. The waterproofer is also resistant to salt efflorescence, making it a durable choice for areas prone to cracking. It can be applied using a trowel, brush, or spray, but it is important to note that it cannot be used alone and must be mixed with Drybase TS-Plus Tanking Slurry.
