Swelltite - Composite Bentonite Waterproofing System
A highly effective waterproofing membrane, SWELLTITE consists of a sodium bentonite compound integrally bonded to a geomembrane liner. This composite combines the active waterproofing benefits of sodium bentonite with the strength and durability of a thick geomembrane liner.

SWELLTITE is a true advancement in waterproofing membrane technology. Unlike other membrane systems, SWELLTITE’s reactive bentonite compound can expand to seal small punctures in the membrane. SWELLTITE is manufactured at a factory controlled thickness of 2.0 mm (80 mils) assuring the specifier, contractor, and owner of consistent material application. This engineered composite consists of a thick geomembrane liner and bentonite compound with a clear release film attached. SWELLTITE contains virtually zero VOC, can be installed to green concrete, and most importantly, has proven effective for more than 20 years.
SWELLTITE is designed for below-grade vertical and horizontal structural foundation surfaces, as well as, above grade split-slab construction. Typical below-grade applications include backfilled concrete walls, masonry block walls, earth-covered roofs, and tunnel roofs. Typical above grade split-slab construction applications include plaza decks, parking decks, and balconies Additionally, SWELLTITE can be used for interior split-slabapplications for mechanical rooms, kitchens, and laboratory facilities. Applications may include structures under continuous or intermittent hydrostatic pressure.
General: Install SWELLTITE and accessory products in strict accordance with the manufacturer’s installation guidelines. Install SWELLTITE with the bentonite compound directly against the substrate to be waterproofed. For ease of handling, the sticky bentonite compound is covered with a siliconized release film that must be removed during installation. Schedule waterproofing material installation to permit prompt placement of backfill material or concrete. For applications not covered herein, contact CETCO for specific installation guidelines.
Storage: Store SWELLTITE and accessory products in a dry location protected from construction operations and weather. Protect materials from moisture, excessive temperatures and prolonged exposure to direct sunlight during storage. When storing materials outside at a jobsite, provide weather-proof covering, top and all sides (allow for adequate ventilation). Do not double stack pallets in storage or during shipment.
Preparatory Work: Structural concrete surfaces should be smooth and free of dirt, rock, debris, oil, grease, laitenance, or other foreign materials. Remove form fins and other protrusions to match substrate surface. Completely fill any Form-tie holes, honeycombing, voids, and cracks with non-shrink cementituous grout, M-2000 or BENTOSEAL. Concrete surfaces to receive M-2000 Liquid Flashing should be water cured a minimum of 7 days prior to application. Where possible, design horizontal concrete surfaces with proper slope to drain.
