Hydrostatic and Gas Vapor Barrier Systems

Waterproofing is critical to the long-term structural integrity of a building. Water and gas vapor infiltration is typically difficult to access and extremely difficult to remedy, resulting in it being the leading contributor to construction defect litigation. Preventing infiltration starts with proper design, good construction practices and paying attention to material selection. It is important that the durability of the design and materials selected for a below-grade application be built to approximate the overall service life of the structure.

The Design StageTremco Commercial Sealants & Waterproofing is uniquely qualified to assist in the proper selection and specification of products to provide comprehensive solutions for even the most demanding below-grade applications. Experienced, knowledgeable field sales representatives in every major market across the United States and Canada coupled with the technical expertise of our Technical Services Group provide assistance with material selection, specifications, system design, testing and on-site support.

Approved ApplicatorsApplicator training and experience is extremely important and Tremco local field sales representatives have worked with a select group of approved applicators who have made a commitment to quality installation of below-grade waterproofing and have experience on the most complex projects. These applicators have been trained by Tremco on waterproofing system installation and also by the manufacturer of the heat welding equipment for treatment of seams.

Tremco field sales representatives are available to attend pre-construction meetings, mock-up assistance and o�er on-going training and on-site support to

help eliminate guesswork and uncertainty. Additionally, Tremco can recommend third-party inspection firms who are knowledgeable and experienced with Tremco systems for additional support.

Independent Third-Party Inspections Any number of factors can impact below-grade installations and work of subsequent trades, such as expedited schedules, construction traffic and exposure to the elements for extended periods. To avoid the potential for a problem down the line, monitoring by an independent third-party inspector can ensure compliance with project requirements during installation and during subsequent work being done by other trades. Inspections should include sign-o� by consultants or other appropriate parties on any seams for ultimate assurance of watertight performance.

MaterialsFew manufacturers can provide comprehensive waterproofing solutions including e�ective terminations and connectivity to above grade conditions. Waterproofing and/or gas mitigation

protects the integrity of a structure and its occupants by forming a continuous barrier that prevents water and gas from entering the building envelope and occupied space. In order to eliminate potential sources of water and/or gas infiltration there must be continuity, without areas of weakness, such as at transitions or penetrations. Connections must be able to accommodate any normal movement of the building structure. Of critical importance is any incompatibility between the membrane, detailing and any connecting components which can result in membrane failure and ultimately lead to water infiltration.

Tremco Commercial Sealants & Waterproofing o�ers comprehensive building solutions from below-grade to the roof. Products are formulated and tested to ensure long term performance not only in laboratory settings but real-world conditions where they may abut, adjoin or overlap with other components or systems.

Products

Membrane: Paraseal GM/LG 60-mil HDPE Membrane is a composite sheet waterproofing membrane that combines a 60-mil layer of high-density polyethylene with expandable, quality granular bentonite. Installed as a system with heat-welded seams, a superior Dual Waterproofing and Gas Barrier Membrane System is engineered for application to both horizontal and vertical surfaces.

Detailing, Connections and Drainage: Para JT Tape is an adhesive joint tape compound formulated with cross-linked polymeric elastomers.

Paraseal Paraterm Bar is an aluminum alloy fastened through pre-drilled holes which is specially profiled to provide excellent holding power.

Superstop Resealable Bentonite Waterstop Material is a multiple composite used to seal cold joints in concrete combining the strength and toughness of conventional waterstop with the self-sealing ability of bentonite to prevent water migration in joints.

Paramastic is an expandable mastic for use with Paraseal waterproofing membrane.

Paragranular is a premium, high swelling, granular sodium bentonite. It is used to form a cove at all horizontal to vertical transitions, at floor/wall transitions and penetrations through horizontal surfaces and to fill voids around irregularities.

Dymonic 100 is a high performance, medium-modulus, low-VOC, UV-stable, non-sag polyurethane sealant, that has excellent movement capability and will adhere to damp and green concrete.

Parastick ‘n’ Dry is a laminate of bentonite applied to mesh with a pressure-sensitive adhesive on one side which can be used with Paraseal and Paramastic to assist in waterproofing difficult areas such as soldier piles and to wrap pipe penetrations and concrete imbeds.

TREMproof 250GC T (trowelable) is a single component, rapid curing, VOC-compliant, fluid-applied waterproofing membrane which is suitable for use for cants and around penetrations. (3 grades available: Self-leveling, Roller, Trowelable)

TREMDrain Series is a family of drainage mats with a variety of combinations of filter fabrics, drainage cores and protective polymeric film.
