Pre-Applied Waterproofing Systems

Pre-Applied Waterproofing Solutions that meet your risk tolerance

One size does not fit all for pre-applied waterproofing jobs. What tips the scale for one solution over the other? Risk tolerance. Building use, geotechnical conditions, soil type, and groundwater levels affect risk tolerance. Evaluating these determines the required protection level and the appropriate waterproofing membrane. Henry offers pre-applied waterproofing solutions for high, medium, and low-risk levels.

Protect your investment with the right product choice

Choosing the right waterproofing membrane is critical in safeguarding building envelopes and mitigating potential damage. For over 80 years, design professionals and contractors have relied on Henry waterproofing solutions to minimize or eliminate property damage caused by water leaks, saving building owners from significant financial losses.

Combining mechanical and adhesive bonds to help reduce lateral water migration

Blueskin PreSeal membrane is a pre-applied, fully and permanently bonded sheet membrane system for waterproof construction. The membrane's unique dual bond enhances adhesion, minimizes or eliminates lateral water migration, reduces membrane penetration, and mitigates sequencing delays related to chemically bonded systems.

Features and Benefits

Easily installs with self-adhering laps and splices – no special tools or torches required
Highly resistant to harmful substances in soil and groundwater, as well as superior resistance to water vapor and radon gas
Better cold weather performance than HDPE systems for excellent low temperature flexibility and crack bridging
Living Building Challenge (LBC) Red List Free status supports sustainable building properties

Durable and easy to work with

BlueSkin PreSeal is designed with a rugged cross-laminated, high-density polyethylene film that offers superior puncture and tear resistance. Installed prior to rebar installation and concrete placement, it features wide rolls resulting in fewer seams. On the jobsite, the system’s lightweight rolls are easy to transport, cut and position, making installation fast and easy.

The perfect solution for high-risk projects where water tables are high and replacing building contents is costly

MiraWELD is an adhesively bonded pre-applied waterproofing solution with welded seams that is typically used for high-risk projects like hospitals, museums, and computer centers. It is best used for below-grade applications on foundation walls and under slab where the groundwater is a concern and removing and replacing sensitive interior finishes and equipment would be costly if water intrusion were to occur.

Features and benefits

The only self-adhering, pre-applied waterproofing membrane and weldable system on the market. (US Patent No. 10710344)

Easy to install using weldable prefabricated detailing accessories

Adhesively seals to the structure, resisting water intrusion and lateral water migration

Superior puncture resistance compared to self-adhered pre-applied membranes by others

Chemically resistant to common groundwater and soil contaminants, and resistant to radon and methane

Unaffected by inclement weather and wet-dry cycling. Does not require confinement/constant pressure to perform

Time-tested technology where durability, puncture resistance, and reliable performance are critical factors

MiraPLY is a patented, self-adhering waterproofing system which fuses the time-tested waterproofing qualities of TPO and the self-sealing properties of butyl alloy adhesive. The fully adhered system features a 45-mil thick, reinforced TPO sheet laminated to a 25-mil butyl adhesive coating. Factory installed SeamLOCK pre-primed, peel-and go-strips eliminate the need for primer saving time without compromising the membrane’s exceptional adhesion.

Features and benefits

Adhesively seals to the structure, resisting water intrusion and lateral water migration

Superior puncture resistance compared to other self-adhered pre-applied membranes

Chemically resistant to common groundwater and soil contaminants, and resistant to radon and methane

SeamLOCK Technology with dual self-adhesive selvedges results in exceptional seams

Unaffected by inclement weather and wet-dry cycling

Does not require confinement or constant pressure

Bentonite clay waterproofing system helps absorb large amounts of water and expand to create an impenetrable barrier

MiraCLAY is a bentonite clay waterproofing system that is a widely used, cost-effective solution suitable for below grade applications. MiraCLAY panels consist of two layers of geotextile fabric that sandwich a layer of sodium bentonite clay, which swells or hydrates in the presence of water and creates a gasket seal.

Features and Benefits

High shear construction Impermeable waterproofing barrier when hydrated
Self-sealing when punctured or penetrated
Flexible around corners and irregular substrates
Resistant to most chemicals; non-toxic, non-polluting, no fumes
Economical and installer friendly
Cold weather application
Hydrated panel edges prevent material loss during installation
Compatible with contaminated ground water (salt or chemical)
