Blind Side Waterproofing

Blindside sometimes called pre applied is a term used to define the membrane type as well as the installation process.
Blind side waterproofing. Miraply combines two proven technologies to provide a one step compression seal gasket that combats shifting and soil separation from the foundation wall. Tremproof triple waterproofing system tws tremproof triple waterproofing system tws is a blindside and underslab triple layer waterpoofing assembly consisting of 20 mils of hdpe expandable granular bentonite and a protective layer of spun bonded polyester coated with 60 dry mils of polymer enhanced liquid applied asphalt membrane. It is crucial to ensure your system is not compromised by properly detailing areas susceptible to moisture intrusion as it can be very tricky to make any repairs after the fact. Many blind side below grade waterproofing systems include resistance to lateral water migration between the membrane and concrete as part of the manufacturer s design concept.
These layers provide dimensional stability but leave the edges which expose all of the laminate sections particularly vulnerable to water damage. Plywood is an important and stable building material comprised of many different veneers glued together at right angles. These use different glues to. Blindside waterproofing system for shotcrete foundation walls grace waterproofing products product advantages durable system designed specifically to withstand the force of shotcrete placement post injected grout fills and seals providing ultimate waterproofing protection aggressive bond to shotcrete resists lateral water migration excellent resistance to hydrostatic pressure.
Blindside waterproofing for horizontal applications involving a cluster of penetrations consider the use of hydralastic 836. Sealing plywood for longer life. Without lateral migration resistance water at a membrane breach may travel to remote cracks and penetrations in the foundation structure and into occupied space figure 1 thereby making the leakage source more. Blindside waterproofing can be a challenging but necessary and increasingly common method of below grade waterproofing.
It reverses the typical application the waterproofing is installed before the foundation is poured. Prior to application of hydralastic 836 prepare the surfaces of the penetrations as above and provide a block out using 2 x 4 6 x 1 2 m lumber or other in order to create a pitch pan area to receive hydralastic 836. Blindside is a positive side application meaning it goes on the outside or the soil side of the foundation wall.
