Waterproofing Membrane Under Concrete Slab

Meadows is your moisture protection solution.

Waterproofing membrane under concrete slab. Meadows pre applied underslab waterproofing membrane is demonstrated by the fact that architects and contractors continue to trust it for their biggest projects. Waterproofing membranes installed under concrete slabs must provide permanent vapour gas chemical water protection. Once concrete is poured against precon and the concrete cures a mechanical bond forms that secures the concrete to the membrane. Under slabs or behind basement walls on confined sites require a waterproofing membrane system that bonds robustly to the concrete block wall.

In this rogue episode matt will show you a method to waterproof this very tricky transition between a wall and flat concrete slab. The effectiveness overall efficiency and hiqh quality of precon w. Liquid rubber is suitable for old or new concrete slabs brick and ma. For 2019 consider precon for all your building envelope.

Membranes are located either directly beneath the concrete or under a graded compactable granular blotter what s at stake is the amount of curling that can occur when mix water leaves the bottom of a slab slower than it does on the top surface. In addition to protecting floor finishes and indoor air quality underseal underslab membrane also acts as a barrier to methane and radon gas. The traditional plastic barrier used for under slab protection is a moisture barrier and is not a waterproof membrane. The under slab waterproofing should project 9 to 12 inches beyond the foundation so that the vertical membrane can be turned out over the exposed toe of the horizontal surface.

All waterproofing videos. Uses precon is used as a blindside membrane in vertical applications where access to the positive side is limited. Many conventional non adhering moisture barrier membranes are vulnerable to water ingress tracking between the unbonded membrane and sub structure.
