Waterproofing Membrane Between Concrete Slabs

A layer of waterproof or separation membrane is normally placed between sub base and concrete slab for the following reasons.

Waterproofing membrane between concrete slabs.

Tremproof 250gc is commonly used as a between slab on plaza decks parking decks roof terraces and podiums. These plates must be made of pressure. Sole plates or sill plates are the first pieces of framing lumber placed in home construction. It is ideal for repair maintenance or new construction applications.

At gravel beds adhesion is not possible so the bottom membrane may be loose laid with adhered joints. Underseal underslab membrane is a tough 85 mil pre concrete pour waterproofing membrane vapor barrier designed to virtually eliminate water and vapor transmission through concrete slabs on grade. When properly applied it will create a seamless membrane that will provide unsurpassed waterproofing performance and a longer life cycle than many other materials. Concrete waterproofing system provides an excellent waterproofing membrane for bridges parking decks or other vehicular traffic structures to be overlaid with an asphaltic concrete wearing course.

In addition to protecting floor finishes and indoor air quality underseal underslab membrane also acts as a barrier to methane and radon gas. Slabs protected from moisture that occurs by rain or snowfall and from moisture that might migrate upward from the ground. Between slab waterproofing usually utilizes an elastomeric polymer based membrane. I it prevents the loss of water from cement paste which affects the strength of concrete slab.

Gacoflex lm60 is recommended for use in irma roofing systems and on between slab and below grade structures. Over concrete slabs the membrane should be fully adhered. Gaco lm60 is 100 pure polyurethane. If additional membrane is required it should be adhered over the bottom membrane.

Moisture barrier between the sole plate the concrete slab. It is applied to the slab s surface typically as a spray coating. The tremproof 250gc is an effective membrane for use on concrete wood metal and masonry surfaces.
