How to use a tenon membrane as a footing

Before erecting the foundation, it is necessary to prepare the foundation for it, the so-called podbetonku. The main task of concrete preparation is to properly distribute the load caused by the pressure of the soil, which eliminates its subsidence and prevents the flow of concrete milk from the foundation.

New technologies for the construction of structures require improvement and the use of modern materials. One of the methods of improving the device of concrete preparation is the use of a spiked membrane.

The spiked membrane SNT DRAIN is a high-quality material from the Turkish manufacturer Sintar.

• SNT DRAIN membranes are a rolled material made of high-quality high-density polyethylene (HDPE), on the surface of which spikes are staggered.
• Roll dimensions: 2x20 m.p. (40m.sq.)
• Membrane density: 400gr/sq.m., 500gr/sq.m., 600gr/sq.m.
• Spike height: 8mm

What are the advantages of using a spiked membrane in concrete preparation

• eliminates the waiting period for the hardening of the concrete layer
• cost savings from ordering special equipment, machines and concrete itself
• blocks the migration of concrete milk into sand preparation
• additional protection of the foundation from moisture
• the ability to perform work regardless of the weather (concrete can not be poured in heat, rain, at subzero temperatures)

You can start installing the fittings immediately after laying the membrane.

The usual podbetonka

• foundation plate
• concrete mix
• p/e film
• sand preparation
• ground

Concrete preparation with membrane

• foundation plate
• spiked membrane
• sand preparation
• ground

The technology of laying the footboard with a spiked membrane:

Preparation of a strong, well–compacted soil - leveling.

Roll out the membrane rolls over the entire surface with spikes up, connecting 10 cm overlap. Glue the overlap seams with butyl rubber tape.

That's it, you can start the following works: installation of the reinforcement frame and filling of the foundation plate.

The use of profiled spike–shaped membranes SNT DRAIN is a modern solution for the construction of a foundation plate with a reliable replacement of concrete preparation.
