An important and critical item in tank building is the connection between the tank wall and the foundation, because of the link of two different materials and different characteristics….

Enameled elastic steel meets brittle concrete.

Usually the enameled steel sheets are set down in a large groove, which is a part of the foundation. This groove will be sealed with concrete later.
This groove is later on, filled with concrete by the customer. The responsibility of the tightness goes from the tank-erector to the client.
By the subsequent concrete-grouting , leaks are a inevitable result, as there is no bondage between old and new concrete and enameled steel-sheets.

Also the set down of the tank wall to a flat and smooth foundation without any groove is problematical.

The concrete slab is never perfectly flat, and it always remains a gap between concrete and tank wall. This gap is usually closed with sealing material.

The tightness of the heavily loaded foundation connection relies solely on the sealing material. This is problematic because the sealant manufacturers don’t issue long lasting guarantees.

For that challenge, we developed the GLS Tanks ring-groove system.

In the prepared foundation, we cut a small 4÷5cm deep ring-groove. We set down the tank-wall into this ring-groove, unevenness of the concrete slab will be compensated.

Then the ring-groove is poured-out with a reactive epoxy-resin sealant.

This joints the enameled steel panels to the concrete(base).

Thus, we do have a 100% durable and guaranteed tightness from the wall to the floor.
