Sulphate attack on concrete floor

[anth6568]

I am looking at buying a house and the front room has a problem with its floor.

The concrete floor has risen by 100mm and now needs to be replaced.

An engineers reports has been recently with directions on how to fix.

The room is 3.6m by 3.5m.

I was wondering if anyone knew how much this would cost?

Regards

Hello

The Engineer said the follow:

The Property has been affected by an uplift in the concrete ground bearing floor slab. The damage is not due to subsidence and has most likely been caused by the presence of an expansive fill material beneath the slab.

Due to the degree of the uplift it is unlikely the floor can be satisfactorily re-leveled. It will, therefore, be neccassary to break out the slab, remove the contaminated fill from the site and replace with new uncomtaminated fill, such as DOT tpye 2 roadstone,laid in compacted 300mm layers.

A new concrete floor using sulphate resisting cement and incorporating a 1,200 guage visqueen damp proof membrane should then be laid ensuring the new damp proof membrane is made continious with the D.P.C in the walls.

Hope this helps?

Regards
