Looking at the fibrous paints or other low cost solution
Sounds identical to one I did myself once. IIRC I used bitumen paint as
a cheapo solution, as I knew I'd be selling the place not long
Seemed to do the job well enough; I can't vouch for it's longevity but
think if I'd been intending on keeping the property for a long time I'd
have chosen something more durable. Indeed, the purchaser's surveyor
flagged it as a future maintenance issue.
yeah. Concrete itself is pretty impervious, depending on the grade.
Anything that soaks in a bit of a plasticky or tarry nature will improve
Probably one of those render waterproofers will do.
good thoughts I will investigate further as I think that the problem is a
crack in the concrete
