What room is it? I'd suggest if you feel getting rid of the flooding completely won't happen or is to expensive would be too tile the floor and also do a skirting out of tiles perhaps 150mm high. Atleast the gybrock walls and whatever the floors are won't be getting ruined.
Weatherproof right around the edges also. Not ideal but it atleast means can dry it up.
The only other option that maybe possible could be a hedge/plants where the water is falling at the side of house. Atleast the shrubs will help suck the water out of the ground and dry it out faster.
Our house is a 4 bedroom place; the garage is the first room, then my room, then the next three room, then the living room, then the backyard.
It's my room that floods.
The plumbers reckoned it had to do with the seep holes being too low; the water would pool up, and seep into the seep holes, and into the house.
They dug out a lot of soil, which was laden with clay (explaining why the water would not drain), added some drainage, replaced the soil, added some blue metal, and relaid the whole lot back.
Honestly, they did a great job.
It's just that the design of the house is totally imbecilic.
