Hi - Im looking for some advice. Recently put down some self levelling compound in detached garage, single skin. Before putting the SLC down I had noticed small amount of rain water coming under the personnel door but it didn't look like much but now it's come in covering half the garage.
Is it plausible the water is now more noticeable due to the SLC finish versus the rough concrete? Absorbent etc?
I can't see how putting SLC down could have caused the problem? I am not experienced in this type of stuff so advice appreciated.
If the leak is just more noticeable any ideas how I can find out what the problem is? House is only 2years old. As mentioned it is under the personnel door. I can't see where it's coming in whilst it's raining.
Hi cyrill5 Presumably your door has a cill and this has been fitted ontop of your finished garage floor. If your SLC has a feathered edge along the cill then the SLC being non porous you would get the appearance of more water ingress. Suggest you run a bead of silicone mastic along the floor/cill join and see if this reduces the problem. Regards S
Hi cyrill5 What you do will depend on the position of the DPC relative to the garage floor, whether there is a DPM in the floor and whether the walls are built direct onto the floor slab. If the walls are built on the slab (rather than on their own foundations) you will find it very difficult to stop water ingress. Regards S
