waterproofing wet breeze blocks

[748rhydhir]

i have a store cupboard under an external stone staircase.
water is coming in so i assume no waterproofing was done during the construction.
is there anything on the maket that can be applied to wet breeze blocks to waterproof them.
regards,
john

Is your staircase made of stone or (concrete) breeze blocks?

Is there earth/soil on the outside of the staircase - ie above the damp proof course level ? If so, you might just need to move this away and once the blocks have dried out, seal with a pva sealant.

Do you have any guttering in this area (downpipes rainwater pipes) - could these be discharging water directly into the area around the staircase ? If so, get the guttering fixed so that the water drains away from the staircase.

breeze blocks with sandstone steps.no soil outside the steps.
no guttering in area.butting onto the staircase & sharing a common wall with the leaking store cupboard is another roofed store that houses the central heating boiler.this room is dry apart from damp coming in from the leaking store cupboard(the water is coming in from the roof area).i seem to remember reading somwhere that there is a compound that can be applied to damp breeze block to waterproof them.
thanks for reply.
regards.

OK, I understand now. I think you will have to dry out the blocks before you can *waterproof* them - either wait for the weather to do this or use a dehumidifier or heater. The compound is probably one of the Aquaseal range - http://www.aquasealeurope.co.uk/

you must dry it out then apply a sealer such as thompsons waterproof brick sealer
