September 20, 20242 yr I’m after some advice please. We’re just going up from the ground beam and have one course below the first damp barrier which the beam&block sits on. The gap alongside of the house will get backfilled with our clay soil. The ground worker is suggesting crushed stone up to this first block course and that we should paint it first with Black Jack. There’s a void inside so in theory the block can breathe under the house and the BJack will stop the outside edge getting as wet. Is this a good idea? Edited September 20, 20242 yr by ChrisInKent
October 3, 20242 yr I’m not sure if I posted it in the wrong BH category, or maybe no one knows the answer? I did do a BH search but there wasn’t a consensus on options: do nothing paint above damp bitumen above damp render above damp brick slip above damp We now also have stainless steel anchor straps in place, so we could hammerite them or just leave block and straps exposed. If anyone has experienced this situation please do share what you did.
