We've a block paving step leading up to our back door (old victorian house). They look like concrete blocks to me.
Below the step is our cellar which is reasonably dry - unless it rains in which case water cascades down through this step. From the underside it's a concrete slab and it's just coming in at the edge/lip of that, dripping in.
So my question is, is it possibly to get a waterproof grout or similar that can be brushed into the joints and then for me to seal the whole lot? Or should i look to lay a paving slab over the whole section (it's circa 1000mm x 1000mm) sealed around the edges with mortar? The step on one side is against a brick wall to what is now the downstairs loo (also above the cellar) and at the front it meets the house via a concrete step.
Any help would be much appreciated as the cellar is a good, useful, dry space were it not for this - and it's a significant amount of water that comes in unfortunately!
