I'm about to erect a greenhouse onto a breeze block foundation and I'm wondering if anyone can recommend a cushioned tape or material of some kind to put between the base and foundation to cancel out any tiny bumps and hollows and make for a better seal.
The greenhouse base is 2 inches/5 cm wide.

Hi @MrNumty and welcome to the forum. How about a hefty bead of a good silicone caulking? Not only will that create a good seal, but it will keep any water from seeping into your greenhouse.
