Yes, but not this product.Use AFM Dynoseal for the inside only of raised garden beds or ceramic or masonry surfaces. This waterproofing membrane can withstand constant moisture even below grade.Use GBS Penetrating Concrete Sealer to seal the outside of concrete, brick, masonry surfaces. This will penetrate deep into the surface and permanently block moisture intrusion from the outside. However, it is not meant for submerged surfaces. The concrete must be clean, dry, porous and cannot be previously sealed or painted.
