Should I 'bridge' my DPC to tank the exterior of my property to protect from flooding?

Hello folks, 

I was flooded in Jan 2025 have recently re-built my house and I am about to get EWI. I should have taken flood protection more seriously earlier, but that ship has now sailed.

Regardless I am about to tank the external of my property, and ideally I want to take the flood protection above my DPC .

I plan to use this https://www.newtonwaterproofing.co.uk/wp-content/uploads/2021/10/Newton_HydroBond_2K-Flex_TDS_1.0.pdf below DPC and approx 30cm under ground level and then https://www.newtonwaterproofing.co.uk/products-systems/products/cementitious-tanking-slurries-renders/high-performance-cementitious-coating/ to 'bridge' my DPC and provide some level of flood protection above it. My thinking being that the cementitious coating will at least somewhat breathable.

See the below diagram for my thoughts, I would just like some input on this? My DPC is very high currently about 40cm off the ground. 

I have dug around the entire of the property and opened up the pavement at the front.
