How to seal the bottom of shed walls?

Hello, anyone have any suggestions as to what I could do to seal the bottom of the shed walls? Sand and debris keep coming in and building up. It is a metal shed with a concrete slab, the walls are also staying to rust at the bottom.

Re: Seal for shed walls

Welcome to the Bunnings Workshop community @jjebw. It's fantastic to have you join us, and many thanks for your question about sealing your shed from the weather.

Looks like a perfect job for Sikaflex 11FC. It is a flexible jointing sealant designed to stick to concrete and steel. It'll seal that area well and is far superior to silicone. Just make sure you give the area a thorough clean before caulking it along the gap and seam between the floor and wall. If the steel is beginning to rust, it would be a good idea to seal the outside to stop water from migrating under the sheeting. 

 

Please let me know if you have any questions.

Re: Seal for shed walls

Can also recommend Sikaflex, I just used it recently when renovating our shed. Best advice is wait a couple of days after rain and clean it throughly. Apply a generous amount to the inside, clean as required. Apply a smaller amount to the outside, clean as required. Don't do it on a rainy day, try to do the project when you have at least another day of sunlight to allow it to seal properly.

Re: Seal for shed walls

Hello @jjebw 

 

Would it be possible for you to post a picture of the other side of the shed wall? Is soil gathering on the face of the wall? Is vegetation overgrowing in that area of the shed? Is there a retaining wall next to the shed? I understand these are a lot of questions. But I'm proposing to look at the source of the water and perhaps pre-empt it from reaching your shed wall.

 

Standard solutions include putting in Vinidex 65mm x 20m Draincoil With Filter Sock or Everhard 3m EasyDRAIN Polymer Grate And Prejoined Channel. My only concern is that if we don't address these possible causes more water will enter your shed.

 

If you have any other questions we can help with, please don't hesitate to post them.

Re: How to seal the bottom of shed walls?

Thanks for all the tips everyone, project took a couple of months. I used the Sikaflex and dug a trench around the side and put in some draining grates so hopefully it'll stop the rust.
