A small low-level boardwalk

A small low-level boardwalk

IMG_0675.jpegAs low decks seem to be a constant subject of interest I thought this was worth sharing as a slightly different situation.


We needed an elevated entry to a new door into our house from the driveway. Being a very level block and having high rainfall it had to provide a dry entry. There is a very small amount of slope in the area so the gravel ensures water can easily flow.


I wanted the deck to be at the same level as where the first step-tread should be on the stringers. That meant I needed to install the first step-tread upside down (underneath).


Due to its position beside the drive in an area that is used for 3-point turns I didn't want to put the edge of the deck right on the edge of the drive as I knew it would be reversed into hence the setback.


Not finished yet as I need some merbau treads & they are impossible to find at the moment and once I have them in I'll dress the side to conceal the stringers & I'll fill the riser gaps too.


I just thought the stages of ensuring clearance may be of interest.

Re: A small low-deck boardwalk...

Many thanks for sharing this process with us @Adam_W. It's beneficial in visualising how the soil should be prepared and adequate clearance established on a low-level deck. 

 

The river gravel looks fantastic and is a nice finishing touch. Make sure to update us once those Merbau step treads are in.

 

Great work.

Hello @Adam_W 

 

It's always a treat to see your handy work! For me it's always a learning experience as I did not imagine you could build a small low level deck in this manner. Looking forward to the next build and learning more! 

 

Cheers, 

Red

Hey @Adam_W @can you show a photo of what stirrups you used and how they are concreted? Many thanks

Hi @th-DIYER I didn't get any close-ups of them.
I had to use these, centre-fix stirrups, as for some inexplicable reason my local Bunnings doesn't stock half-stirrups.
Very rudimentary diagram below of how I fixed them in.
