Browse Forums Landscape & Garden Design 1 Mar 17, 2009 9:56 pm I am fixing up our old Pond which is going to have a Crepe Myrtle planted in it. I pulled off some old tiles on the Pond edge...now it's quite uneven and bumpy so I'm going to smooth it out,
As you can see in the pic below, I've started to box it up. My question is, what should I use to fill up the space between the formwork. It's only about a centimetre deep in some spots. I had thought concrete but wouldn't the pebbles in the concrete mix come to the surface on the shallow spots? I was also wondering if I could use a mortar or sand/cement mix to do it but I guess that may be more prone to cracking. Any advice greatly appreciated.

I have seen it used for filling pot holes in concrete slabs with forklift traffic and it works just fine. Re: Mortar, Sand & Cement or Concrete? 5Mar 19, 2009 6:25 pm yeah it's fine. In fact it was the only thing that lasted. when ever they filled the holes in the concrete with cement (bondcrete used) it would crumble away in no time with the forklift traffic. The floor leveller has lasted great with heavy traffic on it. Never comes apart so it will be fine for your purpose Re: Mortar, Sand & Cement or Concrete? 6Mar 23, 2009 6:20 pm use a 3 to 1 ratio washed sand and gp cement with crommlins acrylic cement modifier in it and a small amount of plasticiser paint the surface to be coated with acrylic then apply the render mix, it will take app. 2 weeks to fully harden off but it will be sufficient for what you need level compund has a mpa of around 90 and is extremely strong but is not suitable for vertical surfaces, look at non shrink grout if you dont want to use above render mix also bond crete is water based and breaks down over time in exterior situations also tank the inside of planters as negative hydro. pressure will deteriorate the render from the inside out and have sufficient drainage Da Vinci Outdoor Living Architectural landscaping http://www.davincioutdoor.com Re: Mortar, Sand & Cement or Concrete? 7Mar 23, 2009 7:12 pm Thanks for the advice guys. I ended up using the 3 to 1 ratio of brickies sand and portland cement...with some bondcrete added to the mix. Has come up an absolute treat. I just need it to harden a bit more but I'll be painting the inside of the box with the black pond seal type paint. 2 8872 Hi, Currently building, we are on a sloping block so we have from floor level to the roof in axon cladding.
