Browse Forums General Discussion 1 Jun 25, 2013 1:20 pm We are still in the early stages of our house design. I'm after some thoughts if there is any difference using pavers or concrete to protect the slab? Our current house has paving, but to me it seems that water can get through there more easily than concrete. Any issues/benefits of using concrete or paving? Thanks! Re: Concrete or paving around slab 2Jun 25, 2013 2:34 pm When we built part of the warranty stated that perimeter concrete paving had to be installed to avoid water ingress to the footings or we risked the warranty becoming void Arfur Re: Concrete or paving around slab 3Jun 26, 2013 1:43 pm Thanks... i thought concrete paving is the way to go too. I'm just a bit puzzled as to why our current house (circa 2005) has paving instead of concrete as it wouldn't provide as much of a barrier for water. Re: Concrete or paving around slab 5Jun 27, 2013 3:32 pm You can always do 75mm slab as primary foundation protection and then have it as base for pavers, just make sure your levels and grades are OK Foremost Building Expert in Australia,assisting with building problems/disputes, building stage inspections,pre-contract review advice for peace of mind 200 blogs http://www.buildingexpert.net.au/blog Re: Concrete or paving around slab 7Jul 01, 2013 9:22 pm I have been wondering the same thing as we are about to build and have been reading the Csiro guide lines. I was wondering about doing pavers to and using a good road base under them with the correct fall. Any more thoughts and would doing pavers that way be cheaper then concrete ? Re: Concrete or paving around slab 8Jul 02, 2013 5:53 am Road base is porous material and would not be a good option. You need protective apron with impervious material.

As 2870 talks about unsuitability of granular fill around reactive soil sites.

This! You can even have loose pebbles, cobble stones, or something else if you go this route. Edit: From my (granted, quite limited) reading of various rules, there is nothing to stop you from having the watertight apron be at a lower level than the actual surface. It's to stop water falling in around the foundation/slap and creating havoc down there. So as long as you get something sturdy that directs the water away from that, you are good to go. Re: Concrete or paving around slab 19Jul 06, 2013 10:56 pm I'm getting concrete around the slab. Fortunately I've found a good concreter, his concrete slopes the correct way and drains off into a drain near the garage. And around the rest of the house will just slope away from the house slab itself. Not recommended! The image presented is for a sublevel area. The footings are down deep with a load bearing wall supporting the upper floor level. If you did that drain… 8 11095 As most others have posted above the install isn't compliant. The pipe is meant to be covered in loose soil or sand, the pipe has holes in it that leaks out a termicide… 10 6133 Grab a hose, insert it at the top of the inlet/down pipe and turn the water on and see where the water is escaping from. Then you'll know. 3 9332 |
