Browse Forums Outdoor Living 1 Nov 09, 2010 12:02 pm Hi, we will be getting Modwood (Wood Composite Decking) installed in our alfresco area. Currently we have a concrete slab which has three sides surrounded by the house (brick veneer) and one side which is open (back yard). Modwood needs to have at least 50mm of space underneath, which is to aid in water flow/drainage etc. So what we're doing is using battens approx 117mm in height. The reason being is we want the Modwood to be level with the inside of our house which is 140mm in height (117mm (battens) + 23mm (Modwood) = 140mm). It's also recommended to use 6mm gaps between the Modwood boards when fixing over concrete, so we'll also be doing this. This also includes a 6mm gap between the brick and Modwood on those three sides. However, what I'm getting confused about is the open side (where the deck will face the back yard). After this decking has been installed, we'll be putting in an inground fibreglass pool. The pool area will be natural stone tiles (most likely travertine or sandstone). The plan is for the tiles and decking to meet (will be no yard in between). Initially, we wanted the pool (and the pool area tiles) to be level with the decking. We can do this with the aid of the pool builders and landscapers so no real problems with this (as far as I've been told). My question is will making this level with the decking cause issues for the Modwood - drainage etc.??? Because basically this means that there will be soil spread out (from the pool excavation) so it raises the turf approx 120mm...that way the tiles will be level with Modwood. So any water that accumulates under the Modwood (onto the concrete) won't have anyway to go because there will be soil adjacent to the space underneath the Modwood. Does this make sense? I'm guessing this could cause issues or am I over analysing? Our alfresco area is obviously covered and we don't get too much water under there anyway. When it rains very heavily we might get a little bit but usually not too much. We also get a few leaves and bark etc. from the back yard which currently makes its way onto our concrete. With Modwood this stuff would probably stay underneath for ever.. Alternatively, we could install the Modwood and don't worry about making the pool/pool area level with it. This means the tiles would be lower than the decking (by approx. 120mm). Would this work better? We're just worried this won't look very good. If we have to do this, we'd probably revisit whether we also get tiles on top of the concrete as opposed to Modwood. Anyone have any feedback/suggestions? Also, we'll be getting semi-frameless glass fencing where the tiles and Modwood meet. Not sure whether this fencing will be installed on top of the Modwood or tiles...will consult with the fence guy when the time comes. Re: Alfresco Floor (Modwood Composite Decking) - Question 3Nov 13, 2010 5:41 am Install a strip drain on the concrete level, below the mood wood. You will get a lot of water from the pool area. Go the wider boards with the decking as the gap seems to be more aesthetically pleasing Landscape Design & Construction http://cherub.squarespace.com/ Re: Alfresco Floor (Modwood Composite Decking) - Question 4Nov 13, 2010 10:02 am Thanks Cherub. Who would I speak to in order to get a strip drain? Landscaper? Builder? Plumber? What would I expect to pay for this? Yes we have already decided on the widest Modwood boards so the 6mm gaps don't look as bad. Re: Alfresco Floor (Modwood Composite Decking) - Question 5Nov 14, 2010 5:26 am You could use one of products in link, http://www.enter-shop.com.au/catalogue/c2/c11/p347 Landscaper or Plumber could install. Price on installation would depend on site Landscape Design & Construction http://cherub.squarespace.com/ Re: Alfresco Floor (Modwood Composite Decking) - Question 6Nov 14, 2010 9:17 am Thanks cherub...I'll take this into consideration and speak with a landscaper before we get the Modwood. Looking at the dimensions of those items though (in the link you provided), they may be too tall to fit under our Modwood. Re: Alfresco Floor (Modwood Composite Decking) - Question 7Nov 14, 2010 3:35 pm Drain is actually installed below ground, ie would be flush with surface in your instance. Landscape Design & Construction http://cherub.squarespace.com/ Re: Alfresco Floor (Modwood Composite Decking) - Question 8Nov 23, 2010 6:26 pm Cherub (or anyone else who may know the answer), As I mentioned in my first post, we want this deck to be 14cm off the ground so it's level with the inside of our house. We have brick veneer and approx. 1 brick up there is vertical gaps in between the bricks (these gaps appear a metre or so apart). I'm pretty sure these gaps aid in the ventilation of moisture etc. If the decking is 14cm off the ground, approx. half of each one of these gaps will be under the deck. ie. half of the vertical gap between the bricks will be above deck and the other will be below deck. Is there any issues with this? As Cherub suggested above, we'll also be installing a strip drain on the concrete before the deck is built. Thanks!!!!!!!!!!!!! Re: Alfresco Floor (Modwood Composite Decking) - Question 9Nov 25, 2010 4:24 am Gaps are weep holes, they allow moisture if any to escape from the cavity. Building an elevated deck is not such an issue as long as they are still open, however your damp course will be below the weep holes and also your termite barrier (if any) so consideration must be given to those also.

We are thinking what to use and would lov two see pictures. We are thinking of mod wood next to the alfresco and then maybe modwood around pool, not sure if we should use silver travetine as coping or if modwood looks any good right next to the pool Hi, as per the subject. Does anyone have any recommendations for the best value decking oil (Bunning is close to where I live) for a treated pine deck?
