Browse Forums Paving & Concreting 1 Oct 03, 2009 8:36 am I am currently undergoing some paving and coping around our new pool. The pavers and bullnose we have chosen are cream. I have been told that the job requires an expansion joint between the coping and the paving to allow movement. The builder is telling me that the only colour the expansion foam comes in is black. Is this correct? In all the magazine photos I find I cannot see any "black" expansion joints around these pools. Does anybody know what other options I have to match the expansion joint to the paving so that it doesn't stand out as much. Thanks in advance Re: Pool paving and coping - Expansion joints 2Oct 04, 2009 1:08 pm HI Interesting, Normally in a construction expansion joint you would have closed cell foam or PF Rod as its known. Dont see why you would need this in between coping and paver unless you have got a massive distance to the sub base. Usually some would put paving sand up to a depth of say 15 mm from surface, From there i would use Chemseal CR from Parchem www.parchem.com.au as the sealant. Use a 10width x 15 depth joint. This sealent is excellent as it deals with chlorine and has excellent elongation. this means it can stretch and handle a good amount of movement, way more infact that you pool is capable of. I have used it many times in Public swimming pool area, comes in white, grey and black i dnt work for Parchem i help consult for them Regards Re: Pool paving and coping - Expansion joints 3Oct 05, 2009 5:33 pm The best way is to lay a concrete slab base under the poolside paving, 100mm thick. Pin it to the concrete pool shell with rebar but before concreting, lay the expansion foam inbetween the 2 concrete surfaces. They will both expand at different rates therefore you will need some form of expansion medium to allow for it. Once the paving is done you can fill the gap between the paving and the coping tiles with an adequate outdoor salt/chlorine resistant flexible caulking that comes in a range of colours. Just make sure that the mortar the paver is laid on doesnt bridge the gap between the 2 concrete surfaces or it will render the expansion joint a bit useless. It's advisable to also put more expansion joints in your paving at 4m intervals to allow movement with expansion in pavers/concrete around the pool Hi All, First time poster. I was hoping to get some advice on villaboard installation within a bathroom. I have installed villaboard before, in a laundry.

The pipe is meant to be covered in loose soil or sand, the pipe has holes in it that leaks out a termicide… 10 5730 |
