unheard Posted April 27, 2023 Share Posted April 27, 2023 (edited) I'm about to start a project of concreting my driveway along with the yard. I want to install expansion foam in several joints. Searched for the product but couldn't locate anything similar to joint expansion foam on Lazada. Doesn't anyone have any suggestions? Thank you.

cooked Posted April 27, 2023 Share Posted April 27, 2023 I don't think many people bother. In Switzerland we had to contend with temperatures between -20°C and +40°C. That's a lot of expansion due to temperature. Much less here. Also although I have seen a lot of shoddy concreting jobs, none of the damage seemed to be caused by thermal expansion. I suppose you could buy asphalt in sacks and pack it in the day after concreting when you have removed the pieces of wood you thoughtfully put in every 5 - 8 metres. 1 1 Link to comment Share on other sites More sharing options...

I have yet to see a single example of a foam expansion joint used in concrete work. At least not in residential properties. On lazada I've found large sheets of foam made from the same as pictured material (expanded polyethylene). Link to comment Share on other sites More sharing options...

I'll be good with what I've already found. Will just have to cut a bigger sheet of material in stripes. Link to comment Share on other sites More sharing options...
Encid Posted April 29, 2023 Share Posted April 29, 2023 (edited) The Kingdom of Thailand Ministry of Transport Department of Highways has a set of standard drawings for the saw-cut expansion joints you see them working on for all new major RC roadworks. Here are a couple of excerpts from those drawings which may help: Edited April 29, 2023 by Encid 1 Link to comment Share on other sites More sharing options...

I did something very similar. The weeds grow wonderfully well in the bitumen filled cuts. 1 Link to comment Share on other sites More sharing options...
