Anybody know of any product like the black membrane that it used under a oversite(concrete slab) like in UK building that is available in Thailand?

Thanks in advance

Ask where you buy your concrete.

Why do you need it.? 

Would pond liner do the job?

Yes. Thank you

 

In 2020 it was readily available from a motivated Sika dealer in Thailand. Sika has "merged" with Parex in late 2020 so I have not asked for this product in 2021.

In January 2021 there are rolls of plastic water vapor barrier sold in better home builders merchants store. Different thickness of the plastic sheeting and very affordable. I buy rolls of this plastic sheeting when I pour a carport or ready mixed concrete driveway. black or clear. 3.6 meters by 45 yards long.  Under 1700 baht per roll of waterproof plastic barrier in Buriram. 

 

Dr. Fix it and Lanko offer all manner of waterproofing products in all parts of Thailand. Often a large builders merchants store will have a Dr. Fix It representative or a Lanko representative commonly called a "P.C.".
