Browse Forums Building A New House 1 Sep 08, 2017 10:17 am Hi all, My builder just quoted me $5000 to upgrade to 3 phase for our currently constructed house in Melbourne. That's from the street to the house (less than 10 metres). He said it's going to cost more later. I plan to do it after hand over before I lay down the concrete. Is it really going to cost more to do it later? Thanks 1 62023 You can wash over existing pavers with 10% solution of water and hydrochloric acid, then wash off. The acid will provide for required bond key with new concrete. 1 36960 0 9812 |
