In the region I'm practising, post-installed anchors are considered as somewhat expensive system than cast-in-situ anchors. But, in my openion, there are number of advantages you can gain when using post-installed anchors. Advantages * No need to do tedious setting outs. Just do the casting and...

Hello All, Recently I encountered this issue. Is pre-cast beams with 2.5" thick overlay suitable for a flat accessible roof top? Will water-proofing work on this? Building is 100' long and 50' wide. Ther will be insulation and water proofing. Many thanks, KC

Many thanks! Clefcon

Folks, I am currently constructing my own house. I am thinking of having a cement rendered floor with Titanium finish. The common problem of this is hairline cracks. How can we control these cracks? Even after 5 days water ponding, cracks might appear, contractor says. What are the precautionary...

JAE, Yes, I'm thinking of rebuilding the joint on the top surface. There should be a better way than just plaster??? Many thanks, Clefcon

JAE, Sorry if this is confusing. That cracked beam is a long cantilevered beam. This is the isolation joint they had used.
