i want to ask questions
may i know the source problems for the criteria below and suggest the correct method to solve the defect:
1. beam or column cracks
2. floor tiles cracks
3. road premix ponding

Answer
Hi Itm,

These could be for various reasons, some of which could be:

1. Due to over-loading or rebar corossion- solution: reduce load, remove concrete cover, apply anti-rust treatment and re-apply cover.

2. Cracking of floor, or lack of movement joints. Solution- as above, or incorporate movement joints.

3. Poor camber or cross-fall. Solution- re-apply premix to proper levels.

4. Waterproofing damaged or slab cracked. Solution, as 1 above, or stripp off old waterproofing and re-apply new.
