My kitchen of 6 years using solid surface, water start to seep throguh joints to the wooden cabinets below.
My parents now doing up their 2-room flat. My mum insisted on using concrete/bricks because her old house kitchen using concrete can last for > 20yrs.
I happened to kay-poh around when the contractor doing the conrete works for my parent's new kitchen. The worker first over-turned the sink, then apply cement around to create the mould. He even put steel rods through the cement to further stregthen the mould!
When solidified then proceed to put the sink on concrete bricks supoort.
Using concrete might not be as aesthetically appealing as other modern materials, but not very ugly also lah...just a bit old school...but **** solid.
