Top-quality polished concreting and house slabs

With Joe De Murtas’s expertise in concreting services and formwork, JCM Construction Group has earned a reputation as a leader in the construction of concrete slabs, driveways, floors and fittings. Concrete finishes are an essential element of homes with contemporary styling, and can help home owners achieve thermal comfort and lower energy bills.

Types of concrete slabs

There are two types of slab-on-ground:

  • conventional slabs, with deep excavated beams
  • waffle pod slabs, which sit near ground level and have a grid of expanded polystyrene foam pods as void formers, creating a maze of beams in between. Waffle pods can be insulated beneath.

Suspended slabs are formed and poured in situ, with either removable formwork or permanent formwork that forms part of the reinforcement.

Pre-cast slabs are manufactured off-site and craned into place, either in finished form or with an additional thin pour of concrete over the top.
