Construction Site: Freshly Poured Concrete Slab With Steel Framework and Workers — JDC Concreting in Grafton, NSW

Creating Solid Foundations

A house slab sets the standard for everything built on top of it, which is why getting it right from the start matters. At JDC Concreting, we construct house slabs across in Grafton with a strong focus on site conditions, levels and long-term stability. We understand that no two blocks are the same, so we take the time to assess soil, drainage and access before any concrete is poured. By planning carefully and preparing properly, we help reduce the risk of movement, cracking and costly issues later on. Our process is clear and well organised, giving homeowners and builders confidence at every stage.


A well-built slab provides a reliable foundation for the life of the home. Call us on 0499 869 093 to discuss your house slab requirements and arrange a detailed quote.

Frequently Asked Questions

  • How do edge beams affect the long-term performance of a house slab?

    Edge beams play a critical role in supporting external walls and managing ground movement around the perimeter of a home. Their depth and reinforcement are designed based on soil conditions and load requirements. If edge beams are undersized or poorly formed, cracking and wall movement can occur over time. Getting this right helps the slab handle both structural loads and soil reactivity.

  • Why do service penetrations need to be planned before a house slab is poured?

    Plumbing and electrical penetrations must be positioned accurately before concrete is poured. Cutting or drilling a slab later can weaken reinforcement and compromise structural integrity. Poorly placed penetrations can also cause layout issues during framing. Early coordination helps avoid costly rework and structural risks.

  • How does slab curing time impact the framing stage of a build?

    Although concrete sets quickly, it continues to gain strength over several weeks. Starting framing too early can place stress on a slab that hasn’t fully cured. This may lead to surface damage or movement that affects wall alignment. Allowing appropriate curing time helps the slab reach its designed strength before construction loads are added.
