Project Overview

A homeowner and local building team in Penarth, near Cardiff, were constructing a new residential garage. To ensure long-term structural durability and complete protection against rising dampness, the project required a high-quality concrete slab poured directly over a heavy-duty damp-proof membrane.

C&L Ready Mix Concrete supplied the exact volume of premium concrete required, delivering a seamless, hassle-free pour from delivery to final levelling.

The Challenge

Groundwork preparation for residential garage slabs requires absolute precision. The Penarth site presented key requirements:

  • Damp Protection: A clean, carefully laid membrane beneath the pour to prevent moisture ingress from the soil. 
  • Tight Access Logistics: Navigating delivery vehicles and managing site machinery—including a mini-excavator—within a residential Penarth neighbourhood. 
  • Flawless Finish: Ensuring the concrete was levelled quickly and accurately across the entire footprint to create a perfectly flat base for the new garage structure.

C&L’s Solution

  1. Precision Ground Prep & Membrane Laying 
    Prior to the pour, heavy-duty black damp-proof polythene membrane was rolled out across the prepared sub-base to safeguard the concrete slab. The sheeting was secured at the edges to prevent any shifting during the discharge process. 
  2. On-Time Delivery & Controlled Discharge 
    Our C&L ready mix delivery vehicle arrived promptly on site in Penarth. Using the truck's extended discharge chutes, our team poured the fresh concrete directly onto the prepared membrane. This eliminated unnecessary manual wheelbarrow and kept the surrounding workspace clean and organised. 
  3. Expert Placement & Screeding 
    As the concrete was discharged, the ground team spread the mix evenly across the garage footprint. Using professional screed rails and straight-edge levelling tools, the team compacted and flattened the slab to achieve an immaculate, level surface.
