Concrete Working Platforms

When it comes to construction projects, selecting the right method for ground preparation is essential to ensure safety, stability, and cost-efficiency. For sites with a CBR (California Bearing Ratio) of 2% or greater at the formation level, using concrete blinding in place of traditional granular piling mats offers several advantages.

Why choose concrete blinding over piling mats?

Concrete blinding offers a more sustainable cost effective solution for foundation installation over the traditional piling mat. Explore the top four reasons to choose concrete blinding below:

Compliance with BRE470 Standards

Our concrete blinding platform is compliant to BRE470, the recognised manual for temporary platform design.

Significantly Thinner Application 

A key advantage of using concrete blinding is its thickness of only 50mm, compared to the 300mm or more typically associated to traditional granular piling mats. This reduced thickness translates to faster installation, less muck away, reduced material spend and less risk to the project timeline.

Reduced Environmental Impact

By using concrete blinding, you significantly reduce the volume of muck away from the site, whilst substantially reducing the number of vehicles needed to import stone, lowering both disposal costs and the environmental impact.

Lower Plant and Labour Costs

The use of a Concrete blinding platform substantially reduces labour and plant costs associated with excavation, importing aggregates, levelling and compaction and redressing, this resource can be reallocated elsewhere whilst the concrete platform is installed.

Benefits of our concrete working surface

Step 01:

Eliminates the need for an engineered mat

Our Concrete Working Surfaces eliminate the requirement for an engineered piling mat, traditionally requiring between 300-500 mm of crushed concrete.

The concrete working surface also as a working platform to facilitate the construction of our reinforced concrete slab.

The additional benefit of using a concrete working surface is that in the event of adverse weather, the working area becomes sealed. This maintains site productivity whilst promoting a clean and safe working area.

Step 02:

Formation preparation

Our clients groundworks team will typically complete the reduced level dig to the proposed area of the plot including, 1mtr working space.

Once the formation has been prepared accordingly, SPEEDECKs site engineer will set out the plot area ahead of the concrete installation.

Step 03:

Installation of concrete blinding

Concrete blinding consists of a layer of plain concrete, usually 50 to 100 mm thick,  laid over the compacted soil surface before the actual foundation construction begins.

This foundational process ensures stability and durability for the structure, making it a fundamental aspect of our construction projects.

Our in house concreting team install concrete blinding to the necessary depth, typically below the frost line, to ensure stability. After excavation, soil compaction and levelling, a layer of blinding concrete is laid over the prepared soil surface. The concrete is evenly spread and compacted to achieve uniformity in thickness.
