Colinwell Allan Block Retaining Wall 

We work in partnership with Allan Block, to provide the construction sector with industry-leading block retaining wall technology. 

The Allan Block Retaining Wall collection does not require mortar or footings for construction, it is easily assembled using the innovative dry-stack method. This collection also promotes better drainage with the hollow core design, making it an ideal building material for outdoor construction. 

We supply the Allan Block Retaining Wall to both commercial and residential customers. It is available in five different colour options, and is suitable for both landscape and structural construction. 

Colinwell Martello Stone Walling

The Colinwell Martello Stone Walling range is a collection of masonry products that provide a modern and convenient alternative to traditional stone walling. 

Property owners, constructors, etc, can add the traditional charm of a stone wall to a building’s exterior, without having to seek assistance from a specialist stonemason. This type of material is much easier to manage and install. 

The Colinwell Matertello Stone Walling range has been created using innovative technology to reconstitute quarried natural stone, we supply this collection in four different colours. It replicates traditional Irish building architecture and can be laid in a random or straight-coursed pattern.

Colinwell Architectural Masonry Products 

The Colinwell Architectural Masonry Product range has been created using innovative technology, alongside the knowledge learnt from a rich heritage of concrete manufacturing. 

Our Architectural Masonry Products are weather resistant, long-lasting, durable and robust. We provide industry-leading concrete blocks that help maintain the structural integrity of the building. 

The Colinwell collection of masonry products offers a wide variety of styles, sizes and textures. We stock twelve different shades of a smooth finish and sixteen different shades of a split-face finish. The design options are endless, allowing you to obtain a masonry product that compliments the architectural style. 

Colinwell Acoustic Masonry 

With the Colinwell Acoustic Masonry product range, a building can be designed with an inherent ability to manage noise.

Our range of acoustic masonry products helps to manage noise pollution and sound reverberation in the building’s construction. We have a line of quality masonry blocks that can absorb and amplify sound, and redirect noise. 

We have provided this range of Colinwell masonry products to schools, sports centres, music halls, etc, in order to minimise noise pollution and prevent disruption to the surrounding environment.

In some cases, we may be able to provide pallets for transportation, however, this is not a standardised process.
