Criblok solutions
Criblok solutions
Gravity retaining walls constructed from a framework of interlocking components to create a grid like structure. The spaces within the grid are filled with graded stone to provide mass and stability. We have a range of materials to specify, dependant on project brief.


Manufactured in the UK
We are committed to supporting British manufacturing, with our products designed and produced right here in the UK.
Timber Criblok
Sustainable retaining wall with natural aesthetic appeal
The timber Criblok retaining wall system is constructed using PEFC certified timber, which is pressure treated to ensure durability and a service life of 60 years.
This modular system is cost-effective and aesthetically pleasing, making it ideal for both small and large retaining structures, with heights exceeding 12 meters.
Each timber crib is machined to an approved quality assurance standard, forming frames that are filled with graded stone. This system provides a natural aesthetic while maintaining structural integrity. Rootlok bags can also be incorporated to create a partial vegetated landscape finish if required.

Plastic Criblok
Lightweight, eco-friendly retaining walls
Manufactured using 100% recycled material, the Plastic Criblok walling system offers an environmentally friendly alternative to timber and concrete systems.
This modular system provides a 120-year design life and is suitable for applications requiring lightweight yet robust solutions. The systems header and stretcher components form cages, which are filled with graded stone to achieve the required mass for structural stability.
Rootlok bags can also be included to create a vegetated finish, further enhancing sustainability and aesthetic appeal.
Plastic Criblok systems are commonly used in residential, commercial, industrial, civil engineering, road-rail, and major infrastructure projects.

Concrete Criblok
Robust retaining walls for high-load application
The Concrete Criblok retaining wall system is a modular, pre-cast solution designed to meet the demanding requirements of high-load and high wall applications.
Concrete Criblok offers a robust and cost-effective alternative to traditional hard-engineered structures, with rapid installation and minimal manual handling.
The system consists of pre-cast concrete header and stretcher components that form a cage, which is then filled with graded stone to achieve the necessary mass and stability.
For projects seeking a partial vegetated finish, Rootlok bags can be used as planters to deliver a more natural greener finish.
With a 120-year design life, this system is ideal for use in highways, rail, commercial and industrial sectors.
