Expanding gaskets for segments
Swellseal hydrophilic expanding strips
Swellseal 3V and Swellseal 8V hydro-swelling rubber strips are available in a wide range of shapes and sections for sealing smooth construction joints and joints between precast concrete segments. Using Swellseal Mastic WA as adhesive, the Swellseal strips can be applied to most common construction materials. Swellseal 3V/8V strips have a delayed initial expansion to allow installation in rain or inclement weather conditions.
Our admixture solutions:
- Swellseal® 3V and 8V
Our services:
- Expertise to develop sizes and sections according to project design and requirements.
Fibers
Save time, money and CO2 on the jobsites and increase durability of concrete
Our wide range of solutions for Fiber Reinforced Concrete enables :
- Time and cost savings vs. traditional steel mesh solutions
- Facilitate labor and training
- Reduce elements weight and save on transportation
- CO2 footprint reduction & Enhanced durability vs. corrosion
- Our anti-spalling fiber solutions benefit from optimal cost-performance ratio
Because each precast element is specific, our experts will perform a structural study and recommend the right fiber, the dosage rate.

Superplasticisers for tunnel segments
CHRYSO®Tera range: Optimization of tunnel segments production
CHRYSO®Tera is a solution to answer specific challenges of tunnel segments production.
In addition to the traditional concrete performance indicators (workability retention, reduced water consumption, ease of handling, mechanical strength, etc.), the innovative approach of CHRYSO’s teams focuses on 3 performance indicators specific to the production of tunnel segments:
- Proper placing of the concrete (faster and optimised mould filling, vibration behaviour)
- Concrete levelling (rounded mould – achieving an even surface)
- Finishing quality (easier and faster finish of the extrado)
Our admixture solutions:
- CHRYSO®Tera
Our services:
- CHRYSO®Tera Lab: The CHRYSO®Tera offer stands out in its customised support, from the diagnostics phase to project completion.
Curing agents
Improved concrete hydration and durability
When concrete is submitted to brutal hydration and high temperatures, the use of curing agent helps preventing plastic shrinkage induced cracking and enhances concrete durability; It is even more important in the case of large elements where reinforcement may deeply embedded in concrete and far from its surface.
PIERI® Easy Cure and Curing product range include some high-performance curing agents, easy to apply and very respectful of both users and environment. Some of these products will also durably reduce significantly concrete’s surface porosity.
Our admixture solutions:
- PIERI® Easy Cure
- PIERI® Curing TP 2002
Our services:
- Spraying equipment
- Application Audit and Training (Adequadem program)
- CHRYSO®Maturix (concrete monitoring)
Demoulding agents
Forms shelf-life, flawless facing and safety while respecting the environment
Our large range of release agents benefits from years of expertise and R&D. It includes several products specifically designed for Tunnel Segments and adapted to high curing temperature.
To further increase the shelf-life of your forms, take advantage of integrated corrosion inhibition technology and reduce your environmental footprint through the use of vegetal and biodegradable release agents.
To ensure optimal consumption and performances, our experts will recommend the spraying equipment adapted to your process and can provide specific personnel training (Adequadem program).
