Engineering and Material Services

We not only test investigate, but will also repair. We are experts in top down construction, underpinning and emergency repairs of structures. We provide on site support for clients world wide and if required will under take difficult and critical projects.

In testing and investigation of structures the problem arises when there is a need for repair work. Thick reports which usually are a glorified advert for the testing house are not much use unless a solution is given. Typically the usual solution is the classic belt and braces, demolish and rebuild. This is ok for structures built in the late eighties and nineties, but not much use when you get to 1900's structures or even late 1950's structures. Historic or even old buildings require a different approach to their evaluation and repair.

We are experts in concrete manufacture. Our concretes which we have made vary from the normal sand cement and aggregate to special reactive concrete.
Even though there are patented concretes like ours on the market, we are probably the most experienced in their
application and design.

The general name for our concretes is RASC XX or Reduced Aggregate Structural Concrete, XX is the target 28 day strength but actually it is the 3 day achievable strength the characteristics of our RASC40 is that it is self
compacting slump >200mm. Non shrink and very heat durable. Being stronger that most epoxies it is perfect for
grouting in tension bolts for the general name for our concretes is RASC XX or Reduced Aggregate Structural Concrete, XX is the target 28 day strength but actually it is the 3 day achievable strength the characteristics of our RASC40 is that it is self compacting slump >200mm. Non shrink and very heat durable. Being stronger that most epoxies it is perfect for grouting in tension bolts for factory machines in hot places. Most epoxies fail or weaken under heat.

Traditionally concretes get their strengths from the friction bond between the large aggregates in the concrete matrix. RASC gets its strength from the chemical bonding of the constituents in the mix.
Typical application is column strengthening the out shell of RASC is usually designed to be of equivalent capacity to the original total section. As the concrete is placed hot the natural contraction adds to the capacity of the composite column.

This an marine application of the mix. The concrete being self compacting and low bleed, i.e. it doesn't separate when poured under water! is perfect for the environment and provides a lasting repair.
The mix is stable and can be pumped

Another application, The large cavities under the Second Crossing bridge foundations between Singapore and Malaysia were filled with RASC providing a large cost savings to both client and contractors.
