WATERPROOF CONCRETE

Our Waterproof Concrete has been designed for low permeability according to the DIN 1048 Standard. Unlike conventional concrete, it has a special property to prevent water from penetrating through its structure. INSEE Waterproof Concrete is recommended for use in swimming pools, wells, underground buildings, roofing slabs and similar demanding applications.

BIG BORED PILE CONCRETE

This type of concrete has been specifically designed for the construction of big bored piles where concrete in its fresh state must have high workability as well as being free from segregation. Big Bore Pile Concrete also has a prolonged working time which helps ensure that each bored pile will be consistent in quality from start to finish.

SMALL BORED PILE CONCRETE

Small Bored Pile Concrete has been designed with an appropriate level of workability and working time. Aggregate segregation is also eliminated by using optimum mix designs and careful selection of raw materials.

Topping Concrete

Topping concrete is mostly used in casting the top layer of structures, which requires a smooth surface after polishing. Therefore, this concrete product has been designed so that it contains a higher proportion of fine aggregates than conventional concrete to assist in preventing coarse rocks that are unsightly from appearing at the surface after the final polishing stage.

Mortar

Mortar (the combination of cement, sand and water) is typically used for floor topping and level adjustment. As well as using conventional placing techniques, our mortar can also be pumped.

ASTM C33

Sulfate
Resistant Concrete

Our sulfate resistant concrete has been specifically developed for structures that are prone to sulfate attack. In order to ensure a satisfactory level of protection against sulfate the two main factors that must be considered during the mix design. The water/cement ratio of the concrete should be less than 0.5 according to ACI 201.2R Durable Concrete Standard. This low water/cement ratio will cause the concrete to be more impermeable thus, preventing water or other chemicals from penetrating. The mix proportion should consist of appropriate amounts of materials in order to prevent the formation of Secondary Ettringite, and Magnesium Hydroxide, which forms Magnesium Silicate Hydrate, which is responsible for the cracking in concrete. For additional assurance, our raw materials have been carefully selected according to ASTM C33 Standard.

Non-shrink Concrete

This type of concrete has been specifically designed to minimize the amount of shrinkage in concrete. A special kind of admixture that is suitable for this type of application is utilized in order to allow the concrete to expand in its fresh state. This pre-expansion will compensate for the shrinkage that will occur when the concrete starts to set, thus reducing the extent of shrinkage in hardened concrete. Non-Shrink Concrete is, therefore, suitable to be used in structures that require the degree of shrinkage to be minimal. Such applications, include, pile cap concrete, roads, and ground slabs that cover a large area.
