Ready Mix Concrete
We produce different classes of concrete in line with our diverse customer needs:
|Class||Grade Mix Ratio (cement : sand : aggregates)||COMPRESSIVE STRENGTH||Recommended for:|
||15 MPa||2175 psi||Suitable as blinding and/or levelling concrete|
|Class 20||1 : 2 : 4||20 MPa||2900 psi||Used for general road drainage works and small-span residential building structures.
|Class 25||1 : 1.5 : 3||25 MPa||3625 psi||Generally recommended for most structural works or as specified by the design structural engineer.
|Class 30||Design Mix||30 MPa||4350 psi||Mostly used as structural concrete in high-rise buildings, especially on columns or as specified by the design structural engineer.
|Class 35||Design Mix||35 MPa||5075 psi||For projects as specified by the design structural engineer.
|Class 40||Design Mix||40 MPa||5800 psi||For projects as specified by the design structural engineer.
Besides these, we also make concrete mix designs for screed mix, shot create, and pavement concrete.
All our mixes are designed to suit the placing methods on-site like skip, chute, pump; and are also designed to meet the required workability specifications.
Poly Fiber Reinforcement
Concrete floors are expected to meet extreme requirements; to have the strength and endurance to resist tensile, compressive and bending forces. Polyfiber reinforcement increases concrete resistance against physical loads, freeze and thaw effects. It alsoimproves the crack resistance of concrete structures, makingthem safer and more reliable over their entire life span; and prevents shrinkage cracks while providing ductility and high-energy absorption.
Our fiber products are designed to advance the performance, durability and aesthetics appearance of buildings and infrastructures. They can also be used for fire resistant and refractory applications.
Recommended for field and ground concretes, dock areas, and packing and loading ramps.
We are the nation’s largest resellers of construction aggregates; that is primarily crushed stone, sand and gravel. We also produce aggregates-based construction materials including asphalt and paving materials, and distribute it across the nation.
These aggregates are used in the construction and maintenance of infrastructure like roads, and other public works projects., as well as in the construction of housing, nonresidential buildings, commercial and industrial facilities. They are also used as railroad ballast, and also have non-construction uses including agricultural and various industrial applications.
Concrete Pumping Services
Over the years, Rhombus has earned a reputation for offering the highest quality concrete pumping services in Kenya. We have the latest, state-of-the-art concrete pumping equipment to effectively manage the biggest projects – even concurrently.
More so, our machinery have an outstanding safety record, and facilitate time-efficient pumping. They also guarantee quality is preserved during pumping, and reduce labor costs.
Waterproof Additives | BASF and SIKA
Waterproofing protects structures against water infiltration which can cause expensive and irreversible damage. The tricky thing about waterproofing is that its need It is invisible during and just after construction. But every day, the basement of your building, or the outermost layer of a tunnel, is exposed to intense fluctuations in moisture levels and temperatures, all contributing to its deterioration.
Sika’s solutions are responsible for keeping water out tunnels, bridges, basements, balconies and drinking water facilities.
These solutions reduce shrinkage, inhibit corrosion, entrain air, accelerate concreate mixture and stabilize hydration – making them important refurbishment, sealing and bonding, flooring, roofing your construction projects.
There are also various solutions for special site conditions, including microbiological and chemical attack resistant products, high mechanical resistance products, free of physically linked plasticizers and ecologically sustainable products.
BASF is a chemical additive for new construction, maintenance, repair and renovation of structures.
Our solutions are recommended for underground construction and building systems, and are crucial for specialized flooring solutions for warehouses, sports venues and car parks as well as medical and fast-moving consumer goods environments.
This solution is customized for various geographical and weather conditions, and as such it boosts structural quality and durability, extending the infrastructure lifecycle and reducing maintenance expenses in the long run.
If you are looking for fast, reliable and trusted concrete delivery services, look no further. We understand that time is money, so we have invested in a massive number of the latest fleet to ensure timely and smooth delivery.
Our trucks are unrivalled, have outstanding safety records and are powerful enough to access even the remotest construction sites. They are also well calibrated to ensure what a client orders is exactly what they get – which builds credibility and helps in customer retention.
