Products
Our Products include: Concrete & Pumped concrete, mortars and plasters, Grouts, Lightweight Concrete as well as Pool Mixes to name a few.
All our standard concrete mixes have been designed to meet the requirements of SABS 1200G Table 5.5.1.5 Mild Exposure.
We offer many different types of mixes. Special concrete mixes can be done to meet specific contract specifications. All materials comply with the relevant SABS standards.
Our SABS 0164 Class I, Class II and Class III mortars provide the ALL IN approach to supply of wet products for most construction sites.
Basics of Concrete | Aggregate
The term "aggregate" denotes a wide range of granular materials that may be used in the production of concrete, such as:
- Gravel
- Crushed Stone
- Natural Sand
- Manufactured Sand
- Coarse Aggregate
These are basically divided into two categories: Fine Aggregate and Coarse Aggregate based upon their particle size.
- Fine Aggregates consist of particles smaller than 1/4", usually sand or crushed stone
- Coarse Aggregates are those with particle sizes larger than 1/4"
- Aggregates make up 60% to 80% of the concrete volume

Overview: Surface-applied cementitious or admix waterproofing material for concrete structures.
Product Description: Penetron is a surface-applied, integral crystalline waterproofing material, which waterproofs and protects concrete in-depth.
It consists of Portland cement, specially treated quartz sand and a compound of active chemicals. Penetron has no added solvents minimising net VOC emissions.
When product is applied onto a concrete surface, the active chemicals combine with the free lime and moisture present in the capillary tracts of the concrete to form an insoluble, crystalline structure.
These crystals fill the pores and minor shrinkage cracks in the concrete to prevent any further water ingress (even under pressure). The concrete dries out but remains vapour permeable, preventing the growth of toxic mould in enclosed spaces.
It can also seal cracks of up to 1/64’’ (0.4mm) rather than masking or bridging them. It also protects the concrete against seawater, wastewater, aggressive ground water and many other aggressive chemical solutions.
Penetron is approved for use in contact with potable water and is therefore suitable for use in water storage tanks, reservoirs and water treatment plants.
